The process has been designed to maximise simplicity and efficiency using sodium or potassium methylate catalyst and methanol at the correct concentrations, flow rates and temperatures.

For pre-esterification treatment of high FFA oils, if required, an enzymatic process is employed.

The system requires the regular supply of catalyst and other consumables such as filters. For every 2000 litres of fuel produced approximately 250 litres of catalyst is consumed.

Catalyst and service maintenance is delivered through a dedicated dealer network to the site of each BioCube™. Using safe, robust containers there is little handling of the chemical required.
