Sulabh International has been constructing and maintaining over 7500 public toilet complexes spread all over India, out of which 190 are linked with biogas plants. Biogas produced from human excreta is channelized and used for different purposes e.g. cooking, lighting, warming oneself during winter, heating water and electricity generation. The engine to covert biogas to electricity is run 100% on biogas. But its unpleasant colour, odour, presence of pathogens and high BOD content limit makes it unsuitable for direct discharge into a water body. For safe disposal of human waste, it was important to make the effluent free from odour, colour and pathogens.
