Asepsis will implement a highly integrated and sustainable system that resolves the problem of waste collection in urban slums. Using a lowcost and durable squat toilet, they provide a dignified alternative to the poorly kept, overcrowded and potentially dangerous public toilets that are currently available in Dharavi, Mumbai. By connecting the waste received in these toilets to the biogas industry this initiative will redefine waste, transforming it from a source of disease to a catalyst for change.
