Abstract ：
Decarbonizing the iron and steelmaking industry is critical for China to pursue the net-zero emissions target and advance sustainable industrialization (SDG 9). This paper addresses the urgent need for decarbonization strategies in this sector, aiming to align with China's carbon neutrality goals by 2060. By reviewing the current technological advancements and potential pathways for deep decarbonization, including process optimization, hydrogen-based direct reduction, and carbon capture, utilization, and storage (CCUS), these decarbonization technologies are categorized into six strategic approaches: systemic energy efficiency improvement, resource recycling, process optimization and innovation, breakthrough smelting, product iterative upgrading, and CCUS. These strategies also align with SDG 13 (climate action) by reducing greenhouse gas emissions and SDG 7 (affordable and clean energy) through the promotion of clean energy technologies. These strategies are evaluated for their emission reduction potential and technological maturity. The results indicate that, while efficiency improvements and resource recycling are currently the most mature and widely implemented strategy, significant breakthroughs in hydrogen metallurgy and CCUS are essential for achieving long-term carbon neutrality. Based on an analysis, a comprehensive roadmap is proposed, detailing the near-term to long-term actions required for the industry's transition. The near-term focus (up to 2030) should be on enhancing energy efficiency and process optimization, whereas the mid-term (2030-2050) focus should emphasize the adoption of hydrogen-based technologies and CCUS. By the 2050-2060 period, the industry should achieve widespread commercialization of breakthrough smelting technologies and CCUS, ensuring the achievement of carbon neutrality. This study intends to provide a systematic framework and strategic recommendations for policymakers and industry stakeholders to guide the decarbonization of China's iron and steelmaking sector, addressing both technological and economic challenges to achieve sustainable and low-carbon development.

Abstract ：
The emission of chlorinated pollutants is one of the main problems when recovering copper (Cu) via pyrolysis from waste enameled wires. This is mainly attributed to other wastes which possess high poly(vinyl chloride) content, such as electrical wires and cables, which are often recycled together with enameled copper wires. In this research, to control the chlorinated pollutants, copper(II) oxide (CuO) was chosen and demonstrated to be an efficient dechlorinating agent, and CuO did not introduce any impurities that influence the quality of the recovered Cu. The pyrolysis and co-pyrolysis of polyester enameled wires, PVC, and CuO were investigated, and special attention was paid to chlorinated compounds in released pyrolytic products. In particular, the co-pyrolysis of this ternary mixture was studied for the first time, and some new pyrolysis behaviors were discovered. For example, the results of Py-GC/MS analyses showed that the addition of CuO removed about 75% of the chloro-organic products, the main types of which were chloroaromatic compounds rather than the more toxic chloroesters. Moreover, pyrolysis gases were collected and characterized via ion chromatography, and the results showed that the chlorine content in the pyrolysis gases decreased by about 71%. TG analysis indicated that CuO only minimally affected the pyrolysis of polyester paint. However, through the chlorine fixation effect, CuO influenced the dechlorination and dehydrochlorination of PVC, as well as secondary reactions between HCl and pyrolysis products of polyester paint, therefore changing the products and behaviors of co-pyrolysis. Mechanism of reducing chlorine-containing pollutants and reaction mechanism of forming typical pyrolysis products closely correlated to the effects of CuO were also proposed, providing theoretical guidance for the recycling of waste enameled wires.

Abstract ：
Offshore wind power contributes to the decarbonization of the power system; however, its green development faces many challenges, including environmental impact concerns, scale limitations, and grid parity to go carbon neutral. This study applies life cycle assessment (LCA) to evaluate the potential environmental impact of China's first high-power prototype windfarm. The environmental impact of the wind farm is more sensitive to steel, copper, and electricity usage. The recycling of waste turbines can be a solution to reduce the environmental impacts of not only the wind farm but also other entities such as metal producers. Overall, this wind farm case can reduce energy consumption and greenhouse gas emissions by 9.23 MJ and 767.9 g CO2-eq for 1 kWh electricity produced, respectively. Guided by LCA results, green development strategies that include toward the deep sea, promote industrial upgrading and synergy, and advance demonstration projects are discussed in the offshore wind power industry.

Abstract ：
LiCoO2 (LCO) lithium-ion battery (LIB) is rich in valuable metals (cobalt and lithium), which has high recycling value. The existing process has basically realized the extraction of cobalt, but there are still shortcomings in harmless disposal of fluorine-containing electrolyte, binder and other organic matters, selective extraction of lithium and low-cost extraction of cobalt. In this context, a novel process was developed to realize the full-component recovery of spent LiCoO2 battery via environmentally friendly pyrolysis and hydrometallurgical leaching. The organic matters were recovered in the form of pyrolytic oil and gas, in which the harmful fluorine element was absorbed by Ca(OH)(2) solution. The current collectors (copper and aluminum) were recovered after the easy separation of electrode materials due to the degradation of binders. During pyrolysis the cathode material was deconstructed and reduced under the synergistic effect of pyrolytic gas and anode graphite. Selective recovery of lithium and cobalt was achieved through carbonated water leaching and reductant-free acid leaching. The leaching efficiencies of lithium and cobalt were respectively 87.9% and 99.1% under the optimal conditions. Lithium carbonate and cobalt sulfate were obtained by evaporative crystallization, respectively. The remaining residue was only graphite without impurity entrainment. The results in this research suggest that the process consisting of pyrolysis and hydrometallurgical leaching is inexpensive, efficient, and eco-friendly for full-component recycling of spent LiCoO2 battery.
