In recent years microplastics in the environment has come in the focus of scientific discourse and the public eye. After several scientific works on marine litter and microplastics, the limbic systems are now the focus of several research projects. In order to get an idea into the extent of the microplastics flow into terrestrial systems, a method has to be developed to measure the microplastics in matrices that complex. Therefore the department of Material Flow Management and Resource Economy is working on an instrumental-analytical method for characterisation and quantification of microplastics in composts. Composts made from biodegradable household wastes can contain a substantial plastic contamination in the form of for example trash bags or food packaging materials. Through the preconditioning and composting process this material can be reduced to a size smaller than 5 millimetres. Financed through the Fritz and Margot Faudi-Foundation the project “co(MP)ost” aims to create a method for pre-analytical digestion and instrumental analysis of the plastic fraction in composts, via which compost flows can be measured reliably and representatively. This way the microplastic generation potential of different plant types can be compared. This shall enable a look into the microplastic influx into agricultural and horticultural soils which are fertilized with compost.
