Microplastic remediation
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]
Remediaton of microplastics in water
[edit]Microplastics can be removed from water by filtration or absorption. Absorption devices include sponges made of cotton and squid bones.[3]
Biochar filtration has been used in wastewater treatment plants.[4]
Efforts to physically remove microplastics from the Great Pacific Garbage Patch have used nets and collection bags.[5]
Remediaton of microplastics in soil
[edit]Microplastics are commonly found in soil.[6][7] Techniques are under development to achieve reductions in soil microplastics via photodegradation, chemical extraction, or bioremediation.[8][9][10]
