One way to recover and revalue a product is by remanufacturing, which is defined as the process of recovering a product to its original specifications, promoting the reuse of materials and improving its quality and functionality. However, the context of the remanufacturing industry faces difficulties and is considered unstable and inefficient if compared to manufacturing. In this sense, this paper aims to propose a cell layout based on lean concepts and adapted to the context of remanufacturing, aiming to minimize waste, reduce variability and thereby increase efficiency. The cell layout proposal was based on a literature review and researchers＇ practical experience in the area. This layout can provide the flexibility to handle the variations inherent in the context of remanufacturing, boosting product recovery and related environmental issues.展开更多

We have carried out a pilot study about environmental impacts during the manufacturing process of PV （photovoltaic） modules and compared between the energy requirement for the production of PV cells and modules and generation throughout the life time of the finished good that is PV module. It was taken into account the generation of environmental aspects and impacts in the manufacture of monocrystalline silicon PV modules （consisting of three components： silicon cell, fiat tempered glass and aluminum frame）, and an analysis of a grid-connected PV system using an energetic alternative in residences was considered. Results show that, this kind of renewable energy is really clean and can be considered as a way to change the energy technology.展开更多
