| Abstract | |
Green manufacturing (GM) is the environmental benign manufacturing of products with a minimal negative impact on the natural environment. Research studies on GM have been increased in the last years with particular focus on the application of Life Cycle Assessment (LCA). However, the manufacturing industry still faces some barriers and challenges that hinder the application of green manufacturing in practice. Regarding to managerial barriers, many authors highlight that the isolated use of LCA and other tools/techniques are limited in view of supporting the promotion of an effective implementation of GM at the shop floor area. Thus, this thesis was proposed to overcome part of such gaps. The present study was aimed at developing and testing a new GM methodological framework to environmentally evaluate and monitor manufacturing processes. For this, the GM methodological framework was based on a bibliographical research, where 333 articles were found and systematically analyzed. As result, the GM methodological framework was organized into ten different steps, and three main phases: pre-assessment, environmental assessment and monitoring, and post-assessment. Concerning the practical testing of the GM methodological framework, two case studies were carried out: 1) the production of medium density particleboards for consumption by the residential and commercial wood furniture sector; and 2) the production of exhaust valves for using by automotive vehicles. Case study 1) highlighted the hot pressing process of wood-based panels, due to the consumption of electricity and the local airborne emissions of free formaldehyde. The hot pressing process showed potential to affect not only into the manufacturing environmental impacts, but also into the upstream and downstream life cycle stages. Case study 2) pointed out the centerless grinding machining of the stem of automotive valves, due to the electricity and cutting fluid consumption. However, the grinding machining process was not effective to influence into the environmental impacts of other product\'s life cycle stages (e.g., use, post-use). Based on the case studies results, it was proposed three simplified versions of the original GM methodological framework in order to improve its applicability into manufacturing industries. (AU) | |
