The Waste & Resources Action Programme (WRAP) has financed a demonstration facility for Clearfleau's high-rate anaerobic digestion system.

The BV Dairy, near Shaftesbury in North Dorset, is the location of the first commercial high rate liquid digestion plant in the UK dairy sector, one of five projects funded by the Department for Environment, Food and Rural Affairs, in WRAP's Environment Transformation Fund.

Clearfleau has installed its trial digester unit on the site as part of the final design phase. The system receives effluent pumped from food manufacturing facilities and converts it into renewable energy to replace existing fossil fuels.

It can accommodate a range of organic material containing sugars, oils or fats, as well as unused or waste ingredients and reduces effluent discharge costs, as well as the site's carbon footprint. Dairy trials will enable regulatory authorities and planners to assess this system. The project is also supported by Dairy UK as a demonstration site for the entire dairy sector.

The full-scale anaerobic digestion plant will generate 45,000kWh of electricity and 30,000kWh of surplus heat from about 1,000m3 of effluent per week, according to Clearfleau. It will replace a significant proportion of heat and power within BV Dairy's milk processing business.
