“…A coleta seletiva, conforme Rocha (2012), se configura como uma alternativa ambientalmente correta e sustentável, pois ajuda na reciclagem dos resíduos, diminui o volume depositado nos aterros e evita o descarte em locais inapropriados, que, na maioria das vezes, acabam por prejudicar a saúde pública e o meio ambiente Rovaris, 2017).…”

O objetivo dessa pesquisa foi avaliar, historicamente, o comportamento (de aumento ou redução) de alguns indicadores da coleta seletiva praticada no Brasil, tomando como referência os dados do SNIS do período compreendido entre 2011 e 2020. Os dados analisados foram extraídos do Diagnóstico do Manejo de Resíduos Sólidos Urbanos publicado anualmente em sites oficiais do Governo Federal. Foram escolhidos 08 indicadores: Taxa de cobertura da coleta seletiva porta-a-porta em relação a população urbana, Taxa de recuperação de recicláveis em relação à quantidade de resíduo domiciliar e público, Massa recuperada per capita, Relação entre quantidades da coleta seletiva e resíduo domiciliar, Incidência de papel/papelão sobre total de material recuperado, Incidência de plástico sobre total de material recuperado, Incidência de metais sobre total de material recuperado, Incidência de vidros sobre total de material recuperado. Foi possível concluir que a coleta seletiva no país aumentou (conforme o comportamento positivo de 06 indicadores), mas de forma não significativa, ou seja, sem o ritmo necessário. Provavelmente, muitos fatores contribuíram para esse quadro: a baixa adesão da população, falta de campanhas publicitárias e a falta de recursos financeiros por parte das prefeituras, significando que grandes volumes de recicláveis ainda estão sendo desperdiçados e lançados em lixões e aterros sanitários.

The increasing urbanization and industrialization of modern societies has led to a large-scale production of solid waste, and its proliferation is therefore a global problem with immediate consequences for public health and the environment. Urban solid waste must be managed and controlled so as to reduce its volume and hazard, minimizing the damage of environmental pollution and the impacts in the population health. Currently, the most common waste control techniques are recycling and composting. Such techniques are known as tools that allow waste reuse. In this context, the use of recyclable materials in civil construction has been increasing day to day. However, in Brazil, no approach was found regarding material for the civil construction that is based on domiciliary solid residues, as the ecological brick. In this work, the thermal comfort of the ecological brick was analyzed, a brick of low environmental impact and of easy applicability that can be used to improve the thermal comfort of the Brazilian constructions in general, including the housing for the low-income population. The main objective of the study was to verify the effectiveness of the ecological brick regarding the thermal comfort. The methodology consists of measuring the thermal comfort in a reference model of low-income residence with ecological bricks masonry produced with waste from urban solid waste. Changes in the envelope were soon made, such as the addition of coating mortar and white paint and the replacement of the ecological brick masonry with the ceramic brick masonry with and without coating in order to compare the values of the residence internal temperature. The measurement was performed by computational simulation with the EnergyPlus® software using the real-scale prototype of the popular standard Brazilian house, on the typical summer day. In the results, it was noticed that the residence of ecological bricks obtained a sensitive difference in temperature in comparison to the residence of solid ceramic bricks. The prototype built with ecological brick contributed to better conditions of thermal comfort, as it provided lower internal temperatures, and, consequently, lower heat gain. Therefore, it was verified a change in the values of thermal transmittance and delay related to the behavior of masonry in the different environments of the building. As for the influence of the addition of the coating mortar and the external paint with a light color, it was observed that there was a significant improvement in the thermal performance of the masonry. Therefore, for a better thermal comfort of the users of the buildings in the bioclimatic zone-8, it is indicated that the seal composed by ecological bricks is towed and its facade painted with light colors.
