Eco-Efficiency Assessment of Sustainable Wastewater Management Processes in Industrial Estates of the Eastern Region
Keywords:
Eco efficiency, Greenhouse gas, Wastewater, Reclaimed water, Life Cycle AssessmentAbstract
In the present, wastewater management in the industrial sector is primarily focused on the reuse of treated water. The purpose of this research is to study the efficiency of the biological wastewater treatment system under the operation of the industrial estate in Chonburi province. The Industrial Estate, under the supervision of the Industrial Estate Authority of Thailand, is aware of Sustainable Development Goals (SDGs), particularly Goal 6. SDG 6 aims to ensure availability and sustainable management of water and sanitation for all, according to the United Nations. The Industrial Estate integrates environmental tools in line with the concept of a circular economy, with a focus on minimizing environmental impacts. Minimizing water consumption, reducing pollution, and cutting down on management expenses are integrated into industrial estates. OpenLCA is software designed for evaluating the life cycle of products and eco-efficiency. The environmental impact assessment includes effects on Human Health, Ecosystem Quality, and Resources, with values of 3.36E-05 DALY, 9.07E+03 PDF.m2.yr, and 2.54E+05 MJ, respectively. The Eco-Efficiency index is precisely 65.23. The reutilization of treated water reduces 34.08% in greenhouse gas emissions. Industrial estates can achieve reduction in expenses and a decrease in carbon dioxide emissions.
