目的 对退役叶片材料耐老化性能与风机叶片循环包装产品全生命周期内的碳足迹进行评价，以评价该工艺环保性能，并制定科学合理的碳减排方案来促进该产品的绿色发展。方法 本研究对风机叶片材料进行氙灯老化实验并测定老化前后材料静曲强度的变化，以评判产品寿命，并采用生命周期评价方法(LCA)，评估风机叶片循环包装的全生命周期中的碳足迹。结果 退役叶片主梁材料耐老化性能优良，符合循环包装产品设计要求。分析风机叶片循环包装托盘全生命周期内的碳足迹，产品运输是碳排放的主要环节，占比最大。风机叶片循环包装托盘虽然部分阶段碳排放量高于木质包装，但全生命周期中碳排放量更低。结论 风机叶片循环包装托盘环保效益显著，长期使用将有效减少包装行业中碳排放量，有利于我国环保事业的发展。运输过程中碳排放减少将有效降低产品全生命周期内的碳排放量，因此实现产品轻量化、模块化设计、采用新型环保材料和优化生产工艺将是减少循环包装产品温室气体排放的关键。

The work aims to evaluate the aging resistance of the material of decommissioned blades and the carbon footprint throughout the life cycle of the recycling packaging products for wind turbine blades, so as to assess the environmental performance of the process and formulate a scientific and reasonable carbon emission reduction plan to promote the green development of the product. The xenon lamp aging experiments were conducted on the material of the wind turbine blade and the changes in the static bending strength before and after aging were measured to judge the product life. The life cycle assessment method (LCA) was used to evaluate the carbon footprint in the entire life cycle of the recycling packaging of wind turbine blades. The main beam material of the decommissioned blade had excellent aging resistance, meeting the design requirements of the recycling packaging product. Through the analysis on the carbon footprint of the entire life cycle of the recycling packaging pallet for wind turbine blades, it was found that the product transportation was the main link of carbon emissions, accounting for the largest proportion. Although the carbon emissions of the recycling packaging pallet of wind turbine blades were higher than those of wooden packaging in some stages, the carbon emissions in the entire life cycle were lower. The environmental benefits of the recycling packaging pallet of wind turbine blades are significant, and the long-term use will effectively reduce carbon emissions in the packaging industry, which is beneficial to the development of China's environmental protection. Reducing carbon emissions in the transportation process will effectively reduce the carbon emissions in the entire life cycle of the product. Therefore, achieving the lightweight and modular design of products, adopting new environmentally friendly materials, and optimizing production processes will be the key to reducing greenhouse gas emissions from recycling packaging products.
