It all started years and years ago on a visit to an embryonic C.A.T. in Wales http://www.cat.org.uk/index.tmpl?refer=index&init=1
I met a chap there who said his claim to fame was that he was the first person in the UK to have a shower in water heated by his own waste, and showed us the rear of the latrine block. Buckets of festering goodness knows what was happily making biogas for these guys to use. Once the organic material has been processed by the relevant bacteria, it is compost and can be returned to the land. Fascinating. Well I thought so.
Having lived all my life in the country, and for the last 21 years without mains drainage or mains gas, and as a card carrying environmentalist, the idea of using waste to provide energy has always been always lurking somewhere in the recesses of my mind (sad, yeah I know). I'd already done a fair bit of research on small-scale biogas production in recent years for a work related project, and had come to the conclusion that China or India were the places to go if you really wanted to know anything in detail. I spent a good deal of time exchanging emails with a plastics manufaturing company in India, who make small plastic biogas digesters in varying sizes and types. They could not have been more helpul. If you look here you'll see what I'm on about. http://www.sintex-plastics.com/deenabandu.htm
