According to its specific energy consumption, the industrial processes can be classified into three groups; the processes which uniformly and continuously consumed energy, the process which unevenly consumed energy according to production cycle and the processes which combined both types of energy consumption. Key words : plastic products industry, energy efficiency, industrial classification, industrial process, specific energy consumption
