目的 通过量化分析以竹纤维和甘蔗纤维为原料的纸浆模塑眼镜盒的全生命周期环境影响，识别其生产过程中的最相关生命周期阶段和过程，并提出改进建议。方法 基于欧盟产品环境足迹方法，利用SimaPro软件和Ecoinvent数据库对眼镜盒进行生命周期建模，采用EF 3.1方法量化其潜在的环境足迹，并进行生命周期解释和分析。结果 气候变化、化石资源利用、颗粒物、酸化和光化学臭氧形成是纸浆模塑眼镜盒生产过程中的最相关环境影响类别。生产1 000 kg纸浆模塑眼镜盒造成的气候变化影响为6 164.25 kg CO2 eq.，主要与浆板制造和制品成型过程中的电能、蒸汽能源消耗密切相关。采用清洁能源替代传统电能，最多可减少生产过程中80%的温室气体排放。相较于完全焚烧、填埋，废弃物回收后纸浆模塑眼镜盒的气候变化影响可降低8.78%~20.11%。结论 减少生产过程中的电能消耗、加速清洁能源的转型和纸浆模塑废弃物回收体系的构建，可减少其环境足迹，促进纸浆模塑的可持续发展。

The work aims to identify the most relevant life cycle stages and processes in the production process of the pulp molding eyeglass case made from bamboo and sugarcane fibers by quantifying the environmental impact of the whole life cycle and make suggestions for improvement. Based on the EU product environmental footprint method, SimaPro software and Ecoinvent database were used to model the life cycle of the eyeglass case, EF 3.1 method was employed to quantify the potential environmental footprint, and life cycle interpretation and analysis were conducted. Climate change, fossil resource utilization, particulate matter, acidification and photochemical ozone formation were the most relevant environmental effects in the production of the pulp molding eyeglass case. The result of climate change caused by the production of 1 000 kg pulp molding eyeglass case was 6164.25 kg CO2 eq., which was mainly related to the electricity and steam consumption in the pulp board manufacturing and product molding process. Replacing conventional electricity with clean energy could reduce greenhouse gas emissions by up to 80% during production. Compared with complete incineration and landfilling, the climate change impact of recycled pulp molding eyeglass case could be reduced by 8.78%-20.11%. Reducing the power consumption in the production process, accelerating the transformation of clean energy and constructing the recycling system of pulp molding waste can reduce the environmental footprint and promote the sustainable development of pulp molding.
