Residual municipal waste composition analysis – New methods for Czech waste management
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Relevant information about MW composition and proper forecasting of MW composition is crucial for relevant technical and economical modelling and business planning in the field of waste management. These include techno-economical models of MW treatment units, e.g. sorting line, transfer station, energy recovery, waste collection and transport or a regional waste collection and treatment system modelling (Kropáč et al. 2018) and complex business models concerning specific investments in waste management. In this context, there is a project under the Ministry of Environment of the Czech Republic.

Environmental effects of fireworks with special consideration of plastic emissions

In Germany, about 133 million Euro are spent annually for New Year’s Eve fireworks, which result in 38,000 to 49,000 Mg of total firework mass. By a com-bination of desk research with official fireworks approval statistics, a customer survey, dismantling experiments with fireworks debris and with packaging characterisation, the total nationwide polymer emission was estimated to be 3,088 Mg. Out of this total mass, a projected polymer debris mass of 534 Mg was identified, and about 270 Mg of polymer packaging material. The remaining 2283 Mg of polymer mass are parts that eventually may remain at the launching site.

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).

Circular economy from an SDG perspective: A multi-stakeholder process for developing policy options
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Based on a longitudinal case study (the UniNEtZ project in Austria), which includes a multi-stakeholder involvement, we investigate the process of developing CE policies for the Austrian Federal Government from an SDG perspective. Within this context, the main research question is how multi-stakeholder processes can enable the development of CE policy options. The study thus contributes to providing a structured approach of how different stake-holders from academia, industry, research funding agencies and government collaborate, how knowledge is created and transferred within this multi-stakeholder process, and what outputs, outcomes and impacts can be realized at the national level in the context of developing CE policies using an SDG framework.

Packaging recycling in EU member states – requirements from the circular economy package
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The EU has established concrete recycling targets for packaging waste for 2025 and 2030. Furthermore, the methodology for calculating the corresponding recycling rates has been amended. The new and stricter calculation methodology will potentially lead to decreases of the current rates. This will be particularly the case for plastic packaging, where denkstatt calculated a gap far above 10 % compared to smaller decreases (> 2 %) to be expected for glass or steel packaging.

Collective research projects: Reviewing gaps in the recycling of multilayer flexible food packaging
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Recyclability and sustainability are conflicts in multilayer flexible food packaging, where material combinations (polymers, paper, aluminium) intend functionality. To increase the sustainability of multilayer flexible packaging through recyclable solutions, systemic and technical obstacles need to be considered. A holistic redesign approach, addressing food protection and the packaging’s end of life (collection, sorting, recycling) is essential to improve these already sustainable packaging solutions. To this, current collective research projects at the University of Applied Sciences, aim to closely link science and industry, promote research in the field of sustainable packaging and provide solutions to recycling goals of the European Union.

Life cycle assessment of waste wood used for energy production – Methodology and case studies
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
To assess the sustainability along the whole value chain, life cycle-based methodologies have been developed over the last years. Life Cycle Assessment (LCA) considers environmental impacts along supply chains, from extraction of raw materials to end-of-life of products (ASI 2006). The aim of this paper is to describe the use of LCA to assess the environmental impacts of the use of waste wood for energy production. Important methodological aspects on the use of LCA for the assessment of waste wood are presented using two different case studies from the H2020 projects STORY (Added value of STOrage in distribution sYstems) and TORERO (TORefying wood with Ethanol as a Renewable Output: large-scale demonstration).

State-of-the-art and future perspectives in textile recycling
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Today, the blending of materials within textiles is an asset in the design of protective clothing and various technical applications, but material mixes and blends also found their way into retail trade. The rise in end-of-life items is thus putting pressure on waste management to develop suitable recycling processes. Still, in the textile sector, waste prevention claimed by policy seems to be a pious wish.

Tex2Mat: The recycling of towels and laundry made from PET and cotton

The project “Tex2Mat” was a cooperation between companies working in the field of recycling or textiles and universities specializing in the field of polymer engineering and recycling. There were two polymers (PET and PA) examined and the whole project divided into two subprojects.

Digital and service transformation of business models - the case of ATM Recyclingsystems
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The trend of increasing digitalization and servitization affects all industrial companies in all sectors including the waste and recycling industry, as we will present in our case study. In this case, the company ATM Recyclingsystems implemented an IoT platform from t-matix with the goal, to provide customers with products that deliver the best efficiency and optimal cycle times.
