If you would like to make your own Biodiesel regularly it is worth investing in a biodiesel processor (or building your own). A suitable biodiesel processors will heat, mix, settle, and wash your biodiesel – all you need to do is put in the ingredients at the correct time and pump/syphon out the finished product to a storage vessel.

Below are details of biodiesel processors available here in the UK for under £1,000. At this price processors will typically make 50-150 litres of biodiesel at a time and are made of plastic rather than industrial quality stainless steel. If you require more biodiesel processing output than take a look at our over £1,000 UK Biodiesel Processors page for details of processors with outputs from 50 litres to many thousands of litres per day.

Domestic Biodiesel Processors

We first published this article back in 2006. Since then the number of manufacturers of biodiesel processors in the UK has grown enormously, and the processors on sale are now of much better quality and are more reliable and (relatively) easier to use than they were. Below are details of some of the most popular biodiesel processors currently on sale (July 2013) in the UK.

Pictured above is the BioBuddy 125L all-in-one biodiesel processor kit. This processor can make up to 125 litres of biodiesel per cycle from new or used vegetable oil. It is fitted with a fuel dispensing nozzle which makes filling up vehicles very easy. It is priced as low as £699.97 including UK delivery (discounted from usual £999.97). A 200 litre version (BioBuddy 200L) is also available for £999.99 sometimes discounted from its usual £1499.97.

Oilybits Ltd offer a 60 litre and 120 litre biodiesel processing kits. Click here for exploded photographs of the component parts of their 60 litre processor, and their 120 litre processor (both PDF). These truly are kits of parts which need to be assembled with a range of tools. Some expertise in connecting up plumbing fixings would definitely be a help. However, these are very affordable at £425 for both the 60 and the 120 litre basic kits. They also offer fully integrated 120 litre kits for £999.
On the Oilybits website (from where these kits can be purchased) is an excellent and comprehensive Guide to Making Biodiesel which is a must read.
