A pilot program is going into place this summer in Oxfordshire using anaerobic biogas digesters to provide for the natural gas needs of 130 homes. If the experiment gets satisfactory marks it will lead the way for a large scale biogas digester infrastructure in the UK over the next few years. The UK is politically beholden to produce 15% of its energy from renewable resources by 2020.
In contrast to the biogas digester project that I worked on here in Cordova, Alaska the UK system will be using human sewage waste along with organic rubbish to power a much larger digester. If you’re curious about the processes taking place inside of a digester check out the science behind. Here is a “flow” chart I swiped from the BBC’s “Will we switch to gas made from human waste” article:
