Life Cycle and Techno‐Economic Assessment of Microplastics Remediation Technologies and Policies
Summary
This chapter analyzes microplastic remediation technologies using life cycle assessment, techno-economic assessment, and SWOT analysis to compare their sustainability and cost-effectiveness. Researchers evaluated methods such as froth flotation, density separation, and electrostatic separation for removing microplastics from water. The study aims to help researchers understand which remediation approaches are most technologically and economically feasible without compromising environmental sustainability.
The life cycle assessment (LCA) tool aids in determining the environmental performance and impacts caused during the entire process of microplastic (MP) remediation involving physical, chemical, biological, or hybrid methods. The LCA is a prevalent tool to critically compare the existing treatment methods so as to weigh them based on sustainability and environmental compatibility. Thus, this book chapter delves into analyzing the different MP remediation methods by utilizing tools such as techno-economic assessment (TEA), LCA, and strength-weakness-opportunity-threat (SWOT) analysis. Moreover, the TEA and cost–benefit ratio provide insights into the economic efficiency of various MP remedial methods, such as froth flotation, density separation, and electrostatic separation of MPs from water matrices. Additionally, the technological efficiency of various existing MP remedial methods and their potential social impacts on the health and well-being of living organisms are also elucidated. Nevertheless, this chapter will aid researchers in understanding the technological and economic feasibility of MP remediation methods, without compromising on the grounds of sustainability.
