Not all BioDiesel is the same. Its quality varies according to the refining process and the feedstock used. Certain properties of BioDiesel, such as the Cold Filter Plugging Point and Pour Point can vary considerably, mainly according to the feedstock used to produce the BioDiesel. In colder climates, such as in Northern Europe, these properties relate to how "sticky" BioDiesel is and its consequent ability to flow within the fuel system of an engine.

These properties are vital considerations for both our customers and their end users. Why? Because, put simply, poor quality Biodiesel can stop and potentially damage an engine with severe consequences for both distributors and their customers.

Flex Fuels works to the highest quality. We believe that our customers and their end users deserve and will expect nothing less than the best. Therefore Flex Fuels will only use the highest quality feedstocks.

Flex Fuels’ core feedstock is Rape Seed Oil ("RSO") most of which we plan to extract from the primary farm product oilseed rape (also known as Canola) at our own dedicated Crush Plant in Cardiff, Wales.

Why Rape Seed? RSO is one of the very best feedstocks and the European Norm (the quality standard, EN14214) was written around it. BioDiesel produced primarily from RSO has excellent Pour and Cold Filter Plugging Points and can be safely mixed and used at reasonably high blends within Europe.

lenders (our customers) can be certain that their brand will not be damaged by a relatively small component of their overall product. As such, RSO derived BioDiesel is the natural quality choice for blenders.

Flex Fuels will use other environmentally friendly, feedstocks to produce BioDiesel, blended with RSO to produce quality BioDiesel. Certain feedstocks will not be used by Flex Fuels, not only because they produce an inferior product but because some of these feedstocks have contentious and negative environmental implications, including carbon balance, social considerations and habitat destruction.
