22 April 19
According to Olufunke Cofie, International Water Management Institute, Africa Regional Office, Ghana, inorganic fertiliser is not sufficient to add nutrients to the soil for crop production. Cofie says that excreta contains valuable nutrients like nitrogen, phosphorous, potassium and organic matter. Municipal solid wastes (MSW), which are also dumped without planning, contain phosphorous, nitrogen, phosphorous, potassium and carbon. Co-composting of faecal sludge and MSW complement each other and provide missing components to each other as per Cofie. The microbial population in the final product is reduced enormously says a 2009 study by Cofie. The study says that the final product complies with the 2006 standards of the World Health Organization for the safe reuse of faecal sludge.
