To Bioenergy subscribersthis is one of the messages (which might interest some of you) posted to the 2 one-month paper discussion sessions on Anaerobic Digestion and Biogas technology (5-30 Oct) and Biofuels (2-30 Nov) that is now conducted vis the LISTSERV mailing list mailto:et-w10@segate.sunet.se .
Two papers are now being discussed: * (1) David Riggle (USA) Anaerobic digestion for MSW and industrial * wastewater. http://www.ias.unu.edu/proceedings/icibs/riggle * (2) Francisco A Moog (Philippines) Promotion and utilization of * polyethylene biodigester in small farming systems in the Philippines * http://www.ias.unu.edu/proceedings/icibs/moog

Jacky Foo <mailto:foo@swipnet.se> asked me: >could you provide some

>developing countries ?
In our databank on AD on full-scale organic solid waste treatment plants we collected about 150 plants all but one located in developed countries. These data include co-digestion plants. The top 5 countries are according to our data: Germany (77), Denmark (29), Switzerland (12), Sweden (10) and The Netherlands (8).
In developing countries the work done in India by the Ministry of Non-Conventional Energy Sources is probably known by most of you. In the framework of their huge UNDP-funded Biomethanation programme., AD-plants for solid waste treatment will be built.
According to my information: research is going on at the Univeristy of Sao Paulo in Sao Carlos, Brazil and the Universidad de los Andes (Uniandes) in Bogota, Colombia. Prof Giraldo of the Uniandes wrote an interesting article in which he compared composting and AD.
Concerning the anaerobic treatment of brewery wastewater, we counted 207 full-scale plants, many of them are located in Latinamerica, in particular Brazil, Mexico and Venezuela. The earlier reactor types are almost all UASB, the later ones either EGSB or IC, These reactor types are more appropriate due to lower gasloading rates (needed for mixing) that you get with the low average COD and the moderate temperatures of this wastewater.
