Value Added By-products Recovery from Municipal Solid Waste
The last two decades in India have driven with a high-paced industrialization and urbanization which has drawn the world’s attention. To achieve a developed nation’s status with high GDP growth rate, India has to renew its focus on sustainable growth and development. However, on the other side of reaching higher economic growth has oversized the consumption of the natural resources, raised waste generation and hence environmental degradation. The commerce and industries will need to devise a system where each and every act is inherently sustainable and restorative aiming to build an enduring society. India is facing great disproportionality between increasing urbanization and the available services and resources. One such area is the provision of municipal solid waste management facility, where India has a lot of scope and need for research to fill the inadequacies. The current MSW disposal services are insufficient and need to be updated with more profitable recovery, recycle, and reuse technologies to reduce the huge expenditure incurred in treatment processes. This paper mainly focuses on the post-processing by-products of the municipal solid waste treatment in the form of leachate, refused-derived fuel (RDF), and compost which has potential for agricultural and industrial application. Best available technologies have been focused based on methods to reduce the fraction of waste by recovering materials, energy, and value-added transformed products of waste processing from sanitary landfills. Several literature and articles report the scope for utilizing these fractions as compost in agriculture as manure, RDF as fuel for incineration in industries, e.g., in cement industry, for curing in construction, and leachate as nutrient and water source for green belt development. With our growing attentiveness on deleterious environmental effects of existing waste disposal methods, there is a significant onus of answerability for efficient waste management. The rapid urbanization in India would generate higher demand for scientific and sustainable municipal solid waste (MSW) management techniques along with the pivotal role of green technologies.
