Environmental Risk Assessment of Non-Metallic Industries Using Combined PHA-William Fine Technique (Case Study: Eram Ardakan Tile Ceramic IND Co.)

Background: Non-metallic industries such as tile and ceramics, in addition to production and economic development, cause many environmental problems, including air and soil pollution and waste production. Industrial environments, by their very nature, are exposed to serious damage and hazards that are potentially expanding in line with the increasing growth of technology. This study was conducted with the aim of identifying and assessing the environmental risks of Eram Tile and Ceramic Industrial Company in Ardakan City by combined method of PHA and William Fine. Method: First, based on field visits to Eram Ardakan Company, environmental hazards were identified by PHA method and based on the work unit, performance of existing machinery, and human activities. Then, using the William Fine method, environmental risk assessment was performed and corrective solutions for high risks were presented. Results: Based on the findings of this study, 241 environmental hazards were identified, which were classified into 6 groups of environmental hazards (pollutants entering water, pollutants entering soil, pollutants entering air, loss of water and energy resources, generation of noise, and the generation and dispersion of industrial waste). The Risk Priority Number (RPN) of natural risks was 166, abnormal risks 52, and high risks 23. The highest RPN was 560 related to the operation of the crusher, spraying, operation of the furnace and dryer, press, and suction, while the lowest was 1, related to the excessive watering of trees and plants and uploading of animal manure. Conclusion: the assessment of hazards in the ceramics industry, while helping identify technical deficiencies and human errors, emphasizes the need for training and change the attitude of managers and personnel working in this industry and environmental inspections to maintain and promote environmental health.
