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).

Packaging recycling in EU member states – requirements from the circular economy package

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

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.

PlasticFreeDanube: Composition of macro-plastic waste in and along the Danube River

The reliable estimates are essential to developing measures to reduce plastic pollution and to make successes measurable and visible. For this reason, the cross-border project "PlasticFreeDanube" (PFD), which is co-financed by the European Regional Development Fund within the framework of Interreg Slovakia-Austria, aims to gain new knowledge on this topic for the Danube.

Influence of pre-screening before ballistic separation on NIR-sorting quality of plastic rich 3D-fractions out of MCW

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.

A powerful pair in plastics recycling: ANDRITZ’s latest shredder and separation technology
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The rising success of the plastics recycling sector has turned an environmental hazard – plastic waste – into a valuable resource. The constantly growing industry comes with increasing demands in terms of technology and quality, but also offers enormous potential for those who are ready to strike new paths. ANDRITZ has combined the latest shredder technology from its recently launched ADuro product line with an all-in-one solution for separating, washing and dewatering – the CENSOR ACZ decanter centrifuge. This powerful pair is perfect for processing various types of plastic waste, especially from household waste collection.

Applicability of multivariate data analysis to improve the sorting degree of recycled polyethylene

The Circular Plastic Alliance Declaration of the European Commission targets the us-age of 10 million tons of recycled plastic per year into new plastic products in Europe by 2025 (European Commission 9/20/2019). To assist this objective this work focuses on the improvement of mechanical sorting of polyethylene (PE).

Bio-based plastics in the post-consumer-recycling stream
© Wasteconsult International (5/2017)
The global production capacities of bio-based plastics register a constant increase, and the prognoses also confirm this upward trend. This results in a variety of products made of bio-based plastics that reach the established disposal streams as post-consumer wastes after being used.

Recycling of plastics – possibilities and limits

mtm plastics GmbH and mtm compact GmbH, which have been owned by the Borealis Group since 2016, have been recycling plastic waste since 1994. Today, mtm is among Europe’s technology leaders after changes in ownership and several phases of modernisation.
