In Indonesia, Borealis is to invest in the further expansion of the project launched together with Systemiq in 2017 that aims to reduce environmental pollution by plastic waste. With a comprehensive financing commitment to extend the project, Borealis wants to drive the circular economy for plastics in the region by setting up circular waste management systems.

Students at the Swiss Federal Institute of Technology (ETH) have tested technologies with which plastic waste is automatically removed from rivers. The young researchers, who want to tackle the global problem of marine pollution, are starting their project with rivers, so that the litter cannot get into the seas in the first place. With the help of a robot, the plastic bottles, toys or shoes fished out of rivers are to be automatically sorted and separated from biological materials.

The book provides a comprehensive overview of the effects of pollution by plastics on fresh water and seawater, and the resultant challenges when evaluating and managing plastic waste in the aquatic environment. In one of the chapters, BKV Project Manager Stephanie Cieplik explains the BKV model entitled "From Land to Sea: Model for the Documentation of Land-Sourced Plastic Litter".

This study, which was published in German in April, is a further development of the BKV model "From Land to Sea". The report reflects the discussion among experts which is now moving away from focusing solely on discharges of plastics into the seas, and calls for a more comprehensive look at the discharges and final whereabouts of plastics in the environment. The report now provides a holistic picture of the discharges and final whereabouts of plastic waste in the aquatic and terrestrial environments. An English version will follow shortly.

A team from the Geomar Helmholtz Center for ocean research in Kiel carried out a laboratory experiment over a period of 42 weeks in which they subjected juvenile blue mussels to various concentrations of microplastics. The results – recently published in "Science of the Total Environment" – are surprising: According to the authors, the study shows that the mussels are barely affected by microplastics in the water even over a long period of time.

Microparticles in the southern part of the North Sea stem predominantly from paints and surface coatings of ships' hulls. This was the result of a study from the Institute for Marine Chemistry and Biology of the University of Oldenburg. It claims to be the first study offering an overview of microplastic distribution in the North Sea. The research team led by Dr. Barbara Scholz-Böttcher found above all plastic particles stemming from binders of ships coatings. As a source, they are said to be of similar importance as tire abrasion on land. The results show that significantly more microplastic is produced on the open seas than previously supposed.

An international team headed by Gerald Schernewski from the Leibniz Institute for Baltic Sea Research in Warnemünde (IOW) has calculated on the basis of existing data and secondary literature how many particles of the most commonly used plastics with a size of between 0.02 and 0.05 mm from urban sources get into the Baltic Sea and how they behave there. In the opinion of the team, the results offer promising approaches for efficient monitoring and also for reduction measures.

In connection with the concluding conference of the funding priority "Plastics in the Environment", at which several joint projects also dealt with modeling approaches and measuring methods for the analysis of plastic discharges into the soil and wastewater (see our report), we asked an expert on the subject for his appraisal of the results and about the present situation with the standardization of the measuring methods: Dr. Claus Gerhard Bannick is head of the specialist department for wastewater technology research at the German Environment Agency (UBA).

Over a period of three years, specialists from different disciplines in industry, science and politics have been carrying out research in 20 joint projects within the research program "Plastics in the Environment – Sources, sinks, solutions", funded by the Federal Ministry for Education and Research (BMBF). On 20 and 21 April, the concluding conference took place online at which, reports the BMBF, many possible approaches in the areas of production, recycling and waste management were discussed. Possible solutions for the trade and for the utilization phase of plastics products and, not least, also for wastewater treatment, were also debated.

Under the leadership of the Augsburg geographer Prof. Peter Fiener, a research network was launched in March that aimed to examine the pollution of agricultural soil with macro- and microplastics called the "EU Innovative Training Network". With this program, the EU wants to support a new generation of innovative young scientists.
