Environmental effects of fireworks with special consideration of plastic emissions
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
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).

Environmental-economic impact assessment of business models in the Austrian waste economy

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.

The potential of insects in waste management – an introduction to possible applications

In order to remain competitive for achieving a circular economy we need to consider even more alternative pathways to close the loop for material and waste streams down to a nutritional level. A sustainable and value adding strategy is the intensified rearing and use of insects, in particular the use of edible species as human food and animal feed.

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).

The use of electro-hydraulic comminution during mechanical treatment of secondary raw materials leads to a specific weakening of interfaces within the material.

Mechanical biological waste treatment plant for Bangalore west zone
© Wasteconsult International (5/2017)
Proper solid waste management is a problem in many developing countries, especially in their big cities. Wasteconsult International was developing a solution for the municipal waste processing for the West Zone district of the Indian mega-city Bangalore. For that purpose, studies regarding the quality and quantity of the waste had to be made first in order to decide which processing concept is the most favourable. Incineration and Mechanical-Biological treatment was taken into consideration. According to the attributions of the waste, MBT process with a convertible bio-drying and composting process was chosen and designed.

Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (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.

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.
