Beschreibung

It is not easy to determine how much microplastic is contained in wastewater and sewage sludge. In addition to plastic, countless other particles and substances are present. To reliably determine the concentration of microplastic particles, complex procedures for sampling as well as for removal of foreign substances and analysis of the microplastic particles are required.

The PLASTRAT research team has set itself the task of developing methods for these procedures and thus advancing the detection of inputs to surface waters. In this context, they provide important insights into the relevance of wastewater treatment plants as a retention option for plastic particles.

The project focuses on the quantification and technical reduction potential of plastic emissions in the field of urban water management, including sewage sludge treatment. The results on method development have been summarized in the 11th fact sheet of the research focus. The fact sheet is available for PDF download here.

Plastics have become an integral part of our everyday lives, and cause many environmental impacts. The pollution microplastics is increasingly in focus. First, these tiny particles were discovered in the oceans, then were found in lakes and rivers and eventually the soil. "Plastic particles are everywhere," says Luisa Barkmann , a doctoral student in the area of waste water technology of the Technical University of Darmstadt (TU Darmstadt), in Germany. In his dissertation, she studied the presence of micro-plastics in municipal sewage treatment stations. Now, on his doctorate, she is dedicated to wastewater industry. She looks closely, especially the production companies and plastics processing: in which value chain stages and for which the plastic particles channels enter the environment? And what is the industry's share in the global burden?

As part of the joint project EmiStop, research teams based in Darmstadt are analyzing industrial wastewater to calculate their participation in contamination by micro - plastics. Not an easy task, because even sampling is a challenge, says Luisa Barkmann. For each company, she had to think of an individual strategy, as companies are different not only in their production processes, but also in its channels and water management systems. Many do not know how much wastewater is generated in a given area. And not only in manufacturing but also in particularly microplastic further processing and transfer to the environment.

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

Beschreibung

Around 50 scientists from 12 collaborative projects of the research focus on plastics in the environment met for a first exchange on sampling, sample preparation and analysis of microplastics at the Water Technology Center (TZW) in Karlsruhe. The workshop, organized by TZW and the Ecologic Institute, aimed to coordinate and learn from each other the many difficulties in identifying and quantifying microplastics from water or soil samples.

The workshop marked the beginning of the cross-cutting theme of sampling, sample preparation and analytics, which is one of the current five cross-cutting themes within the research field of “Plastics in the Environment”. In the cross-cutting issue, many scientists will network with each other over the next three years and significantly advance the development of methods for identifying and quantifying microplastics in the environment.

In the workshop, led by Prof. Dr. Martin Jekel, both the methods already used in the MiWa project and the previous approaches of the twelve joint projects were presented and discussed together. The particular difficulties in identifying and quantifying microplastics became apparent in the two days. Harmonization and comparability of the methods is sought by all participants. The workshop was a successful prelude to productive cooperation over the coming months and years.

Identification of Industrial Plastic Emissions by Means of Innovative Detection Methods and Technology Development to Prevent the Input into the Environment via the Wastewater Pathway

This project systematically detected emissions of plastics into wastewater from relevant industries. Emissions levels were analysed along all points of the value chain (production, transport, processing, and cleaning of synthetic materials).

The goal was to select wastewater treatment technologies that optimise the reduction of emissions of plastics for the respective value chain. The project evaluated existing technologies for separating particles, investigated deposition rates, and developed approaches for technical optimisation. Optimisation also includes technological developments such as flocculants. Researchers conducted tests in both laboratory and pilot project settings – selected large scale technical wastewater treatment plants were investigated at industrial facilities.

Due to the existing analytical uncertainties, the following detection methods were used to evaluate the existing and developed technologies:

Dynamic differential calometry for qualification and quantification (concentrations)
Raman spectroscopy for qualification and quantification (particle numbers)
Correlations of the plastic concentrations to routine water chemical analyses (for a retrospective estimation of the plastic loads)
Tracer test with magnetic plastic particles (simple and reliable quantification in large dilutions) for balancing in laboratory and pilot tests

Apart from the technical aspects, the focus of this project was also on socio-economic aspects. Thus, measures to prevent economic losses and retain value were reviewed together with the associated industrial enterprises and evaluated with partners from the scientific community and other interest groups.

Main areas of work

Standardisation of sampling and sample preparation for industrial wastewater (in alignment with Plastik-Net and other joint research projects)
Quantitative and qualitative measurement of plastic concentrations in industrial wastewater using Raman spectroscopy and dynamic differential calorimetry
Extended data collection at the sampled industrial waste water treatment plants for the derivation of the plastic loads and testing of a correlation between the measurement results and routine water chemical analyses
Development of magnetic plastic particles in the micrometre range with the physical properties of relevant types of plastic
Development of a tracer test with magnetic plastic particles
Assessment of technologies for particle separation with regard to the retention of (micro-) plastic particles
Optimisation of particle separation technologies
Development of flocculants for the targeted improvement of the retention of individual types of plastics and their mixtures
Delphi surveys of industry and sector associations as well as of politics and science to identify perceived risks and obstacles as well as opportunities and the willingness to participate
Multi-criteria analysis for the development of weighted, ecological and socio-economic criteria for the sustainability assessment of the project results

Short description
In order to balance individual process technologies for plastic particle retention in real water matrices, a method for the quantification of magnetic plastic particles by means of magnetic susceptibility scales was established. For this purpose, particles in the size range from 1 μm to 300 μm were synthesised with the greatest possible magnetic susceptibility, which imitate the morphologies and chemical properties of environmental plastic particles.

Furthermore, a continuous method for the production of these particles was established in order to ensure the best possible reproducibility and scalability for subsequent applications.

Ship-Based Treatment of Plastics for the Implementation of Value Chains in Less Developed Countries as well as for the Prevention of Plastic Inputs into the Environment and Especially in Marine Ecosystems

The aim of the project was to develop concepts and preliminary planning for the implementation of an infrastructure for the collection, ship-based treatment, and marketing of plastic waste in order to reduce the input of plastic waste into the environment and marine ecosystems. The project's target regions were primarily less developed countries in the Global South. Using West Africa as an example, strategies for reducing the input of plastics (in this case macroplastics) into the environment were researched, because the input of macroplastics into the environment is particularly high when functioning waste collection and disposal systems are lacking. Stakeholder dialogues were conducted to assess whether a commodity chain based on plastic recyclates is possible on the West African coast. A prototype model ship was developed and used to determine costs.

Main areas of work

Data collection, analysis and evaluation (local conditions in less developed countries)
Preliminary planning of waste treatment plants
Design of a concept for suitable ship and plant technology
Development of strategies for the implementation of value chains in less developed countries
Analysis and evaluation of results (economic, ecological)

The methods currently available for the analysis of microplastics in environmental matrices were primarily designed for particles in the size range of 1 μm to 5 mm. Smaller particles below 1 μm were hardly detected. However in contrast to larger particles, these are able to enter cells and have a higher potential for adsorption of pollutants due to their relatively larger surface. SubμTrack focuses on plastic particles between 50 nm and 100 μm, because of their higher ecotoxicological relevance. For this purpose, the previously available detection range was extended and new methods for sampling, sample preparation, and analysis were developed. Another focus of the project were the possible effects of submicroplastic particles on the aquatic environment and on human health. The results of these studies were complemented by an assessment of the social, political and legal dimensions of plastic emission into the environment. By analysing the perception of the problem and possible strategies for action, foundations were laid for active processes of social change. The results were also examined regarding to their implementation in legislation, standardisation, and their relevance for voluntary actions.

Project partner
TUM-IWC, TUM-LTI, TUM-LAS, TUM-MCTS, IGOE, LfU, UBA, IUTA, Postnova Analytics GmbH, BS-Partikel GmbH

Short description
In addition to the coordination of results and products within the consortium, WP 0 also included the coordination of activities with partners outside the project. The goal was the sustainable implementation of the analytical techniques, the results and the instructions for action of harmonised strategies in close cooperation with national and international key institutions. The public relations work was mainly coordinated by TUM-SWW and effectively implemented by partners of different orientations.

WP 1 Selection and production of reference particles

Contact persons
Dr. Carmen Nickel, Dr. Jochen Türk, Institute of Energy and Environmental Technology e. V. (IUTA), Bliersheimer Str. 58- 60, 47229 Duisburg, e-mail: nickel@iuta.de; tuerk@iuta.de

Project partner
LfU, BS-Partikel GmbH

Short description
Together with the partners of BS-Partikel and the leaders of the experimental WPs 2 – 5 the required reference particles were identified. In particular, the size, material, marking and the availability of the particles played an important role. The reference particles were selected during the initial phase of the project in order to have enough time to fabricate or purchase the particles at the beginning of the experiments. The project partners BS-Partikel and IUTA then provided the corresponding particles.

WP 2 Comprehensive analysis of microplastic particles

Prof. Dr. Martin Elsner, Dr. Natalia P. Ivleva, Technical University of Munich, Chair of Analytical Chemistry and Water Chemistry, Institute of Hydrochemistry, Marchionistrasse 17, 81377 Munich, e-mail: natalia.ivleva@ch.tum.de

Project partner
Postnova Analytics GmbH, BS-Partikel GmbH, TUMSWW, TUM-LTI, LfU, IUTA

Short description
Innovative and proven analytical detection methods (including sampling, preparation, identification and quantification) for microplastics (1 μm – 5 mm) were determined and tested with reference materials in the submicron range. The most successful techniques of the MiWa project running since 2016 serve as a starting point for this; standard methods from this project were integrated and compared. Direct contact to actors of the MiWa project was guaranteed by partners of the consortium (TUM-IWC and UBA).

WP 3 Studies on aging, adsorption and desorption of organic trace substances on reference particles

Project partner
LfU

Short description
The particles used in the method validation are subjected to systematic aging processes and biofilm growth. Furthermore, these particles and especially their (resulting) different surfaces were examined regarding their adsorption or desorption characteristics of organic molecules. For this analysis, adsorption and desorption kinetics, among other things, were investigated. This was done by applying TD-(Pyrolysis)-GC-MS and LC-MS/MS. Experiments with the aged particles were carried out in so-called batch approaches, but also in laboratory wastewater treatment plants operated at the LfU. All samples were also stored in the biological systems of WP 5 if required.

WP 4 Investigations on entry points and process-related evaluation

Project partner
TUM-SWW, IUTA

Short description
Using the methods developed and validated in WP 2, real scenarios were first simulated with reference particles in laboratory wastewater treatment plants at the partner LfU to analyse the fate of the particles within the system. Parallel to this, investigations were carried out at various measuring points in real wastewater treatment plants. Water samples were certified by IUTA for micropollutants. The aim was to extend the existing sampling technologies to micropollutants. Finally, together with the other partners of the project and based on the expected results, a process-related evaluation was carried out.

WP 5 Impact on aquatic environment and human health

Project partner
TAM-LAS, IGOE

Short description
Potential negative effects of submicroparticles on different biological organisational levels were investigated and compared to obtain a comprehensive ecotoxicological evaluation. This includes the use of model systems in vivo to determine effects on microbial diversity, communities and trophic structures and functions as well as to identify stress reactions on a higher organismic level. In vitro models extended this approach for the determination of effects on the cellular and molecular level. Based on this a mechanistic understanding of particle-induced stress reactions was created and potential effects on human health were derived.

WP 6 Social, political and legal dimensions

Contact person
Prof. Dr. Ruth Müller, Technical University of Munich, Assistant Professorship of Science and Technology Policy, Augustenstraße 46, 80333 Munich, e-mail: ruth.mueller@tum.de

Project partner
UBA

Short description
At TUM-MCTS current problem perceptions and coping strategies in society and politics with regard to plastic particles in the environment were analysed by means of qualitative social scientific methods. The focus lay on the perception of the specific ecotoxicological relevance of submicroparticles. UBA carried out a screening of the relevant legal acts at national, European and intercontinental levels. The consideration goes beyond the pure media reference (water, soil and air) and the associated possible transport paths. In particular, the legally undefined range between nano- (limit: 100 nm) and microplastics (frequently stated limit: 1 μm) is of primary interest.
