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).

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.

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.

Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (9/2016)
The waste disposal system in Poland is one of the least advanced in Europe. Despite great efforts over the last 20 years municipal waste landfilling has only reduced from 95 percent in 1991 to 73 percent in 2010. This still means that millions of tonnes of post-consumer waste continue to be landfilled.

Fully Automated Sorting Plant for Municipal Solid Waste in Oslo with Recovery of Metals, Plastics, Paper and Refuse Derived Fuel
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (9/2016)
In order to treat household waste Romerike Avfallsforedling (ROAF) located in Skedsmorkorset north of Oslo, Norway required the installation of a mechanical Treatment facility to process 40,000 tpa. Together with a Norwegian based technical consultancy Mepex and German based technical consultancy EUG the project was tendered and the plant build against a technical specification. In 2013 the project was awarded to Stadler Anlagenbau and since April 2014 the plant is in operation with an hourly throughput of thirty tons. The input waste contains specific green coloured bags containing food waste which is collected together with the residual waste from the households. The process recovers successfully the green food bags before the remaining waste is mechanically pre-treated and screened to isolate a polymer rich fraction which is then fully segregated via NIR technology in to target polymers prior to fully automated product baling. Recoverable Fibre is optically targeted as well as ferrous and non-ferrous metals. All food waste is transported off site for further biological treatment and the remaining residual waste leaves site for thermal recovery. In 2015 the plant has been successfully upgraded to forty tons per hour and remains fully automated including material baling.

Heavy Metals Flows Induced by Plastics Utilisation in the Blast Furnace Process
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Waste plastics can be utilised as an alternative reducing agent in the blast furnace process. There they are substituting for reducing agents such as coke, crude tar or heavy crude oil, for example. However, the utilisation of waste plastics as an alternative reducing agent is also associated with an additional input of heavy metals in the process. These heavy metals are not only relevant for the process stability and the product quality but also from an environmental Point of view. To which extent gaseous emissions or waste water from furnace gas cleaning may be influenced by feedstock recycling of waste plastics has been hardly investigated so far.

This report gives a technological description of the four common collection and recycling schemes that have been tested in the Netherlands as part of the pilot beverage cartons in 2013. During this pilot the collection and recycling of beverage cartons was tested in 37 different municipalities, with various separate collection systems and 2 recovery facilities.
