On June 2020, the LIFE Superbiodiesel project (Production of advanced biodiesel from animal wastes using supercritical technologies) started. The objective of this project is to demonstrate on a pilot scale a new technology for the transesterification of fats with methanol under supercritical conditions using new heterogeneous catalysts. The process allows greater flexibility in terms of the acidity of the source fats, the reduction or elimination of glycerine by-products, the reduction of the carbon footprint well above the objectives of the Renewable Energy Directive, and the reduction of polluted effluents from the process.
