Detailed Narrative Description of Project:
Solid waste management is one of the major problem in Bangladesh. The city dwellers of all small and big cities of the country produce a  large quantity of house hold waste daily. The government officials of the city/pourashava with its small manpower are combating the situation. They collect the waste and dump in the urban periphery. The toxic leachate also pollutes the surface water and the surrounding soil which can impact the plant and animal life. It also creates aesthetic problem to the nearby community. The over use of chemical fertiliser, in the crop field reduces the soil fertility. To improve the soil fertility bio fertiliser is essential. However, the present research is taken to recover the resource from those household waste for application in agricultural crop fields, to increase the productivity. A Survey was conducted for both agricultural waste and household waste in Mirzapur area and quality and quantity was estimated. The information was collected both at the household and community level, about the waste generated through the agro based processing facilities by questioner survey. A total of 150 families were taken by random sampling. Data was collected regarding the amount of the waste, their views and practices of waste disposal Information was also collected about the availability of other raw materials like poultry litter, sawdust, rice husk, urea etc. Poultry litter was collected from poultry farms and cow dung was collected from beneficiaries and farms. Different types of composts were prepared and their quality was tested. The parameters tested were organic matter, nitrogen, phosphorous tri oxide, sulphur, calcium, magnesium, copper, manganese and boron. The performance of the prepared compost was examined by applying in field with at different compositions with soil and urea. There were 265  families having income over Tk. 10000, 1327 families having income in between Tk. 5000-10000 and 1062 families having income below Tk. 5000 per month. The waste generated by the pourashava dwellers was composed of food waste, vegetable waste, papers and plastics, leaves /branches and woods/straw.
