ABSTRACT

This chapter deals with the description of a technological process for the treatment and recovery of secondary raw materials starting from no-lead alkaline batteries. The primary advantage of this technological choice is environmental protection due to the reduction of pollution at the end of life of such materials. Black paste is the remaining material after the preliminary separation of iron, plastics, and paper from the collected battery wastes. Life cycle assessment (LCA) takes into account the process of selection of exhausted alkaline batteries and the subsequent hydrometallurgical process used to recycle the resulting mass. LCA plays a key role in sustainable production and consumption policies. The LCA method provides instruments to understand the potentialities of clean industrial technologies and processes moving toward more sustainable development. The software used for the study was SimaPro 8.2, produced by the Dutch company Pre Consultant, which is among the most popular software for conducting LCA studies.
