These reports are now linked from the Biogas Wiki page: http://biogas.wikispaces.com/Links. Just a reminder (to Vianney Tumwesige and everyone else) that this is a good place to start looking for more information in biogas.

Hi, It has taken some time for me to post this, but here is the Royal Agricultural Society of England's (RASE) report on small scale UK on-farm digesters that we talked about earlier this year. There is a long version which contains all the case studies ( http://www.rase.org.uk/what-we-do/core-purpose-agricultural-work/AD-Full-Report.pdf ) and a shorter version which talks about barriers and benefits ( http://www.rase.org.uk/what-we-do/core-purpose-agricultural-work/AD-Short-Report.pdf ) Several of the AD systems proved particularly interesting. One was a self-built system which topped up the digester heat using thermal solar. The farm was a virtual showpiece for renewable energy, having solar PV, ground source heat pump, a wind turbine, thermal solar and a digester! (Case study 10.4) A second, which had been running for more than two years, had automated de-gritting, so that cows could be bedded on sand or ash. It used a very low parasitic load on the mixing (typically about 1W/m3) and had an elevated belt press separator. (Case study 10.5) A third had a three-tank system which produced wonderful digestate and did gas scrubbing in a covered post-store. (Case study 10.9) I hope those of you who were interested in the report enjoy reading it as much as I enjoyed talking to the farmers and putting it together! Kind regards, Angie Bywater |
