Alternativas para o aproveitamento de resíduos da produção madeireira em Santarém-Pa

Abstract

The forest produces raw material for obtaining various products that can be classified as timber and non-timber, in 2018 Brazil was the ninth largest producer of hardwood sawn wood in the world, producing about 2.4 million m³, 20.24% of the national production was exported, which corresponds to US$ 221,987,000.00. During the wood transformation process, 40% to 60% of its volume is used, the rest is converted into waste, often incorrectly managed, which can cause environmental degradation and loss of profit for the company. In this context, this study aimed to analyze the solid waste management model of a large sawmill located in Santarém-PA and propose sustainable alternatives for its proper use. For this, on-site visits and semistructured interviews were carried out to collect information related to the company's production process, identification of the generation of environmental impacts and the possibilities of improving environmental performance, and environmental regularization with the State Secretariat for the Environment and Sustainability ( SEMAS). According to SEMAS - PA in Santarém there are 17 companies in the wood sector that are in environmental compliance, and together they annually handle a volume of 126,226.3 m³ of processed wood. The target company of the research generates a total of 450 m³ of wood waste per week, with a part of this waste being used as a source of energy (wood tips) and the surplus (sawdust) is donated to potteries and ceramics close to the enterprise. It was observed that due to the large amount of waste generated, storage problems occur, as alternatives for reuse that add value and prevent environmental degradation, briquetting and making Small Wooden Objects (POM) is suggested.
