Lake District Biogas was established in 2015 with the sole purpose of building the brand new AD system at the First Milk Creamery in Aspatria. The AD system the company constructed  is designed to process a very large volume of whey permeate from the creamery which can produce over 1,000 m3/hour of biogas with a methane concentration of at least 50%. Biogas is stored in the gas dome before upgrading to bio-methane (some gas is also fed to a CHP unit to provide power to run the entire plant).   80% of the gas is fed to a membrane based bio-methane upgrade unit that converts it into bio-methane with a comparable thermal value to North Sea gas.

Downstream treatment of the trade effluent and residues from the process take place in an existing aerobic plant which has been upgraded and enhanced through provision of chemical treatment for nutrient removal.  The residual sludge from the plant is spread on local farmland as a nutrient rich soil improver helping local farmers improve their efficiency and reduce costs. The new plant provides significant treatment and disposal savings providing the creamery with a state of the art facility to handle its residues, reducing costs and carbon emissions, boosting First Milk’s CSR credentials and contributing to energy supply in the community.
