关键矿物的回收利用扩大回收和城市采矿的战略（英）2024

Investment Rating - The report emphasizes the critical importance of recycling in ensuring the security and sustainability of critical minerals supply for clean energy transitions, indicating a positive outlook for investments in recycling infrastructure and technologies [3][13][14]. Core Insights - Recycling is essential for reducing reliance on new mining and enhancing supply security for countries importing minerals, while also mitigating environmental and social impacts associated with mining [3][13][19]. - The report outlines significant potential for recycling to lower the need for new mining activities by 25-40% by 2050, particularly for copper and cobalt [19][20]. - The market value of recycled energy transition minerals is projected to grow fivefold, reaching USD 200 billion by 2050, highlighting the financial benefits of enhanced recycling efforts [19][20]. Summary by Sections Executive Summary - Recycling is indispensable for the security and sustainability of critical minerals supply, especially as the shift to clean energy accelerates [13][14]. - Substantial investments in recycling infrastructure can help build reserves to buffer against future supply disruptions [13][14]. Introduction - The transition to clean energy technologies requires more minerals than fossil fuels, creating potential supply-side strains [59][60]. - Recycling can provide a secondary source of supply, reducing the burden on primary supply from new mines [63]. Scenarios - The report employs three main scenarios to explore different energy pathways to 2050, including the Net Zero Emissions by 2050 (NZE) Scenario, Announced Pledges Scenario (APS), and Stated Policies Scenario (STEPS) [74][76][78]. Chapter 1: State of Play - The report assesses the current status of recycling, including how recycling works, performance indicators, and recent policy developments [11][1][4]. Chapter 2: Outlook for Critical Minerals Recycling - The potential for secondary supply from recycling is analyzed, with specific focus on battery metals, copper, and rare earth elements [2][2][2]. Chapter 3: Cross-Cutting Issues - The report discusses the economics of recycling, technology innovation, and sustainability considerations that can maximize recycling potential [3][3][3]. Chapter 4: Policy Recommendations - Key policy recommendations include developing long-term policy roadmaps, harmonizing waste management policies, and strengthening domestic recycling infrastructure [52][54][56].
