Batteries are crucial for the functioning of information and communication technologies (ICTs). Improving their design, prolonging their lifespan, improving their recyclability and preventing the dumping of waste batteries can lower their overall energy consumption, reduce exposure of humans and the environment to hazardous substances and reduce global greenhouse gas emissions. This Recommendation provides guidance on the sustainable management of used batteries in ICT equipment and the environmentally responsible management of waste batteries from ICT products, including waste prevention, minimization, recycling, recovery and final disposal. It also provides information on best practices in recycling batteries for dissemination.
