Dorset Dairy Will Run On Energy Distilled From Food Waste

12 July 2011

Food waste from the production of cream, milk and fermented dairy products such as soft cheese and yogurt will be recycled to create enough energy to power most of the production process at BV Dairy in Dorset

The facility - which received £1.7m from the AD Demonstration Programme - was opened yesterday (11 July 2011) by Mr Bob Walter, MP for North Dorset.

The plant is capable of processing 80,000 tonnes of waste each year, which in turn will provide the majority of the electricity used in the manufacturing process at the dairy, which churns out 15,000 tonnes of dairy products each year for the food service and food manufacturing sectors. This is achieved by sending the biogas to a Combined Heat and Power engine installed on site.

Surplus electricity created will occasionally be exported to the national grid and the heat generated by the facility will be used in the AD process - any excess will be used in heating and cleaning processes in the factory, and also in the cheese making process.

Previously the unavoidable waste material - washwater from the factory, permeate/whey from cheese making and other dairy rich liquids - were treated at the local sewage works, but treating the waste onsite reduces the company's sewer disposal costs and generates renewable energy for use in the dairy.

Marcus Gover, Director of the Closed Loop Economy at WRAP believesthemarket, including investors, developers and end users, should be confident of AD as a reliable, safe and profitable resource efficiency process. He said: "With industry and Defra, WRAP has taken significant steps to de-risk the technology, developed robust tools to help break down the barriers and facilitate confidence at all stages of the process.

"AD is a growing part of the resource efficiency solution, capable of creating renewable energy, and stimulating the green economy and improving the sustainability of commercial agriculture. We really see it as huge opportunity for the UK".

Jim Highnam, Managing Director at BV Dairy said: "We are proud to be pioneers in AD for the UK food industry. The BV Dairy AD plant demonstrates that the technology works and, judging by the interest in our plant from food manufacturers, we expect to see many more companies using AD to generate renewable energy from unavoidable food waste."

Walter, MP for North Dorset added: "I have always maintained that micro-generation of our energy needs is one of the best and simplest ways in which we can reduce our carbon footprint at the local level, whilst minimising any negative impact on our beautiful environment.

"It is vital that companies take responsibility for reducing their carbon footprint and I applaud BV Dairy for taking the initiative. This local company is, quite rightly, committed to driving down the amount of waste they produce and have my full backing."
