“…Esses materiais são aproveitados para a geração de bioenergia, com a tecnologia atual, não gera poluição para o meio ambiente e chega a produzir 500 kWh por tonelada do resíduo. Estudos recentes relatam a potencialidade tecnológica do bagaço da cana, com propriedades mecânicas, térmicas e acústicas quando incorporado há polímeros, como também a importante viabilidade econômica do resíduo e por ser uma alternativa renovável em relação aos materiais sintéticos (Naguib, 2015;Putra, 2013).…”

“…A cana-de-açúcar tem diversas aplicações na indústria, sendo principalmente para a produção de açúcar e álcool, combustível, como também biodiesel e na cogeração de energia a partir da queima do bagaço da cana (MAPA, 2016). Atualmente, diversos autores estudam as potencialidades tecnológicas do bagaço da cana, com ênfase no desenvolvimento de materiais sustentáveis e reaproveitamento do excesso de resíduo do processo produtivo (Naguib et al, 2015;Putra et al, 2013).…”

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.

“…Besides improving the use value, using sawdust for the manufacturing of WPC could help minimize waste [3]. The advantages of agrowastes such as bagasse and rice straw are renewable, lowcost materials and easy availability [7]. The mechanical properties of WPC could be enhanced by adding a coupling agent [8,9].…”

Commercial wood flour of pine (Pinus densiflora) was used as an experimental material. It was milled with different milling times 0, 10, 20, 30, 40, 60, and 120 min to investigate the effect of their particle size distribution on the mechanical properties of the wood-plastic composite. Two kinds of drying conditions, 7 days of freeze-drying at a temperature of −45 °C and heat drying (80 °C) for 24 h were applied. Polypropylene and maleic anhydride-grafted polypropylene were used as a matrix and the compatibilizer of the wood-plastic composite compound, respectively. Particle size analysis showed that an increase in the time of ball milling decreased the wood flour size. However, an excessive milling period of time longer than 40 min corresponded to an increase in the amount of aggregation. Scanning electron microscope images showed the existence of aggregation for the wood flour with 120 min of wet milling time. As the particle size decreased, mechanical properties of wood-plastic composite increased for up to 30 min of wet milling time and then slightly decreased. This behavior might be due to aggregation. The optimum mechanical property was obtained at 30 min of wet milling time under freeze-drying conditions.

Influence of Sawdust Bio-filler on the Tensile, Flexural, and Impact Properties of Mangifera Indica Leaf Stalk Fibre Reinforced Polyester Composites

et al. 2018

Abstract. The need to have biodegradable composites is aloft in today's market as they are environment friendly and are also easy to fabricate. In this study, mangifera indica leaf stalk fibres were used as reinforcement along with saw dust as bio-filler material. Unsaturated isophthalic polyester resin was used as the matrix. The fibres were treated with 6 % vol. NaOH and neutralized with 3 % vol. of dilute HCl. Treatment of sawdust fillers was done by using 2% vol. NaOH solution. Hand layup method and compression moulding technique was used to fabricate the composite laminates. Specimens for evaluating the mechanical properties were prepared by using water jet machining. The results indicated an increase in tensile, flexural and impact strength of composites with addition of sawdust upto 3%. Further addition of the bio-filler resulted in decrease of mechanical properties.
