The voestalpine Group's High Performance Metals Division is globally known for producing high-quality steels using well defined combinations of alloy elements and sophisticated production techniques. What makes these steels special is the set of exceptional properties such as resistance to corrosion and heat, high purity, and extreme durability that makes our products suitable for diverse applications, from aviation to construction of turbine blades and high pressure die casting tools.

Value Chain Optimization for Metal Recycling Processes through Probabilistic Modeling
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
Optimizing the value chain in metal recycling processes presents significant challenges due to the complex nature of defining processes and the limited availability of sensor technologies capable of continuous monitoring (Golev & Corder 2016). Metal recycling remains at the forefront of industries advancing through expert knowledge and process simulation (Reuter et al. 2013).

How will tramp elements affect future steel recycling in Europe?
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
Global steel production has grown massively since the Second World War. In recent decades, however, the steel market has become saturated in affluent regions such as the US and the EU. This has resulted in stagnate steel production and increased quantities of old scrap. The increasing shares of post-consumer scrap offer the opportunity to increase the share of scrap in crude steel production.

Reuse of building components

Cities and buildings are urban mines for raw materials and bind large quantities of valuable resources for various periods of time. In addition to the common recycling activities, primarily for mineral construction residues, a market for well-preserved 2nd hand structural components and materials is emerging.

Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –
© ThomĂ©-Kozmiensky Verlag GmbH (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
© ThomĂ©-Kozmiensky Verlag GmbH (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.

DIRECT-MAT – developing best practice on recycling or safe disposal of road materials in Europe
© Wasteconsult International (6/2010)
The European road network has a total length of more than 5.8 million km (ERF 2007) and it is still growing. Obviously, various pavement layers exhibit different lifetimes which makes regular maintenance work necessary. As a result, several hundred million tons of road materials are excavated each year from a number of demolished pavement layers. According to European policy (EUROPEAN PARLIAMENT, 2006), these materials can be seen as wastes, viz. “substance or object which the holder discards or intends or is required to discard”. Nevertheless, in nearly all countries, part of these road construction wastes is reused or recycled back into road infrastructure and this part may reach 100 % depending on the type of road waste.

DeconRCM: A decision support system tool for renovation and demolition waste management
© Aristotle University of Thessaloniki (6/2009)
The absence of a certified network for the collection and processing of the materials contained in generated Renovation and Demolition (R&D) waste is a main shortcoming of R&D waste management in Greece. Until recently, less than 5% of all R&D waste generated in Greece was reused or recycled, while the rest was landfilled or disposed in uncontrolled, open dumps. In order to increase the community’s awareness in environmental issues a research team has been formed and qualified for the funding of the project “Information System for Demolition Waste Management” (DEWAM project).

Investigation on material separation of mixed construction and demolition waste by sorting process
© Aristotle University of Thessaloniki (6/2009)
The final disposal ratio of mixed construction and demolition waste (MCDW) remains high in Japan, while progress has been made in the recycling of other construction and demolition waste. Sorting facilities are expected to play an important role in better management of MCDW. In this study, the feasibility of sorting facilities for the separation of material and of pre-treatment for final disposal was investigated by conducting a batch experiment at an operational facility.
