The circular packaging design guideline and holistic sustainability assessment in circular economy© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The FH Campus Wien Circular Packaging Design Guideline provide recommendations for circular design for the whole supply chain. Circular design is a necessary prerequisite to achieve the goals of the European Circular Economy Package which requires full recyclability of packaging by 2030. Circular packaging should re-duce resource consumption and environmental impacts of packaging. The assessment of packaging sustainability requires the calculation of direct and indirect environmental impacts and circularity at the same time. A method for holistic sustainability assessment of packaging has been proposed by FH Campus Wien and developed in an ECR-working group (Efficient Consumer Response) with the participation of a number of companies along the whole supply chain (brand owners, retailers, packaging manufacturers and packaging systems).
Environmental-economic impact assessment of business models in the Austrian waste economy© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The dynamic macroeconomic one-region and multi-sector model WIFO.DYNK (dynamic new-Keynesian) was adapted to model the employment and value-added impacts of the Austrian waste economy in this respect. It is based on the most recent input-output tables of Statistics Austria.
Influence of pre-screening before ballistic separation on NIR-sorting quality of plastic rich 3D-fractions out of MCW© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The exploitation of plastics gains more importance over time. In this con-text, material recycling is especially focused on packaging plastics. A further waste stream that contains a significant amount of plastics is mixed commercial solid waste. To assess the potential of plastics for recycling and energy recovery from these waste stream large-scale experiments were conducted. The potential of mechanical pre-processing with the aim of generating a 3D-plastics pre-concentrate was assessed. The focus of these investigations was put on the relevance of the screening stage and its influence on down-stream material processing via ballistic separation and sensor-based sorting. Results demonstrate not only that the screening of the waste leads to enrichment of plastics in coarse particle size ranges (especially > 80 mm) and transfer of contaminants, organics and minerals to fine fractions (especially < 10 mm), but also that sensor-based sorting performance can be significantly enhanced due to cleaning effects on plastics, induced by the material circulation and friction in a drum screen.
Solid Recovered Fuel – Optimization of Plants in the Polish Economic Reality© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Waste management and district heating systems, especially in scope of smaller facilities, require a thorough modernization. In addition, the existing model of these systems, especially for small and medium-territorial units, is not able to meet new requirements of the EU policy in the field of resources and energy efficiency. It is therefore necessary to seek for the new model which quality will be closer to the requirements of the overall strategy of the European Commission, whose key elements includes the impact of the project on the social prosperity and the preservation of the principles of sustainable development.
Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
Producing solid recovered fuels (SRF) is a well-established route for recovering energy resources from municipal solid waste (household and/or commercial). Chloride content critically impacts the quality of SRF. It directly influences operation of thermal processes, having deleterious effects through the high temperature corrosion of the boilers and through demands placed on the flue gas treatment (FGT) system, which could impact emissions control. Whereas design and specification of process plant can mitigate the technical issues associated with the presence of chloride experienced during thermal treatment, processing such fuels is associated with increased capital, operating and maintenance costs. This, at best, restricts the uptake/use of SRF or increases the cost of its treatment towards achieving a reduced chloride content.
Development of Waste Management in the Arab Region© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
The Department of Waste Management and Material Flow of the University of Rostock has been active in Arab countries for over 20 years, and has initiated, carried out and scientifically supervised numerous projects. Waste management and material flow is an important theme in the field of German development cooperation in the MENA regions and has gained in significance in recent years.
Refuse Derived Fuel – A European Market Heading for Overcapacity© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
During the last five years, the residual waste market has been transformed from one whose geography was largely defined by a country’s borders to one that has become truly European in nature. Increasing, and now significant, tonnages of refuse derived fuel (RDF) and solid recovered fuel (SRF) are moving across national boundaries. In the UK, for example, the export of RDF and SRF has grown from 250,000 tonnes per annum (tpa) in 2011 to 3.4 million tpa in 2015.
Resource Efficiency in the German Steel Industry© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Recovery and recycling of metals from residues is important for protecting our natural resources. Therefore we identified approaches for the utilization of residues of the German steel industry to improve resource efficiency. The study focuses on the residues blast furnace sludge, basic oxygen
furnace dust/sludge and electric arc furnace (EAF) dust. The objective of the study was to find further, more efficient connections between process chains.
