What is Anaerobic Digestion?  Read the BREG Guide to Anaerobic Digestion and Composting.pdf.

Although AD is technically well understood the take up of this renewable technology has been patchy in the UK.  The larger sewage treatment works commonly use AD to treat sewage and some dairy farmers have digesters to manage their cattle slurry, which is a major source of methane emission in the UK.  Following the German example Britain has a growing number of on-farm digesters for energy production dealing with slurries but also using crops such as maize and silage to boost the biogas yields.  These digesters are 100′s to 1000′s of cubic meters in capacity and are the size of buildings, the scale of these digesters is an example of the technology being implemented now but is not necessarily the optimum scale.

BREG has identified a need to better understand AD at a smaller scale; to lower the barriers for land based enterprises to make use of AD to add value to food production.  To this end BREG has secured funding to demonstrate micro Anaerobic Digestion in West Dorset .  We have purchased a 600 litre, BioGastronome provided by Methanogen UK and are in the process of deploying a stand alone system to run through the summer of 2012.

The Blog page is where we will be reporting our progress and findings and also a place to discuss the various aspects of Anaerobic Digestion.

This Project has been part financed by the European Agricultural Fund for European Development 2007-2012: Europe investing in rural areas, and is being delivered through the Chalk and Cheese Local Action Group with Defra as the Managing Authority.  Details of the European Fund for Rural Development can be found here.
