“…Many chemical wastewaters are highly toxic (Li et al., 2011), difficult to purify and accumulate in organisms (Nasr et al., 2005). Thus, the appropriate control of wastewater treatment plants (WWTPs) in individual manufacturers and of the centralized WWTPs in parks can reduce organic pollutants, nutrients, and heavy metal pollutants (Chen et al., 2017; Lyu et al., 2020). The two‐stage wastewater treatment system, that is, an in‐plant WWTP followed by a centralized wastewater treatment plant (CWWTP), has been widely employed in Chinese IPs (Hu et al., 2019).…”

“…These result in negative environmental impacts and may offset the positive benefits of reducing wastewater pollutants (Wang et al., 2015; Zeng & Chen, 2016). Moreover, the Chinese government is requesting IPs to improve their environmental management, featuring (1) the implementation of much stricter and more transparent pollution control by continuously raising pollution discharge standards and (2) the application of systematic optimization from the perspective of life cycle thinking (Ma et al, 2019). Due to the mandatory improvement of the emission limits of the CWWTPs in China (Lyu et al., 2020), the enhancement of the end of pipe treatment in individual enterprises is inevitable.…”

In light of the complexity of pollutants and multiple wastewater treatment processes in CIPs, a comprehensive and quantitative evaluation of the wastewater treatment system of CIPs is necessary targeting systematic analysis for the more stringent than ever emission limits in the coming years.…”

As the most important production space for the development of chemical industry in China, chemical industrial parks (CIPs) are facing a new challenge of water pollution prevention and control, in addition to those posed by traditional and emerging pollutants. It is thus important to systematically reveal the compositewater‐environmental impact of CIPs for contributing to the sustainable development of the chemical industry. CIPs have the issue of intensive wastewater generation characterized by complex pollutant components and high pollution loads. Thus, establishing an environmentally friendly wastewater treatment system has always been a major challenge for CIPs. China has developed many CIPs and the two‐stage wastewater treatment system is widely employed in practice, that is, in‐plant wastewater treatment plants (WWTPs) in individual enterprises followed by centralized WWTPs in parks. Since the CIP wastewater emission limits are continuously improved, a comprehensive evaluation of the environmental impacts of the in‐use wastewater treatment system will be insightful for future policy making. This study employed life cycle assessment (LCA) to reveal the life cycle environmental impact of the two‐stage wastewater treatment system in a typical CIP. We found that the life cycle environmental impacts of the whole system mainly stem from the in‐plant WWTPs of chemical manufacturers because of chemicals and electricity consumed in the multi‐stage advanced oxidation technologies, while the increase of human toxicity potential and marine aquatic ecotoxicity potential are primarily due to sludge incineration. Three scenarios targeting the reduction of environmental impacts were proposed based on the LCA results. We evaluated the pollution mitigation potential, which can reach at most 8% of the original measured impacts. Finally, from the perspective of systematic thinking, four policy implications for improving the water management system of CIPs were proposed.

“…They found that the economy of scale associated with the capacity of treatment plant influences the cost of wastewater treatment. While using a life cycle costing method for the wastewater treatment plant of a chemical park of Hangzhou, China, Lyu et al (2020) found that the cost of the plant amounted to around 29% of the revenue of the park. Talang et al (2020) also performed life cycle assessment (LCA) and life cycle cost assessment for municipal wastewater treatment in Bangkok, Thailand, to analyse the environmental impacts and cost-effectiveness, respectively.…”

PurposeIt has been long debated whether the three bottom lines of sustainability (economic, environmental and social) can be achieved simultaneously or whether achieving one adversely affects the others. This paper analyses the economic sustainability of an environmental initiative, namely, effluent treatment plant (ETP), adopted by an Indian textile industry.Design/methodology/approachTwo situations have been considered for the analysis. First, pure economic view with the operating and installed capacities has been considered. Second, combined economic-environmental view using shadow prices of undesirable outputs (biological oxygen demand, chemical oxygen demand, total nitrogen, total phosphorous, etc.) has been analysed.FindingsIt has been found that when pure economic view is considered, the net present value (NPV) of the ETP with present operating capacity (10,200 kL/day) is negative, implying that it is not economically sustainable. However, if the ETP is operated with the full installed capacity (17,000 kL/day), it becomes economically sustainable except in the case of very high cost of capital (13%). Finally, when shadow prices of undesirable outputs are considered, the NPV becomes positive, bolstering the economic-environmental sustainability of ETP.Research limitations/implicationsIn future, multiple case studies should be conducted in similar organisations to extend the general applicability of the outcome of this study. This research considers the economic and environmental aspects of ETP. However, social benefits have not been considered in this research work, which can definitely be addressed in future endeavours.Practical implicationsThough very high capital investment of ETP acts as a barrier, the results of this study imply that the top management of textile and clothing organisations should look at it from the holistic economic-environmental viewpoint. The use of ETP also leads to social benefits by improving the health of local community and by reducing their hospitalisation, medical expenditure and absenteeism from school and workplace. The outcome of this research may enthuse the entrepreneurs to adopt environmental initiatives.Originality/valueThe paper provides a framework to evaluate the economic feasibility of ETP by considering the time value of money. It is demonstrated with a real case that the environmental initiatives can be economically rewarding.
