Powerday has announced its collaboration with Willen Biogas in the development of a new anaerobic digestion plant in North London.

The 25,000 tonne facility is currently under construction and is expected to be commissioned late in the summer of 2015. The site at Cattlegate Farm in Potters Bar is easily accessible from central and north London and already has a grid connection for the export of 1mw of electricity. The digestate produced as a by-product of the process will be returned to the land to increase yields and produce healthier plants on the farm’s own arable land.

The collaboration between the family owners of Cattlegate Farm, Oakwood Plant and Powerday will see Powerday marketing the facility to existing and potential customers. Funding has come from the Green Investment Bank and Foresight Group. Powerday will be entering into a further collaboration with food waste specialist Olleco who will provide the company with dedicated food waste collections.

Simon Little, Sales & Marketing Director, Powerday says: “This partnership will give Powerday a stronger food waste offering based on the best available technology for the treatment of food waste, and bespoke collection vehicles. Our clients who produce food waste, particularly the Rugby Football Union at Twickenham, London Irish and Saracens Rugby Club, will be among those that will benefit from this investment”.

Adrian Williams, Director of Willen Biogas and Co-owner of, Cattlegate Farm says: “We have worked hard to develop this project and to secure the funding to make it happen. The plant has been developed as a merchant plant, and we are therefore delighted to have Powerday working with us to build the food waste inputs that we will need’.

This latest announcement follows the official opening of the Cattlegate Farm composting facility which took place earlier this month. The windrow composting site is licensed to accept 25,000 tonnes a year of green waste, providing a significant new piece of recycling infrastructure for London and Hertfordshire.
