Integration of city-wide SW and FS management (Bangladesh)

Population increase in most low- and middle-income countries has caused an increase in both solid and faecal waste which has burdened municipalities whose mandate includes sanitation provision and solid waste management. This is coupled with limited finance and technical capacity required for sustainable collection and treatment of waste. This study assessed the potentials for the integration of solid waste and faecal sludge management in Faridpur municipality, Bangladesh, focusing on collection and co-treatment services. Primary data was collected through observation during field visits, focus group discussions and interviews. Solid waste and faecal sludge samples were collected from a co-compost plant and Compost Research and Training Centre, respectively. Technically, proper mixing ratios of the feedstock for composting is necessary as this affects the moisture content and the C:N ratio of the mix. This study found out that proper mix is achieved through the addition of a bulking agent such as sawdust. On the financial aspect, the integrated management of the dried faecal sludge and solid waste was financially viable and up-scaling to the city level may lead to even more profitability in the future. The integrated management of waste in Faridpur would improve environmental protection, allow for resource recovery and reduce municipal budget for collection and transportation of waste.
