Fig. 1 shows an overview of copper flows in 2018. Overall copper demand was 29.1 Mt for the production of semi-finished copper products. While the global mine production covered 20.9 Mt, recycling of copper from fabrication scrap as well as end-of-life (EoL) products provided 8.7 Mt and thereby covered 30% of the global demand.Web

For example, the U.S. metal scrap recycling industry has increased by 37% from $77 billion in 2010 to $106 billion in 2015 (ISRI, 2016). Another strong economic incentive for recycling is a study by Johnson et al. (2007) which found that most metals currently targeted for recycling have post-disassembly concentrations that are more …Web
