Integration of regional socio-economic LCA and environmental LCA for the assessment of industrial bioeconomy networks
The current geopolitical situation in Europe has led to revisit the evaluation of energetic independence of countries but also of regions. In this sense, previous works have shown the advantages of implementing regional integration schemes for bio-based production systems to promote the internal exchange of heat and by-products (Hildebrandt et al., 2020) (Bijon et al., 2022; Fytili & Zabaniotou, 2022).
This work presents the socio-economic and environmental life cycle evaluation ofalternative defossilization pathways for a bio-based industrial network in the Central Germanyregion. The pathways were defined considering the potential energy utilization of regionally availablebiomass residual streams. The evaluation has been made using an integrated approach, i.e.using a traditional life cycle assessment methodology, complemented by a regionalized socioeconomiclife cycle assessment, utilizing the “RESPONSA” framework developed at UFZ. It hasbeen shown that the environmental advantages of the defossilization of the value chain add upto 5% of the reduction of the overall impacts, which was somehow expected due to the alreadyexisting integration and optimization in the value chain. The socio-economic results, however,show that the path to defossilization can provide a clear enhancement of the regional socio-economic impacts, which can be of great value to the bioeconomy sector.

Von der linearen Abfallwirtschaft zur Circular Economy in Brasilien
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
Brasilien verfügt seit 2010 über eine fortschrittliche Abfallpolitik, die im Frühjahr 2022 im Umsetzungsplan PLANARES um ambitionierte Recyclingquoten ergänzt wurde. Der Umsetzungsplan sieht u.a. eine Recyclingquote für Wertstoffe von 20 % bis 2040 vor, was einer Vervierfachung des aktuellen Wertes entspricht. Dies stellt die für die Abfallwirtschaft zuständigen Kommunen vor große Herausforderungen. Regionale und nachhaltige Abfallwirtschaftskonzepte, die lokale Rahmenbedingungen berücksichtigen und auf die Herstellung von Sekundärrohstoffen abzielen, sind Teil der Lösung und tragen zur Erreichung der Recyclingziele bei. Diese Konzepte bestehen aus verschiedenen Technologiekombinationen, die fraktionsspezifisch und nach definierten Kriterien geplant werden müssen. Für eine effektive und effiziente Planung sollten Maßnahmen in den Bereichen Technisierung, Modularität, Standorte und Dynamiken berücksichtigt werden.
Comparative analysis of the industrial dust efficiency use as a filler in building composite materials
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
The article presents a comparison of the characteristics of several types of
industrial dusts in terms of their use as a filler in polymer compositions. To confirm the possibility of using the studied waste, their material composition and properties were studied. The paper presents studies on the processing of industrial dusts into polymer composite materials for construction purposes. The characteristics of the developed composite materials have been studied. The influence on the strength characteristics of composite materials of the shape of dust particles, their size distribution, the value of the specific surface area, and the maximum packing density of particles is determined. The prospects for the use of dispersed mineral waste for the production of building composite materials are considered.
The AHOY-Project: Waste Wood Sorting with X-ray Technology
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
Waste wood is a valuable resource, but is hardly recycled despite increasing demand, predicted supply gaps (Mantau et al. 2010), and galloping wood prices since 2020 (Trading Economics 2022). In Germany alone around 10 million tons of waste wood accumulated in 2016. Only a minor part (1.7 million tons) is substantially reused in the production of chipboards. The majority (7.7 million tons) is fed into energy recovery, i.e., burned in one of the 80 German waste wood power plants (BMUV 2021), and is thus lost, while the supply of fresh wood is limited by slow growth cycles and finite acreage. In view of current environmental regulations, climate change and massive tree mortality, waste wood should be kept permanently in the circular economy as a high-quality raw material in the future.
Refine the circular economy by rethinking it - a holistic approach for the advanced circular economy
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
The Circular Economy is a recent economic approach aiming to transform the linear economy into a sustainable system including the economic, ecological, and social dimensions. The transformation faces various barriers and obstacles, each in a different field inside the value system. Three different (sub-system) approaches were developed independently to address those hurdles and provide solutions to mitigate them. The paper will briefly describe those approaches, including their strengths and weaknesses. Out of each of the three individual sub-systems, these sub-systems are combined in a holistic approach and presented as the Advanced Circular Economy. The system is developed on a meta-level. Nevertheless, a very crucial example, namely traction batteries for electric vehicles, will be given to show the relevance of the system within the current economic surroundings and explain the overall system of the Advanced Circular Economy.
Fundamental drying experiments with processed residual municipal solid waste materials
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
Waste management companies and municipalities in southwestern Hungary aim the fulfillment of the EU’s target, namely to decrease landfilling below 10 % and increase recycling above 65 % of municipal solid wastes. However selective collection is continuously improved there is still high amount of residual MSW is generated. A new mechanical RMSW processing plant (20 t/h) and an experimental RDF pyrolysis plant (200 kg/h) had been built (Faitli et al. 2020) and now extensive research is being carried out to solve the local utilization of the bio-fraction and the RDF. This is the reason why this fundamental drying research was necessary. Dryer classification and the selection of the best solid waste drying techniques vary significantly due to the vast range of waste to be dried and the inherent challenges of dealing with non-standardized systems. In general, biomass dryers may be categorized according to their heat transmission technique and the physical qualities of wet particles.
