Removal of Microplastic

Removal of microplastic

Inert organic-chemical stressors (IOCS) are compounds, which, due to longer degradation rates, remain in the ecosystem for a very long time and cause harm. Representatives of this group of stressors are the smallest plastic particles (< 5 mm), which are known by the term microplastic. Microplastic particles can enter the environment via municipal and industrial wastewater.

The concept for the removal of IOCS consists of two synthesis steps. The synthesis of the localization unit, the bioinspired part of the total molecule, forms the basis. This unit is marked by a characteristic preorganization and the ability to interact with the material to be embedded by means of the functional groups introduced. Finally in the second step, the unit becomes an inclusion compound through the addition of a fixation unit.

In order to remove microplastic particles sustainably, the inclusion agglomeration principle developed by Wasser 3.0 is applied on the basis of Cloud-Point Technology. Particle growth is induced by the sol-gel process. The significantly enlarged agglomerate (see figure) can thus be economically and efficiently separated from aquatic medium.
