Green rationality evaluation of degradable packaging based on LCA and fuzzy AHP

According to the basic principle of product life cycle analysis, this paper establishes an evaluating index system of green rationality from tripartite surfaces: the environmental factor, the resource factor and economic factor, then defines the weight coefficient for each index by AHP, and gives a fuzzy comprehensive evaluation of green rationality. Finally an example that evaluates the green rationality of paper and biomass packaging materials, is given to show the use of the method, and concludes that biomass packaging material has higher degree of green rationality. The result reveals that application of Fuzzy AHP to evaluate the green rationality can consider numerous factors, establish a relatively comprehensive evaluation system, and offer some suggestions for the future research trends of packaging materials´ improvement.
