Message-ID: Content-Type: text/plain; charset="iso-8859-1" Anyone have an electronic copy of some biogas burners and biogas light designs handy? Can do the hard and dirty, am more interested in refinements such as adapting for biogas/air mixtures and "proven" tricks/technologies. Would appreciate it.

One can actually install an air blower and install some pipes under the floor to carry out aeration process after completion of the anaerobic process, that will also solve the problem about when you open the door of the digester. Hopes it will answer your question. William Tan SP MULTITECH Malaysia [email protected] > > Today's Topics: > > 1.

Thanks Frank Dear List-Serve Fellows, The non-profit I work for has been convinced for several years of the pivotal importance of compost, and of the superiority of decentralized approaches to organic waste processing (to minimize transportation costs, energy use and emissions, and to maximize the appeal of participation). We are open to organics processing that produces energy as well as compost. However, we are concerned that the price tags of most anaerobic digester may require a scale of operation that prohibits decentralized approaches, and may place compost in a subordinate position, at best. Has anyone worked on, or does any know of, low-cost, small-scale anaerobic digester systems -- rural and/or urban; ones that may be better components, better partners, in a decentralized strategy? Thank you very much.
