CASESTUDY: AD Plant South West of England

Updated: Dec 22, 2020

In May 2014, we commissioned an anaerobic digestion (AD) plant in the South West of England. Together with our technology supplier BioConstruct, we installed a 500kW Jenbacher CHP inside a 40ft container. The plant consists of two fermenters that can hold 1800 cubic metres each, and one 4200 cubic metre storage tank.


Both maize and gras are grown on-site which are utilised as the predominant feedstock (80% maize silage, 15% gras and 5% slurry).


In November 2016, the AD plant was further expanded with the installation of a second 250kW CHP. Additionally, a dryer was installed to further reduce the carbon footprint of the plant. In the same year, we introduced ADvance biochar and silphie.


4CleanTech continues to manage and service this AD plant and its CHPs.
