Ridding aquacultures of microplastics
Microplastics are not only found in oceans and inland waters, but also in aquacultures. Consequently, they enter the food chain via fish. One of the reasons for this are so-called growth bodies, which are used in closed pond systems for water treatment. The problem: these filters are made of petroleum-based plastics. Researchers at Hof University of Applied Sciences have come up with an alternative for aquaponics, the joint cultivation of fish and vegetables.
