Poly-panel Household digester, with stand and bucket

Poly-panel Household digester, with stand and bucket

Note: Our hope is to work on this design during the spring and summer of 2025, producing plans for sale.

The fundamental principle of this design is the same as that of [The_Cube], since it is a “poly panel” digester. Such digesters have sides (and a top and bottom) made from rigid polystyrene foam welded to plywood or particleboard, can be put together to form a hermetic (leak-proof) insulated box: a heatable biogas digester. Note that Puxin- or Home Biogas-style plastic and un-insulated, un-heated digester designs are wonderful for use in somewhat less than half the world: the approximate half that tightly hugs the equator. We in the US, Europe, and most of the rest of the world are not in that half, and so as a result, unless you put that un-insulated, un-heated digester into a greenhouse or some other sort of heated environment, the wonderful digester will only give you biogas during half the year. Oops.
