The global pursuit for the more sustainable world encourages research projects to focus on finding methods of production that are characterized by the use of renewable or recycled sources, low carbon footprint and restricted amounts of synthetic and toxic reagents involved. The aim of this research is to use a post-consumed rapeseed oil as a renewable feedstock in the epoxidation process. Vegetable oil is easily convertible intermediates and have a wide commercial use because of their varied chemical activity. Epoxides have been used as raw materials for products such as alcohols, glycols, plasticizers, high-temperature lubricants, polyols and polymers e.g., polyurethane, polyesters and epoxy resins Developed enzymatic epoxidation process allowed to remove small molecular weight acids that are used as an oxygen carrier in the state of art methods.
