Quality management.

A focus on quality is central to the ReFuel culture, believing this to be a key factor in building customer confidence and loyalty.

Raw materials

We are committed to the use of waste vegetable oils as the most environmentally responsible raw material feedstock. However, by definition, the quality of waste oil which is sourced from various processes throughout the UK - does vary. We do not process the types of oils with known performance disadvantages (waxing, cold flow, etc) and test all delivered raw materials to confirm quality and composition, rejecting any not meeting our strict quality criteria.

Process control

Each stage of our manufacturing process is designed to ensure complete transesterification of WVO into biofuel such that any by-products are either converted or removed. This requires careful temperature control, accurate measurement of catalysts and additives, and sufficient time for the process to complete.
