Can toilets produce biogas?
Under it, a toilet is connected to a biogas digester using a PVC pipe. Faecal slurry flows into the digester with gravity, following which, cattle dung, water, and kitchen waste is regularly added to it to produce biogas, which is then used by families as cooking fuel or for other purposes like heating water.

How do Bio-digester toilets work?
Bio-digester toilets are designed to convert human waste into gases and [fertiliser]. The zero-waste biodigester technology uses psychrotrophic bacteria like Clostridium and Methanosarcina (these microbes can live in a cold or hot climate and feed on waste to survive) to break down human excreta into usable water and gas.
What happens to human waste in a home bio-digester?
In a home bio-digester for human waste, up to 99.9% gets digested …and is converted into reusable water and methane gas. Disposal of human waste in accordance with conventional systems leads to groundwater contamination and pollution of water resources that can cause an enteric outbreak.
