How industrial biocatalysts are driving cost-competitive, low-energy PET recycling
The article discusses advances in enzymatic recycling of polyethylene terephthalate (PET), highlighting how engineered biocatalysts are enabling cost-competitive and energy-efficient recycling processes that can rival virgin PET production. Traditional mechanical and chemical recycling methods face challenges such as polymer degradation, inability to process colored or multi-layer plastics, and high energy consumption. Enzymatic recycling uses specialized enzymes to break down PET directly into its monomers—terephthalic acid and ethylene glycol—allowing for a closed-loop system that produces virgin-grade PET. Notably, a process developed by the US Department of Energy’s National Renewable Energy Laboratory (NREL) in partnership with the University of Portsmouth achieves recycled PET at $1.51/kg, undercutting the typical virgin PET cost of about $1.87/kg, while reducing energy and chemical use by over 99%. A critical hurdle for enzymatic recycling is the heterogeneous nature of real-world PET waste, which includes colored bottles, mixed polymers, labels,

Researchers from the University of California, San Diego, and Unigrid Battery have developed a tin-based anode for sodium-ion batteries (SIBs) that significantly improves energy density, surpassing commercial lithium iron phosphate (LFP) cells. Their design achieves 178 Wh/kg and 417 Wh/L in full pouch cells, representing a record efficiency using sustainable, low-cost materials. The anode is composed of 99.5% tin, with minor additions of single-walled carbon nanotubes and binder, creating a conductive and mechanically stable structure that overcomes previous challenges of volume expansion and electrolyte incompatibility common in tin anodes. This innovation addresses the traditional limitation of sodium-ion batteries, which have lagged behind lithium-ion systems due to lower energy density, primarily constrained by hard carbon anodes. Tin anodes can theoretically store nearly three times more charge (around 847 mAh/g) than hard carbon anodes (~300 mAh/g). The new tin anode demonstrated excellent cycling stability

Researchers have developed the world’s first flow battery powered by vitamin B2 (riboflavin) and glucose, inspired by how the human body generates energy from food. This bio-inspired system uses riboflavin as an electron mediator to transfer electrons between electrodes and a glucose-based electrolyte, producing electricity from sugar. The prototype employs carbon electrodes and natural, non-toxic, and inexpensive materials, offering a promising alternative to conventional lithium-ion batteries by being safer, cheaper, and more environmentally friendly. The study tested two configurations: one using potassium ferricyanide and another using oxygen as the positive electrode. The potassium ferricyanide cell demonstrated power density comparable to commercial vanadium flow batteries, while the oxygen-based cell, though slower and prone to riboflavin degradation under light, showed potential for cost-effective large-scale production. Future work aims to address the vitamin’s light sensitivity and optimize the flow cell design. This riboflavin–glucose battery represents a significant step toward sustainable, biodegradable

Researchers at McMaster University have developed an innovative menstrual cup that enhances period care by combining hygiene, sustainability, and health monitoring. Central to this advancement is a flushable seaweed-based tablet that can be inserted into the existing Bfree Cup, a lubricant-infused silicone cup that naturally repels viruses and bacteria. The tablet improves usability by absorbing menstrual blood to reduce spills, addressing a common challenge with menstrual cups. This combination offers a more hygienic, eco-friendly, and user-friendly alternative to traditional menstrual products, with the potential to reduce period poverty, especially in low- and middle-income countries where access to safe menstrual care is limited. Beyond improving convenience and sustainability, the researchers envision future versions of the cup equipped with biosensors capable of detecting early signs of infections and blood-borne illnesses, effectively transforming the cup into a wearable health monitoring device. This proactive approach could enable earlier diagnosis of conditions such as endometriosis and urinary tract infections, representing a significant shift from reactive to preventive women’s health care

Researchers at Georgia Tech have developed an innovative mechanochemical recycling method to efficiently break down polyethylene terephthalate (PET) plastics without the use of heat or solvents. PET, widely used in bottles, packaging, and fibers, is difficult to recycle due to its strong molecular bonds, leading to significant plastic waste accumulation. The team, led by Kinga Gołąbek and Professor Carsten Sievers, utilized metal balls to apply mechanical impacts to solid PET pieces, generating enough energy to trigger chemical reactions with sodium hydroxide (NaOH) at room temperature. This approach enables the decomposition of PET into its original molecular components in a controlled and energy-efficient manner, potentially transforming plastic recycling into a more sustainable process. Through controlled single-impact experiments and computer simulations, the researchers mapped how collision energy disperses through PET, causing structural and chemical changes in localized zones. These impacts created micro-craters where PET chains stretched and cracked, facilitating reactions with NaOH, and even mechanical force alone was sufficient to break some molecular

Researchers from Japan have developed a novel biodegradable plastic, called LAHB (lactate-based hybrid polymer), that can degrade in the deep ocean—addressing a major environmental challenge where conventional biodegradable plastics like polylactide (PLA) fail. While PLA is widely used and compostable at high industrial temperatures, it does not break down in marine environments because marine bacteria lack the enzymes to recognize and degrade its molecular structure. In contrast, LAHB combines lactic acid from PLA with 3-hydroxybutyrate (3HB) from polyhydroxybutyrate (PHB), a naturally occurring polyester that marine microbes can digest. This hybrid polymer maintains material strength while being susceptible to microbial degradation in deep-sea conditions. The breakthrough stems from engineering Escherichia coli bacteria to biosynthesize LAHB by inserting genes for a lactate-polymerizing enzyme, enabling the production of a plastic that balances durability with biodegradability. Marine bacteria have evolved depolymerase enzymes that

Researchers at China’s Northeast Forestry University have developed a novel bamboo-based bioplastic that combines exceptional mechanical strength with rapid biodegradability. This new material, produced through a non-toxic, alcohol solvent-based process that dissolves and reorganizes bamboo cellulose at the molecular level, exhibits tensile strength of 110 MPa and a flexural modulus of 6.41 GPa, outperforming many commercial plastics such as polylactic acid and high-impact polystyrene. It also offers superior thermal stability above 180 °C and can be processed using conventional industrial techniques like injection molding and machining. Unlike traditional bamboo composite plastics, which often have inferior mechanical properties and incomplete biodegradability due to their fiber-resin composition, this bamboo molecular plastic fully biodegrades in soil within 50 days and supports closed-loop recycling with 90% retention of strength. Published in Nature Communications, the research highlights the material’s potential as a sustainable, high-performance alternative to oil-based plastics, addressing both environmental concerns and industrial application demands

Researchers at the University of Sharjah in the UAE have developed and patented a novel technology that transforms spent coffee grounds (SCG) from Starbucks in Dubai and polyethylene terephthalate (PET) plastic waste into high-performance activated carbon for carbon dioxide (CO2) capture. This innovation addresses two critical environmental challenges simultaneously: reducing industrial CO2 emissions and managing large volumes of waste. The process involves co-pyrolysis of coffee and plastic waste at 600°C with potassium hydroxide (KOH) as an activating agent, producing a material with strong CO2 adsorption capacity suitable for industrial applications. This dual-purpose technology leverages abundant waste streams—over 10 billion kilograms of coffee waste and millions of tons of PET plastic produced annually—to create an economically viable and sustainable solution for carbon capture. The activated carbon produced can effectively adsorb CO2 from fossil fuel-based energy systems, helping mitigate air pollution and climate change.

Designer Odette Dierkx has conceptualized a futuristic fungi-based prosthetic called the "79th Organ," intended to filter and break down microplastics inside the human body. Drawing on research that certain mushrooms, such as Pleurotus ostreatus (oyster mushroom), can digest plastics, this living organ uses fungal mycelium to enzymatically degrade microplastics through bioremediation. The organ would extract microplastics from the bloodstream, breaking them into harmless components, effectively acting as a detox system for pollutants the body cannot naturally process. Dierkx envisions this innovation as a necessary adaptation by 2110, reflecting the growing severity of plastic pollution and its infiltration into human health. The 79th Organ is designed with a domed capsule shape featuring internal gills and attaches to the lower abdomen via suction. It includes a magnifying glass to observe microplastic processing and a contamination dial to alert users to pollution levels. Dierkx has imagined multiple versions tailored to

The article highlights how two engineers, Bilen Aküzüm and Lukas Hackl, co-founders of Aepnus Technology, identified a significant but overlooked bottleneck in the battery supply chain: the chemical waste generated during mineral processing. Specifically, lithium extraction and battery recycling plants produce large amounts of sodium sulfate waste while simultaneously importing costly reagents like caustic soda (sodium hydroxide) and sulfuric acid. This linear chemical use results in high operating expenses—up to 30-40% of costs—and environmental burdens due to waste disposal. Motivated by this paradox, the engineers developed an innovative electrolyzer system that converts waste sodium sulfate back into valuable reagents, effectively closing the loop on industrial chemistry. After five years of research, pilot projects, and material science advances, Aepnus Technology’s electrolyzer has demonstrated reliable, energy-efficient conversion of sodium sulfate into high-purity caustic soda and sulfuric acid without relying on rare catalysts.

A recent study by Coventry University reveals that disposable face masks used extensively during the COVID-19 pandemic are becoming significant sources of microplastic pollution. Even unused masks, when immersed in water, release microplastic particles—primarily polypropylene—along with other plastics like polyethylene, polyester, nylon, and PVC. Filtering facepiece masks emit three to four times more microplastics than standard surgical masks, with most particles smaller than 100 micrometres. These materials resist natural degradation, posing long-term environmental risks as they accumulate in ecosystems and potentially enter the food chain, threatening biodiversity and human health. The research also identified harmful chemical additives such as Bisphenol B leaching from masks, which can disrupt hormones and harm aquatic life.

Japanese greentech startup Monochrome Company Limited has introduced a new silver-colored building-integrated photovoltaic (BIPV) system designed to blend seamlessly with building exteriors. Unlike traditional solar panels that are mounted separately, these BIPV panels can be integrated into walls, windows, or roofs, serving both as functional building materials and power generators. The silver variant mimics aluminum with a light-dependent appearance, appealing to architects seeking aesthetic flexibility. The panels measure 6.2 feet by 1.25 feet, are lightweight at 2.7 pounds per square foot, and produce about 75 watts each, while the black version generates 110 watts. Although these BIPV panels are less efficient than conventional solar panels (which typically produce 300–400 watts), they offer superior aesthetics and seamless integration, making them ideal for new constructions or major renovations rather than retrofits. Both versions use durable, corrosion-resistant fluorine-coated galvalume steel and feature IP-68 rated junction boxes

MIT researchers from CSAIL and the Hasso Plattner Institute have developed SustainaPrint, a hybrid 3D printing system that significantly reduces plastic waste without compromising structural strength. The method uses simulations to identify stress-prone zones in a 3D model and selectively reinforces these areas with high-performance plastics, while printing the rest of the object with biodegradable or recycled filament. This targeted reinforcement approach cuts down plastic use and maintains durability, addressing the common trade-off between eco-friendliness and strength in 3D printing materials. In tests using Polymaker’s eco-friendly PolyTerra PLA and Ultimaker’s stronger PLA, SustainaPrint required only 20% reinforcement to regain up to 70% of the strength of fully reinforced prints. In some cases, the hybrid prints matched or even outperformed fully strong prints, demonstrating that strategic material mixing can enhance performance depending on geometry and load conditions.

Northwestern University chemists have developed an innovative nickel-based catalyst that efficiently converts mixed single-use polyolefin plastics—such as milk jugs, plastic wraps, and disposable utensils—into valuable oils, waxes, and lubricants at relatively low temperatures and pressures. This process bypasses the traditionally necessary and labor-intensive sorting step, addressing a major bottleneck in plastic recycling. Unlike existing methods that require high heat and expensive catalysts, this single-site nickel catalyst operates at temperatures 100 degrees lower and half the hydrogen pressure, using significantly less catalyst material while achieving tenfold greater activity. The catalyst selectively breaks down branched polyolefins, enabling a cleaner and more efficient chemical recycling that produces high-quality products suitable for upcycling. A notable and unexpected finding was the catalyst’s improved performance in the presence of polyvinyl chloride (PVC), a toxic polymer that typically inhibits recycling processes. Even with PVC constituting up to 25% of the plastic mix, the catalyst maintained and enhanced its activity,

The article from CleanTechnica highlights that the main barriers to scaling mass timber construction in Canada have shifted from technical feasibility to insurance costs and inconsistent building code adoption. While engineers have demonstrated that cross-laminated timber (CLT) can produce tall, strong, and safe buildings, insurers currently charge significantly higher premiums—often four to ten times those of concrete—due to limited historical claims data and perceived risks such as fire and water damage during construction. This elevated insurance cost undermines the financial viability of mass timber projects despite their advantages in speed and carbon reduction. Additionally, uneven adoption of the 2020 National Building Code provisions across provinces and municipalities creates regulatory uncertainty and delays, particularly because many jurisdictions still require case-by-case alternative solutions reviews rather than allowing prescriptive, repeatable approvals. To overcome these bottlenecks, the article advocates for normalizing mass timber through data-driven risk assessment and regulatory harmonization. Establishing a national data trust to aggregate claims, fire test results, and performance monitoring would

MIT researchers have developed a novel “self-assembling” electrolyte material for electric vehicle (EV) batteries that significantly simplifies recycling. Inspired by a Harry Potter scene where Dumbledore cleans a room with a flick of his wrist, the team designed a battery electrolyte that can quickly disassemble when exposed to a simple organic solvent. This allows the battery’s layers to separate naturally, enabling easier sorting and recycling of individual components. Unlike conventional batteries, which are difficult and costly to recycle due to complex and harsh chemical processes, this new approach embraces a “recycle-first” design philosophy, creating materials that prioritize recyclability from the outset. The electrolyte material is composed of aramid amphiphiles (AAs), molecules that self-assemble into durable nanoribbons mimicking the strong chemical structure of Kevlar, combined with polyethylene glycol (PEG) to conduct lithium ions. These nanoribbons form a solid-state electrolyte that is both tough and functional, facilitating lithium-ion transport between the battery’s cathode and

Researchers at Purdue University, supported by a $7 million grant from the U.S. National Science Foundation, are engineering novel enzymes to convert crops like corn and sugar, as well as agricultural waste, into recyclable bioplastics called polyhydroxyalkanoates (PHAs). These bioplastics aim to match the toughness and malleability of conventional petroleum-based plastics while being biodegradable and infinitely recyclable. By using domestically sourced feedstocks, the project also seeks to reduce reliance on imported petrochemicals and strengthen U.S. supply chains. The team is focusing on overcoming the limitations of PHAs, which historically have been fragile and unstable at high temperatures, restricting their use in consumer and medical products. The approach involves tuning the chemical structure of PHAs to enhance their strength and thermal stability through biocatalysis—using engineered enzymes to drive specific chemical reactions efficiently and sustainably. Collaborators from several universities are contributing expertise in enzyme selection, engineering via deep learning, functional testing, and commercialization potential.

Researchers at the University of Sharjah in the UAE have developed an innovative method to convert shrimp waste—specifically shells, heads, and guts—into activated carbon capable of capturing carbon dioxide (CO₂). This process addresses two major environmental challenges simultaneously: managing the vast amounts of seafood waste generated globally (up to eight million tons annually) and mitigating climate change by reducing greenhouse gas emissions. The shrimp waste, sourced from Souq Al Jubail in Sharjah and originally from Oman, undergoes a multi-step treatment involving pyrolysis to create biochar, followed by acid treatment, chemical activation, and ball milling to produce a highly effective and stable CO₂ adsorbent. Beyond carbon capture, the activated carbon derived from shrimp waste has versatile applications including air and water purification, solvent recovery, gold extraction, and certain medical uses. The researchers emphasize that this approach exemplifies a circular economy by transforming problematic waste into a valuable resource, enhancing resource efficiency and sustainability.

A US research team led by Hailong Chen at Georgia Tech has discovered that fast charging zinc-ion batteries actually strengthens them, contrary to the common belief that fast charging degrades battery life. Zinc-ion batteries, which are abundant, low cost, nonflammable, and environmentally safer than lithium-ion batteries, have been limited by the growth of dendrites—needle-like zinc deposits that cause short circuits and reduce battery performance. The study found that charging at higher currents suppresses dendrite formation, resulting in smooth, densely packed zinc layers that enhance battery longevity and safety. The researchers developed a novel tool to observe zinc behavior under various charging rates in real time, enabling them to identify why fast charging prevents dendrite growth. While this breakthrough addresses the anode side of the battery, efforts are ongoing to improve the cathode and overall battery durability, including experimenting with zinc blends. This advancement could significantly impact energy storage solutions, making zinc-ion batteries viable for applications like home solar energy storage and grid stabilization, offering

Scientists at the MEET Battery Research Center and the University of Münster have developed an innovative recycling method for dry-processed lithium-ion battery cathodes, advancing sustainable and circular battery production. Unlike traditional wet processing, which uses solvent-based slurries, dry processing employs polytetrafluoroethylene (PTFE) as a binder, eliminating costly and toxic solvents. The new recycling technique leverages mild mechanical milling to delaminate and recover cathode materials from aluminum current collectors without harsh chemicals or high heat, preserving the integrity of active materials and the PTFE binder network for direct reuse in battery manufacturing. This approach not only supports greener battery production but also proves economically viable. Tests demonstrated that electrodes made from recycled materials perform comparably to those from new composites. A life-cycle cost assessment indicated that even at a low scrap rate of 5%, the method reduces electrode processing costs by about 2.6% (approximately USD 0.8 per kWh) and lowers carbon emissions by around 2

Researchers at King’s College London have developed a novel keratin-based toothpaste derived from human hair protein that could repair tooth enamel, reduce sensitivity, and prevent decay. Unlike enamel, which cannot regenerate naturally, keratin forms a protective, enamel-like coating by interacting with minerals in saliva, creating a dense mineral layer that halts decay and seals exposed nerve channels. This biomimetic approach offers both structural protection and symptomatic relief, potentially reducing the need for fillings or crowns in early-stage tooth damage. The keratin used in the toothpaste is sustainably sourced from biological waste such as hair and wool, providing an eco-friendly alternative to traditional toxic plastic resins used in restorative dentistry. The protein forms a crystal-like scaffold on the tooth surface that attracts calcium and phosphate ions, gradually rebuilding enamel with a natural color match that improves aesthetics and patient satisfaction. The researchers anticipate that keratin-based enamel regeneration products could be available within two to three years, delivered either as daily toothpaste or professionally applied gels, marking a significant advancement in

The article explores the challenges and limitations of plastic recycling, emphasizing that the issue extends beyond consumer behavior to fundamental thermodynamic, chemical, and engineering constraints. Since the invention of the first man-made plastic, Parkesine, in 1862, plastics have evolved into a diverse range of durable materials that have become ubiquitous in daily life. However, by the late 1960s, scientists began detecting widespread plastic pollution in the environment, prompting the adoption of recycling as a solution. Although recycling initially appeared promising by reducing waste and conserving resources, it has revealed significant drawbacks over time, including high costs, inefficiencies, toxicity concerns, and the release of microplastics. The article details the three main recycling methods: mechanical, chemical, and energy recycling. Mechanical recycling, the most common commercial method, involves collecting, sorting, washing, and reprocessing plastics like PET and HDPE but is limited by contamination and material degradation.

Scientists at Stanford, inspired by ancient Roman observations, have developed a new type of cement made from volcanic rock that requires no kiln and produces significantly less carbon dioxide. The research draws on Pliny the Elder’s account from 79 A.D., describing how volcanic ash from the Puteoli region (modern Pozzuoli) naturally hardens into stone when immersed in water—a property that contributed to the durability of Roman structures like the Pantheon. Traditional cement production involves heating limestone above 1,400°C, releasing about 8% of global CO₂ emissions, making it a major contributor to climate change. Tiziana Vanorio and her team studied volcanic rocks beneath the Campi Flegrei supervolcano near Pozzuoli, which had naturally undergone heating and lost carbonate content, thus avoiding CO₂ release during processing.

SY Zero is the world’s first fossil-free sailing superyacht, nearing completion with a planned launch at the end of 2025. Measuring nearly 70 meters, the yacht is the product of over 60,000 hours of research and development by Vripack Yacht Design, Vitters Shipyard, and other collaborators. It is powered entirely by renewable energy sources—wind, solar, and thermal—eliminating the need for fossil fuels. A key feature is its five megawatt-hour energy storage system, comparable in capacity to 88 Tesla vehicles, which powers all onboard functions including propulsion, lighting, and utilities. The yacht collects energy through innovative methods such as hydro-generating thrusters that harness water flow while sailing, a 100-square-meter hybrid solar panel array with 60% efficiency, and a wind turbine utilizing offshore airflow. The project aims to demonstrate that high standards of comfort, design, and performance can be achieved without fossil fuels, serving as a model for sustainable naval

Researchers from the University of Washington and Microsoft have developed a low-carbon concrete by incorporating powdered green seaweed into cement, achieving a 21 percent reduction in global warming potential without compromising structural strength. Cement production is a major contributor to global CO₂ emissions, responsible for about 10 percent of the total, primarily due to fossil fuel use and the calcination process. Seaweed, as a photosynthetic organism, acts as a carbon sink during growth and can be used in dried, powdered form without expensive processing, making it a promising sustainable additive for cement. To accelerate the traditionally slow trial-and-error process of optimizing concrete mixtures, the team employed a custom machine learning model that predicted the best seaweed-cement blends. This approach reduced the development time from an estimated five years to just 28 days. The researchers envision using this method to tailor cement formulations to local resources and conditions, potentially incorporating other bio-based materials like different algae species or food waste.

Japanese researchers from Yokohama National University, Electric Power Development Co., Ltd., and Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have developed a novel method to convert carbon dioxide (CO2) from thermal power plant exhaust directly into valuable organic chemicals using recycled silicon wafers from discarded solar panels. By pretreating crushed solar panel silicon wafers with hydrochloric acid to remove aluminum contaminants, the team enhanced the wafers’ ability to act as reducing agents in the reaction. The process involves combining the untreated exhaust gas (containing about 14% CO2) with water, a catalyst (tetrabutylammonium fluoride), and the recycled silicon powder, resulting in the efficient production of formic acid and formamide without the need for CO2 purification. This breakthrough offers a dual environmental benefit: it repurposes waste silicon from obsolete solar panels—addressing the growing issue of photovoltaic panel disposal predicted to reach tens of millions of metric tons by 2050

A two-year field trial conducted on Sydney Trains’ Chullora freight corridor has demonstrated that a recycled rubber track underlay significantly reduces ballast degradation and maintains track stability under heavy loading. Developed and patented by University of Technology Sydney (UTS) researchers, the system uses tyre-derived rubber “cells” filled with waste materials and covered by recycled rubber grids made from worn mining conveyor belts. Compared to conventional track sections, the rubber-reinforced areas showed markedly less ballast pulverization and slower track settlement, as documented in a peer-reviewed study published in the Canadian Geotechnical Journal. This innovation effectively protects the ballast by absorbing shocks and spreading axle loads more evenly, thereby extending the life of the track structure and reducing maintenance needs such as tamping. The recycled rubber underlay changes the traditional load path by compressing elastically under train wheels, which lowers peak stresses on ballast stones and distributes forces over a wider area of the underlying soil. This prevents soil settlement and weakening of the track foundation, critical for

Researchers at Worcester Polytechnic Institute (WPI) have developed an environmentally friendly and scalable hydrometallurgical recycling method for lithium-ion batteries, recovering 92 percent of critical metals such as nickel, cobalt, and manganese. This approach converts spent nickel-lean cathode materials into high-quality cathode powder suitable for reuse in batteries. Batteries made from this recycled cathode powder retained 88 percent of their capacity after 500 charge cycles and over 85 percent after 900 cycles, demonstrating strong performance and longevity. The new method is also energy-efficient, consuming 8.6 percent less energy and reducing carbon emissions by 13.9 percent compared to conventional recycling techniques. This innovation addresses the environmental challenges posed by battery waste and reduces reliance on environmentally damaging mining activities. The research, led by Professor Yan Wang, highlights the potential for creating high-performance batteries from recycled materials at scale, contributing to a more sustainable and resilient battery supply chain essential for supporting renewable energy infrastructure.

Researchers at Graz University of Technology (TU Graz) in Austria have developed an innovative electric vehicle (EV) battery enclosure that combines thin sheet steel filled with wood, offering a safer and more sustainable alternative to the aluminum cases used by Tesla. Led by Florian Feist, the team created this hybrid structure as part of the Bio!Lib project, aiming to reduce the environmental impact of battery production while enhancing crash safety. The wood core’s cellular structure absorbs energy during crashes, and the steel-wood composite underbody and lid, reinforced with rib-like cross struts, demonstrated crash performance comparable to Tesla’s Model S aluminum battery case in pole crash tests. To improve fire resistance, the researchers incorporated cork as an insulating layer, which chars under extreme heat, reducing thermal conductivity and protecting the vehicle’s interior.

Researchers at Binghamton University, led by PhD student Tianzheng Liu and supported by Professors Sha Jin and Kaiming Ye, have developed an innovative microbial process that converts food waste into biodegradable plastic and organic fertilizer. Using the bacteria Cupriavidus necator, which synthesizes polyhydroxyalkanoate (PHA) from fermented food waste containing lactic acid and ammonium sulfate, the team can harvest about 90% of the bioplastic produced. This method addresses two major environmental issues simultaneously: the massive food waste in landfills that emits greenhouse gases and the growing problem of plastic pollution. The process is robust and adaptable, working with various types of food waste as long as the mixture ratios remain consistent, and the waste can be stored for at least a week without impacting results. The leftover residue from fermentation is also being evaluated as an organic fertilizer alternative to chemical fertilizers. The researchers aim to scale up the system for industrial application, seeking partnerships and additional funding to expand the

Researchers at EPFL and Kyoto University have developed the first hydride-based deep eutectic solvent (DES), a hydrogen-rich liquid stable at room temperature that could revolutionize hydrogen storage. This liquid is created by mixing ammonia borane and tetrabutylammonium borohydride in specific ratios (50%-80% ammonia borane), resulting in a transparent, stable liquid containing up to 6.9% hydrogen by weight—surpassing the US Department of Energy’s 2025 hydrogen storage target. The DES remains liquid due to strong hydrogen bonding disrupting the crystalline structure of the individual components, and it does not crystallize even when cooled below −50°C, instead undergoing a glass transition. This new hydrogen storage medium offers significant advantages over existing methods, which rely on high-pressure gas compression or cryogenic cooling, both energy-intensive and cumbersome. The liquid releases pure hydrogen gas at a relatively low temperature of 60°C, requiring less energy than many solid-state storage materials, and only the

The article highlights an innovative approach to reducing pollution from maritime shipping, a sector responsible for about 3% of global carbon emissions. London-based company Seabound has developed a retrofit technology that captures carbon dioxide emissions from a ship’s existing internal combustion engines and converts the CO2 into limestone, a key ingredient in cement. This system is currently installed on the UBC Cork, a cement carrier sailing in the Mediterranean. The limestone produced during the voyage will be offloaded in Norway and used at Heidelberg Materials’ net-zero cement plant in Brevik, thereby closing a carbon loop between shipping and cement production—two industries that together contribute roughly 11% of global emissions. The technology offers a practical alternative to other decarbonization methods like batteries or ammonia fuel, which either lack sufficient energy density for long voyages or require extensive engine overhauls. Seabound’s retrofit allows ships to maintain their existing engines while capturing emissions directly from exhaust pipes. This innovation aligns with the International Maritime Organization’s (IMO

A collaborative team of scientists from multiple U.S. Department of Energy national laboratories, led by the National Renewable Energy Laboratory (NREL), has uncovered how light activates nickel-based catalysts to drive chemical reactions while preserving their reactivity. Published in Nature Communications, the research reveals that exposure to light breaks a bond in nickel dihalide catalysts, lowering nickel’s oxidation state and making it reactive. Crucially, the freed halide ion (chlorine radical) interacts with the solvent to form a previously unknown, stable nickel intermediate. This intermediate prevents the reactive nickel atoms from binding to each other and deactivating, thereby maintaining the catalyst’s activity. This discovery advances understanding of light-driven nickel catalysis, which offers advantages over traditional palladium catalysts, including lower cost, milder reaction conditions, and the ability to facilitate novel chemical transformations. Nickel is significantly cheaper than palladium—about 50 cents per ounce versus nearly $1,000 per ounce for palladium—and can be activated by light rather than heat

Researchers at Chung-Ang University in South Korea have developed a novel air filtration system inspired by the mucus layer in the human nose, which naturally traps dust, allergens, and harmful particles. This bioinspired filter, called the particle-removing oil-coated filter (PRO), uses a thin, stable film of biocompatible oil (200 to 500 nanometers thick) applied to standard filter fibers. This coating mimics the sticky mucus barrier and enhances particle capture through capillary adhesion, significantly improving retention compared to conventional filters that rely on weaker van der Waals forces. Field tests conducted in various indoor environments in Seoul, including offices, exhibition centers, and stadiums, demonstrated that the PRO filter not only traps more airborne pollutants but also lasts twice as long as traditional filters. Additionally, its sticky oil layer prevents particles from being dislodged by strong winds, making it suitable for high-airflow locations such as construction sites and metro stations. The filter is compatible with existing HVAC and air purifier systems

New Zealand-based Aspiring Materials has developed a patented chemical process that extracts valuable battery metals—specifically nickel-manganese-cobalt (NMC) hydroxide—from the mineral olivine without generating waste or carbon dioxide emissions. This innovation addresses the traditionally low economic value of olivine by transforming it into critical materials used in lithium-ion batteries for electric vehicles and energy storage, while also supporting industrial decarbonization efforts. The process yields multiple products: about 50% silica, usable as a partial substitute for Portland cement; roughly 40% magnesium products applicable in carbon sequestration and wastewater treatment; and the remaining 10% comprising iron combined with NMC hydroxide. Beyond carbon capture, this approach enables broader utilization of olivine-derived minerals, potentially reducing reliance on international supply chains for critical battery metals.

Researchers have developed a lignin-based film separator derived from wood that significantly enhances the safety and longevity of lithium-ion batteries (LIBs), particularly for electric vehicles (EVs) and portable electronics. This wood-based separator remains dimensionally stable at temperatures up to 300°C (572°F), outperforming conventional polyethylene and polypropylene separators that suffer from thermal shrinkage and instability. The lignin film prevents internal short circuits and thermal runaway, reducing fire risks, while also extending battery cycle life by 60%, meaning the battery can be charged and discharged many more times before degrading. The lignin separator is produced using a solvent-free dry process, which is environmentally friendly and scalable, generating no waste or emissions. Made from lignosulfonate—a natural polymer byproduct of pulping and biorefinery—the film is thin (about 25 micrometers) yet effective at maintaining battery stability. This sustainable manufacturing approach not only reduces environmental impact but also leverages abundant natural materials without additional processing. Overall

A recent study from Brandon University, led by Dr. Bryan Cassone, reveals that waxworms—the caterpillars of the greater wax moth—can rapidly degrade polyethylene, the most common plastic worldwide. Remarkably, about 2,000 waxworms can consume an entire polyethylene bag within 24 hours, a process that normally takes decades or centuries in the environment. The research shows that waxworms metabolize the plastic into lipids stored as body fat, similar to how humans store fat from food. However, an all-plastic diet is lethal to the caterpillars, causing mass loss and death within days. Cassone suggests that co-supplementing their diet with other food sources could sustain and even enhance their health, enabling mass rearing. The implications of this discovery are twofold: waxworms could be farmed on a supplemented polyethylene diet to help reduce plastic waste as part of a circular economy, or scientists could isolate and replicate the enzymes responsible for plastic degradation in laboratory or industrial settings

A recent international study led by Kiel University highlights the potential of lithium-sulfur batteries (LSBs) to revolutionize electric vehicle (EV) charging by enabling full charges in as little as 12 minutes, significantly faster than current lithium-ion batteries that typically require 20 to 30 minutes for partial charges and longer for full ones. LSBs offer a theoretical energy density of up to 2,600 watt-hours per kilogram—nearly ten times that of conventional lithium-ion cells—due to their sulfur cathode paired with a metallic lithium anode. This could translate to much longer driving ranges and help alleviate range anxiety, a major barrier to EV adoption. Additionally, sulfur is abundant, eco-friendly, and cost-effective compared to cobalt and nickel used in lithium-ion batteries. Despite these advantages, LSB technology faces several challenges. Sulfur’s poor electrical conductivity requires mixing with carbon-based materials, which adds weight and complexity. The sulfur cathode also undergoes significant volumetric changes during charging cycles

Researchers at the University of Tokyo have developed a novel synthetic polymer inspired by the natural loofah sponge, featuring a porous, loofah-like structure that is stronger than typical plastics yet lighter than foam. This innovative material exhibits remarkable mechanical properties, achieving a stiffness of up to 11 gigapascals at a low density of 0.5 grams per cubic centimeter—about four times stronger than conventional polymers. The polymer is pH-responsive, becoming more rigid or flexible depending on acidity, and its fine pore network (around 70 nm) allows fluids to pass while filtering and killing bacteria and viruses, making it highly suitable for filtration, structural applications, and potentially medical devices. The polymer is synthesized simply using water, applied voltage, and a mixture of resorcinol and an aldehyde, producing an ultrathin porous membrane without requiring post-processing.

Researchers at Harvard’s John A. Paulson School of Engineering and Applied Sciences have successfully grown green algae (Dunaliella tertiolecta) inside bioplastic pods designed to simulate Mars-like conditions. The team recreated Mars’ thin atmosphere, with pressure over 100 times lower than Earth’s, and used 3D-printed chambers made from polylactic acid bioplastic. These chambers effectively blocked harmful UV radiation while allowing enough light for photosynthesis. Despite the low atmospheric pressure that typically prevents liquid water from existing, the pods maintained a pressure gradient stabilizing water, enabling algae survival in a harsh, carbon dioxide-rich environment. This breakthrough suggests the potential for creating self-sustaining, closed-loop habitats on Mars, where bioplastic shelters could grow algae that in turn produce more bioplastic, enabling habitats to maintain and expand themselves over time. This biomaterial approach contrasts with traditional, resource-intensive construction methods by mimicking natural growth processes. Combined with previous innovations like silica aerogels to address

Key innovations in the process include optimized reaction conditions and separation technologies that drastically reduce the need for costly acid and base additives by over 99%, cut annual operating costs by 74%, and lower energy consumption by 65%.

Australian researchers at Swinburne University of Technology, led by Dr. Yat Wong, have developed sustainable bricks made from spent coffee grounds (SCGs), offering a significant reduction in construction-related carbon emissions. By blending coffee waste with clay and an alkali activator, these bricks can be fired at just 200°C—about 80% lower than traditional brick firing temperatures—resulting in up to an 80% reduction in electricity-related CO₂ emissions per unit. This innovation not only diverts large quantities of coffee waste from landfills, thereby reducing methane emissions, but also produces bricks that exceed Australian minimum strength standards, making them both environmentally friendly and durable. Globally, around nine million tonnes of ground coffee are consumed annually, generating approximately 18 million tonnes of wet SCGs, much of which ends up in landfills contributing to greenhouse gas emissions. In Australia alone, over 1.3 million cups of coffee are sold daily, producing about 10,000 tonnes of coffee

Yale scientists, in collaboration with New Haven ceramic artist Kiara Matos, have developed a sustainable ceramic glaze made from eggshell waste, addressing the global issue of approximately 80 million metric tons of eggshells discarded annually. Eggshells, which are about 95% calcium carbonate, were processed by burning at 800°F to remove organic material, then ground into a fine powder to create ceramic glazes. These eggshell-based glazes were tested against traditional glazes made from mined calcium carbonate and found to have comparable, if not superior, qualities in appearance, durability, and resistance to wear and dishwasher cycles. The eggshell glaze demonstrated a smoother texture and vibrant color, prompting Matos to transition her pottery business entirely to this sustainable material. This innovation not only offers a practical reuse for eggshell waste—which can be hazardous and malodorous if untreated—but also promotes environmental sustainability by replacing mined materials with a renewable waste product.

These compounds are then fed into a second catalytic loop where they are converted into polyketones—high-strength plastics valued for their durability and thermal stability, commonly used in adhesives, automotive parts, sports equipment, and industrial piping. Unlike previous methods relying on fossil-derived ethylene, this process uses sustainably sourced CO₂, water, and electricity, potentially reducing emissions and dependence on petroleum-based feedstocks. The system operates via two separate loops optimized for different reaction conditions. The first loop uses gas diffusion electrode cells with copper-coated hydrophobic polymers to electrochemically reduce CO₂ into ethylene and carbon monoxide at relatively high concentrations (11% and 14%, respectively).

This new approach uses a low-cost, environmentally benign compound called trichloroisocyanuric acid—commonly used in water treatment—that, when activated by saltwater, dissolves gold effectively. The dissolved gold is then selectively captured by a specially designed sulfur-rich polymer, which is synthesized using a sustainable UV light-initiated process. Importantly, the polymer can be recycled after gold recovery, enhancing the method’s environmental credentials and reducing waste. This technique addresses the significant environmental and health hazards posed by traditional gold extraction methods that rely on toxic chemicals like cyanide and mercury. By providing a safer alternative, especially for small-scale mining operations that often use mercury, the new method has the potential to reduce mercury pollution globally.

The National Renewable Energy Laboratory (NREL) has developed a novel, scalable, and cost-effective method to recycle all components of carbon fiber composites (CFCs), materials widely used in high-value products like aircraft, bicycles, and automobiles. CFCs consist of carbon fibers embedded in epoxy-amine resins, which are strong, lightweight, and expensive, but difficult to recycle due to the chemically interlocked and complex nature of the resin. Traditional recycling methods have been limited by the inability to dissolve or break down these resins without degrading the valuable fibers or wasting the resin’s chemical components. NREL’s breakthrough involves using hot acetic acid—essentially vinegar—to cleave the key bonds in the epoxy resins, solubilizing the polymer networks while preserving the chemical building blocks for reuse. This method was optimized to handle diverse resin formulations from various industries and was shown to recover carbon fibers without compromising their strength.

This featherlight material, made from calcium-intercalated graphene oxide aerogel, can absorb over three times its own weight in water. The material leverages enhanced hydrogen bonding created by combining calcium ions with graphene oxide, resulting in a synergistic effect that significantly boosts water adsorption beyond the sum of its individual components.

Researchers led by Dr. Chi Zhou at the University at Buffalo have developed a sustainable thermal insulation material by 3D-printing fibers derived from wheat straw, an agricultural byproduct typically burned after harvest. Wheat straw’s natural fibrous and porous structure provides effective thermal insulation, high mechanical strength, and enhanced flame retardancy compared to other organic materials. The process involves pulping wheat straw into a slurry, drying it into a thick ink, and cross-linking the fibers with an organic binder to ensure material integrity before 3D printing. This innovation offers a renewable, biodegradable alternative to conventional insulation materials like glass and rock wool, which rely heavily on fossil fuels and contribute to greenhouse gas emissions. To address the slow printing speed of early methods, Zhou’s team redesigned the 3D printer with a slot-die nozzle and multiple nozzles for faster, more uniform material deposition, making the process scalable for industrial production. Using wheat straw not only reduces environmental impact by lowering emissions and decreasing agricultural waste but

Researchers at the Paul Scherrer Institute (PSI) have developed an AI-driven approach to design low-carbon cement recipes up to 1,000 times faster than traditional methods. Cement production is a major source of CO₂ emissions, primarily due to the chemical release of CO₂ from limestone during clinker formation. To address this, the PSI team, led by mathematician Romana Boiger, combined thermodynamic modeling software (GEMS) with experimental data to train a neural network that rapidly predicts the mineral composition and mechanical properties of various cement formulations. This AI model enables quick simulation and optimization of cement recipes that reduce carbon emissions while maintaining strength and quality. Beyond speeding up calculations, the researchers employed genetic algorithms to identify optimal cement compositions that balance CO₂ reduction with practical production feasibility. While these AI-designed formulations show promise, extensive laboratory testing and validation remain necessary before widespread adoption. This study serves as a proof of concept, demonstrating that AI can revolutionize the search for sustainable building materials by efficiently navigating complex chemical

Scientists from the University of California, Irvine, in collaboration with U.S. and Japanese researchers, have developed a synthetic yeast system that converts human urine into hydroxyapatite (HAp), a biocompatible calcium phosphate mineral widely used in bone and dental implants. This innovative process addresses two significant challenges simultaneously: it helps mitigate environmental pollution caused by excess nutrients in wastewater and produces a valuable medical material projected to reach a $3.5 billion market by 2030. The engineered yeast, dubbed “osteoyeast,” mimics natural bone-forming cells by breaking down urea to increase pH, facilitating the crystallization and secretion of HAp outside the cell, yielding up to 1 gram per liter of urine. The process is scalable, cost-effective, and accessible globally, as it uses yeast fermentation techniques similar to those in beer production, requiring relatively low temperatures and minimal infrastructure. This makes it particularly suitable for deployment in developing regions lacking advanced manufacturing capabilities, potentially broadening access to advanced

The article highlights the inherent fire risks associated with wood pellet mills, which produce highly flammable compressed wood products used for heating and grilling. Since 2010, at least 52 fires have occurred at such facilities across the US, with many of the largest mills experiencing fires or explosions. The biomass company Drax, a major player in the industry, has a history of fire-related incidents at its facilities in the UK and Louisiana. Despite these safety concerns and ongoing lawsuits, Drax is moving forward with plans to build two new pellet mills in California, through its partner Golden State Natural Resources (GSNR), claiming that their operations will help mitigate wildfire risks by utilizing dead or dying trees from nearby forests. The proposed mills in Tuolumne and Lassen counties, both forested and wildfire-prone areas, have sparked opposition from local residents and experts who question the safety and environmental impact of manufacturing wood pellets in these regions. Concerns include inadequate communication with nearby communities, potential overharvesting of biomass by

MIT scientists have developed an innovative, origami-inspired hydrogel device that passively harvests clean drinking water from atmospheric moisture without requiring any external power source. The black, window-sized panel, made from a water-absorbent hydrogel enclosed in a glass chamber with a cooling polymer coating, exploits natural temperature fluctuations between night and day to absorb and then release water vapor. Tested in California’s Death Valley, one of the driest places on Earth, the prototype successfully extracted up to 160 milliliters of water daily even at low humidity levels (around 21%), demonstrating its effectiveness in arid environments. The hydrogel’s unique composition, stabilized with glycerol to prevent salt leakage, ensures the collected water remains safe to drink without the need for additional filtration. Its dome-shaped, bubble wrap–like surface design increases absorption efficiency by maximizing surface area. Unlike previous technologies that depend on electricity, batteries, or solar panels, this device operates autonomously, making it particularly suitable for resource-limited

Researchers at the University of Michigan, led by chemist Charles McCrory, have developed a novel method to capture carbon dioxide (CO₂) from the air and convert it into metal oxalates, stable solid compounds that can serve as precursors for cement production. This approach aims to transform CO₂, typically viewed as a waste product, into valuable building materials, potentially reducing the carbon footprint of construction. The work is part of efforts by the Center for Closing the Carbon Cycle (4C), funded by the U.S. Department of Energy, which focuses on converting captured carbon into useful fuels and industrial products. The team’s innovation centers on using trace amounts of lead as a catalyst to convert CO₂ into metal oxalates via electrochemical reactions. By employing specially designed polymers, they reduced the lead catalyst to parts per billion—levels comparable to natural impurities—addressing previous environmental and health concerns associated with higher lead usage. In the process, CO₂ is electrochemically transformed into oxalate ions, which then combine with metal ions released from an electrode to form solid metal oxalates. These solids are stable and do not revert to CO₂ under normal conditions, making them promising for cleaner cement production. While electrolysis of CO₂ is already being scaled up industrially, the researchers note that further work is needed to scale the metal oxalate production step, but they remain optimistic about its feasibility. This breakthrough offers a potential pathway to reduce the environmental impact of traditional Portland cement manufacturing, which is energy-intensive and a major source of global carbon emissions. By turning pollution into building blocks, the research opens new avenues for sustainable construction materials and carbon capture utilization. The study detailing these findings was published in the journal Advanced Energy.

The article highlights the urgent call by the United Nations Environment Program (UNEP) for global action to #BeatPlasticPollution, the theme of World Environment Day 2025. It emphasizes the critical importance of addressing the full lifecycle of plastics—from production to disposal—rather than relying solely on recycling. With over 460 million tons of plastic produced annually, plastics and microplastics have become pervasive pollutants, infiltrating terrestrial and marine ecosystems, soils, the atmosphere, and even human bodies, including lungs, blood, and fetuses. This widespread contamination poses serious threats to human health, planetary ecosystems, and economic stability. The article also notes that plastics contribute significantly to carbon emissions and are filling oceans, harming marine life and coastal communities. South Korea, the 2025 World Environment Day host, is identified as the fourth largest producer of plastic polymers globally, underscoring the challenge of plastic pollution even among environmentally engaged nations. The article draws attention to the prevalence of polyethylene terephthalate (PET) plastics, which constitute about 50% of microplastics in wastewater and 12% of global solid waste, highlighting ongoing research into biodegradation methods. Looking ahead, plastic production is projected to triple by 2060 unless decisive global measures are taken. A key upcoming event is the August 2025 vote in Geneva on a global plastics treaty aimed at banning certain plastics, though progress faces resistance from petrochemical-producing countries. Advocates stress the need to “turn off the plastics tap” and implement systemic changes to reduce plastic pollution worldwide.
