“…Impacts caused to the environment by some types of waste can cause irreversible damage to the environment. As an example, there are many problems related to alkaline batteries and cellular batteries, which contain toxic metals, such as mercury, lead, cadmium, among other materials [2,3]. In addition, disposing of post-consumer polymer materials of various natures is problematic and causes serious damage to the environment [4].…”

Studying thermal behavior is very important for monitoring the quality of polymers on an industrial scale. Commercial geomembranes are materials with low permeability that can be used for multiple purposes, such as geotechnical engineering in liners for potable water. They can also be used as liners for waste liquid, e.g., sewage sludge and soil coverings for landfills. In this paper, the mechanical and thermal behavior of four geomembranes with thicknesses around 2.1, 1.9, 1.7 and 0.8 mm, sold in Brazil by different companies, was evaluated. Thickness, density, tension, puncture and tear resistance and carbon black content were used to characterize the properties of these materials. Thermogravimetry, differential thermal analysis, differential scanning calorimetry (DSC) and dynamical mechanical analysis (DMA) were used to examine the evolution of these geomembranes thermal behavior. Moreover, activation energy of the thermal decomposition was estimated from non-isothermal kinetics. The results obtained by thermogravimetry showed that the geomembranes have a different thermal behavior from each other. Data obtained by DSC showed a widening of the melting peak after the second heating. Activation energy values obtained by the Flynn-Wall-Ozawa and Capela-Ribeiro isoconversional methods for each sample showed variations between them. Based on the DMA experiment, the store modulus (E 0), loss modulus (E 00) and tan d showed different behaviors for the 0.8-mm sample and no significant changes in the other samples. Concerning the mechanical properties, it can be observed that the density and black carbon data have compatible values between the samples.

“…The so-called recyclable materials are subsequently reintroduced into the production system and contribute to the generation of new products. In parallel, non-recyclable ones, mostly organic matter, are submitted to recovery processes, such as, for example, composting and RDF manufacturing [33], ( [35], pp. [53][54].…”

Pathways to Urban Sustainability: An Investigation of the Economic Potential of Untreated Household Solid Waste (HSW) in the City of São Paulo

The depletion of natural resources, the useful life of landfill sites, and the amount of garbage accumulating all challenge public policy to manage urban solid waste. We identified the economic potential for unused solid waste (HSW) in São Paulo in 2018 to be USD 637,633,836.04 through descriptive quantitative research and documentary analysis in the collected data. This amount comes from five sources, with the majority coming from internalizing private cost credits (45.58%), followed by recycling (42.21%), carbon credits (5.46%), refuse-derived fuel (3.77%), and organic compounds (2.98%). This potential assumes the implantation of waste sorting plants that generate jobs, reduce public expenses, and provide environmental benefits such as forest protection, water, and minerals. The environmentally adequate final destination of HSW constitutes an economic and socio-environmental measure that enables the reverse logistics of the business sector and urban sustainability. Consequently, the economic potential of HSW, generated from its sorting and marketing, could provide a positive contribution with the mitigation of environmental impacts, in addition to income generation and social inclusion.

“…Determinados fatores como o crescimento demográfico, a melhora do nível socioeconômico da população, o desenvolvimento de novos hábitos e a intensificação do consumo podem impactar de modo que interrompam a renovação e a recuperação dos elementos naturais, prejudicando o equilíbrio entre o desenvolvimento econômico, social e a conservação do meio ambiente (Prado Filho & Sobreira, 2007). Assim, as políticas públicas podem ser utilizadas para incentivar a adoção de condutas ambientalmente corretas (Ferreira, Macedo, Pimenta & Siqueira, 2015 A abordagem e a priorização do tema economia verde na Rio+20 evidencia a necessidade políticas econômicas voltadas para a melhoria do bem-estar social, com foco a conciliar interesses econômicos e preservação ambiental.…”

Resumo O presente estudo teve como objetivo analisar a relação entre o desenvolvimento dos municípios do Estado de São Paulo e o montante do Imposto sobre Circulação de Mercadorias e Serviços (ICMS)Ecológico recebido pelos mesmos, no intuito de apurar se esse tipo de compensação contribui no desenvolvimento municipal. Para atender o objetivo do estudo fez-se uso do modelo regressão linear múltipla, onde o Índice Firjan de Desenvolvimento Municipal (IFDM) correspondeuà variável dependente e as variáveis explicativas foram população, PIB/Per capita e Repasse de ICMS Ecológico. Como resultado da pesquisa observou-se que no Estado de São Paulo, o ICMS Ecológico consiste em uma política de compensação aos municípios, que abrigam áreas de preservação e mananciais de abastecimento e o repasse do mesmo possui relação significativa com o desenvolvimento.Nota-se, certo crescimento nas discussões relacionadas à necessidade de políticas públicas voltadas ao meio ambiente e a ampla preocupação social relacionada à preservação ambiental torna-se determinante para investigar a relação entre o desenvolvimento econômico e social dos municípios em detrimento de suas áreas de preservação.
