使用SimaPro软件和Ecoinvent数据库对纸浆模塑天地盖礼盒生产的生命周期进行建模，采用EF 3。0方法对生命周期进行环境影响分析，量化和识别其生产过程中的主要环境足迹及其贡献过程，并解释其环境影响。结果表明:生产一万套纸浆模塑天地盖礼盒造成的气候变化影响为7609。27 kg CO2 eq。，其中由化石资源引起的碳排放为7591。24 kg CO2 eq。。在纸浆模塑礼盒生产过程中，气候变化、化石资源消耗、颗粒物、酸化和光化学臭氧形成是主要的环境影响类别，累积贡献超过了整体环境影响的80％。热压整形过程中电能消耗是引起环境问题的主要原因。通过敏感性分析可知，减少生产过程中的电能消耗量或者使用清洁能源，最多可减少约95％的碳足迹，并降低整体环境影响。
Environmental Impact Analysis of Pulp Molding Gift Boxes Based on Life Cycle Assessment
SimaPro software and the Ecoinvent database were used to model the life cycle of pulp molding gift box production,and the EF 3.0 method was used to analyze the environmental impacts of life cycle,to quantify and identify the environmental footprints of the production process and its contributing processes,and to assess and explain its environmental impacts.The results show that the climate change impacts caused by the production of 10 000 sets of pulp molding gift boxes is 7609.27 kg CO2 eq.,with 7591.24 kg CO2 eq.caused by fossil resources.Climate change,fossil resource depletion,particulate emissions,acidification,and photochemical ozone formation are the main environmental impact categories in the production process of pulp molding gift boxes,with a cumulative contribution of more than 80％of the overall environmental impacts,among which,the thermo-compression shaping process and its electrical energy consumption are the main causes of environmental problems.Through sensitivity analysis of the results,reducing the amount of electrical energy consumed in the production process or using cleaner energy alternatives could reduce the carbon footprint by up to about 95％and lower the overall environmental impact.
