Battery waste from household collection is a mixture of everything: various battery chemistries, lamps, pens, whatever garbage you can imagine. Sorting is needed not only to sort out non-battery waste, but also to sort battery chemistries and shapes or sizes to criteria, which meet the unique delivery specifications of final recycling company. To target a most cost-effective recycling with high material recovery yield, sorting services need to achieve a precise differentiation of outgoing battery fractions with a high sorting quality up to 99,5%.
Another challenge of sorting are batteries from WEEE treatment plants. These processes generate a mixture of poorly identifiable primary, secondary and partly damaged batteries. Thus, manual sorting is a knowledge based service, with high stuff training demand and vital support of a fast working analyzing lab. This provides necessary flexibility to achieve every day continuous quality at a permanent changing input material. It explains also that only a part of a battery waste stream in a clean state of single cells can be treated by fully automatized sorting machines (image, X-ray, weight and/or induction).
