QS Biodiesel Limited is a privately-held, biodiesel technology company with offices in London and Budapest. QSB has developed a more efficient, lower-cost biodiesel production process applicable
to both new and existing biodiesel plants.
Based on ten years of research by Dr Andras Kovacs, QSB has learned how to apply petrochemical manufacturing processes to biodiesel production leading to significant improvements in performance and reductions in resources required. Using a proprietary co-solvent-based approach, the technology allows the production of high-quality biodiesel in a single-step continuous reaction from oil and grease feedstocks of varying quality levels. Lower energy requirements and small inventories translate into lower capital and operating costs.
QSB has a pilot plant operating in Budapest, Hungary.
