    摘要:

    为了比较源于淀粉和纤维素替代材料的环境绩效,以餐饮外卖领域推广使用的生物基餐具(复合淀粉基材料、覆膜纤维基材料)与可降解塑料餐具(全淀粉材料、全纤维材料)为研究对象,分析产品生命周期中的各种资源、能源消耗和环境排放并评价其环境影响。以1 000个外卖食品餐盒为基准流,利用环境评估软件建立绿色环保餐具的生命周期评价LCA模型。结果表明,源于淀粉的绿色餐盒碳排放和能量消耗主要集中于原料获取和废弃物处理两个阶段,源于纤维的绿色餐盒碳排放和能量消耗则主要集中在制品生产阶段。全淀粉可降解餐具的各项环境影响指标最低,其中累计释放CO2 39.91 kg,消耗电能332.04 MJ,较全纤维可降解餐盒碳排放降低69.5%,节约电能416.23 MJ。

    Abstract:

    In order to compare from the environmental performance of starch and cellulose material,this thesis to popularize the use of the biological basis of takeout areas catering utensils (compound starch material coated fiber wiki) and biodegradable plastic tableware (total starch materials All fiber) as the research object,analysis of the product life cycle energy consumption and environmental emissions of various resources and evaluate its environmental impact Flow based on 1 000 take-out lunch box,environmental assessment software is used to establish the green environmental protection tableware of LCA in life cycle assessment model results show that the carbon emissions and energy consumption is the result of starch green boxes which focuses on raw material acquisition and the two stages of waste disposal,green boxes from the fiber carbon emissions and energy consumption is mainly in the products production stage The total starch degradable tableware has the lowest environmental impact index,in which the cumulative CO2 release is 39.91 kg and the energy consumption is 332.04 MJ.Compared with the total fiber degradable meal box,the carbon emission is reduced by 69.5% and the energy saving is 416.23 MJ.
