ClearEradicating microplastics in wastewater: microalgae as a sustainable strategy
This review examines the use of microalgae as a sustainable strategy for removing microplastics from wastewater, discussing biosorption mechanisms, removal efficiencies, and the limitations of conventional treatment plants that typically achieve only up to 90% MP removal.
Efficiency of Microalgae Employment in Nutrient Removal (Nitrogen and Phosphorous) from Municipal Wastewater
This review examines how microalgae (tiny aquatic plants) can be used to remove nitrogen and phosphorus pollutants from municipal wastewater. While not directly about microplastics, this research is relevant because effective wastewater treatment is one way to reduce the amount of microplastics that reach waterways and eventually the food chain.
Interplay of plastic pollution with algae and plants: hidden danger or a blessing?
Researchers tested the ability of three microalgae species to remove microplastics from water through bioadhesion, finding that all three species could adsorb particles onto their surfaces. Removal efficiency depended on particle size, surface charge, and algae cell morphology.
Are algae a promising ecofriendly approach to micro/nanoplastic remediation?
This review examines the potential of algae as an eco-friendly approach to removing micro- and nanoplastics from wastewater treatment plant effluents, covering mechanisms including interception, entanglement, and heteroaggregation. Algae also offer the added benefit of nutrient recovery from wastewater and can be further processed into biochar or biofertilizer.

Remediation and upcycling of microplastics by algae with wastewater nutrient removal and bioproduction potential
Researchers demonstrated that algae can simultaneously remediate microplastics from water and remove nutrients like nitrogen and phosphorus from wastewater, while also producing valuable biomass, presenting an integrated and sustainable platform that converts plastic waste into a resource.
Influence of microplastics on microalgal performance during wastewater polishing
Researchers studied how five common types of microplastics affect the green alga Chlorella vulgaris during wastewater treatment. They found that while microplastics reduced algal metabolism and growth, the organism maintained its ability to effectively remove nutrients from wastewater. The study demonstrates that Chlorella vulgaris is a robust candidate for bioremediation of microplastic-contaminated wastewater, even under pollutant stress.

Researchers investigated interactions between microplastics, model pesticides, and microalgae in wastewater treatment systems, examining how the co-presence of microplastic particles and pesticide contaminants affects the efficiency of microalgae-based treatment for removing nitrogen and phosphorus from wastewater intended for agricultural reuse.
Optimization of microplastic removal based on the complementarity of constructed wetland and microalgal-based system
This review examines how constructed wetlands and microalgal-based systems can each remove microplastics from wastewater, along with the limitations of using either approach alone. Researchers found that microplastic accumulation can block wetland substrates and inhibit nitrogen removal, while microalgae face separation challenges in effluent. The study proposes combining both biotechnologies to expand the size range of microplastics removed and improve long-term wastewater treatment sustainability.
