Determination and ranking cleaner production criteria by using analytic hierarchy process (Case study: Latif paper products company)

Cleaner production process is an environmentally friendly approach that attempts to reduce waste and energy consumption then reduce environmental pollutions of industrial processes to provide the possibility of sustainable production in industrial units. To achieve this goal and alignment with cleaner production strategies, paper industries should consider reducing wastes of production processes and irregular consumption of energy as a priority in their programs. In this research Analytic Hierarchy Process has been applied and a three level hierarchy model was structured to facilitate the cleaner production process in Latif paper products firm. Using a literature review and field study, the proposed model provided a framework for cleaner production implementation in the firm. Results showed priorities of the main criteria of cleaner production are process change, product modification, implementation of preventive maintenance system, resititution and man force capitals respectively. Process change criterion allocated 40 percent of the total weighing value and has the highest priority in implementation of cleaner production strategy. Existence of industrial automation and its technology level which is a sub criterion of process change has the highest priority among 31 sub criteria. Also some of higher priority sub criteria such as use of higher quality inclusion and implementation of calibration system are related to process change. Therefore, to achieve cleaner production goals and implementation of its strategic objectives it is necessary to pay more attention to this criterion. Inconsistency ratio of the research is 0.06 which indicates the results are compatible. The results of this research can be used to accelerate the implementation of cleaner production process in Iran’s pulp and paper industry.
