TY - CONF A1 - Bäßler, Ralph T1 - Compatibility of polymers exposed to heating oil blends with 10 % and 20 % biodiesel (FAME) N2 - Biodiesel (FAME) from rapeseed is an environmentally friendly alternative to common fossil fuels. It is also suitable to serve as blending component to fuels like heating oil. If the fuel composition is changed, materials compatibility must be guaranteed. Adding polar biodiesel to nonpolar heating oil, changes the blend’s solvency and might cause swelling, extraction and solvation of polymers. The objective of this research was to investigate the compatibility of polymeric materials, which are commonly used for components in middle distillate facilities, along with blends of heating oil and 20 % biodiesel (B20). For this propose, ACM, HNBR, FKM, PE, PA 6, POM, PUR and PVC were exposed to heating oil and B20 for 42 and 84 days at 40 °C. In addition, the polymers HNBR, FKM, PA, POM and PVC were also exposed at 70 °C. Furthermore, the resistance of polymers in eight-year aged B10 at 40 °C was evaluated. Ageing of biodiesel increases acidity which might propagate polymer corrosion. The materials were evaluated as resistant, if the loss in tensile properties (tensile strength and elongation at break) and Shore hardness remained under 15 % compared to the initial unexposed material values. For investigations under compressed conditions, the compression set was determined for specimens of ACM, FKM and HNBR after exposure in heating oil B0 and B20 for 3,7,14, 28, 56 and 90 days at 40 °C according to ISO 815-1. It was found that the resistance in B20 at 40 °C was given for all tested polymers except PUR. In the 8 years aged B10, PUR and POM were not compatible and ACM just conditionally compatible. At 70 °C, FKM and PVC were resistant in B20, whereas HNBR and PA 6 were not compatible. Swelling occurred for the elastomers ACM, HNBR and PUR.

Biocides are antimicrobials used as disinfectants, antiseptics and preservatives. They find application on a large scale in the industrial and medical sector, but also in private households. In terms of mass, the worldwide use of biocides exceeds that of antibiotics. Thus, despite their important role in preventing the spread of pathogens, due to their ubiquity, biocides are suspected to be drivers of the antimicrobial resistance crisis. In our work at BAM we try to understand how biocides contribute to the emergence of AMR, what the underlying adaptation principles and mechanisms are and how they compare to those found for antibiotics. Within our group, I mainly focus on the following two questions: How does phenotypic heterogeneity in bacteria affect the ability to survive treatment with biocides? And what are the consequences of phenotypic heterogeneity for the evolution of resistance to biocides and antibiotics? I will share published and unpublished results which demonstrate that phenotypic heterogeneity can enable the survival of biocide treatment and, through this, facilitate the evolution of AMR. On the other hand, we find that adaptation to a biocide can unexpectedly impair the ability to evolve resistance against an antibiotic.

This explicitly applies to the use of synthetic rubber granulate infill in artificial turf installations, which are complex multi-component systems consisting of multiple synthetic polymers (Fig. 1). In addition, abrasions of synthetic grass fibres and other turf components are also considered as MP sources. Although this has a major impact on public recreational sports, there is so far no sufficient data to estimate the MP emissions from artificial turf sports pitches into the environment and thus their relevance as a source of MP pollution. To close this gap, this study compared environmental contaminant emissions of three artificial turf scenarios at different ageing states (unaged, artificially and real-time aged): the past (old turf: fossil based, synthetic infill), present (most commonly installed in Germany: fossil based, EPDM infill) and future (turf with recycled grass fibres, no synthetic infill). Accelerated ageing by UV weathering and mechanical stress was carried out to simulate the outdoor weathering during the lifespan of approx. 15 years. MP emissions and released environmentally relevant contaminants posing a risk to the groundwater were simultaneously sampled using the newly developed Microplastic Eluate Lysimeter manufactured at BAM (Fig. 2). MP contents were analysed using smart microfilter crucibles (mesh size: 5 μm) with subsequent MP detection by TED-GC/MS. Additionally, concentrations of polycyclic aromatic hydrocarbons were determined using GC/MS and heavy metals using ICP-AES.

(water 50 to 100 ppmv, SO2 and NO2 ca. 100 ppmv) Corrosion rates increase with increasing water content. (0.2 – 20 mm/a) Condensation of acids and therefore droplet formation is always possible, even at low water contents. A low SO2 content within the CO2-stream might be more important than a low water content. Cr13-steels showed a general susceptibility to shallow pitting and pitting. So, they seem to be not suitable for CCUS applications. Low alloyed steels showed better corrosion behavior (predictable uniform corrosion). For direct contact with saline aquifer fluids only high alloyed steels shall be used.

MIC describes the negative effects a material can experience due to the presence of microorganisms. In Europe, several research groups/ other industrial stakeholders are already dealing with MIC. Unfortunately, the discussions are fragmented and the exchange of information is limited. A true transdisciplinary approach is hardly ever experienced, although this would be logical for this material/biology related challenge. USA, Canada and Australia have strong networks, and develop methods, prevention measures and standards, which Europe is forced to use, since nothing similar exists for a network and combined knowledge to design them according to european standards. This makes Europe extremely dependent and, in some cases, the potential measures or standards cannot been used because the suggested solutions are prohibited by European laws (e.g. use of biocides). Therefore, it is important to initiate a new European MIC-network. Europe needs to combine the efforts as experts in different fields and develop prevention measures according to the European rules, in close cooperation with industry and plant operators and owners of critical infrastructure. This COST Action will provide the necessary interaction and communication, knowledge sharing, training of personnel and of researchers of different disciplines. This will bring Europe to a leading role in this process, bringing ideas on an equal level with other nations, considering the values which are important for Europe and attitudes (e.g.environmental protection) and representing greater protection for people, property and the environment. The main aim and objective of the Action is to , in the context of MIC-research/control, encourage a fluent/synergistic collaboration/communication, closing the gap between materials scientists, engineers, microbiologists, chemists and integrity managers to encourage sufficient interaction between academia and industry. This Action will create a common MIC-Network, including the important stakeholders.

These surfaces are a natural habitat of subaerial rock biofilms (SAB) that are an important stage of primary succession. As their metabolic processes have a great impact on the composition of the near-surface layers of the earth biofilms on natural and manmade hard substrates are a research focus of geomicrobiology. In technical systems immobilized algae biofilms are already used successfully for wastewater cleaning. Algae can eliminate bacteria from the water and at the same time increase the oxygen concentration and the pH value in the water through photosynthesis, which again allows phosphate elimination to take place. Nitrificants contained in the algae biofilm convert ammonium to nitrite and nitrate. Mineral claddings for building facades could be engineered to sustain either natural or previously established carefully selected algae-dominated biofilms and this way help to clean the air. For a targeted engineering of the mineral substrates and the biofilms attached to them basic knowledge is however missing. By systematic research in an interdisciplinary team of microbiologists and building material scientists the following questions shall be clarified • How can a curated biofilm be stabilized on the surface and designed to be durable without compromising the substrate • What exactly do the biofilms need in terms of moisture in their respective growth stages? Or how long water must be available in what form and quantity to enable growth. • What is the influence of the substrate on the availability and quality of the (rain) water (water quality, leaching of substances (alkalis) from the building materials, leaching of aerosol components, surface tension, suction tension, thickness of the water molecule layers adsorbed in the pore spaces....) There are several research groups working on bioreceptive building materials which emphasizes the general interest in the topic. The idea of speeding-up the process by the targeted establishment of biofilms on building façade panels is a unique approach that has so far only been researched at BAM. Architects are very interested in biofilm facades as a new co-designing method of humans and nature reflecting the changing awareness for the loss of biodiversity in cities. If the biofilms need irrigation the evaporative cooling would reduce the urban heat island effect.

It is part of the RUNOFF-project, which studies and re-assesses the durability of roofing and facade materials under current atmospheric conditions in Germany. Studying building materials is important as they have a significant impact on achieving a variety of goals and targets within the sustainable developments goals (SDGs). The durability of materials is essential to reach sustainability. However, the durability of metallic materials is strongly depended on climate conditions, which have changed as a result of technical measures in industry, climate change and increasing urbanisation. In Germany at least, the data base is not up-to-date leading to prediction models regarding corrosion resistance and durability of metallic materials which can no longer be trusted and therefore need to be re-assessed and updated. Also, not only the demand for sustainable but also environmentally friendly building materials has increased dramatically. A number of construction materials produce chemical hazards, and therefore have negative impacts on water quality, soils health and ecosystems. To limit these impacts, environmental assessment methods and tools are needed to measure and quantify the inputs and outputs of building materials throughout their lifetime.

Given the widespread use of PFAS in various products, they are commonly found in groundwater near industrial and military sites in Germany and Israel. Moreover, recent regulations limiting the use of long chain PFAS have led industries to shift towards shorter chain alternatives. Hence, our efforts are geared towards refining detection, quantification, and removal methods for short and ultrashort chain PFAS. In terms of detection, ww are developing passive sampling devices capable of collecting and tracking the temporal distribution of PFAS species in groundwater. This will enable us to analyze contaminations in German and Israeli groundwater using cutting-edge analytical techniques. Additionally, contaminated groundwater will undergo a two-stage treatment process aimed at concentrating the relatively low PFAS concentrations using innovative membrane technologies such as closed-circuit reverse osmosis and mixed matrix composite nanofiltration membrane adsorbers. Subsequently, the streams containing higher PFAS concentrations will be treated through coagulation, with the remaining PFAS being adsorbed onto carbonaceous nanomaterials. The outcome of this research will include the creation of advanced tools for detecting, measuring, and eliminating PFAS from polluted groundwater, while also enhancing our understanding of the scope of these contaminations.

Darüber hinaus führten neue Vorschriften und Beschränkungen für die Verwendung von langkettigen PFAS zu einer vermehrten Produktion kurzkettiger Alternativen. Ultrakurzkettige PFAS (≥C3) können natürliche und anthropogene Barrieren durchdringen und schließlich in Trinkwasserquellen gelangen. Zudem entfernen die meisten gängigen Trinkwasser-aufbereitungsverfahren die ultrakurzkettigen PFAS nicht ausreichend. Im Kooperationsprojekt DEFEAT-PFAS wird daher das Ziel verfolgt, Wissenslücken über Nachweis, Quantifizierung und Entfernung von kurz- (C4-C7) und ultrakurzkettige (C1-C3) PFAS, in kontaminiertem Grundwasser zu schließen. Die israelischen und deutschen Projektpartner entwickeln dafür analytische Methoden and selektive Passivsammler, um das zeitliche Profil von PFAS-Spezies im Grundwasser zu erfassen und überwachen. Darüber hinaus ein zweistufiges Verfahren entwickelt, welches darauf ausgelegt ist, die relativ niedrigen PFAS-Konzentrationen im Grundwasser durch neuartige Membranverfahren, Umkehrosmose im Batchbetrieb mit geschlossenem Kreislauf sowie Verbund-Nanofiltrationsmembranen, zu konzentrieren. Anschließend werden die PFAS angereicherten Konzentrate mittels Koagulation behandelt und das verbleibende PFAS an kohlenstoffhaltigen Nanomaterialien adsorbiert.
