Overview
Household toilet can be connected to a biogas digester. These toilet systems can turn human waste into biogas.
Types of Toilets
At least two types of toilets can be connected:
- pit latrine type without water flush
- pit latrine type with manual 1litre flush
Impacts
- Access to modern energy: The toilet is connected to an anaerobic digesters which produces biogas that can be used for lighting, cooking and generating electricity.
- Fuel switching: Substitution of unsustainably harvested biomass and maintenance of forest habitat, with associated biodiversity benefits and local benefits to soil stability and to the dry season stream flows in the region[1].
- Time saving: Rural women expend a substantial portion of each day gathering fuel wood and cooking
meals. - Productivity: The residue of the process, bio-slurry, can be easily collected and used as a potent organic fertiliser to enhance agricultural productivity[1].
- Health: Connecting biogas digesters to lavatories contributes to improving hygiene and sanitation practices, and the use of biogas for cooking results in a smoke-free indoor environment. [1]
