Solid Waste Management of Dehradun City based on its Physical and Calorific Energy Potential

Abstract

Due to increase in population the rate of generation of solid waste keeps on accumulating, putting pressure on the city and its environment. Municipal solid waste in city is unorganized due to deficiency of infrastructure, proper disposal plan and well managed dumping site. In this case study, an attempt has been made to quantify the sanitation facilities in Dehradun city for both present and future populations with respect to solid waste management system (SWMS). This study aims to find solutions related to (SWMS) and possibilities of resource recovery. It is done by collecting data through visits to organizations such as Pay Jal Nigam, Uttarakhand Jal Sansthan, Municipal Corporation, Solid waste plants, STPs and survey from local people. It has been observed that segregation of solid waste, negligence of waste collection, segregation, inadequate numbers of bins and transfer stations are the main issues that need to be addressed for effective solid waste management facilities in the city. Experiments involved proximate analysis, calorific content of MSW and reduced derived fuel (RDF) from MSW. The results of proximate, and calorific value test shows that municipal solid have high organic content, high moisture content and C/N ratio shows acceptable criteria for anaerobic digestion which can produce 1.5 m of biogas/ kg of biomass. MSW of Dehradun city has potential to generate power of 8.68 MW, thus waste to energy plant is recommended near the waste treatment plant in the city as waste management option. Shishambada waste treatment plant generates around 200MT of RDF per day which can be used for energy generation.
