The produced gas can be recovered and used either directly for cooking and lighting or it can be transformed into heat in a gas heater system or into combined heat and power (CHP) in a cogeneration unit (MES et al.

The benefits of agricultural small-scale biogas plants. The digestate is rich in organics and nutrients, almost odourless and pathogens are partly inactivated. The pressure exerted by the rising gas can be used to transport the gas to the collection vessel or directly to where it is going to be used. The gas forms in the slurry and collects at the top of the chamber, mixing the slurry as it rises. It also facilitates the collection of the biogas, a mixture of methane (CH 4) and carbon dioxide (CO 2) produced in the fermentation processes in the reactor.
