Making biofuel
from wastes


We manufacture biodiesel from used cooking oil and other food wastes at two biodiesel refineries on the east coast of England. We have also built a pre-processing facility to increase the efficiency of our manufacturing operations.

Converting waste oils and fats into biodiesel

Greenergy has owned and operated a biodiesel production processing plant in the port of Immingham since 2007 and has recently acquired a second similar facility at Seal Sands on Teesside.

An ongoing programme of investments at the Immingham facility has created a world-class refinery that delivers unique production efficiencies, with yields as high as virgin vegetable oil facilities, as well as the highest standards of product quality. With the acquisition of a second manufacturing facility at Seal Sands, there are opportunities to improve the performance of both sites further by making best use of feedstock, through technology transfer and sharing of best practice.

Pre-processing waste oils to make them suitable for biodiesel production

Our pre-processing facility at North Cave in East Yorkshire was built as a joint venture with Brocklesby Ltd and operates and acts as a sister site to our biodiesel manufacturing facilities. By using novel technology and processes to upgrade raw materials, it allows us to produce high quality biodiesel from lower cost and lower quality waste materials that we would otherwise be unable to use.

In order to extend our use of waste-based biofuel even further, we have also begun to process biodiesel from the oil and fat in high fat solid foods such as pies, sausage rolls, pastry and crisps. The oils and fats in these foods are extracted and then further purified before we convert (esterify) them into biodiesel. We only use foods which are not fit for sale, for example because they are mis-shapen, overcooked or past their sell by date.
