BioDiesel from waste materials

Company: BDI – BioEnergy International AG

Location: Stanlow, GB


BioDiesel is now an integral part of the supply of the transport sector with renewable energy. Many drivers are unaware that there are already around 7% of a fuel filling of biogenic fuel in the EU today. In order to reduce global CO2 emissions and keep climate warming, according to current EU Commission plans, this share will continue to rise. The use of local waste materials on the one hand promotes the safe utilization of fat-containing waste streams as well as the associated energy self-sufficiency.

The Styrian plant manufacturer BDI has been successfully demonstrating for years that the production of sustainable and climate-friendly BioDiesel is possible without the use of vegetable oils from the food industry (for example rape oil, palm oil, etc.). The "Multi-Feedstock" BioDiesel plant, commissioned in 2017 in Stanlow, England, after a project period of two years, processes the most difficult waste - the so-called "Fettberg" is used for

biodiesel production. These are tonnage-heavy lumps, which are gathered from oil, grease and waste in the wastewater sewers of cities and then have to be removed and disposed of with enormous effort.=> Turning fat into green fuel (Quelle BBC)

This fat content, which has a high percentage of free fatty acids (FFA), can be converted into standard, high-quality biodiesel (EN14214) of the second generation in several process steps using the latest technology. Every year, up to 85 million liters of BioDiesel can be produced in Stanlow from grease separator grease, old cooking oil, animal fat, technical fatty acids and many other waste materials, which causes 86% less greenhouse gases than mineral diesel. This innovative BDI technology can also be used in existing large-scale plants. The BDI RetroFit program can be used to refine and optimize these to improve the raw material flexibility and improve the quality of BioDiesel.
