Resumo. Devido ao aumento da preocupação ambiental no setor empresarial, o modelo de gestão ambiental recebeu maior atenção para as estratégias e as práticas voltadas para o uso racional dos recursos naturais, minimizando os impactos causados pelo processo produtivo no meio ambiente, como também para o bem-estar dos funcionários. Desta maneira, o objetivo consiste na análise bibliográfica de gestão ambiental realizado no Brasil, levantando os impactos ambientais causados pelo setor sucroalcooleiro, os certificados aplicados para este setor, os métodos de monitoramento e compensação dos danos causados e o desenvolvimento tecnológico aplicado aos resíduos industriais. Foi possível concluir que a preocupação ambiental transformou o cenário empresarial atual e, com um plano de gestão ambiental eficaz, agrega uma visão positiva com os clientes, como também incentivos fiscais pelo governo e ampliação da lucratividade.Palavras-chave: Gestão ambiental; Resíduo industrial; Bagaço da cana-de-açúcar; Desenvolvimento tecnológico.
Abstract. Environmental management of industrial residues:analysis of management and reuse of waste from the sugar and alcohol industry. Due to the increased environmental concern in the industrial sector, the environmental management model for the greater attention to strategies and practices aimed at the rational use of natural resources, minimizing the impacts caused by the productive process without environment and wellbeing of employees. In this way, the objective is the bibliographic analysis of the environmental management in Brazil, taking the environmental impacts caused by the sugar and alcohol sector, the certificates applied to the sector, the methods of monitoring and compensation of the damages caused and the technological development applied to the industrial waste. It was possible to conclude that environmental concern has transformed the current business scenario, with an environmental management plan, add a positive vision with the clients, as well as tax incentives by government and increased profitability.
The present research aimed to develop natural rubber (NR) hybrid composites reinforced with treated ultrafine calcium carbonate/carbon black (CC/CB). The influence of CC/CB with various filler ratios (50/0, 40/10, 30/20, 20/30, 10/40 and 0/50) on mechanical properties and cure characteristics of the vulcanizates was investigated and their reinforcing efficiency was compared aiming to achieve the best ratio for CB partial substitution as compared to composites with CC and CB incorporated separately. The CC30/CB20 composites reached around to 17 MPa similar strength at break response compared to CC0/CB50 (16.83 MPa). Elongation at break increased 48% in relation to CC0/CB50. Hardness maintain similar values compare to high concentration of CB composites. Crosslink density results revealed similar chain number in rubber matrix representing better interaction between CC/CB. Scanning electron microscopy studies also reveal a good filler dispersion between filler particles and matrix. The results shown that the new material can be an alternative filler for partial substitution of CB conserving mechanical properties.
