Kurzbeschreibung (Abstract)
According to A European Strategy for Plastics in a Circular Economy, in 2015 the EU generated 26 million tons (Mt) of plastic post-consumer waste. 1.75 Mt of 7.8 Mt collected for recycling was exported to China. China's ban on waste import starting from 2018 forces EU to take sustainable alternatives. Reduction/prevention of the use of synthetic plastic products will be the must. It is likely that the use and the variety of biodegradable and recycled plastic materials is to be increased. This shift in plastic waste management also requires the study to investigate sorption behaviours of pollutants onto new plastic materials. Here we present a quick and reproducible method to compare sorption capacity of persistent organic pollutants (POPs) on a variety of plastic resin pellets from different origin. Resin pellets tested here were made from widely used synthetic polymers, post-industry and post-consumer recycled products as well as biodegradable polymers. The sorption test was conducted in water containing selected POPs with cosolvent (water: solvent = 70:30, volumetric). Cosolvents selected were miscible in water, owns a vapour pressure smaller than 60 hP and can dissolve selected POPs in mg/L range. Sorption capacities of the POPs on pellets from different origins were compared by exposing a given mass of pellets in the mix-solution containing the POPs with a fixed starting concentration, 1000 µg/L. In addition, partition coefficients of selected POPs between the solution and pellets from different origin were determined by varying the initial POP concentrations in the mix-solution. The derived partition coefficients were evaluated whether they can be used as predictors to derive partition coefficients of the POPs between water and the polymers. TU Darmstadt and CARAT are participants of an EU project “PLASTOX”, a consortium of a JPI Oceans' Joint Action. TU Darmstadt is funded by BMBF.
