[Digestion] Costs of different household biodigesters

[Ivo Oliveira]

Hi all,

I would like to know if anyone knows or have a good estimate of the cost of
the following small scale biodigesters:

1- Plug-flow polyethylene biodigester type (like the ones in Bolivia)
(between 1-10 m3).... I don't know if it's possible to build one with such
small size like 1m3
2- Chinese fixed-dome (between 1m3-10 m3)
3- ARTI type biodigester (1-2 m3)

Thanks,

Ivo Oliveira
