Abstract: A system and method for creating and collecting magnetic microplastics effectively combines magnetic material with plastics during their manufacture, thereby producing microplastics that can be easily collected via removal devices equipped with magnetic components. Magnetic particles are mixed with plastic/rubber resins during manufacturing of tires, roofing materials, and other plastic items.
