List of (apparently free) eBooks about biogas production: Biogas Factsheet Methane-Biogas Production Guide (15p) 3-Cubic Meter Biogas Plant Construction Manual (40p) Nepal Biogas Plant Construction Manual (15p) Biogas Production from Manure (6p)

The author of this HowTo biogas digester might be a good resource person : http://www.greenoptimistic.com/about-us/ "To construct a good biogas plant, you should not only respect the dimensions as indicated on the drawing but also follow the correct construction method. Hereunder, in a step-by-step fashion, the right construction method of the 2047 design GGC model biogas plant is given."

A Novel Design for a Biogas Generator in Developing Countries by Joanna Read A thesis submitted in partial fulfillment of the requirements for the degree of BACHELOR OF MECHANICAL ENGINEERING The proposed generator is designed to produce 3.2 cubic meters of biogas per day. This is the amount of biogas necessary for the daily cooking requirements an average family of eight people, the norm in Pabal. Initial conceptual designs are outlined and analysed by the use of a design matrix. The final design is also analysed and suggestions made for further improvements.

Potentiality of domestic biogas plants in China „ It was forecasted that the potentiality of domestic biogas plants is 150 millions on the basis of climate potential and social-economic potential by Some Chinese experts , that may cover of 55% of the household in rural area in China. It means that the number of biogas plants in use will meet the requirement of 20% of potentiality by 2010. „ If we consider the trend of rural economy developing in China, the potentiality should be modified based on two aspects: (1) Industrialization of animal husbandry with fast development speed；(2) the movement of traditional farmer from rural area to cities and towns. „ Approximately, the potentiality of domestic biogas plants in China is among the 80 millions mainly based on the national pig dung potential

Lots of resources about biogas generation DIY

schemes and images on googleimage, showing the large panel of structural options to build a biogas digester, and also the common elemenst of each technical plan

The first result is inn English, it is the guidebook (12 pages) on "Preparing this training material all the important information have been collected from the booklets & research materials". Source : Biogas Training Center (BRC) Chendu, Sichuan, Chaina.

List if several digester projects

more results while adding the keyword "design" it seems the topic is quite largely documented

Aaron from OSE headquarters writes : "as far as current research, we recently interviewed a man to help with our agriculture, and his current farm includes a methane digester designed by 'Biogas Bob':http://www.omega-alpharecycling.com/ "

A selection of stats in English : http://en.wikipedia.org/wiki/Anaerobic_digestion http://en.wikipedia.org/wiki/Biogas http://fr.wikipedia.org/wiki/Biogaz ... and in French and German too look at the page, the guy made a kind of micro SoA and posted it in his blog. You also have a link to a tool in German to calculate the production of a biogas digester

Lots of contacts of representatives that were at this event...
