After being used, the surplus of these resources is discarded, being directly responsible for most of the environmental impacts caused by human actions on the planet and not only in the territory where urban agglomerations are concentrated. Circular Economy arises to meet the need to reverse and contain the current scenario of exhaustion of natural resources and loss of biodiversity, introducing sustainable production and consumption. Its concept has been explored by different segments of society such as industries, academia, NGOs, government entities, among others, with multiple approaches and applications. Thus, this article, from a theoretical framework, explores the origins of the Circular Economy concept, providing a review of the main schools of thought that preceded it, and analyzes the common point of view on the Circular Economy concept. The article also identifies some scenarios in Brazil and in the world, whose countries and regions have stood out for their representativeness in the global context. It concludes with an insight on the current “status”, the future, and transition to Circular Economy.</p> Cecilia Emi Yamanaka Matsumura Heidy Rodriguez Ramos António José Guerner Dias Copyright (c) 2022 2022-07-17 2022-07-17 18 2 10.17271/1980082718220223193 Renewable energies in cities: Perspectives for the use of biogas in Brazil https://publicacoes.amigosdanatureza.org.br/index.php/forum_ambiental/article/view/3194 <p>One of the main challenges for the present and future of citiesare new energy sources that allow good efficiency and low environmental impact. In this sense, this study analyzed biogas, an energy source from the decomposition of organic matter. A theoretical essay was carried out from bibliographical research, with the aim of presenting the current scenario of the different perspectives of production and application of biogas in Brazil, in urban and rural areas of the country. The observed results showed that, in rural areas, the input for the production of biogas comes mainly from animal husbandry, and that the form of use is mainly directed towards obtaining thermal energy. In urban areas, practically all biogas production is carried out in sanitary landfills and sewage treatment plants, given the large amount of excess organic matter from the waste treatment activity. However, even though the country has relatively important indices of biogas production and use, it was clear from the theoretical framework analyzed that not only is the amount generated very low for generation potentials in Brazil, but there is also an evident lack of technologies in relation to biodigesters, in addition to a weak legislation to promote Brazilian biogas, which led to the conclusion that biogas production in the country is proceeding at a very slow pace. The study is limited in terms of detailing the barriers observed, and, therefore, it is suggested that future studies seek an in-depth analysis of these barriers.</p> Letícia Morais Neres Heidy Rodriguez Ramos Copyright (c) 2022 2022-07-17 2022-07-17 18 2 10.17271/1980082718220223194 Photovoltaic Energy Systems Implemented in Public Buildings Located in the City of São Paulo https://publicacoes.amigosdanatureza.org.br/index.php/forum_ambiental/article/view/3195 <p>With the increase of energy consumption and the environmental changes caused by energy generation, it is essential that different sectors of society seek alternative, sustainable and efficient ways to develop their activities. In this context, renewable energies generate less environmental pollution when compared to fossil sources. Among the renewable energy alternatives, solar energy has grown all over the world, thanks to new technologies, easy installation and energy collection, since it is powered by an abundant source with an inexhaustible impact on the earth's surface. Large buildings are considered potential polluters, as they can cause damage to the environment due to the amount of energy they use. The present study aims to analyze the photovoltaic solar system installed in a public building located in the city of São Paulo, specifically the project implemented in the Fazenda do Carmo Municipal Natural Park (PNMFC). A qualitative, single-case study, was the adopted methodology. Data collection was via the analysis of documents and semi-structured interviews with managers and those responsible for the PNMFC projects. The results showed that the generation of energy close to the place of consumption (distributed generation) is a determining factor for energy savings and minimization of environmental impacts. We conclude that public policies of fiscal and regulatory incentives are fundamental for the growth of the use of photovoltaic energy in urban centers</p> Joyce Éllen Santos de Oliveira Heidy Rodriguez Ramos Copyright (c) 2022 2022-07-17 2022-07-17 18 2 10.17271/1980082718220223195 Use of recycled sand as a corrective material for soil acidity in soybean crops https://publicacoes.amigosdanatureza.org.br/index.php/forum_ambiental/article/view/3197 <p>Acidity is one of the main factors capable of reducing the productive potential of Brazilian soils, as it promotes the release of toxic elements for plants and reduces the availability of nutrients. Recycled civil construction and demolition waste (R-CCW class A) is a major environmental problem in Brazilian cities, especially in terms of its illegitimate disposal, causing floods, clogging of galleries and silting of channels, in addition to the proliferation of vectors and pollution. The objective of this study was to evaluate the potential of recycled sand (R-CCW) as a corrective of soil acidity, through soybean cultivation, in an experiment installed in PVA1 yellow-reddish with sandy/medium texture, acid and of low fertility with doses of 10, 20 and 40% of R-CCW, by mass, in Fernandópolis/SP. Variables related to soil fertility and to plants that were subjected to analysis of variance by F and comparison of averages by the Skott-Knott test at 5% probability were evaluated. The results obtained allowed us to conclude that recycled sand from civil construction R-CCW class A has favorable effects in terms of its ability to neutralize H<sup>+</sup> ions in the soil solution and those adsorbed to negative soil charges, important effects as an acidity corrective, in addition to providing increases in the contents of Ca, Mg, SB, CEC and V%, greater development of soybean plants, which indicates that this use is an environmentally correct alternative for the disposal of these residues.</p> Gisele Herbst Vazquez Andréa Cristiane Sanches Mateus Leonardo Welika dos Santos Copyright (c) 2022 2022-07-17 2022-07-17 18 2 10.17271/1980082718220223197
