Waste from animals and household can have negative and harmful impacts on the environment, i.e. land-water resources, as well as on health because of degradation of sanitation and living conditions. However, when sorted and treated can be useful sources conservation of natural resources, for improves economy, for producing energy, (biogas or electricity, and fertilizers e.g. different forms of organic fertilizers). It is simply because leftover food and animal manure are organic matter rich in carbon which is a basic element for production of biogas. Breakdown of organic matter in the absence of oxygen, i.e. anaerobic digestion with anaerobic bacteria, can produce biogas. Biogas can, also, be produced by fermentation of biodegradable materials such as manure, sewage, municipal and green waste, plants and crops.
