This review examines the role of wastewater treatment plants in retaining microplastics before they enter the environment. Studies show that no wastewater treatment method achieves complete microplastic removal, making treatment plants themselves point sources of microplastic discharge into aquatic environments. The review also discusses concerns about microplastic-laden sewage sludge being applied to agricultural land.

The emission of microplastics into nature poses a threat to aquatic and terrestrial ecosystems. Their penetration of the food chain presents a danger to human health as well. Wastewater treatment plants can be seen as the last barrier between microplastics and the environment. This review focuses on the impact of waste treatment plants in retaining microplastics. Studies show that no wastewater treatment method leads to a complete retention of microplastics, and so wastewater treatment plants themselves are viewed as point sources for the discharge of microplastics into the aquatic environment. Problems associated with the utilization of microplastic loaded sewage sludge are also discussed in the review.
