Microplastic remediation refers to environmental remediation techniques focused on the removal, treatment and containment of microplastics (small plastic particles) from environmental media such as soil, water, or sediment. [1] Microplastics can be removed using physical, chemical, or biological techniques. [2]
The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues. Microplastics, defined as plastic fragments smaller than 5 mm, and even smaller particles such as nanoplastics (NP), particles smaller than 1000 nm in diameter (0.001 mm or 1 μm ...
Last year, researchers in Qingdao, China developed a synthetic sponge made of starch and gelatin designed to remove microplastics from water, though its efficacy varied depending on water conditions.
Graphene-coated nanomembranes are said to be more applicable in water treatment due to its unique properties. Graphene membranes are obtained from vacuum filtration or coating of graphene oxide solution as Graphene oxide sheets. The graphene coated nanofiltration membrane showed a higher water flux range.

The captured microplastics in the treatment plants become part of the sludge produced by the plants. The problem is that this sludge is often used as farm fertilizer meaning the plastics enter waterways through runoff. [12] Fionn Ferreira, winner of the 2019 Google Science Fair, is developing a device for the removal of microplastic particles ...
A 2017 study found that 83% of tap water samples taken around the world contained plastic pollutants. [96] [97] This was the first study to focus on global drinking water pollution with plastics, [98] and showed that with a contamination rate of 94%, tap water in the United States was the most polluted, followed by Lebanon and India.
Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). [1]
