If you can make it, a short description, typical problems, materials needed.:
The biodigester consists of a sealed tank that holds biowaste and a means to collect produced gases. Use requires a way to mix the biomatter. One also needs to pipe off the gas and to dry off the effluent. When planning, one always needs to estimate how much organic waste can be collected in a day for putting in the tank and to consider which model of the digester is the best, as they are built differently (either concrete or plastic). One also must use adhesives and tools.
