Abstract Long considered as being non-hazardous waste, discharged alkaline and saline cells are collected, sorted and crushed. The zinc and manganese that make up the electrodes are usually subjected to acid extraction prior to being recovered by electrolysis. The objective of this article is to raise awareness among persons involved in this sector for the fact that operators working near cell recycling units are not exposed solely to zinc and manganese. Indeed, the presence of particularly toxic substances such as benzene and iridium in these types of cells has been reported. Consequently, this fact needs to be taken into account when designing processes and adapting the methods for protecting workers.
