The event brought together around 70 scientists, representatives from the EU institutions, as well as stakeholders from civil society and businesses to discuss the non-intentional release of microplastics into the environment.

RD Dr. Martin Dubiel (Representation of the Free State of Bavaria to the European Union) opened the event and gave the introductory words of welcome. The welcome address was given by Dr. Frieder Kettemann from the German Federal Ministry of Education and Research. R. Andreas Kraemer, who moderated the event, gave a short overview on the current political framework regarding plastics and recent developments at different political levels.

In the introductory talk, Werner Bosmans (DG Environment) outlined the political mandate for (micro)plastics regulation at EU level, the relevant sources of the non-intentional release of microplastics into the environment and the existing regulatory framework for microplastics at the EU level. During the Q&A subsequently to the presentation, Mr. Bosmans emphasized that there is a lot more research needed with regards to sampling methodologies to gather information on the presence of microplastics in soils across the EU as well as how this could be monitored at member state level.

The first session addressed the issue of tire abrasion with presentations from Mag. Dr. Romana Hornek-Gausterer (Environment Agency Austria) and Prof. Dr. Ing. Matthias Barjenbruch (Technical University Berlin). Ms. Hornek-Gausterer focused on additives used in tires, more specifically on para-substituted phenylenediamines (PPDs). She concluded that environmental monitoring is needed to understand which substances/products are of concern and to learn about the occurrence, transport/fate and behavior in the environment for such particles and substances. Prof. Barjenbruch presented results from the RAU project on tire abrasion and suggested measures to reduce the entry of tire particles into the aquatic environment.

In the second session on textiles fibres, Dr. Korinna Altmann (Federal Institute for Materials Research and Testing, RUSEKU project) explained the results of washing machine tests with regard to the release of textile fibres from clothes such as shirts during typical washing processes with a household washing machine. The second presentation, held by Nicklas Gustavsson (Ramboll), dealt with geotextiles which are, for instance, used in road construction or for erosion control. Mr. Gustavsson highlighted the major research gaps that exist regarding the use of geotextiles and the potential discharge of microplastics during the use phase or while removing geotextiles from the environment.

The third session started with a presentation of Felix Weber (RheinMain University of Applied Sciences) and Luisa Barkmann-Metaj (Technical University of Darmstadt) who presented results from the EmiStop project on industrial microplastic and pellet loss. The two researchers presented their findings on industrial microplastic emissions at industrial sites and possible reduction measures. Afterwards, the presentation by Dr. Ulrike Braun (German Environment Agency [UBA]) and Dr. Nizar Benismail (Nestlé Quality Assurance Center Vittel) introduced the work of the joint ISO working group on microplastics of which both are active members. A challenge in the standardization work is the harmonization of standards that are currently developed in several different working groups.

In the last session, Dr. Saskia Ziemann (Project Management Agency Karlsruhe) presented the key messages from the German research focus “Plastics in the Environment”, while Prof. Dr. Christian Laforsch (University of Bayreuth) indicated future research needs that will – at least partially – be tackled by the Collaborative Research Centre 1357 Microplastics.

The event “Tackling microplastics in the environment” did take place on 9th March 2023 in the Representation of the Free State of Bavaria to the European Union in Brussels and was organized jointly by Ecologic Institute for the research focus “Plastics in the Environment – Sources • Sinks • Solutions” of Germany’s Federal Ministry of Education and Research, the Collaborative Research Centre 1357 Microplastics at the University of Bayreuth and the Interest Group Plastics of the EPA network.

Environmental Policy Instruments to Reduce Plastic Pollution of Inland Waters through Drainage Systems

The project aimed to make a significant, transdisciplinary contribution to applied research on the prevention of plastic discharges into water bodies via drainage systems from a behavioural and environmental economics perspective. In four model municipalities, the project recorded the quantity and type of plastics discharged into the drainage systems via wastewater and precipitation water collection in municipal wastewater treatment plants and precipitation drains within one year. The data obtained was then extrapolated for Germany by means of material flow analysis. With regard to regulatory deficits, instruments to reduce plastic inputs were developed in an interplay of legal and behavioural economics analyses. Selected instruments were tested in field experiments in companies and households. On this basis, the project partners developed policy briefs that inform policymakers, practitioners and associations about ways to measure and reduce plastic inputs into the environment.

Main areas of work

Analysis of legal framework conditions
Empirical investigations of plastic discharges into the drainage systems of four model municipalities
Model-based visualisation of the material flows from the considered input sources, namely households, transport routes and companies of the plastics industry in the model municipalities
Development of behaviour-based measures to motivate behavioural changes
Computer simulations of the effects of behaviour-based measures
Evaluation of the effect of measures by means of field experiments

Prof. Dr. Frank Beckenbach, FIW

Short description

Starting from a behavioural economics analysis of relevant behavioural effects regarding the use of plastics in households and companies and possible approaches to motivate changes in their use as well as an investigation and deficit analysis of the existing legal framework at national and European level, behavioural measures and instruments were identified. Their effects with regard to ecological, social, technical, legal and economic feasibility were assessed. The result was a preliminary set of instruments, which were used as a basis for all further investigations and were adapted if necessary.

WP 3: Empirical analyses of success factors and barriers

City of Aachen, City of Stolberg, Simmerath Municipality, Roetgen Municipality, Prof. Dr. Frank Beckenbach, FIW, Darmstadt University of Applied Sciences

Short description

The empirical determination of the success factors and barriers of instruments for the reduction of plastic inputs via the drainage systems was based on the concept of multi-criteria behaviour-oriented instrumentation. The focus of the investigations were the actor groups households and companies. The investigations were preceded by expert discussions. A methodological triangulation was used: semi-structured, guideline-supported in-depth interviews were carried out as well as, in the case of households, a telephone survey and, in the case of households and companies, a field experiment.

Project partners

University of Kassel, Darmstadt University of Applied Sciences

Short description

Material flow models for plastic discharges of macro- and microplastics from the identified sources into the drainage systems were developed for the four model communities. Based on the model results, the sources and product types were analysed and evaluated with regard to their relevance for the plastic inputs. The data from the municipalities was then extrapolated to the federal level in a general model.

Short description

In this work package the design and development of multi-agent systems was carried out, which cover the actor groups households and companies. Based on the actor concept of WP 2, the multi-agent systems map actor-related decision-making processes and determinants of plastics use were linked to the material flow models from WP 4 in a subsequent step. Different legal and behavioural instruments and their material-ecological and economic implications were analysed and evaluated on the basis of different scenarios.

WP 6: Finalisation of the concept of multi-criteria, behaviour-oriented set of instruments

Contact person

Project partners

Prof. Dr. Frank Beckenbach, University of Kassel, FIW

Short description

In parallel to work packages 3 to 5, the concept of multi-criteria behaviour-oriented set of instruments were further specified by including the results of empirical studies and the multi-agent system. For the identified instruments and measures, it was estimated how they could work in practice, what control and enforcement effort they might create for authorities, whether they could be combined in certain areas, and what medium- and long-term effects the regulations could have. The adjustments to the concept were tracked and evaluated through computer simulations.

Beschreibung

On September 14, 2018, scientists from the research focus "Plastics in the Environment" met in Berlin for a first exchange meeting within the framework of the cross-cutting issue area 3 "Terms and Definitions".

In four introductory talks, definitions of microplastics with different focuses were presented (including microplastics in standardization, relevance of substance legislation, microplastics definitions from the point of view of analytics).

In the subsequent discussion, it was agreed that the aim of cross-cutting issue area 3 should be to create a common language for the research focus. To this end, an attempt should be made to agree on a common definition or a common understanding of important terms (i.e. not necessarily to define them themselves).

A glossary will be developed in the further course of the research focus. First terms to be included in the glossary were collected at the meeting.

Representative Investigation Strategies for an Integrative System Approach to Specific Emissions of Plastics into the Environment

This project developed representative investigation methods and strategies for an integrative system understanding of relevant plastic entry paths into the environmental compartment water. The developed sampling methods were evaluated in terms of their concentration concept, their local use, their sampling throughput, and their selectivity for particles of different properties, sizes, and shapes. For this purpose, defined microplastic particles were produced with these varying characteristics and tested for representative recovery of sampling procedures in the laboratory and in semi-industrial simulation facilities. The methods developed in this way were translated into specific investigation strategies, adapted - with the aid of supporting simulation methods - and then applied to real environmental areas for different transport paths in the urban wastewater system. In addition to the academic understanding of microplastic entry points, causes and pathways, market-ready methods for efficient microplastic sampling were developed in cooperation with the companies involved. These methods form a basis for evaluation by legislators and for standardisation.

Main areas of work

Development of efficient, integrative and representative research methods and strategies (accuracy, repeatability, transferability) for the determination of relevant microplastic contents over the different areas of the water cycle
Establishment of goal-oriented, analytical methods for the detection of microplastic particles according to practical aspects
Simulations of the dynamics of particles in water bodies in semi-industrial laboratory tests
Further development of sampling to quantify the microplastic volume and transport in the real, urban waste water system for the waste water fractions: precipitation water, domestic waste water, and industrial waste water
Generation of a simulation code for the dynamics of microplastic particles in waters

Short description
First, defined, heterogeneous microplastic mixtures were developed for the environmental testing in water and soil. After the initial use of existing materials (e.g. particles from cryogenic grinding, commercial products), plants for the realistic and defined production of microplastic particles were set up during the project period: UV degradation systems for thin-walled, defined materials, dry or aqueous mechanical abrasion systems for fibres from textile applications, and abrasion simulation systems for the generation of spherical particles. The other project partners contributed to the characterisation of these model materials by applying their analytical methods.

WP 2 Development of sampling methods

Short description
In WP 2, efficient, reliable and reproducible sampling methods and strategies were developed for the microplastic model particles of different varieties, densities, sizes and shapes in the stream simulation facility at UBA. Their usability and reproducibility was also investigated for routine operation and the methods will be evaluated based on the recovery rates of experiments. The individual project partners optimised their analytical procedures: from the use of conventional flow-through centrifuges to the cascade filtration system, suspended matter traps, hydrodynamic modelling, and lysimeter tests to the control of possible input into groundwater.

Short description
The methodological developments from WP 2 were supported by accompanying simulations in WP 3. These simulations resulted in a description of the vertical distributions of spheroids at different particle sizes and shapes in a turbulent surface water or stream simulation facility. The models and results were integrated into a software that simulates geometrically complex, application-oriented cases. A sampling strategy was derived from the simulation results. Relevant material parameters of the particles such as size distribution, real density or surface properties from WP 1 as well as from partners from WP 5 were included.

WP 4 Sampling of real environmental compartment

Prof. Dr.-Ing. Heidrun Steinmetz, Technical University of Kaiserslautern, Institute of Water - Infrastructure - Resources, Paul-Ehrlich-Straße 14, 67663 Kaiserslautern, e-mail: heidrun.steinmetz@bauing.uni-kl.de

Project partner
UBA, TUM, KMT

Short description
The main focus of WP 4 were the quantification of the microplastic volume and transport in the real, urban wastewater system for the wastewater and precipitation water, domestic wastewater (partial flows grey and black water), industrial wastewater, and mixed wastewater. The findings from the sampling in WP 2 were implemented and improved. Further work focused on sample preparation and preservation to evaluate the comparability of different sampling strategies. The investigations focused on the quantities and the importance of microplastic volumes in the individual entry points of the urban wastewater system into the water bodies.

WP 5 Analytics

Contact person
Dr. Ulrike Braun, Federal Institute for Materials Research and Testing (BAM), Division 5.3 Mechanics of Polymers, Unter den Eichen 87, 12205 Berlin, e-mail: ulrike.braun@bam.de

Project partner
CSP, TUM, FHI

Short description
The analytics used in the individual work packages were based on the requirements for sample preparation and analytical procedures as well as on the necessary information to be generated, not on the general feasibility. WP 5 served the intensive exchange of results generated with complementary analytical methods. In addition, the respective methods, supported by the results of the other project partners, were further refined and adapted.

Case studies

As a real environmental simulation, individual components of the wastewater system of the city of Kaiserslautern were investigated. In concrete terms, precipitation water was sampled here on settlement and traffic areas as well as domestic and industrial wastewater.

In addition, air sampling was also carried out at the limits of comparable sampling sites at locations in Berlin and in the Halle/Leipzig area. The planned lysimeter tests were carried out in Berlin and thus allow an assessment of groundwater recharge in Berlin and Brandenburg.
