More and more electrical and electronic products in everyday life contain batteries, making life more convenient or pleasant. However, those same batteries, when damaged, also increasingly cause these products to catch fires. In the past few months, organisations representative of the industry that manages the collection and treatment of spent batteries and electronic waste (WEEE) and of manufacturers of home appliances and consumer electronics gathered to exchange views about this issue of growing concern in order to design measures to counter the frequent occurrence of fires. A survey among recyclers resulted in a better understanding of the issue of fires in the WEEE management chain. The report, “Characterisation of fires caused by batteries in WEEE”, has been prepared by EuRIC and the WEEE Forum with the active contribution of experts from various organisations including ecosystem, a PRO in the WEEE Forum, and the co-signatories namely EERA, EUCOBAT, Municipal Waste Europe and the WEEELABEX Organisation. It seeks to jointly assess the severity of the issue.
