Life cycle assessment of cell phones in Brazil based on two reverse logistics scenarios

Abstract

This article is a result of a cell phone collection obtained at the Center for Information Technology Renato Archer (CTI) under the AMBIENTRONIC Program, an initiative that supports the Brazilian electronic sector in the development of technologies for sustainability. The objective of this article is to assess two reverse logistic scenarios of cell phones using the technique of life-cycle assessment (LCA). The first scenario reflects the current scenario in Brazil, where batteries are recycled in Brazil and the other parts of the phones are outsourced to Europe. The second scenario is a proposal of full treatment in Brazil. The results indicate that the second scenario has a lower potential impact with important reduction of acidification, photochemical oxidation, eutrophication and the use of non-renewable energy. Furthermore, fully implementing reverse logistics in Brazil will enable socioeconomic benefits from the sale of materials and the generation of employment and income.
