Abstract: On the basis of analyzing the policy development of recycled cast aluminum alloy, the industry development overview and the implementation effect of the standard, the old and new standards of GB / T 38472 are compared from the perspectives of classification difference and technical difference. Based on the main technical changes of the new version of the standard, the countermeasures and suggestions such as strengthening the publicity and implementation of the new standard, carrying out the standardization pilot demonstration, promoting the reuse process upgrading, and creating a social reuse atmosphere are put forward to help the comprehensive implementation of the new standard.
Keywords: reclaimed cast aluminum alloy; national standard; standard comparison; circular economy
1再生鑄造鋁合金行業(yè)概況
1.1再生鑄造鋁合金行業(yè)相關政策
2020年4月,歐洲鋁業(yè)協(xié)會宣布啟動“再生鋁行動計劃”,力爭到2050年再生鋁占到鋁供應量的50%,替代高碳排放的進口原鋁,以達到在降低進口鋁依賴度的同時降低碳排放46%的目的。(剩余4290字)
