Benefits of biodiesel from waste FOG
Apart from preventing the risks and costs associated with waste greases entering the sewage system, biodiesel made from reclaimed oils has several advantages over first generation fuels made from virgin oils:
- Biodiesel produced from waste greases produces 7 times more energy than is put into the process.
- Results in an 86% reduction in life cycle carbon emissions compared to petrodiesel. This is a significant improvement from first generation biodiesel, which provides a life cycle emissions reduction of 54%.
- Does not impact upon food crop prices or use extra farm land thereby avoiding the negative externalities of first-generation biofuels.
- Feedstock costs make up 70 - 80% of the total production costs for conventional biodiesel, whereas waste greases are much cheaper.
