Abstract :
In this paper, the indexes system of green degree of biodegradable packaging materials is built and the Fuzzy Analytical Hierarchy Process (FAHP) methodology based on Life Cycle Assessment (LCA) is employed to analyze and assess this system. The qualitative assessment is gained by the survey and the statistics theory is employed to deal with the qualitative data. The judgment matrix is built and the maximum characteristic root and vector are computed by the sum and product method. Then the relative importance degree of every influence factor is computed and the comprehensive importance degree of every influence factor is gained. The membership function of every influence factor is established by logical reasoning assignment method, then the membership degree is gained. According to the comprehensive importance degree and the membership degree of every influence factors, the green degree of biodegradable packaging materials is generally assessed. The green degree of biodegradable packaging materials is compared with that of plastic material, and the result is that the biodegradable packing materials have higher green degree then that of plastic material.
