Innovative Solutions for Soil Remediation from Microplastics Pollution
Summary
This book chapter surveys innovative remediation approaches for removing microplastics from contaminated soils, covering physical, chemical, and biological methods as well as novel technologies including nanomaterial-based adsorbents and electrochemical systems.
The pervasive issue of microplastic (MP) pollution in soils poses a significant environmental challenge, demanding innovative and effective remediation solutions. Microplastics, ubiquitous in soil ecosystems due to various sources, present severe threats to soil health, plant growth, and overall ecosystem vitality. This chapter presents an exploration of innovative strategies for soil remediation targeting MPs. The chapter encapsulates various approaches and technologies, including physico-chemical (advanced soil washing, electrokinetic remediation, centrifugation, and ultraviolet radiation) and biochemical (use of surfactants, enzymatic treatment, phytoremediation, bioaugmentation, or addition of high sorption (nano)materials) methods, highlighting their efficacy and limitations. The insights provided in this chapter are pivotal for guiding future research endeavors towards the development of sustainable and scalable solutions to alleviate the adverse impacts of MPs on soil ecosystems.
