The manual is based on both the Gobar biogas plant and the performance by AREA during the construction of the biogas plant in Kabul.

This is a very low maintenance system and the Chinese had over 6 million bio digesters of this model working in the late 70’s/early 80’s.

The wastes enter the enclosed fermentation compartment at mid-height through a sloping tube or trough.
