The Defence Research and Development Establishment (DRDE), a wing of Defence Research and Development Organisation (DRDO), which developed an environment friendly toilet technology called 'bio-digester, has now installed four bio-digester toilets at Vivekananda Nidam in Madhya Pradesh.
The technology, was first used by the defence forces in high altitude, has now been put under trial for commercial purpose in Vivekananda Nidam.

So we thought since we have developed this technology, which is low cost and maintenance free, why not install these bio-digester toilets in other areas as well. Vivekananda Nidam is the first area where we have installed this plant, which is for demonstration," said Lokendra Singh, Associate Director, DRDE.
The bacteria, used in a bio-digester, can convert human waste, releasing an effluent that is free from unpleasant odour and can prevent various diseases caused by human excreta.
The special feature of the bio-digester toilets installed at Vivekananda Nidam is that the Bacteria Anaerobic Digestion process keeps clean and odourless the water emanating from the toilets and whihc can be used for plants.
Below the toilets, a special kind of bacteria is put in the digester tank, which makes the water from the toilets clean and odourless.
The bio-digester toilets are already in use in express trains across India. By Ashok Pal
