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.
