Resource-efficient conception of waste electrical and electronic equipment collection groups

  • Critical metals are in great demand by the electrical and electronics industry, so waste electrical and eletronic equipment represents a significant source of secondary raw materials. Owing to low recycling rates and the concomitant supply risks associated with critical metals, the closure of the material cycles is highly relevant to the German economy. Losses of these metals occur from collection until their material recovery, along the entire disposal chain of waste electrical and electronic equipment. This paper develops planning criteria for the design of collection groups to achieve higher recovery amounts of such metals. The aim is to clarify what amounts of metals exist, both product-specific and on the market, how the dismantling ofCritical metals are in great demand by the electrical and electronics industry, so waste electrical and eletronic equipment represents a significant source of secondary raw materials. Owing to low recycling rates and the concomitant supply risks associated with critical metals, the closure of the material cycles is highly relevant to the German economy. Losses of these metals occur from collection until their material recovery, along the entire disposal chain of waste electrical and electronic equipment. This paper develops planning criteria for the design of collection groups to achieve higher recovery amounts of such metals. The aim is to clarify what amounts of metals exist, both product-specific and on the market, how the dismantling of the products is constructed and how collection groups can be arranged with planning criteria oriented towards resource conservation. The analysis is a snapshot using the example of indium and selected products. A procedure is presented and findings identified which are transferable to various critical metals and to waste electrical and electronic equipment. The results show that grouping of products according to resource amounts and the dismantling effort enables forward-looking and resource-efficient planning of the treatment of every single collection group.show moreshow less
