:metabolon - From Waste to Resource Lindlar: From waste to resource :metabolon turns landfill into an innovation site
When the Leppe landfill was designated for follow-up use, the :metabolon project was expanded to form a European Centre of Resources Management as part of the structural funding programme of the state of North Rhine-Westphalia (Regionale 2010). The body responsible for the project is the waste management association Bergischer Abfallwirtschaftsverband, which developed the location into a competence, learning and innovation centre for material conversion and site-related environmental technology and techniques. This was done jointly with Oberbergisch region, the Rheinisch-Bergisch region and the municipalities of Engelskirchen and Lindlar. Existing competencies were integrated, developed further and presented in a new light.

Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Sequential Extraction as a Method for Analysis of Heavy Metals Mobility in SoilsSusana Casaseca, Dr. Martin Wellacher
Polluted soil with metals could affect human health through direct contact with soil, but potentially greater threats could rise, for example, from infiltration of the metals into groundwater aquifers or by the plant uptake of those. The hazard in soil attributable to metals is often assessed by determination of their total content or pseudo-total content in soil.

Dr. mont. Renato Sarc, Univ.-Prof. DI Dr. mont. Roland Pomberger, Ing. Andreas Zöscher
During the last years, noticeable changes in the availability of mineral raw materials (e.g. ores, coal) were observed due to an enormous raw material demand of developing countries (e.g. China). Subsequently, a sensible scarcity of raw materials, highly competitive markets and a significant aggravated accessibility to mineral resources have been noticed.

During the first half of the 20th century, several different dumping sites, distributed in two different town districts of Leoben, were used for the disposal of collected municipal solid waste.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben RoadMap - Mapping in Case of Landfill MiningDr. Jörg Nispel, Prof. Dr. habil. Stefan A. Gäth
Raw materials such as steel and energy are becoming scarcer due to the steady growth of the world population and the resulting consumption change. Hence, it is to be expected that the Prices of primary and secondary raw materials will rise in future even more than present.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Material Recycling of Polyolefin-Rich Plastic FractionsMarkus Lehner, Wolfgang Hofer
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.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Two Case Studies on Landfill Mining: Kössen (Austria), Bishkek (Kyrgyzstan)Dipl.-Ing. Martin Steiner, Marion Fuchs, Martin Rottler
The case study on Kössen describes a hands-on assessment of the content of a former landfill which was performed prior to fi nal excavation works according to the principle “let´s assume assumptions by knowledgeâ€. The case study on Bishkek describes mining techniques applied in many landfi lls in Central Asia in former, partly decomposed disposal zones from the “Sovjet Eraâ€, but gives also impressions on general landfi lling practices and standards in the region.

During the processing of solid waste for the recovery of valuable materials certain residual fractions are inevitably created. As a rule, these cannot be processed at state-of-the-art solid waste processing technology for economic reasons and for quality restraints.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Primary Gravel Production at Industrial LocationsStefan Kreuzwieser, Stefan Prentner
The consortium ARGE GROUND UNIT produces CE-certified gravel and sand from contaminated excavated materials in a wet separation plant on the area of voestalpine Stahl GmbH. The products are used as aggregate for concrete and for unbound and hydraulically bound base layers. The treated materials come from various construction projects on the site of voestalpine in Linz. This area is industrially used since nearly 100 years. The material contains typical pollutions from steel production of former decades. Without treatment in the separation plant of ARGE GROUND UNIT, it would be necessary to carry nearly all excavations to a landfill.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Removal of H2S from Biogas with the Use of AshesMag. Peter Mostbauer, Dipl.-Ing. Alexander Knapp, H. Insam
In 2007, the Institute of Waste Management, Vienna, proposed a rather simple static system for removal of CO2 and H2S from biogas or landfill gas (LFG). Aged MSWI bottom ash was used as a “filter mediumâ€ at that time (BABIU process). The publications available today about ash-based upgrading of biogas concentrate on CO2 removal, CH4 enrichment and ecological benefits of the process. Less attention has been paid to reactions of H2S with ash constituents.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben CHP-Units with Stirling Engines for Landfi ll Gas UtilizationDr.-Ing. Arnd Seyfert
Stirling engines have been used for about 200 years. For example at the beginning of the 20-th century 250,000 stirling engines were used as mechanical drives for ventilators, water pumps and drives for small devices for example sawing machines. But there are some disadvantageous in comparison with the normal combustion engine (for example the smaller electrical efficiency,
the lower rotational-speed and a worse power to-weight ratio) so that the stirling engine lost this
competition and nearly disappeared from the market.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Security Risk of Landfill Gas - Hazard Potential and Defensive MeasuresDr. Roman Prantl, Klaus Schloffer
The present work “Security Risk of Landfill Gasâ€ has the goal to analyze, identify and minimize risks and hazards resulting from the emergence of landfi ll gas through a comprehensive approach. The fact that accidents happen repeatedly in this area, shows the security policy defi cit and thus the relevance of this work.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Application of Unmanned Aerial Vehicle Technologies in Design and Operation of LandfillsJohannes Novak, MSc Daniel Söderlindh, DI Dr. Arne Michael Ragossnig, Michaela Ragossnig-Angst
Design and construction as well as the managing of landfills rely on a variety of land surveying data as well as other geo-information. For the design phase the suitability of the specific site acc. to the criteria defined in the Austrian landfill ordinance, knowledge of the topography as well as the boundary conditions with regard of immission control for neighbours require utmost attention.

The landfi ll Rautenweg is the largest landfill in Austria and operated by the city of Vienna. The landfi ll is sealed by so-called “Wiener Dichtwandkammersystem“ (Vienna Cutt-Off Chamber). The system comprises two parallel diaphragm walls embedded into the impermeable stratum by 25 m. Counterfort are placed between the two diaphragm walls in regular intervals.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Aeration of the Landfill Pill; Effects on Groundwater ContaminationDr. Ing. Klemens Finsterwalder
At the former landfill Pill in Tyrol, Austria groundwater contamination was caused by high Ammonium loads of up to 20 mg/l. Biodegradable nitrogen was specified as the cause of groundwater pollution by ammonium. However, other substances were hardly noticeable. Ammonium is generated within the landfill body through anaerobic decomposition of organic matter.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben In-situ Aeration: Performance Control after 5 Years on a Municipal Solid Waste LandfillDipl.-Ing. Dr. Marion Huber-Humer, Marlies Hrad, Dipl.-Ing. Sabine Lenz
By converting anaerobic landfills into an aerobic, biologically stabilised state through accelerating organic matter degradation, the time and effort necessary for post-closure management can be shortened. In-situ landfill aeration is thereby a promising cost-efficient treatment method to significantly reduce environmentally relevant and current emissions from existing municipial solid waste landfills (MSW), to stabilise the organic waste material, and to reduce the Emission potential.
