Plastic+Bag+Digesters

There has been a lot of discussion on plastic bag digesters on the [|Anaerobic Digestion discussion group]. There are several basic reports on the making of such digesters, such as those by Reg Preston: Low-cost biodigesters as the epicenter of ecological farming systems [|A combined digester and gasholder - PVC plastic tube biogas unit].

There is a compendium of studies of such plastic digesters in various places (1997/1998/2002) : [|Tubular Plastic Bio-digesters in Tanzania, Viet Nam, Zimbabwe & China, selected & edited by John Furze]

Here is a Vietnamese view from Bui Xuan An : [|Biogas technology in developing countries: Vietnam case study]

The references that David House (17/01/2010) suggested are: [|"The Characterisation of Production and Function of a 15m3 Red-Mud PVC Biogas Digester] [|The Introduction of Low-Cost Polyethylene Tube Biodigesters on Small-Scale Farms in Vietnam] (another from Reg Preston) [|Gas Bio-digester Information and Construction Manual For Rural Families] and one in Spanish by Jaime Martí Herrero: [|Guía de diseño y manual de instalación de biodigestores familiares].
