Cleaner production: a case study of Kaveh paper mill

Abstract

The pulp and paper industry is under increasing pressure to reduce its energy consumption and impact on the environment. The ‘Cleaner Production’ (CP) approach has been widely utilised as a tool to meet environmental concerns by industry. However, because of the high initial capital cost of CP implementation, it is important to develop a model for prioritisation. In this paper, using analytic hierarchy process methodology, a tree-level hierarchy model was structured to facilitate the prioritisation process in the Kaveh Papermaking Company located in Iran. Using a literature review and field study, the proposed model can provide a framework for CP implementation in a paper factory. The results show that process change gives higher priority between 5 criteria and that repair of all leaks in the paper-making process gives higher priority between 35 sub-criteria. Process change was further evaluated and discussed in which input material changes gained higher priority. The results of this research can be used to accelerate the implementation of CP in Iran's pulp and paper industry.
