Biodigester technology
Human waste disposal in innocuous form is an ever growing problem leading to aesthetic nuisance, threat of organic pollution & several infectious diseases in epidemic proportions due to contamination of ground water and drinking water resources in highly populated and developing countries, like India. Less than 30% of Indians have access to the toilets. In rural areas about 10% of houses have toilets and rest of the people go to open defecation. Population in the cities although have better access to the toilets but only to the tune of ~70%. Untreated waste is responsible for several diseases like, dysentery, diarrhoea, amoebiasis, viral hepatitis, cholera, typhoid etc. taking the life of lakhs of children annually.
Biodigester technology has been developed by Defence Research Development Organisation (DRDO) for resolving the problems of un-decomposed human waste. The innovation degrades and converts the human waste into usable water and gasses in an eco-friendly manner. The generated gas can be utilized for energy/ cooking and water for irrigation purposes.
The process involves the bacteria which feed upon the faecal matter inside the tank, through process which finally degrades the matter and releases methane gas that can be used for cooking, along with the treated water.
What is a biodigester?
A biodigester is a system that biologically digests organic material, either anaerobic (without oxygen ) or aerobically (with oxygen). Microbes and other bacteria break down organic materials in a biodigester.
WHY IN NEWS
Biodigester Technology' was recently in news as Defence Research and Development Organisation (DRDO) will install its eco-friendly bio-digester units across the facilities operated by Maharashtra Metro Rail Corporation (MAHA-METRO), which help conserve water and protect the environment.
