Abstract

Abstract

Against the backdrop of deepening global green transition and tightening resource and environmental constraints， China advances Zero-Waste City construction under the Dual Carbon Goals， taking waste resource utilization as a critical pathway for sustainable development. As an essential basic metal for the national economy， zinc faces challenges such as high external dependence and an approaching primary resource exploitation threshold， making the regenerated zinc industry a core force to bridge the resource gap. However， Regenerated Zinc Raw Material（YS/T 1093—2015） has become outdated in its classification system， technical indicators， and environmental requirements， failing to adapt to industrial upgrading and the increasingly complex composition of raw materials. This paper focuses on YS/T 1093—2024， analyzing its revision background， core content， and impacts along the industrial chain. The revision renames the standard and clarifies its nature as front-end smelting intermediate feedstock. The new standard establishes a classification system covering six typical zinc-bearing materials （with expanded utilization of low-grade complex materials）， tightens limits on harmful elements （fluorine， chlorine， lead， etc.）， and adds practical indicators （moisture control， appearance evaluation）， enhancing operability and guidance. Compared with EU standards， it shows systematic improvements in raw material coverage， process adaptability and environmental risk control. Moreover， this paper discusses the standard’s implementation path and optimization directions from three dimensions： old-new comparison， practical industrial suggestions， and international alignment. Its implementation is expected to drive the regenerated zinc industry towards intensification， high-value utilization and clean production， improving resource recycling efficiency， reducing environmental pressure， and supporting China's zinc resource strategic security and low-carbon development.
