Wechselberger, Viktoria in OpenAIREBiogas bzw. das daraus gewinnbare Biomethan ist ein erneuerbarer Energieträger, der zur Erzeugung von Strom und/oder Wärme, als Kraftstoff oder Erdgassubstitut dient. Die Biogaserzeugung wird daher als nachhaltige Strategie zur Minderung von anthropogenen Treibhausgasen beschrieben. Eineindeutig positiver Umweltnutzen ist jedoch insbesondere von den Prozess- bzw. Lagerungsemissionen sowie den technischen Verlusten bei der Nutzung oder Aufbereitung des produzierten Biogases abhängig. Die Evaluierung bzw. Minimierung der prozessbedingten Treibhausgasemissionen (insbesondere der Methanemissionen) ist daher ein wesentlicher Schritt, um die Nachhaltigkeit der Biogasindustrie zu fördern, Methan (CH4) ist ein äußerst starkes Treibhausgas, das etwa 80-mal klimaschädlicher ist als Kohlendioxid über einen Zeitraum von 20 Jahren.

The production and use of engineered nanomaterials and nano-enabled products is increasing, enabling innovations in many application areas, e.g., in the sector of food contact materials. However, nanosafety-relevant information for chemical risk assessment is still scarce, leading to a high level of uncertainty and making the early integration of safety to the innovation process indispensable. This study analyzed the strengths, weaknesses, and applicability of the nano-specific Safe-by-Design (SbD) concept using nanoclay-containing polymer coffee capsules as a theoretical case study. In addition, a material flow analysis was conducted to identify exposure pathways and potential risks, and a multi-stakeholder approach was applied to discursively discuss challenges when attempting to combine safety and innovation at an early stage. The results indicate that the SbD concept is generally welcomed by all stakeholders, but there is a lack of clear rules on the transfer of information between the actors involved. Furthermore, a voluntary, practical application usually requires in-depth knowledge of nanotechnology and often additional financial efforts. Therefore, incentives need to be created, as there is currently no obvious added value from a company’s point of view. The SbD concept should be further developed, standardized, and integrated into existing legal frameworks to be implemented effectively.

This study examines methane (CH4) emission factors from biogas and wastewater treatment plants, based on primary and secondary data collected from 109 facilities. Primary emission data were measured at 19 facilities representing prevalent plant configurations across Europe. Statistical analysis highlights two categorical variables, namely primary feedstock and plant size, expressed as CH4 production (≤250 kgh-1: small and medium-sized plants, >250 kgh-1: large plants), each of which has a significant impact on whole-site CH4 emissions. Additionally, digestate storage (gastight vs. not-gastight) has a meaningful effect when considering CH4 production as a continuous variable in the statistical analysis. Our results indicate that wastewater treatment plants have the highest average CH4 losses (7.0 % of CH4 produced, n = 31 or 0.10 kgpopulation equivalent(PE)-1yr-1, n = 28), followed by manure-based plants (3.7 %, n = 49), biowaste treatment facilities (2.8 %, n = 11) and energy crop-processing plants (1.9 %, n = 14). Furthermore, small and medium-sized plants have elevated emissions (5.6 %, n = 67) compared to larger counterparts (2.2 %, n = 42), primarily attributed to the absence of gastight digestate storage. Emissions tend to be lower with gastight digestate storage (2.7 %, n = 61) than not-gastight storage options (6.2 %, n = 48). Emission factors were determined for normal operating conditions, with a further investigation into other-than-normal operating conditions revealing temporal or constant emission peaks in eight out of 19 facilities. These peaks, suggesting potential areas for targeted mitigation strategies, were attributed to pressure relief valves, flare ignition problems and major leakages.
