Desafios ambientais na indústria automobiliística: uma análise do processo de reciclagem e reutilização de materiais

This research has as main objective the analysis of the auto industry has done to reduce disposal of solid waste in its production process as much as to facilitate the recycling of cars after they complete their life cycle. Despite the auto industry is not one of the most polluting in terms of its production process, it produces a good that is causing major pollution. In despite of the great current concern in seeking to reduce the emissions of pollutants by vehicles, as important as the quest for cleaner fuels is the study of how to dispose of old cars. Even if the car production does not increase significantly each year in relative terms, we must consider the fleet of used cars that still circulates in the world. Ending the mammoth “cemeteries” of automobiles, however, it is not so easy, even because the car is composed of various materials, which in many cases are not easily separable. In addition to an overview, the research seeks to examine the possible advances in Brazil related to the process of auto recycling

Aspectos técnicos e ambientais da incorporação de novas tecnologias no setor sucroalcooleiro: produção de hidrogênio e gaseificação do bagaço

The purpose of this work is to study the incorporation of hydrogen production (Case A) and the process of gasification of sugarcane bagasse associated with combined cycle gas turbine and steam turbine (Case B) for Distillery Pioneers process. These technologies can be used to improve the energy supply in the sugarcane mill. Initially the processes for obtaining sugar and ethanol from sugarcane is discussed, with a theoretical introduction to hydrogen, the process of steam reforming and gasification of biomass (bagasse) by inserting a turbine associated with the recovery boiler gas. Subsequently makes up the energy and exergy analysis of the incorporation of the above technologies. In end stage makes it an ecological analysis considering or not the carbon cycle (photosynthesis), to determine the levels of emissions of pollutants, carbon dioxide equivalent, indicators of pollution and ecological efficiencies associated with technological developments proposed. It is concluded that hydrogen production by steam reforming of ethanol and gasification of bagasse are viable alternatives from the point of view of technical and environmental applications in the biofuels industry, contributing to the development of the sector in the country

Aspectos técnicos e ambientais da incineração de resíduos sólidos urbanos: considerações sobre a proposta para São Paulo

A tecnologia de incineração no gerenciamento de resíduos sólidos urbanos é empregada de maneira intensa em diversos países do mundo. No Brasil, além da sua utilização eventual em resíduos de serviços de saúde, há uma proposta para implantação de duas usinas de grande porte visando ao tratamento térmico de resíduos sólidos domiciliares na cidade de São Paulo. Através de uma revisão bibliográfica sobre o tema, são apresentados os principais parâmetros técnicos e ambientais desta tecnologia, entre eles os mecanismos de combustão e de formação de poluentes, os tipos de equipamentos empregados, as formas de manejo e disposição de cinzas e escórias e os métodos de controle e redução de emissões atmosféricas como gases ácidos, material particulado e metais pesados. Também é feita uma revisão do atual conhecimento técnico-científico sobre dioxinas e furanos relativamente à incineração de resíduos sólidos urbanos. A partir desta base teórica pesquisada e da análise dos Estudos de Impacto Ambiental e dos Relatórios de Impacto Ambiental das usinas de incineração de Santo Amaro e Sapopemba, conclui-se que tais incineradores, na forma como são propostos, não apresentam o nível tecnológico necessário para atender às normas de operação e emissão de poluentes vigentes em países onde há legislação regulando esta atividade.

A ideologia da encenação: uma análise dos aspectos cênico/ideológicos da encenação produzida pela indústria cultural

The research that led to this dissertation adopted a set of scenic/ideological aspects inherent to the productions of the Culture Industry as its object of research. The intellectual output of Theodor W. Adorno and Max Horkheimer underscored the approaches on this subject, since it provides the same set of scenic/ideological features to be explored because, according to the authors, scenes produced by the culture industry are linked to the dominant ideology, since they act in favor of maintaining the status quo. The first objective was the definition this set of features inherent to the scene produced by the culture industry, through the exploration of literature produced by Adorno and Horkheimer, so it was possible to define a set composed of nine elements: Construction of characters as characteristic types; Stereotypes; Naturalization of Stereotyped language; Simplistic playwriting; Reuse dramatic formula; Love and sexuality as themes of plots; Utilization of tragic element; Objetive representation; Approximation of fiction and reality. The second goal was the analysis of scene produced by the culture industry nowadays, so that it was possible to verify if any scenic/ideological aspects indicated by Adorno and Horkheimer in the mid-twentieth century were present among the productions from this beginning of the twenty-first century. Through the analysis of three soap operas produced in Brazil in 2012, it was found that the nine scenic/ideological aspects as indicated by Adorno and Horkheimer appeared in the observed productions. Additionally, a new scenic/ideological feature, not indicated by Adorno and Horkheimer is present: the merchandising

Este trabalho tem como finalidade a elaboração de um projeto na área ambiental denominado Manual de Boas Práticas Ambientais para a Indústria do Mobiliário de Madeira. Para conseguir atingir o objetivo proposto, inicialmente foi efetuado um breve enquadramento ao subsetor do mobiliário de madeira a nível nacional, recorrendo à bibliografia disponível apoiada em dados estatísticos de suporte. Foram caracterizados os dois concelhos alvo de estudo, Paços de Ferreira e Paredes por apresentarem a maior concentração industrial no subsetor a nível nacional. Procedeu-se à descrição do processo produtivo da indústria do mobiliário de madeira com a identificação dos seus principais aspetos ambientais. Posteriormente foi aplicado um questionário para verificar como as empresas do subsetor nos concelhos alvo de estudo tratam as questões ambientais da sua atividade industrial. De forma complementar, realizou-se um caso de estudo na empresa IKEA Industry Portugal, Lda, onde foi elaborado um diagnóstico ambiental detalhado com incidência nas boas práticas ambientais. Finalmente foi elaborado o Manual de Boas Práticas Ambientais para a Indústria do Mobiliário de Madeira.

Conflitos ambientais e progresso técnico na indústria mineira e metalúrgica em Portugal (1858-1938)

This chapter explores the relationship between environmental conflicts and technical progress, trying to understand, in the case of large mines of the Iberian Pyrite Belt, in Alentejo, how emerging environmental problems conditioned the performance or led to the search for alternative technical solutions, taking as chronological limit for this observation the beginning of World War II. In the absence of the archives of the companies, the research was based on existing administrative documents in the state archives (mining engineers reports, the licensing of mining activities), on reports and documents published in specialized mining press, in particular, the Bulletin of the Ministry of Public Works, Trade and Industry, the Journal of Public Works, Trade and Industry (both in Portuguese), and finally in the local press. Despite that limitation, the information available shows that in global competition markets, the success of the British enterprise in Santo Domingo had the active search for new technical solutions for the creation and adaptation of existing knowledge to local problems in order to maximize the mineral resources available. The early development of the hydrometallurgical processes for the treatment of poor ores, named ‘natural cementation’, can be explained as the way these companies tried to solve problems of competitiveness, boosting economies of scale. Thus, they transferred the environmental costs previously limited to agriculture to more fragile social groups, the poor fishermen of Guadiana River and of Vila Real de Santo António. Therefore, the hydrometallurgy of pyrites was developed locally, pioneered in Santo Domingo that allowed the survival and expansion of the British company from the late 1870s, that is, at a time when most small mines shut since they were not able to compete globally. Through different consented and regulated processes (judicial), through conflict or parliamentary mediation, the State imposed exceptionally additional costs to companies, either for compensation, the imposing the application of remediation measures to reduce the environmental damage in some cases, thus contributing to derail some projects. These cases suggest that the interaction between local conflicts, corporate behavior and technological progress proves to be complex. This article aims to contribute to the debate on economic and social history between the environment and technological progress, arguing that the fixed costs and economic imponderable social risks were factors that encouraged the companies to search for new solutions and to introduce innovations since that would allow the expansion of their activity. In this process the companies sometimes faced environmental dilemmas and unforeseen costs with consequences on the economy of firms. The nature of the knowledge needed to address the environmental problems they created, however, is of a very different nature from that knowledge needed to face the environmental burdens that were inherent to the development of its activity.

O passado e o presente nos conflitos ambientais na indústria mineira e metalúrgica

This chapter reflects on several forthcoming key topics on environmental social conflits in historical perspective, namely, the relationship between the expansion of extractivism and the reactive and preemptive conflicts, the role of scientists and scientific discourses on social mobilization, the environmental movements and the empowerment of the poor, the strategic response behavior of large mining corporations. The conclusive analysis looks for continuities and contrasts between contemporary environmental conflicts and the conflicts of the past, often identified as 'peasant conflicts' over industrial polution.

Ecogenômica de archaea e monitoramento de comunidades de procariotos redutores de sulfato: aplicações na indústria de petróleo e gás

The human activities responsible for the ambient degradation in the modern world are diverse. The industrial activities are preponderant in the question of the impact consequences for brazilian ecosystems. Amongst the human activities, the petroliferous industry in operation in Potiguar Petroliferous Basin (PPB) displays the constant risk of ambient impacts in the integrant cities, not only for the human populations and the environment, but also it reaches the native microorganisms of Caatinga ground and in the mangrove sediment. Not hindering, the elaboration of strategies of bioremediation for impacted areas pass through the knowledge of microbiota and its relations with the environment. Moreover, in the microorganism groups associated to oil, are emphasized the sulfate-reducing prokaryotes (SRP) that, in its anaerobic metabolism, these organisms participate of the sulfate reduction, discharging H2S, causing ambient risks and causing the corrosion of surfaces, as pipelines and tanks, resulting in damages for the industry. Some ancestries of PRS integrate the Archaea domain, group of microorganisms whose sequenced genomes present predominance of extremophilic adaptations, including surrounding with oil presence. This work has two correlated objectives: i) the detection and monitoring of the gene dsrB, gift in sulfate-reducing prokaryotes, through DGGE analysis in samples of mDNA of a mangrove sediment and semiarid soil, both in the BPP; ii) to relate genomic characteristics to the ecological aspects of Archaea through in silico studies, standing out the importance to the oil and gas industry. The results of the first work suggest that the petrodegraders communities of SRP persist after the contamination with oil in mangrove sediment and in semiarid soil. Comparing the populations of both sites, it reveals that there are variations in the size and composition during one year of experiments. In the second work, functional and structural factors are the probable cause to the pressure in maintenance of the conservation of the sequences in the multiple copies of the 16S rDNA gene. Is verified also the discrepancy established between total content GC and content GC of the same gene. Such results relating ribosomal genes and the ambient factors are important for metagenomic evaluations using PCR-DGGE. The knowledge of microbiota associated to the oil can contribute for a better destination of resources by the petroliferous industry and the development of bioremediation strategies. Likewise, search to lead to the best agreement of the performance of native microbiota in biogeochemical cycles in Potiguar Petroliferous Basin ecosystem
