The BRAC Water, Sanitation and Hygiene (WASH) programme in Bangladesh is planning to convert faecal matter from pit latrines into commercially viable fertiliser, biogas and electricity. The aim is to complete the sanitation chain by making material from millions of pit latrines safe and economically productive. Babar Kabir, senior director of the BRAC WASH programme, says that there is a sound business case for investment in bio-energy units that could generate electricity on a large scale.
