Biodiesel is the common name for a group of compounds called esters that are manufactured from a variety of vegetable oils or animal fats using a relatively simple chemical reaction called transesterification.
The biodiesel component of Biogold™ biodiesel is made from used cooking oil and oilseed rape, grown specifically for Biogold™ biodiesel production,
Biogold™ biodiesel is only made from canola-based vegetable oils, including a proportion of locally-grown virgin canola oil. This, combined with our careful screening and testing of used cooking oil, means Biogold™ biodiesel meets the exacting European biofuel standards, a step up from the New Zealand Engine Fuel Specification Regulations.
Every tank of Biogold™ biodiesel we produce carries independently tested fuel certification.
