Virtual microplastics are created by the use of synthetic polymers in the manufacture and processing of products. This is regardless of whether the final product contains plastics or not. The useful properties of the more than 200 types of polymers and their various subcategories mean that they are used in most production processes. 370 million tons of plastics were produced and processed in 2019.
If the final product contains plastics, it is called primary microplastics. These are listed under the ingredients. Examples are cosmetics, cleaning agents and fertilizers. If there is decay or decomposition of plastics in the environment due to improper disposal, we speak of secondary microplastics.
Virtual microplastics are not visible to consumers.
As waste products of production processes, they are nevertheless present. In quantities whose dimensions are so far largely in the dark.
Virtual microplastics are mainly discharged with industrial wastewater (process water, wash water) into the sewer system or directly into adjacent rivers. For the discharge of virtual microplastics there are no legal limits worldwide so far, i.e. they enter the environment uncontrolled.
