Evaluation of Iranian Recycling Industries

Today, the rapid increase of the industrial activities and uncontrolled consumption of natural resources caused environmental problems. Recycling as a prominent strategy paved the way for developing recycling industries. Current research evaluated Iranian recycling industries according to Iranian industries organization database. By the way, six different types of recycling industries were evaluated based on technical, financial, input initial materials and energy consumptions via statistical methods. Iranian recycling industries include blown bitumen, plastic wastes, used motor oil and grease, oil filter, agricultural wastes recycling to cardboard and recycling silver of radiology films and its solution. The paired test analysis revealed significant differences between power-water and fuel-land among parameters such as initial feed, employees, power, water, fuel and land for 6 types of recycling industries (pvalue ≤ 0.016 and 0.023) respectively. Also, paired sample correlation analysis presented values of around 0.00 and 0.022 between both groups of plastic wastes recycling and recycling silver from radiology films and its solution and oil filter and motor oil and grease industries respectively. Also, it was found the highest values of about 0.99 between agricultural waste recycling to cardboard and plastic waste recycling industries by Pearson correlation analysis. The evaluation manifested the values of around (0.46), (1), (1.51), (1.06), (0.99) and (1.32) for initial feed, employees, power, water, fuel and land via max Z procedure respectively.
