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.

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.

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.

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).

Development of local municipal solid waste management in the Western Transdanubia region of Hungary

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.

Material Recycling of Polyolefin-Rich Plastic Fractions

The material recycling of plastic waste has still an enormous potential, even in countries like Austria or Germany, which have a highly developed waste treatment system. At the moment, approximately 2/3 of the utilized packaging plastics are treated thermally, i.e. as waste derived fuels, and only 1/3 are routed for material recycling.

Implementation of a Recovery System with Optimized Interfaces - The Total Plastic Concept

The German system for recovery of mixed dry recyclables has been established in the early 90s. It was installed to increase the recycling rates additional to the already existing system: the separate collection of papaer and glass.

Plastic Waste Recovery in Spain - Overview of the Market and Applied Technologies
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (10/2012)
Plastic consumption in different Spanish industrial sectors was 2.840.000 tonnes in 2010 and generated approxomately 2.206.000 tonnes of plastic waste in 2010. About 23% of this waste was recycled and 17% recovered, being landfilled about 60% [2].
