Abstract

The purpose of this study is to evaluate the environmental effects of SMF and GMF fluting paper production of Mazandaran Wood and Paper industries using the Life Cycle Assessment (LCA) method. Statistics and information required for this research were obtained through interviews with engineers and experts of the industries. The findings show that in section on the Life cycle inventory (LCI), the amount of water consumed and the emission of carbon dioxide have a greater share than other materials. Also, by examining the intermediate indices, it was found that among 15 groups of effects (carcinogenicity, non-carcinogenicity, mineral respiration, ionizing radiation, ozone depletion, organic respiration, aquatic toxicity, soil toxicity, soil acid/nutrient, occupation Earth, aquatic acidification, swamping, global warming, non-renewable energy and mineral extraction (aquatic toxicity category and non-renewable energy index) have the largest share. Findings from the assessment of damage in four categories of damage (human health, ecosystem quality, climate change and resources) show that the share of SMF fluting paper 155.08 percent and the share of GMF fluting paper 100 percent and the share Each is weighted in SMF 0.81pt and GMF 0.67pt. Also cumulative exergy demand in SMF fluting paper 38864.9 MJ and in GMF fluting paper 25873.53 MJ and the share of each in percentage in SMF fluting paper 150.21 percent and in GMF fluting paper 100 percent. The results showed that the production of GMF fluting paper has less environmental effects on the environment than the production of SMF fluting paper.
