Managing Environmental Aspects and Impacts of Pulp and Paper Industries using Analytical Hierarchy Process (AHP)

In this study, managing environmental aspects of pulp and paper industries using AHP method was studied. The process of producing paper have 4 main step that done in for main unit of paper factories, the unit of Preparation and production of wood, pulp production unit, paper production unit ,chemical recovery system unit .
To identify and manage environmental aspects and environmental impacts of the industry AHP method (Analytical Hierarchy Process) was used. In the hierarchical structure of research, Factory production units were selected as criteria and various activities of each unit were selected as sub-criteria, four major environmental impact of the factory were selected as alternatives (water pollution, air pollution, noise pollution and solid waste pollution).
After analyzing the hierarchy with a group of experts in the software Expert Choice, four important results was obtained. 1- Most important environmental impacts of Wood and Paper industries 2- Which of the factory's production unit makes the most contaminants 3- in every single unit, which are most significant environmental aspects. 4- Any trace of contamination was identified that are shown in graphs .finally the obvious causes and effects of each of the significant aspects were examined and some solutions were presented in order to fix them.
