ClearPotential for Using Algae to Reduce Microplastics in the Environment
This review described how algae can reduce microplastic pollution through two mechanisms: physical adsorption and entrapment of particles into aggregates that sink, and enzymatic degradation of polymers. Additionally, algae can serve as feedstocks for producing bioplastics, offering a dual role in both plastic remediation and sustainable material production.
Exploring the Potential of Algae in the Mitigation of Plastic Pollution in Aquatic Environments

Exploring the potential of microalgae in removal of microplastics from the environment and scope of this entity as feedstock for biofuel production
This review explores the potential of microalgae to capture and remove microplastics from aquatic environments, examining the mechanisms by which algal cells adsorb or aggregate plastic particles and discussing the feasibility of algae-based remediation at scale.
Algae for plastic biodegradation
This review examines how algae interact with microplastics in marine environments, both as organisms harmed by plastic pollution and as potential agents for plastic biodegradation. Microplastics reduce algal photosynthesis and growth, while algal extracellular polymeric substances can trap and sink microplastic particles. Algae-driven biodegradation represents a promising avenue for reducing the persistence of microplastic contamination in the ocean.

This review examines microalgae as a source of biopolymers for sustainable plastic alternatives, evaluating the potential of algae-derived materials to address the environmental and health harms caused by conventional plastic waste and microplastic pollution through biodegradable substitutes.
Nature’s fight against plastic pollution: Algae for plastic biodegradation and bioplastics production
This review explores two algae-based approaches to tackling plastic pollution: using algae to biodegrade existing plastic waste and using algae to produce biodegradable bioplastics. Researchers highlight promising early results showing certain algae species can break down conventional plastics, while algae-derived bioplastics offer a renewable and compostable alternative to petroleum-based materials.
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.
Microalgae for Plastic Biodegradation and Bioplastics Production
This review examines how microalgae biodegrade plastics through enzyme and toxin production while also serving as feedstocks for bioplastic manufacture, exploring both the mechanisms of algal stress from microplastic exposure and the potential of algae-derived biodegradable polymers.
The role of algae in regulating the fate of microplastics: A review for processes, mechanisms, and influencing factors
This review examines how algae influence the fate of microplastics in aquatic environments through processes including retention, flocculation, deposition, and biodegradation. Researchers found that algae can trap microplastics via adhesion and produce extracellular substances and enzymes that contribute to aggregate formation and partial breakdown of plastic particles, though these interactions are influenced by algal species, microplastic characteristics, and environmental conditions.

This review examines how microplastics and nanoplastics affect algae, which are the foundation of aquatic food chains. Microplastics can reduce algae growth, disrupt photosynthesis, and cause oxidative stress, with smaller nanoplastics being more harmful. Since algae are at the base of the food web, damage to them can ripple through ecosystems and ultimately affect the seafood that humans consume.

Effective removal of microplastics by filamentous algae and its magnetic biochar: Performance and mechanism
Researchers found that filamentous algae and a magnetic biochar made from the algae can effectively remove microplastics from water, with the biochar absorbing over 215 milligrams of microplastics per gram. The algae naturally trap microplastics through entanglement and adhesion, while the magnetic biochar can be easily recovered from water using magnets. This dual approach could help address both algae bloom problems and microplastic contamination in urban water systems.
