Small-scale anaerobic digestion revolutionised

Evergreen Gas Ltd, a new British anaerobic digestion (AD) technology provider, will introduce its range of small-AD plants to the UK market at the Energy Now Expo on 15th & 16th February 2012.

The pioneering design which marks a radical departure from conventional AD plants, opens up diversification opportunities for farms and rural communities wishing to benefit from AD.

Anaerobic digestion is a well-established process which has been recently adopted by over 60 farms and rural businesses in the UK. Whilst long-term returns on investment have been favourable for large farms and food producers in the UK, until now there has been no technology focusing solely on the small-scale end of the market.

Evergreen Gas has been set up by leading biogas expert Michael Chesshire in response to this demand. His solution is to come up with a value engineered digester design which abandons the complexity of the conventional AD plant enabling the energy output and the cost of the system to become proportionate.

There are eight sizes of electrical output (35kWe to 250 kWe). For each electrical output, Evergreen Gas offers 3 digester sizes for low strength, medium strength and high strength feedstocks.

The design is simple, robust, cost effective, easy to operate and, significantly, doesn't carry the same high price tag as "conventional" farm-based AD systems says Evergreen Gas Director, Michael Chesshire: “I believe passionately that we can bring small-scale AD to farms and we are firmly focused on this objective. This follows the successful formula used in my two previous AD business ventures.”
