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

I am presently producing a transitional design for a plastic bag
digester-- it needs to mature and develop some-- but the aim is low
cost, and my 0.75 cu m units presently cost about $15 in parts, $20
in labor (US prices).<br>
