ABSTRACT- During the last decade product design were enlarged to cope with environmental requirements from materials selection to final assembly and disassembly for recycling. DFE, DFR, DFD (Design for Environment, Design for recycling and Design for Disassembly) are new designing approaches that incorporate the environment issues from the beginning of a product development. In Europe, since October 2000, car makers are supposed to be responsible for their vehicles from cradle to grave. That means that they have to close automotive materials life cycle loop. In fact the strategies adopted by North American and European companies regarding environmental requirements are similar and the way automobiles are being conceived and manufactured from now on is changing the label of this former essentially polluter product into an almost 100 % recyclable one and maybe soon available in zero emission version. But recycling does not intrinsically prevents environmental impacts. For instance, regarding toxic materials such as heavy metals, lead, mercury, chrome and cadmium, new and clean technologies and sound recycling processes management are required avoiding extra environmental impacts. In this scenario the importance of lead batteries recycling is strongly linked to the environmental requirements in both senses claiming for cleaner recycling processes and for technological innovation, such as rechargeable batteries or long lasting batteries for electric or hybrid vehicles. In short new technological trails leading to more efficient batteries, are suppose to have a great impact on recycling process in medium-term and even short-term. Car batteries are recycled all over the world at different rates such at 90 % in European Union and at 50 % in less developed countries. In Brazil we do not have official data on batteries recycling but a case study made at CETEM under my supervision got to a estimated rate on an interval from 65 to 80 %. This article is going to present the main results of this case study and some insights on future development of car batteries for hybrid and electric vehicles.

Key words: bateries collect systems, batteries recycling ; , managing lead recycling;, lead recycling processes
