A Review of Recycling of Human Excreta to Energy through Biogas Generation: Indonesia Case

The use of waste to produce biogas not only limited to the waste from nature such as agricultural waste, food waste, or cattle manure; but can also use human waste hereinafter called human excreta. The use of human excreta for biogas generation considered beneficial either in the term of process or environment. It is at the same time produce energy and reducing environmental problem that caused by unmanaged human excreta disposal. In Indonesia, the main use of biogas itself is for cooking and generating electricity. The huge population and inequality deployment of electricity supply in Indonesia becomes a strong reason in developing biogas system from human excreta. This review paper will discuss utilization of human excreta to produce biogas as alternative energy source and the prospect of this technology in Indonesia.
