Gestão ambiental em cadeias produtivas agroindustriais: um estudo em um aglomerado produtivo da caprinovinocultura no Estado do Rio Grande do Norte

This thesis aims to investigate the perception and behavior of goat and sheep rural producers from Central Cabugi Region of Rio Grande do Norte state, in terms of the sector competitiveness, the cooperation mechanisms, information and environmental practices integration in the supply chain, including their customers, and also among the local producers and other institutions that support this agribusiness cluster. The research problem is related to the environmental impacts from goat and sheep breeding. This problem can also be intensified by the organization of producers in a cluster. Then, it is important to examine how the environmental issues are considered by the rural producers and their perception of their suppliers, customers and the institutions that support this activity. The methodology used in this work involved literature review of the topics of supply chain management, green supply chain, clusters development and sustainable livestock. An exploratory survey research was also conducted by personal interviews using questionnaires. Three statistic techniques were used to compile the gathered data: descriptive statistics, cluster analysis, and Chi-square tests. Two clusters were found in this study, however, the entire sample believes the sector of goat and sheep breeding is a medium competitive activity. On the other hand, for the variables of the importance of environmental practices for competitiveness , perception of environmental impacts and environmental benefits from farm vegetation management , the research found 2 distinct groups of individuals when those variables were analyzed together the green supply chain management group of variables in the cluster analysis. Beyond competitiveness perception, no degree of difference was found for the use of insecticides too. The chi-square tests present that producers having at least elementary education, lands bigger 100 hectares and located in the cities of Angicos or Lajes tend to have a higher perception to supply chain management and environmental awareness issues than those with no or incomplete first-level education, producing in lands smaller than 100 hectares and located in the cities of Afonso Bezerra or Pedro Avelino. The chi-square tests also show the amount of milk produced, family s income and associational condition are not related with the variables used in the clusters composition. In this context, this work contributes to planning clusters development strategies and enhancing the production chain sustainability. This Master of Science Thesis can also help to introduce the environmental variable in the project, assessment and monitoring of development policies as well

Coleta seletiva e compostagem na Vila do Abraão (Ilha Grande, RJ): aspectos e recomendações

Muitos programas de coleta seletiva e Usinas de Triagem e Compostagem (UTC) brasileiras tem se mostrado problemáticos, ineficientes ou, até mesmo, inviáveis. Apesar disso, continua a ser uma solução visada por parte de órgãos gestores e da população. Observando que a coleta seletiva e a instalação e operação de UTC são peças importantes para a prática da reciclagem, dentro do contexto de Gerenciamento Integrado de Resíduos Sólidos (GIRS), verifica-se a necessidade de melhor entendimento dos problemas a elas associados para que haja um melhor planejamento e minimização destes problemas. O presente trabalho tem por objetivo principal a recomendação de diretrizes para um estudo de viabilidade e implantação de coleta seletiva e Unidade de Triagem e Compostagem na Vila do Abraão (Angra dos Reis, RJ), observando as características locais e as dificuldades normalmente existentes em programas de coleta seletiva e em operações de UTCs. A análise, que foi feita através de revisão bibliográfica de artigos científicos sobre estudos de casos brasileiros acerca de coleta seletiva, UTC e compostagem, mostrou que as principais dificuldades associadas a estes programas estão relacionadas: aos custos de operação e manutenção dos programas e das UTCs; às falhas administrativas e operacionais das UTCs; à capacitação inadequada dos trabalhadores; à falta de conscientização ambiental da população; ao desenvolvimento de soluções isoladas (fora do contexto de gerenciamento integrado) e que desconsideram os fatores locais. Também foi feito um levantamento das características locais da Vila através de observações in loco, entrevistas e trabalhos de campo. Sobre a Vila do Abraão constatou-se que ainda são necessários entendimentos entre os gestores locais (subprefeitura, Parque Estadual da Ilha Grande), a população e a municipalidade em Angra dos Reis, assim como, faz-se necessário um estudo mais aprofundado sobre a operação da UTC, incluindo aí as parcerias necessárias (cooperativas, catadores, prefeitura, ONGs etc) e sobre um programa de educação ambiental, para a efetiva participação da comunidade local. Além das recomendações feitas aos gestores locais, são indicados estudos que podem complementar o presente trabalho

Utilização de óleos de origem vegetal em substituição aos derivados de petróleo em composições de borracha natural (NR)

A partir da publicação, em 1994, de um relatório que afirmava que a presença de óleos aromáticos pesados, com altos teores de compostos policíclicos, em formulações de borrachas estaria relacionada ao desenvolvimento de doenças como o câncer, associado ao fato da crescente conscientização ambiental na fabricação de produtos elastoméricos, foi iniciado um estudo sobre a substituição do óleo aromático de origem do petróleo por óleos vegetais de menor risco. Nessa Dissertação de Mestrado foi proposta a substituição do óleo aromático derivado do petróleo por óleos vegetais como o de tungue, palma e linhaça, em composições de borracha natural (NR) contendo diferentes teores do copolímero de butadieno-estireno (0, 10 e 50 phr) e diferentes tipos de carga (negro de fumo N330 e negro de fumo N375). As composições obtidas foram avaliadas quanto a propriedades reométricas, mecânicas e fractográficas. Foi observado que não houve variação significativa na viscosidade Mooney, na resistência à tração, no alongamento na ruptura e na dureza Shore das composições de NR SBR1502 quando o óleo aromático foi substituído pelos óleos vegetais, quando diferentes negros de fumo foram utilizados como carga reforçante e quando foram utilizados teores crescentes de SBR1502. Por outro lado, a resistência ao rasgamento das composições de NR SBR1502 apresentaram melhores resultados quando o negro de fumo N375 foi utilizado. A adição de teores crescentes de SR 1502 levou à diminuição dos valores de rasgo. A natureza do óleo utilizado influenciou esse resultado e melhores valores foram obtidos com o óleo de tungue. Os resultados obtidos foram corroborados pela morfologia do material, avaliadas por microscopia eletrônica de varredura

Avaliação de um biorreator piloto de lodo ativado no controle de odores.

Apesar da importância das estações de tratamento de efluentes industriais (ETEIs) na conservação dos ecossistemas, estas podem ser geradoras de gases com maus odores contendo compostos orgânicos voláteis - COVs. Os maus odores têm sido motivos de protestos e reclamações por parte da população circunvizinha às fontes emissoras. Em virtude da conscientização ambiental, e dos impactos sobre a saúde do homem, o objetivo geral deste trabalho é avaliar a eficiência de um biorreator aeróbio piloto no controle de gases odoríferos emitidos em estação de tratamento de efluentes de indústrias de alimentos. Foi desenvolvido um sistema de difusão de ar odorífero em um reator aeróbio de lodo ativado, hermeticamente fechado, operado no regime de batelada sequencial, durante os dias 14, 21, 23, e 30 do mês de julho.Foram realizadas análises dos parâmetros físico-químicos do lodo ativado utilizado no reator aeróbio piloto, como determinação dos sólidos, DBO5, DQO, OD, pH, temperatura e IVL. A atividade da biomassa do lodo ativado foi avaliada por meio do teste de Respirometria. A eficiência do reator quanto à redução da DQO dos gases foi analisada por meio da absorção dos gases em solução de dicromato de potássio. Para avaliação da mensuração dos odores utilizou-se o método de cromatografia gasosa e espectrometria de massa, quantificando amostras de gases odorantes adsorvidas em tubos de carvão ativado, na entrada e na saída dobiorreator. Os resultados obtidos confirmaram o potencial do sistema de difusão em lodos ativados para o tratamento de gases odoríferos em ETEI, com eficiência de remoção dos COV`s variando de 97,3% a 98,9%.

O comportamento das organizações atuando em clusters de turismo ecológico: a proposta de um modelo de gestão

Esta tese tem como objetivo propor um modelo de gestão para as organizações que participam de clusters ecoturísticos. Os arranjos produtivos locais têm se destacado crescentemente como forma de se buscar vantagens das economias de concentração, não apenas no setor secundário, mas também como disposições locais e regionais mais produtivas para o setor de serviços. O turismo tem crescido nas últimas décadas, tanto nos seus moldes tradicionais de massa, como principalmente na suas novas formas, assim chamadas de alternativas. Uma destas categorias que têm se destacado na preferência de alguns segmentos da demanda turística é o ecoturismo, acompanhando a tendência de aumento do grau de conscientização ambiental e da busca por ambientes que proporcionem contato mais estreito com a natureza. As características sistêmicas do serviço turístico, abrangendo dos pontos de emissão até o destino dos turistas, sugerem a necessidade de um modelo de gestão mais adequado à sua complexidade. A estas condições gerais do sistema turístico, acrescentam-se peculiaridades dos clusters ecoturísticos, pelas restrições ambientais e pela intensificação das relações entre os agentes participantes da prestação desta categoria especial de turismo. A metodologia utilizada no trabalho foi o estudo comparativo de casos múltiplos, compreendendo clusters ecoturísticos formados nas localidades de Bonito ¿ MS, Brotas ¿ SP e o Parque Estadual da Ilha do Cardoso, na região de Cananéia.

Participação de moradores no programa de coleta seletiva em três bairros de Natal/RN: explorando determinantes psico-socio-ambientais

The general purpose of the study was the analysis of residents' participation in the program of door-by-door collection of recyclable residuals in Natal, Rio Grande do Norte. Even though the conception of such program by municipal managers was basically aimed at providing job opportunities and income for the collectors, the main objective of the investigation was to verify whether residents' participation could be attributed to their environmental commitment. Data collection involved three municipal districts and was performed in three stages, with complementary methodological strategies (observation, questionnaire, and interview), and characterized by selfevaluation, by residents, and hetero-evaluation, by collectors. Social, demographic, situational/contextual, and dispositional data were identified to help in the analysis of residents' adherence to the program. Separating and delivering recyclable residuals was the most frequent type of residents' participation, which demonstrates their low level of appropriation of decisions related to the program, taking part on it as passive agents. Two forms of motivation towards participating in the program were found: environmental and social. Despite the first being more frequent, it was associated to lack of environmental awareness related to the process, which may very well imply a mere reproduction of pro-environmental discourse. Motivation towards social issues was strongly connected to philanthropic forms of help. Knowledge was revealed as na important predictor for participation, as well as social networks, formed by neighbors, relatives and friends. Despite the social emphasis in the design of the program, it is possible to conclude that some residents also perceive its environmental benefits, possibly as consequence of a knowledge originated outside the program. Initiatives of environmental education should be promoted in order to minimize the allegation of lack of knowledge as justification for non-participation. Similarly, actions to put together municipal management and population would be welcome, to promote joint decisions towards sustainable styles of life
