New tech upcycles biodiesel waste into $78B industrial solvent

Scientists at Loughborough University spin-out R3V Tech have developed an innovative electrochemical process that converts crude glycerol, a low-value by-product of biodiesel production, directly into solketal—a high-value bio-derived solvent used in pharmaceuticals, cosmetics, and as a fuel additive. This technology operates at room temperature and atmospheric pressure, significantly reducing energy consumption and emissions compared to traditional energy-intensive refining methods. By enabling on-site conversion, the process eliminates costly transport and waste, while also utilizing waste carbon dioxide to further lower the carbon footprint of biodiesel production. The global market for solketal is estimated at $78 billion, presenting a substantial new revenue opportunity for biodiesel producers who currently pay to dispose of crude glycerol. R3V Tech’s modular, plug-in system aims to allow producers to refine their waste easily and sustainably, creating a circular, low-carbon economy.
