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]
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.
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 ...
Conventional paper coffee cups, with internal plastic coating, release many nanoplastics into water. [ 81 ] [ 82 ] Common single-use plastic products, such as plastic cups, or even paper coffee cups that are lined with a thin plastic film inside, release trillions of microplastic- nanoparticles per liter into water during normal use.

In nanotechnology, nanomembranes are used with the purpose of softening the water and removal of contaminants such as physical, biological and chemical contaminants. There are a variety of techniques in nanotechnology which uses nanoparticles for providing safe drinking water with a high level of effectiveness.
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.
