It is impossible to imagine today’s society and economy without plastic and plastic packaging is in particular focus. Worldwide, 368 million tons of plastic were produced in 2019, of which 57.9 million tons in the European Union (EU). They account for more than a third of all plastic products in Europe and are particularly conspicuous because of their short lifespan and ubiquitous distribution in the environment worldwide. (Plastic Europe 2020) According to Eurostat, plastic packaging is accountable for 15.4 million tons or 177.4 kg of waste plastic packaging per citizen in 2019 (Eurostat 2021). Hence, the proliferation of plastic in all areas of life has become an increasingly
visible issue and its impact on the environment is the subject of heated debate.

Regulations on the European level already address this issue. Due to limits of physicalproperties of single material packaging, multilayer films are on the rise. These complex stackedstructures of up to nine thin different layers pose a new challenge to waste management systems,especially when sorting post-consumer plastic packaging. Their share in plastic packaging is stillunder vivid scientific discussion. The presented research provides evidence that the multilayerfilm content of the two-dimensional fraction of separately collected plastic packaging is about 24 w-%, or an estimated total of 6 w-% for the overall Austrian separately collected waste stream, respectively.

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.
Integration of regional socio-economic LCA and environmental LCA for the assessment of industrial bioeconomy networks
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
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).
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.
