Clearfleau video of BV Dairy's Anaerobic Digestion Plant goes live

On-site Anaerobic Digestion (AD) is a cost-effective approach to handling liquid residues and co-products on food and drinks processing sites. Clearfleau’s commercial reference plant, completed in early 2011 is reducing the carbon footprint of BV Dairy’s milk processing site. This plant was funded by WRAP, through the Environment Transformation Fund (ETF)* and is located adjacent to BV Dairy’s Shaftesbury site in Dorset.

BV Dairy is a demonstration facility for the entire food sector. The liquid feedstocks generated on-site are pumped to the AD facility. In the digester tank, bio-degradable fats and sugars are converted into biogas that is fed to a combined heat and power (CHP) engine to generate renewable electricity (and surplus heat). By using the energy on-site, BV Dairy has reduced its effluent treatment charges and energy costs, as well as its carbon footprint.

Clearfleau’s AD technology can deliver at least a 95 per cent reduction in the COD load of liquid bio-effluents fed into the digester, making it more efficient than other high-rate AD systems. In BV Dairy’s anaerobic digester, the liquid retention time is only five days, while bio-degradable solids are retained for up to 50 days to optimise biogas output.

Clearfleau is now working on several UK dairy projects, as well as building on-site plants for Diageo at one of their malt distilleries and for Nestlé at one of their manufacturing sites. Both plants will be operational by the end of 2012. The company is also running its mobile SSPP trial unit on a number of sites as well as looking at possible projects outside the UK.

Richard Gueterbock, Marketing Director at Clearfleau Ltd. who produced the video with Dorset based Studio 2 Media Ltd, commented:

“This video shows our commercial anaerobic digester in build and during operation. This liquid AD plant can digest whey and other or by-products, as well as liquids that are difficult to digest with existing AD technology.”

*About the ETF:
WRAP (the Waste & Resources Action Programme) helps individuals, businesses and local authorities to reduce and recycle waste. It supervised the AD Environmental Transformation Fund (ETF) on behalf of DEFRA (the Department for Environment, Food and Rural Affairs) and DECC (Department for Energy and Climate Change). The ETF AD projects were announced in June 2009 and construction on the 5 selected sites started in 2010.
