Optimization of Solid Wastes Disposal Strategy by Fuzzy Topsis Method

The non-biodegradable wastes have been increasing widely day by day. These wastes not only cause harm to the environment and its resources, but also they have an adverse impact on the human health causing a number of health problems. In order to control this issue, a number of approaches have been done and carried out by the hosts. In the present article, we are discussing this issue taking into consideration certain factors and strategies. The factors of waste disposal were identified to be human health, waste reduction, sustainability, cost effective and environmental benefits using the disposing strategies such as landfills, incineration, energy transform, reuse and recycling. The nonbiodegradable wastes include plastics, construction wastes, metal scraps, rubber tyres, man-made nylons, polyesters, glass, cable wires, cellophane, CDs, DVDs, processed wood, styrofoam, aluminium cans and bottles. The survey was carried out using the Fussy Topsis Method, which is a multi-criteria decision making optimization tool. It helps us in making the best choice out of the available options. The results obtained revealed that recycling is the most efficient method, whereas the landfill is an unpleasant option of solid waste management.
