Renewable fuel produced by a chemical reaction (trans-esterification) using animal oils, waste cooking oils and alcohol in the presence of a catalyst. Fertiliser and glycerine are produced as by products
Biodiesel can be manufactured from a large number of different feedstocks.
Biodiesel is as efficient as fossil diesel in powering unmodified diesel engines.
There are no process wastes, catalyst is recovered as a fertiliser. Water and methanol used in the process are recovered and recycled.
