“…In a tendering competition, primary or secondary treatment plants provide a treatment offer on the condition they have capacity available. Available capacity is defined as 90% of total plant capacity reduced by pending treatment contract volumes and capacities blocked by system external waste fractions such as bulky waste (SWB, 2020; UBA, 2018c; Voss et al., 2021; Wolfersdorf et al., 2017). Blocked capacity (cf.…”

Chemical recycling (CR) could support a circular approach for municipal solid waste (MSW) treatment. In promoting the recirculation of recyclable carbon-containing waste as secondary feedstock for chemical production, it could contribute to resource conservation, emissions reduction, and supply security. To evaluate CR's contribution to the transition from a linear to a circular carbon economy-and correspondingly to the achievement of environmental, economic, and social sustainability as indicated in the UN Sustainable Development Goals (UN-SDGs)-this study builds on extant literature of life cycle sustainability assessment (LCSA) to investigate consequential environmental, economic, and social CR impacts. Specifically, an integrated approach whereby process-based life cycle assessment, techno-economic analysis, and social indicators are linked in the framework of an agent-based model is developed to investigate sustainability consequences of CR via gasification of residual MSW in Germany.Results suggest that CR contributes to reducing climate change and to addressing terrestrial acidification and fossil resource scarcity. However, its deployment will be associated with significant system costs. Hence, to promote CR implementation, measures such as obliging direct waste incineration to trade CO 2 certificates-provided that certificate prices increase sharply in the future-as well as implementing a recycling rate are found to be necessary to gap economic disadvantages. This study not only contributes to extending life cycle approaches for LCSA methodologically, it furthermore provides valuable insights into temporal and spatial interactions in waste management systems to inform science, industry, and politics about the sustainability impacts of CR on the achievement of the UN-SDGs. This article met the requirements for a gold-gold JIE data openness badge described at http://jie.click/badges.

“…Der Anteil an kohlebasierter Methanolerzeugung liegt mittlerweile (Stand 2013), hauptsächlich bedingt durch den hohen Anteil in China, bei ca. 39 % an der gesamten Methanolproduktion [4][5][6]. Für die CO-basierte Methanolsynthese sollte das Synthesegasmodul (Verhältnis (H 2 -CO 2 ):(CO + CO 2 ) in mol mol -1 ) im Bereich von 2,05 bis 2,10 liegen und eine Mindest-CO 2 -Konzentration von ca.…”

Zur Herstellung emissionsarmer synthetischer Ottokraftstoffe mit optimierter Qualität aus regenerativem Methanol erfolgten im Rahmen des Kopernikus-Verbundvorhabens ,,Power-to-X'' Katalysator-und Prozessoptimierungen. Hierzu wurden eine Laborversuchsanlage mit Festbettreaktor entsprechend der weiterentwickelten STF-Technologie STF+ errichtet und Versuche mit verschiedenen Katalysatoren und Einsatzstoffen sowie einem breiten Spektrum an Prozessparametern durchgeführt. Die präzise einstellbaren isothermen Synthesebedingungen ermöglichen die gezielte Einstellung der chemischen Eigenschaften der erzeugten hochoktanigen Ottokraftstoffe.For synthesis of emission-reduced gasoline fuels from regenerative methanol, catalyst and process optimization was carried out as part of the joint research project Kopernikus ,,Power-to-X''. For this purpose, a laboratory test plant had to be designed and commissioned, and process parameters for an optimized fuel quality had to be worked out considering variations of catalyst and feed. The precisely adjustable isothermal synthesis conditions allow the specific adjustment of the chemical properties of the high-octane petrol produced.Abbildung 4.
