Ermittlung der Rückgewinnungspotentiale von metallischen Rohstoffen aus dem Nichtwohngebäudebestand

Non-residential buildings are often very complex and contain a lot of metals. Copper, steel, iron, aluminium and lead come with construction but also installation of machinery and equipment. Current deconstruction methods record metals separately, if metals occur purely. If metals are only a minor part of a composite material, they may be dumped with the main material and lost. Information as to the degree of separate collection of the metal inventories of buildings is lacking up to now.

In our research, we investigate the material stock of buildings and related dominant factors like age of the building, the original purpose it was built for, later forms of use, and alterations with building use changes or renovations. These factors are explored on industrial and commercial buildings in the Rhine-Main region. In a second step, we study the questions if it will be possible to avoid the loss or to minimize it economically? The potentials determined exemplarily for each metal will be converted into characteristic numbers for the building, construction and renovation – year and type respective. These numbers will form the basis for a "mapping" of metals in the Rhine-Main region.

Steel Slag Asphalt: Preventing the Waste of a High Quality Resource
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Steel slag is the inevitable by-product of the production of steel, from both the conversion of iron to steel and the recycling of steel scrap. Historically, this material has been sent to a landfi ll as waste, but over the last 100 years or so, a variety of uses have been found for what has proven to be a high quality, valuable resource. With this in mind, the steel industry within Europe now consider iron and steel slag to be products and not waste and as such have registered the materials under Reach (Registration, Evaluation Authorization and Restriction of Chemicals). Steel slag is formed by the addition of lime to the molten metal in order to remove impurities and to control the quality of the steel. The resultant slag is a complex mineral formed from oxides of calcium, aluminium, silicon and magnesium along with various other trace elements. Once cooled, the slag forms a crystalline rock that can be used as a replacement for natural aggregate in a variety of construction products, including asphalt. This paper specifi cally focuses on the use of steel slag as aggregate for asphalt mixtures in road construction and addresses the processing and quality control of the slag, along with its properties and the benefit of these properties for Asphalt materials.

Effiziente Verwertung von Tunnelausbruch durch Einsatz neuer Technologien
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Der Beitrag behandelt die Wiederverwertung von Tunnelausbruchmaterial, was in Anbetracht stetiger Rohstoffverknappung ein Gebot der Stunde ist, das es sowohl von Auftraggebern, Planern, Baufirmen, als auch dem Gesetzgeber selbst zu verfolgen gilt. Neben der Schaffung einer rechtlichen Situation, die eine effiziente und unbürokratische Verwertung ermöglicht, sind auch technische Weiterentwicklungen in Bezug auf eine Materialanalyse gefordert, die eine Charakterisierung des Ausbruchmaterials noch auf der Tunnelbaumaschine (TBM) in Echtzeit nach den für eine Verwertung entscheidenden Parametern ermöglicht. Die Verknüpfung dieser Resultate mit einer Rohmaterialdatenbank, die mit den Ergebnissen der Materialanalyse gespeist wird, stellt den Schritt zu einem modernen, webbasierten Handel mit mineralischen Rohstoffen dar.

Elektrodynamische Fragmentierung von Betonabbruch
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Bisher wird das Potenzial des Betonabbruchs zu wenig genutzt. Dort wo recycelt wird, findet meist ein minderwertiger Einsatz statt, z.B. wird der aufbereitete Betonabbruch aus dem Hochbau als Kofferung im Strassenbau eingesetzt. Feine Fraktionen (< 4 mm) werden teilweise auch deponiert, da diese verhältnismässig viel Zement enthalten.

New Sampling Technique for Coarse Waste Materials from Bales
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Environmental analysis has to deal with the possible sources of error. It is known that the process of sampling is the major source of error (up to 90 % of the total error). The sampling error is scarcely considered, while the insignificant analysis error is included with up to three decimals. However, there are not yet any effective methods to reduce the sampling error, mainly because of the inhomogeneous properties of waste. The aim of the project was to improve the sampling process with the same or an even higher accuracy of the analysis results.

Fully Automated Sorting Plant for Municipal Solid Waste in Oslo with Recovery of Metals, Plastics, Paper and Refuse Derived Fuel
© TK Verlag - Fachverlag für 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.
