This article explores the concept of the circular economy based on the use, as base material, of wood residues from the production process of a company that operates in the hygiene and cleaning products sector based at the Manaus Industrial Pole. These residues feed the manufacturing process of a Sustainable Joinery, which, in turn, manufactures custom products, as well as those from its catalog. It is intended to explore the manufacturing process, in the context of the pillars of the circular economy. The methodology of this work consisted of exploring the stages of its manufacturing process, the process flows, the chain involved, and the waste management of this process. In this study, the life cycle stages of raw material supply and end-of-life pathways of wooden pallets were assessed environmentally from different perspectives with lifecycle assessment (LCA). In addition, it reveals the potential to be explored in the region due to the economic opportunities and social and environmental impacts, since, considering only the year 2019, 21 tons of wood were reprocessed, representing an average monthly revenue in the order of $ 5,000.
