Abstract
Indonesia is one of the largest recycler of Lead Acid Battery (LAB) in Asia suffering for lead contamination which is classified as one of the top poisonous heavy metal pollutant. The corresponding Issues have already caused significant public concern. This paper describes a brief overview and comparative study of some pyro metallurgy and hydrometallurgy processes by collecting data of input materials, energy consumption, environmental impact and main products. Subsequently, mass flow of lead and entire cycle of lead recovery process is calculated semi-quantitatively. According to the result, some of primary lead recycling processes can be cut off along with minimizing environmental issues due to the emission products, if the proper management of waste is implemented. This research provides a guideline for the saver life cycle of recovering lead from spent lead paste of LAB aiming to contribute for green efficient cycle of secondary lead in Indonesian Industry.
