A consortium of UK universities is working on developing a novel anaerobic digester that will treat pit latrine waste and transform it into a safe and valuable product. Physico-chemical characteristics of fresh human waste and pit latrine sludge are being determined. This is informing the development of a bioreactor containing biofilms, or slimes, of several microbial ‘trophic’ groups growing preferentially on distinct surfaces and materials. The ecologically-engineered bioreactor design will optimise the efficiency of the treatment and underpin successful digestion of high-solids waste. The potential use of the digestate will be reused in agriculture to recycle nutrients and prevent environmental, and watercourse pollution. Attitudes to sanitation, as well as to resource recovery from, and reuse of, waste, are being investigated so the participatory sanitation planning process can work effectively.
