Item Análise das propriedades mecânicas do concreto com adição de seixo e polietileno tereftalato (PET)(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) BEZERRA, Antonio Carlos Lapa; ALENCAR, David Barbosa deThe increasing production of plastic waste, particularly Polyethylene Terephthalate (PET), poses a significant environmental challenge due to its long degradation time and negative environmental impact. This study investigates the feasibility of using ground PET as a partial replacement for fine aggregate (sand) in concrete production. Mixtures with 0%, 10%, 30%, and 50% sand replacement by PET were prepared. Tests at 28 days of curing showed that PET addition in certain proportions maintained the required strength and provided environmental benefits, such as reducing natural sand extraction and reusing plastic waste, reinforcing the technical and environmental viability of using recycled PET in concretes.Item Análise do gerenciamento de resíduos da construção civil na cidade de Manaus, sob a perspectiva da sustentabilidade(Instituto de Tecnologia e Educação Galileo da Amazônia, 2023-06-03) PINTO, Cynthia de Faria; SILVA, Simone da; http://lattes.cnpq.br/7260488247107062The generation of waste from the civil construction industry, a reflection of population growth, changes in habits and intense consumption, has been a matter of great concern for the world, since natural resources are finite and nature cannot absorb production. exorbitant amount of waste generated by society. In the city of Manaus, environmental problems, mainly those related to civil construction, are not different from the rest of Brazil. The rubber period at the end of the 19th century and the implementation of the Free Trade Zone in the 1960s were responsible for the growing mass population migration to the capital, thus boosting the growth of the Civil Construction Industry, as well as the generation of its waste. Therefore, the objective of this work is to demonstrate the current scenario of management of civil construction waste in the City of Manaus, from the perspective of sustainability, from data collected in the Secretariats and bodies of public administration, through bibliographies, as well as in the construction sites, verifying the current situation of the final destination of the (RCC), and what are the sustainability practices adopted, aiming at the elaboration of a booklet with the indication of the weaknesses found in the management of the RCC and suggestions of improvement actions, aiming at minimization of impacts on the environment, in order to support decision-making by the public administration and its managers regarding compliance with CONAMA Resolution No. 307 and Law 12,305/2010 (National Solid Waste PolicyPNRS).Item A gestão de resíduo no brasil e implicações das técnicas mais aplicadas no processo de gerenciamento(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-09-14) VIANA, Claudenilson dos Santos; SILVA, Edson Pablo da; http://lattes.cnpq.br/7223548333736671One of the great contemporary challenges for modern societies is the high volumes of solid waste generation, a result of the high levels of population growth and economic development experienced by several countries in recent decades. In this context, this work aimed to investigate aspects of waste generation in Brazil and the main waste management techniques that are reported in the literature. The methodology used comprises a literature review, where recent works were used in order to expose the current scenario of the Brazilian context, as well as waste management techniques used more widely. Through the information collected, it was possible to notice that Brazil has a high generation of waste, with about 216 tons per day throughout the national territory. In Brazil, the most used form of management refers to the use of sanitary landfills, however, landfills require complex management, in addition to a grandiose strip of land. In this way, solutions such as incineration can contribute to waste management both in Brazil and in the world, since it considerably reduces the volume of waste. Other alternatives reported in this study include bioremediation, recycling and composting. It is also noteworthy that recycling, despite being a highly effective method, leads to severe contamination problems, which makes the plants need to have strict controls for cleaning and care, avoiding the contamination of employees. Finally, several measures can be adopted, but they must consider the context in which cities and the respective State are located, aiming to obtain lower costs and greater efficiency.
