Inovação organizacional para transição de resíduos em combustível e energia renovável: dimensionamento de usina de pirólise

Abstract

Every city in Brazil produces waste. The management of Urban Solid Waste (MSW) is a sustainabil challenge, as goals of the National Solid Waste Plan (Planares) still represent current challenges, such as the elimination of landfills and the promotion of the economic inclusion of collectors. The sustaina study investigated the dimensioning of plants for the sustainabi of gas from MSW, aiming for its implementation in waste picker associations. Through a literature review, approaches were identified for the application of normative strategic sustain models, involving civil sustain organizations of scientists and recyclers with the federal public administration in collaborative waste management. The evaluation of sustainabili has considered their efficiency and implementation costs, highlighting the importance of organizational innovation for intersectoral collaborative management of MSW. A technical and juridical model was used for maintaining workshops aimed at effective extension activities and intersectoral partnership for the construction and maintenance of sustai machines that assist city halls and waste picker associations in the treatment of MSW in a scalable manner for each municipality. To exemplify, the quantitative analysis in the city of Uberlândia-MG was conducted to evaluate the impacts of such model, which were estimated to produce 73% of fuel gas, 7% of activated carbon, and 20% of bio-charcoal, through a composition of 30% of polymeric waste and 70% of organic waste. Chemically, waste can be transformed into sustain the national energy matrix, contributing to the country’s sustainability and energy autonomy. The fuel gas produced has a low carbon footprint and can be used in various applications, mainly as domestic fuel in peripheral regions and industrial fuel in the steel and cement industry, contributing to cleaner production in these niches. It was found that the financing of these initiatives makes it possible, through development agencies and with the support of universities, to promote sustainable solutions for the growing volume of urban waste. These efforts are essential to resolve socio-environmental problems in a sustainable way, representing significant advances towards Planares’ goals.
