Advancing Research and Regulations to Mitigate Impacts of Microplastics

Research on microplastics has increased exponentially in recent years, however translation of studies and data into knowledge that's useful for management requires clear communication between the scientific and management communities. Recent government mandates to manage impacts of microplastics prompted rapid development of tools and methods for identifying and assessing risks, monitoring their occurrence, and modelling their transport. Despite these remarkable scientific advances, additional research is needed to overcome barriers preventing the full emergence of microplastics as a regulated contaminant suite. This talk provides critical insights from both scientific and regulatory perspectives regarding recent advances in the field and recommends a path forward to overcome these barriers.

PET degradation by enzymes – impact and engineering of protein-surface interactions

Plastic-degrading enzymes have garnered increasing attention over the past decade as potential tools for addressing plastic waste recycling challenges. However, their efficiency in industrial applications is generally limited. A key issue is that these enzymes have not evolved to interact specifically with plastic. While many proteins tend to adhere nonspecifically to plastics, enzymes must establish precise and productive binding interactions. This specificity is essential to allow the enzyme's active site to engage with the substrate while permitting its subsequent detachment from the surface. To overcome this challenge, we explore the utilization of natural protein modules, which nature employs to facilitate interactions between enzymes and recalcitrant polysaccharides such as cellulose, starch, and chitin. Although a handful of these modules have shown promise in binding to plastic substrates, this binding diversity has not yet undergone systematic investigation. We employ a diverse array of methods to elucidate the molecular mechanisms governing these interactions: pull-down assays (high-throughput setup), enzymatic assays, NMR spectroscopy, and newly developed microscopy methods.

Aging of Intentionally Produced Microplastic Particles for Innovative Applications

Microplastics are ubiquitous in the environment, but their fragmentation and degradation mechanisms are not fully understood, although essential to estimate their fate and impacts. Industry has a responsibility to develop polymers that fit into a sustainable circular economy, so we aim to fill knowledge gaps regarding degradation and fragmentation processes of microplastics in different environmental compartments with the aid of appropriate laboratory set-ups for experimental reproducibility and environmental relevance. To investigate partially biodegraded microplastics occurring in complex environmental matrices, non-destructive extraction protocols with extensive controls are needed to assure particle and polymer stability, homogeneous sampling and appropriate recovery. We did biodegradation tests in combination with the developed extraction protocol for polyurethane (PU) microplastics to reveal which chemical design is needed to improve biodegradability of PU microplastics in the environment. In addition to that we developed an adapted NanoRelease protocol to investigate dry UV aging of polyamide and PU microplastics, as well as the release of micro- and nanoplastic fragments and water-soluble organics. In both studies, microplastic degradation resulted in fragmentation, but degradation strongly depends on the polymer composition and the environmental stresses. Overall, we want to underline the importance of quality control by reference materials used for spiking, extraction efficiency, and systematic comparison against blank controls for microplastic aging, extraction, harmonized data report and analysis.

Tailor-made functional papers – a complex low-cost material in high-tech applications

Paper has been known for thousands of years for its unique profile of properties: bendable & foldable, high mechanical strength, and its pore structure enabling pump-free fluid transport. Its production and recycling can nowadays be seen as technologically well-optimized. It has an environmentally friendly image and fosters the growing desire of the public for sustainable materials solutions. Despite its classical applications as print, packaging and hygiene paper, it has been in focus for several years in very challenging areas, e.g. in lateral flow tests (LFT), light-weight construction materials (e.g. as a honeycomb core in door leaves or shelves), as well as most recently in paper-based packaging as well as paper-based soft robotics. In this talk I will introduce our recent efforts in understanding and tailoring paper properties by controlled functionalization of the fiber and paper-sheet interfaces. Examples progress from the use of functional wax-polymer coatings to modulate barrier properties to cross-linking of polymers with paper fibers to introduce wet-strength properties in a sustainable fashion and the spatial control of interfacial attachment of polymers inside paper to gain 4D paper-based actuators.

The microplastic microbiome

Microplastics in the ocean are readily colonized by a broad range of microorganisms. The talk will cover which microorganisms use microplastics as a habitat, how environmental factors drive this colonization, and why biodegradation of plastic in the marine system is overall an unlikely process. We will also discuss whether potentially pathogenic microorganisms are hitchhiking on microplastics. Finally, potential ecological consequences of the microplastic-microbiome-interactions will be presented.

The SFB 1357 teams of project C01, Teresa Menzel, Nora Meides and Anika Mauel as well as team C04 Gerasimos Gkoutselis and Stephan Rohrbach give insights into their microplastics research. If plastics or microplastic particles are in our environment, they are exposed to a wide variety of influences such as solar radiation, mechanical stress, biofilm formation and the microbial communities in water and soil. How do macroplastics actually turn into microplastics, and is the plastisphere developed by fungi as a new habitat? We are curious what the PhD students will report!

Closing the gap between laboratory and field tests to investigate the aquatic degradability of plastics

The lecture deals with the question of how the gap between laboratory tests and real environmental conditions can be closed for the investigation of the aquatic degradability of plastics. In this context, the associated technical approaches (e.g. "rocking shaker", microCT) as well as first results from them will be presented. The overall objective is to improve the understanding of the relationships between the degradation processes (mechanisms, kinetics, half-life), the environmental conditions (oxygen availability, temperature, salinity, light irradiation, time) and the material parameters (molecular structure, microstructure, specific surface area) for the specific development of aquatically degradable bioplastics.

05.12.2022 - Prof. Dr. Nelson Odume: How should we consider the role of hydraulic habitats and traits in the study of the distribution and effects of microplastics in riverine systems?Hide

Prof. Dr. Nelson Odume, Institute for Water Research at Rhodes University, South Africa

How should we consider the role of hydraulic habitats and traits in the study of the distribution and effects of microplastics in riverine systems?

The transport and distribution of microplastics in riverine systems at the reach-scale are mediated by hydraulic characteristics such as depth, flow velocity, surface roughness. These factors interact with MP characteristics such as density, size, polymer type to influence the sedimentation, advection, dispersion, diffusion, settling, re-mobilisation, adsorption, and aggregation of MPs. At the reach scale, pools, riffles, and runs are hydraulic habitats, reflecting a combination of substrate type, depth, and flow velocity. These hydraulic habitats may vary from shallow-fast flowing-, shallow-slow flowing-, to deep-fast flowing- and deep-slow flowing waters, so that MP in rivers tend to settle and potentially re-mobilise in the slow-flowing hydraulic habitats and are transported speedily in the fast-flowing hydraulic habitats. Thus, in relation to MP transport at the reach-scale, the slow flowing hydraulic habitats can be likened to “sink zones”, whereas the fast-flowing hydraulic habitats, the “flush zone”. Viewed this way, rivers are thus made up of patchy series of sink and flush zones for MPs.

Macroinvertebrates, through their trait are adapted to different hydraulic habitats, which may impose on them different levels of exposure to MPs in the sink and flush zones. Drawing on the habitat template concept, and principles of hydro-geomorphology, this talk shed light on the role of hydraulic habitats in the distribution and transport of MPs, and why it is important to consider this important dimension in the ecological study of MPs. This talk also provides insights into how traits may mediate organismal exposure to MPs at the reach scale.

Arable soils - a leaking sink of microplastic?

This talk will focus on the potential importance of surface runoff and soil erosion as long-lasting pathway of microplastic from arable soils to inland waters. It will be subdivided into a general introduction regarding the challenges in dealing with soil and microplastic erosion on larger scales and will present original research comprising microplastic erosion process studies as well as first modelling approaches quantifying the erosion transport pathway in a mesoscale catchment. The latter underpins that even if the microplastic input to arable soils could be regulated today, soils would remain a diffuse microplastic source for inland waters for centuries

Modeling the release of plastic and microplastic to the environment

There is still a lot of uncertainty about the quantity and main sources of plastic emissions to the environment. This presentation shows how a combined (dynamic) material flow and release modeling can be used to quantify the current and historic releases of macro- and microplastics to the environment. A polymer-specific approach is needed as large differences between the released amounts and the receiving compartments exists.

Insights CRC 1357 Microplastic: Tracing Microplastic transport on soil surfaces and the water-sediment boundary

The SFB 1357 members Jan-Pascal Boos and Hannes Laermanns provide insights into current microplastics research. Microplastics have been ubiquitously detected in the environment. Since Microplastic particle properties can be substantially different from natural sediments, little is known about the specific transport mechanisms responsible for the distribution from anthropogenic sources to natural sinks. We present two approaches to track pristine and biofouled fluorescent microplastic transport in two different systems: On the water-sediment boundary using an experimental flume setting and during runoff using laboratory setup and computer simulations.

Diverse microplastics and where to find them: Learning from natural sediment to tackle microplastic challenges

Although our knowledge of microplastics is rapidly increasing, we still have difficulties in describing these diverse particles and in understanding the basic transport processes of microplastics in the aquatic environment. However, research on natural sediments offers many approaches that can be applied or adapted to microplastics. This presentation will show what we can learn from natural sediments when it comes to particle and transport description and where we need to focus our efforts in the future.

Possibilities to group micro- and nanoplastic particles: Insights from the perspective of the BMBF project InnoMat.Life
PD Dr. Andrea Haase, Chemical and Product Safety, German Federal Institute for Risk Assessment (BfR)

Compared to grouping of conventional substances or nanomaterials, establishing grouping approaches for micro- and nanoscaled plastic particles (MNPs) is much more challenging. The description of the chemical composition is more complicated for polymers and these particles are inherently heterogenous in many key properties.

This talk will provide an overview on the experimental work conducted within the InnoMat.Life consortium (www.innomatlife.de) to challenge possible grouping criteria using a variety of selected MNPs including several types of polyethylene, polyamide, polyurethane, polymethyl methacrylate and a rubber material obtained from recycled truck tires. As potential grouping criteria we assessed, among others, surface reactivity and biological effects considering human and environmental model systems, transport of different environmental contaminants, sedimentation and flotation behavior as well as ageing and fragmentation rates.

Based on our current data first conclusions concerning suitable approaches and criteria for grouping of different MNPs are possible. Our work is important for developing approaches to assess risks for human health and the environment.

Protein Engineering for Plastic Management
Prof. Dr. Ulrich Schwaneberg, Biotechnologie, RWTH Aachen

Plastics production reached ~370 million tons worldwide and our environment is massively contaminated with plastic waste. Microplastic contaminations alone are estimated to be in total 1.8-5.0 Mio tons with a yearly increase of 42 000 t (source European Chemical Agency; ECHA). Microplastic-particles can still be found in daily-used products such as cosmetics, cleaning/laundry products, and fertilizers. Based on bioaccumulation studies of Microplastic-particles the ECHA recommends wide-ranging restrictions on Microplastic in products to ensure human and environmental health. This ‘ban on microplastic’ is expected to be adopted into EU legislation till 2022, however, so far no ‘holy grail’ analytics has been developed to enable material-specific quantification of Microplastic-particles in high-throughput. In the presentation I will outline the advancement that we have achieved in designing by material-specific binding through protein engineering methodologies and their application in microplastic quantification and degradation.

Assessment of health risks of high aspect ratio materials (HARM): New techniques for material control and testing
Dr. Dirk Broßell, Partikelförmige Gefahrstoffe, Bundesanstalt für Arbeitsschutz und Arbeitsmedizin, Dortmund

Dust of high aspect ratio materials (HARM) can be hazardous to human health when inhaled. The classical fibre pathogenicity paradigm (FPP) predicts a carcinogenic potential in humans for inhalable biodurable fibres. Innovative testing methods and the availability of materials with narrow diameter distributions like carbon nanotubes and synthetic polymer fibres will and have already contribute(d) to a better understanding of the underlying pathomechanical cell effects that motivate a revision and extension of the FPP. Apart from implementing appropiate safety measures for workers, risk prediction enables the identification of parameters for designing and manufacturing safer HARM.

The topics environment protection and sustainability are currently being intensively discussed  in society, the media, sciences and politics. “Fridays for Future” may act as a prominent example here. However, on closer inspection, it becomes clear that many citizens show great interest in these topics, but are often rather uninformed with regard to details.

For this reason, science communication is of great significance. In this lecture, first some theoretical basic knowledge on science communication based on the example of microplastics is presented, after which some concrete event formats and their evaluation results are discussed.

Polyethylene is the most important plastic with excellent materials properties due to its crystallinity, yet it is persistent in a natural environment. We pursue approaches to endow polyethylene-like materials with a non-persistent nature by introducing low densities of functional groups as break points in the chain. Key are polymerization catalysis methods that are compatible with such functional groups. These also provide access to unique polymer micro- and nanoparticles for studies of the fate of microplastics in the environment.
