Sao Paulo – Brazil 55 11 32745202 edmilson@fei.edu.br Abstract Ever growing costs incurred by solid waste management have forced many developed countries to implement new environmental policies with the purpose of sharing with manufacturers and marketers the costs involved in handling and treating post-consumer waste. The concept Extended Producer Responsibility that emerged in Europe in the 1990s, quickly gained momentum across the continent and a few years later influenced new regulations all around the world. Brazil is one of the most recent countries to adopt the concept through the National Solid Waste Policy that was passed in 2010. This regulatory framework supports the principle of shared responsibility with which manufacturers, distributors and retailers are now responsible for its own post-consumer waste. This research aims at discussing the limitations and perspectives of the reverse logistics model implemented in Brazil. Results indicate that increasing use of multilayer materials, lack of tributary incentives for consumption of recyclable material and high costs of transportation pose a series of challenges to fulfill the legislation targets. Keywords: Extended producer responsibility; design for environment, packaging Introduction The evolution of materials engineering has allowed a significant improvement in fundamental properties of packaging materials which are basically to protect food and several other products, facilitating transport and storage as well as allowing direct communication
