YOU Wu1,XU Li-zhong1,PAN Ya-bin2(1.Institute of Environmental Science,Fujian Normal University,Fuzhou 350007,China; 2.Minnan Institute of Science and Technology,Fujian Normal University,Quanzhou 362300,China)  
Life cycle assessment combining entropy-weighted osculating value method was employed to evaluate environmental friendly properties of six binds of disposable fast food containers,i.e.pulp,starch-based plastics,foam plastic,non-foam plastic,microbial-blended material and microbial-synthesis material.The quantitative analysis based on entropy weight showed that: divergence among these six materials were mainly in production process expressed as pollutant emission and resource consumption,especially water consumption,wood consumption,and BOD and organochlorine discharge.Microbial-blended and microbial-synthesis materials.were of the least resource and environment load,pulp,however,whose environmental friendly was worse than plastics were the worst one among the six materials.Our result may be a help for consumer to reconsider their consuming behavior.
