Anaerobic Digestion


Cattlegate Farm plans to diversify with the installation of Anaerobic Digestion and Greenwaste Composting facilities.


What is Anaerobic Digestion?

Anaerobic Digestion (AD) is a process of waste vegetable matter or biodegradable material decomposing in an airtight vessel. Anaerobic bacteria digest the product resulting in Methane gas. The Methane is then used to create renewable energy.


What are the benefits?

There are numerous benefits.  The United Nations Development Programme has recognised AD as one of the most useful decentralised sources of energy supply with much less capital investment required than large power plants.


It is a truly green fuel source it enables us to claim Renewable Obligation certificates. We benefit from heat, electricity and Co2. For all concerned a win win situation.


Environmental Impact

As with any planning application Cattlegate Farm has been careful to ensure that the impact on the local environment is minimised and indeed enhanced where possible.  Here is a summary of current information:

Maydencroft Rural states that the developments will have no negative impact on biodiversity. We have noted their views on extra habitat areas and will be actioning these as well as letting over 1.5 hectares of land be used as a wild flower, reptile and amphibian habitat to the North of the proposed Greenwaste composting facility.

MTC Consultants have a very thorough flood risk and water containment report which will be adopted.

Liz Greenwood has prepared extensive and thorough Tree reports and Visual impact for both sites and Tree management and extra planting will be implemented at the first available opportunity.

The Airshed have given us guidelines in a full and detailed report which have been noted by us our Technology suppliers and will be part of the civil engineering requirement.

Light: Low level environmentally aware lighting will be used for the welfare of people on site that will not cause a nuisance at night.

Archaeology: Archaeological Solutions have reported on the site and have found little to no evidence of any Archaeological findings.

Noise: The report by Xergi is very clear and shows that at 10 metres the loudest operation on the site is 65dB(A). With that in mind the nearest residence is the school at over 700 metres from the site on the other side of the railway embankment with vegetation and trees the noise level at the school will be not noticed.

Traffic: Report by Tucker Associates states the proposals will have "No material impact on highway safety or operation."


Technology Supplier: The Technology Supplier for Cattlegate is Xergi who have over 20 years experience in the renewable energy market.  They have won many awards and accolades for their professional an efficient systems.  Further information can be found on
