摘要

中国是全球光伏产业的领导者,也将面临光伏产品报废潮带来的巨大挑战。构建有效的回收体系对于退役光伏产品的管理至关重要。本研究利用 Stackelberg 博弈论,建立并比较了三种退役光伏产品回收模式,包括制造商回收、第三方回收和生产者责任组织(PRO)回收。随后,模拟分析了组件处理成本、梯队利用率和回收补贴对各种回收模式的转让价格、回收数量、供应链利润和碳排放的影响。结果表明(1) 制造商回收实现了最佳供应链利润;(2) 与专业回收模式相比,当退役组件加工成本低于特定阈值时,第三方回收具有更优越的性能;(3) 在降低组件加工成本的同时,提高梯队利用率和回收补贴可以补充光伏闭环供应链(CLSC)的整体经济和环境效益;(4) 不同回收模式的环境性能与碳减排效率相关。因此,本文为制造商、回收商和政府开发可持续的退役光伏产品回收系统提供了有价值的见解。

Comparative evaluation of different recycling modes for decommissioned photovoltaic products based on stackelberg game.

China is the photovoltaic (PV) leader worldwide and will be confronted with significant challenges stemming from the scrap tide of PV products. Constructing an effective recycling system is essential for retired PV product management. Using the Stackelberg game theory, this study establishes and compares three recycling modes including manufacturer recycling, third-party recycling, and producer responsibility organization (PRO) recycling for decommissioned PV products. Afterward, the effects of module processing costs, echelon utilization rates, and collection subsidies on the transfer prices, collection quantities, supply chain profits, and carbon emissions of the various recycling modes are simulated and analyzed. The results reveal that: (1) The manufacturer recycling realizes optimal supply chain profits; (2) Compared to the PRO recycling mode, the third-party recycling experiences superior performances when retired module processing costs are lower than a specific threshold; (3) Uplifting echelon utilization rates and collection subsidies while reducing module processing costs could supplement the overall economic and environmental benefits within the PV closed-loop supply chain (CLSC); (4) Environmental performances of the different recycling modes are associated with the carbon emission reduction efficiency. Accordingly, valuable insights are provided for manufacturers, recyclers, and governments to develop a sustainable retired PV product recycling system.
