Biodiesel is an environment-friendly fuel with clear and substantial advantages over conventional diesel, but even at full production it could only ever meet around 8% of the demands of the global diesel market. Currently, 95% of the world biodiesel is produced from high-grade feedstock such as rapeseed, sunflower oil, and soybean oil (all high-grade feedstocks). This has led to major environmental problems such as serious destruction of vital soil resources, deforestation and large usage of the available arable land. The negative effects of high-grade feedstock use in biodiesel production resulted in their exclusion from REDII – the proposed new EU mandate that caps high-grade feedstock biodiesel blending at 3.8% by 2030. In order to meet REDII’s minimum 6.8% blend from alternative feedstocks, the industry needs to produces biofuel such as biodiesel from second grade feedstocks, which has technical issues using current production methods.
TransBiodiesel Ltd. has patented TransZyme A, an immobilized enzyme technology for the production of biodiesel using any grade feedstocks (FFAs 0– 100%). Its main features are its tolerance to high concentrations of methanol and water and its long-term operational lifetime, which makes its use economically viable for biodiesel production. This innovative enzyme uses a unique continuous production method, which is more cost effective than current chemical production methods.
