Microplastic remediation

Last updated

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]

Contents

Microplastics can be removed using physical, chemical, or biological techniques. [2]

Remediation of microplastics in air

Microplastic is a type of airborne particulates and is found to prevail in air. [3] [4] [5]

Remediation of microplastics in water

Microplastics can be removed from water by filtration or absorption. Absorption devices include sponges made of cotton and squid bones. [6]

Biochar filtration has been used in wastewater treatment plants. [7]

Efforts to physically remove microplastics from the Great Pacific Garbage Patch have used nets and collection bags. [8]

Remediaton of microplastics in soil

Microplastics are commonly found in soil. [9] [10] Techniques are under development to achieve reductions in soil microplastics via photodegradation, chemical extraction, or bioremediation. [11] [12] [13]
