Biodiesel is a clean low carbon transport fuel that can be used as a substitute for fossil diesel or blended with fossil diesel in diesel engines.

Approximately 90% of global biodiesel production is based on virgin oils produced from crops such as rapeseed, soy and palm. Biodiesel from virgin oils is controversial because it competes with the use of the oils for food, is believed to have been a contributor to food price rises, and can cause indirect land use change which calls into question its environmental benefit.

Biodiesel produced from waste is free of these controversies and results in significantly better (65% – 80%) greenhouse gas emissions reductions because it avoids the upstream carbon emissions associated with crop production and seed oil extraction.
