Frying fat: very high in energy
Frying fats and oils are collected in the Netherlands and beyond by high volume users and supermarkets. They are then collected by companies that specialise in gathering these fats and oils. Sunoil Biodiesel maintains direct contact with these companies.
The fact that frying fat consists mainly of saturated esters and fatty acids means that it is very high in energy. Once it has been filtered frying fat can be used as the main constituent of biodiesel.
