Abstract:
Effective environmental pollution should focus on management that can contribute to the development of the industrial business sector along with environmental sustainability. Cleaner technology is a tool to improve the production process or product in order to efficient resource utilization, to reduce pollution at its source and to reduce production cost. West Coast Engineering Co., Ltd. is a company that provides engineering services which are maintenance management in industrial plants, engineering design services, machinery and spare parts manufacturing, construction processing and installation of steel structures, piping systems, pressure vessels and industrial machinery. This research applied cleaner technology principles to adress the significant environmental aspect. According to this assessment, the highest significant aspect was the oil absorbent waste, which was highest disposal quantity of 39.09 tons in the year 2021. The analysis revealed the causes of this problem, which included: 1) Machinery leaks causing oil spill on the floor, 2) Large amount of cloth gloves and rags used without proper control. and 3) Absence of waste separation resulted mixed waste disposal. From these findings, the cleaner technology proposals were created and selected, assessing scores to prioritize the most appropriate recommendations based on four areas: technical, economic, environmental, and implementable. The results showed that the highest score was regular inspection of waste separation in each department. The second ranks score were 1) to control the consumption of cloth gloves and rags and 2) to conduct and to train the campaigns of waste separation in factories. Therefore, the factory implemented these proposals as they could immediately implemented and required no associated costs. After implementation, it was found that in the year 2022, cloth glove usage could be reduced by 9.74% compared to the sales volume, which was declined from the year 2021. The usage of rags decreased by 12.29% compared to the sales volume. This reduction in resource consumption corresponded with 57.42% reduction in oil absorbent waste sent for disposal, from 16.64 tons in 2021 which led to cost saving in waste management.
