Recent trends in waste to energy solutions for solid waste management

Abstract

The solid waste management has become a great concern in several countries due to its diverse constituents. Solid waste generation rates are imposing incredible pressure on environment and hurdles in achieving sustainable goals, thus, nowadays it is one of the global key issues. It directly or indirectly affects aesthetic, environmental, social, and economical aspects. Solid waste management (SWM) is a crucial collective approach for solid waste generation rates, collection, storage, segregation or sorting of waste, transportation, recycling, recovery and disposal methods of remaining leftover residues of solid wastes. The inadequate, improper and inefficient waste management systems are responsible for contributing toxic elements into various dimensions of the environment, hence affecting human health and triggering additional environmental crisis. The disposal of solid waste is a very challenging task in every part of the world due to linked health risks and potential impacts on the environment. This study gives an emphasis on different technologies for converting solid waste into energy. Waste to energy (WTE) or energy from waste technique is a proven viable eco-friendly solution for the solid waste management issues with controlled emissions and it also finds helpful in generating revenues from discarded waste materials.
