Improve the Calorific Value of Municipal Solid Waste By Adding Additive Material For Incineration Process
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
Rapid increase in urbanization and per capita income has lead to high rate of Municipal Solid Waste(MSW) generation (0.34kg/capita/day in 2016) and it is expected to have even higher rate of 0.70 kg/capita/day. In many developing countries solid waste is collected from the source and is disposed by open dumping. There is very minimal treatment and very less human control in open dumping. Open dumping has huge environmental impacts. Hence, a better approach to this situation is needed. Many methods like bioreactor landfill have been successfully implemented in many developing countries but these methods have large area demand and large operational and maintenance costs. Also, these methods are centralized incurring large transportation costs. Incineration is successfully practiced in many countries across the world. The high calorific values of the materials in the waste are used to generate thermal energy which can be further transformed to electrical energy. The flue gases can be treated and the pollution load on the environment can be handled easily. Recent trends of MSW composition have shown the reduction in the organic matter content and increased in the material that can be incinerated giving an opportunity to explore the potential of incineration in India. The present study deals with increasing the calorific value of the municipal solid waste in India by adding the low cost additive materials. The additive materials selected were Wood Coal, Coconut Husk, Rice Husk, Bagasse, Engine Oil. The experimentation consists of two parts finding out initial characteristics of MSW and finding calorific value of MSW after adding additive materials with different proportions. The additive materials selected were cheaper and were added in proportion of 20%, 30%, 40%, 50% with the waste that will be incinerated. For 70% Waste + 30% additive material proportion, calorific value obtained from all additive materials are in desirable range 1500 – 2400 kcal/kg.
