[Stoves] Biodigester construction in Bolivia (Video)

Wed Jan 16 15:42:04 CST 2008

Hi Richard.
I knew about these tipe of compact biodigester a few months ago. It looks very interesting for urban areas and semiurban areas. 
about if the ARTi one looks 'light years ahead of the cow digester' could be true as good looking, but for us the important issue are the rural families that have different requirements than urban o semiurban ones. 

For example, we work some times at isolated areas (no road) and you need to transport the material on the back of the people or with mules. So a compact biodigester will be more difficult to transport.
We want biodigesters made with materials that anyone could buy in bolivia, in any market,  so anyone can build his own biodigester.  
We use tubular biodigester because the families want to use the efluent as fertilizer. If you use compacts tanks, you dont know for how long have been the efluent inside the digester. A tubular biodigester insurance that the effluent has been long time inside and has been digest.
About the guide design and manual installation document will be free because there are lots of information about these tipe of tubular biodigesters, free information, and this document is trying to put together the theorical and practical part with the experience of this years in Bolivia. So there no new invention, just only has been the developments of the works of other people (Botero, Preston, Rodriguez, Aguilar, Harris...) to adapt it to Bolivia and the altiplano. 

For urban families, the AD solution looks great, as well for rural families with no interest in the fertilizer. But for rural families looks like the tubular polietilene biodigester looks more appropriate technology. so i think that both biodigesters design are good, but with different objectives.
