A IMPORTÂNCIA DO USO DE CINZAS DE RESÍDUOS URBANOS NA ECONOMIA CIRCULAR

Abstract

: After the industrial revolution, due to technological innovations, it was possible to increase productivity and the total volume produced and consequently the increase in waste. The linear method of production is based on the increasing extraction of natural resources, in which products from these resources are used until they are discarded as waste, generating an increasing volume of waste especially in urban areas. The objective of this study was to identify the products and inputs generated from the ash in the process of incineration of hospital and industrial waste, enabling the generation of raw material for new products used in the industry, especially in civil construction, such as: reuse of ash from urban solid waste (MSW) for cement and concrete, red ceramic, concrete block and dry mechanical treatment of incineration slag. Incineration, in addition to contributing to the National Solid Waste Policy, in reducing waste and recycling contributes to the generation of thermal and electrical energy and collaborates with sustainability leveraging the circular economy with less waste reflecting in the environment in conscious and sustainable consumption. The reduction in waste generation reduces the need for sanitary landfills and shows itself as an alternative to meet a growing demand for urban waste. The circular economy comes to show that it is possible to include new opportunities in the production cycle of the product with diversification of raw materials and waste inputs generated. The incentive to selective collection can and should contribute to sustainability, seeking an efficient management in the generation of urban waste.
