MATERIALS HANDLING Scale-up of recycling may lower
the need for new mining activity by 25-40% by 2050 in a scenario that meets national climate pledges
the environmental and social ills that come from excessive mining.
TRADITIONAL METAL RECYCLING The report argues that scaling up the recycling of end-of-life scrap from traditional industries is essential to alleviate pressure on critical mineral supplies, particularly for copper since there is a supply defi cit. By 2035 announced projects will only be suff icient to meet 70% of copper requirements in the APS. However. opportunities to boost secondary copper supply are rising as scrap
volumes are likely to surge from around 2030. Copper scrap availability is expected to grow alongside consumption until then, when it will outpace demand growth. A combination of policies – raising collection rates for legacy applications, mandating recycling, improving sorting systems, and investing in new secondary smelters – can further elevate secondary supply’s contribution.
UNTAPPED POTENTIAL FROM MINE WASTE Mining generates around 100 billion tonnes of waste every year, in addition
to the sizeable amount already existing in active, inactive and closed tailings. The accumulated waste volume is set to increase by almost 90% over 2020 levels by 2030. Reprocessing mine waste, or tailings, can reduce waste generation and mitigate environmental impacts such as water contamination, safety risks and soil pollution. For closed or abandoned sites, it also presents an opportunity for environmental remediation. Previously, the minerals left in mine waste were considered economically unviable, but declining ore quality and future supply concerns are making reprocessing more appealing. For instance, in Chile, the copper content in mine waste with higher grades than primary sources is poised to rise from 1.6 Mt in 2005 to 5.6 Mt by 2050. Realising this potential will require comprehensive waste resource mapping, supporting research and development for new recovery technologies, providing economic incentives, and addressing liability barriers related to mine waste at closed sites.
