: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.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Reducing Leachate Treatment Costs, But How?Dr. Christian Schröder
Leachate processing at landfills places significant demands on process technology. Landfill leachate contains a cocktail of various pollutants. In addition to biodegradable nitrogen compounds, this also includes a large number of other organic and inorganic pollutant groups that are fully or partially non-biodegradable. These substances have to be removed from the landfill leachate through cost-intensive physicochemical treatment. The requirements placed on the treated leachate depend on the way it is discharged. Legal framework specifications define the limits for direct or indirect dischargers.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben A New Methodical Approach for Environmental Impact Assessment (EIA) Related to MSW Landfills in RussiaEkaterina Zyryanova, Olga Ulanova
Nowadays, the most widespread method of MSW disposal in Russia is landfilling, using the most primitive landfilling technology. On an average, only 3-4 % of municipal solid waste is recycled, but the majority of waste is taken to dumps — there are about 11 thousand in Russia with an area of more than 11,000 hectares of land. About 82 billion tons of waste is buried in them. This fact requires that a full-fledged and accurate assessment of this activity and its influence on Environment has to be carried out before its implementation.

Nowadays, gasification of waste or biomass is becoming the great interest all over the world. Especially, gasification of municipal solid waste (MSW) has been well-researched in Japan. The development of MSW gasification technology was started in the 1970s in Japan because of oil crisis. Several technologies have been researched and developed. The Direct Melting System (DMS), which is the gasification and melting technology developed by Nippon Steel & Sumikin Engineering Co., Ltd., is one of the developed waste gasification technologies in this era. This technology was introduced for commercial use in Kamaishi City, Japan in 1979. As well as this waste technology, other gasification technologies have been developed for commercial use and installed.
TK Verlag - Fachverlag für Kreislaufwirtschaft Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –Dr.-Ing. Kazimierz Borkowski
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.
Wasteconsult international Comparison of MBT plants with and without upstream Anaerobic Digestion (AD) in terms of moisture Management and achievement of landfill disposal criteriaAurel Lübke, M.Sc. Roman Lugmayr
In waste industry the trend has developed to treat municipal solid waste (MSW) within an anaerobic digestion process. For this purpose MBT plants with an upstream AD plant were built. In the context of plant monitoring and trials one MBT with AD and one MBT without AD were examined and compared to determine the impact of the AD process. For this, the plant operation, especially the moisture management, the compliance of the landfill criteria and also the economic efficiency of the MBT were investigated.
Wasteconsult international Landfill mining option: MBT role and landfill potential dangerDr.-Ing. Dipl. Elena Cristina Rada, Dr.-Ing. Dipl. Marco Ragazzi, Prof. Dr.-Ing. Vincenzo Torretta, Ing. Giorgia Passamani
The use of landfills for the disposal of municipal solid waste (MSW) has many technical and regulatory limits. An interesting solution is to recover the bales that have been previously stored in a landfill. After specific mechanical biological treatments (MBT), the contents of the bales can be used to produce a solid recovered fuel (SRF) that can be used for energy purposes. The possibility of producing SRF fuels from a landfill in northern Italy has been studied and is presented in this paper. The MSW extracted from the landfill, the bio-dried material produced by the waste hypothetically treated in a plant for bio-drying, and the SRF obtained after the extraction of inert materials, metals and glass from the bio-dried material have been characterized. Assessed the waste nature, the potential environmental impact of dioxin release from a possible landfill fire has been analysed, applying the Austal2000 model system.
Wasteconsult international MBT demonstration project in TunisiaThouraya Chantou, Ayman Elnaas, Dr.-Ing. Abdallah Nassour, Bernd Hasel, Dr.-Ing. Wolfgang Pfaff-Simoneit
Tunisian waste is rich in organic and hence fairly wet. This causes technical Problems and adverse environmental effects when landfilled. But next to the formation of leachate and landfill gas also operation problems were observed especially at pit landfills because of unsufficient drainage of the leachate which resulted in situations that the whole waste is soaked with leachate and hence the mechanical stability is reduced. The main objective of the pilot test was to prove that the PMB is a feasible solution for the conditions in Tunisia and an adequate option to overcome some of the Problems mentioned above.
Wasteconsult international Case study of an MBT producing SRF for cement kiln cocombustion, coupled with a bioreactor landfill for process residuesMario Grosso, L. Rigamonti, Dr. Sergio Scotti
The research focuses on the performances of a traditional single stream MBT for SRF production suitable for co-combustion in a cement kiln. Bio-drying of the residual waste is followed by mechanical refining in order to fulfil the quality requirements by the cement kilns. The residues arising from the mechanical refining section are landfilled in a nearby bioreactor-landfill, where landfill gas is collected for electric energy recovery. A detailed mass balance of the system is presented, followed by a Life Cycle Assessment.
Wasteconsult international Integrated Waste Management System including Waste-to- Biofuels in Western CanadaDr. Christian Felske
The City of Edmonton provides integrated and sustainable waste management Services for residents and for the commercial sector. These services are both economical and mindful of the environment. Up to 60 per cent of residential waste is currently diverted from landfills at the Edmonton Waste Management Centre. This is mainly achieved through recycling and composting processes. Edmonton’s goal is to further raise that diversion rate to 90 per cent. Two projects play a key role in achieving this goal: a High Solids Anaerobic Digestion Facility and the first of its kind Waste to Biofuel and Chemicals Facility. These two projects will be described in more detail in this paper.
Wasteconsult international Landfill mining in practice: Dismantling of the old dump Kössen / AustriaDipl.-Ing. Martin Steiner
This case study presents in its first part a hands-on assessment of the content of a former landfill which was operated between 1920 and 1985 and accepted all municipal waste streams generated in a predominantly rural environment with tourism as a main economic factor. The assessment was performed – according to the principle “let´s replace assumptions by knowledgeâ€ – prior to the complete removal of the landfill Content (volume about 50.000 m3).
The second part gives an overview on the excavation and separation works itself which have been triggered by flood events in summer 2013 (Kössen, a small town located on a river emptying into Chiemsee in Bavaria was the municipality mostly affected by this flood in Western Austria).
Wasteconsult international 3D-Geospatial Data using Unmanned Airborne VehiclesDr.-Ing. Werner Mayr
The use of aerial images for 3D-geospatial information extraction is a known and precise technology. This technology, called photogrammetry, finds application also in Monitoring tasks of landfill sites. One obtains 3D-geospatial information such as volumes, terrain models, profiles, or contours all of which describe the area in a particular way, either for planning or for documentation purposes. Typically, one associates the capturing of aerial images with use of manned aircraft equipped with large format – nowadays digital – aerial camera systems. As aircrafts serve either fixed wing airplanes or Rotary wing aircrafts.

Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Utilization of Treated Solid Waste Combustion Residues in Reconstruction and Vertical Air Space Extension of LandfillsDipl.-Ing. Dr. mont. Renato Sarc, Univ. Prof. Dr.-Ing. Karl E. Lorber, Dipl.-Ing. Dr.mont MScTox Klaus Werner Wruss, Karl Reiselhuber
In this contribution, the utilization of processed MSWI – combustion residues (i.e. bottom ash & slags) for the reconstruction of landfi lls during vertical expansion of airspace is reported. It is shown, that from 250 kg/tonMSW bottom ash generated during combustion, 6 – 7 % FE-metals, 1 – 2 % NON-FE metals and over 90 % minerals (mainly a mixture of CaO, Al2O3, Fe2O3, and Silicates) can be recovered in a processing plant. Using the so called „Concrete Stabilized Perimeter Berm“ method, where parts of the mineral fraction are mixed with cement, sand and water to form concrete for slope construction during the vertical airspace expansion, slope steepening from 1(V): 3 (H) to 2(V) : 3 (H) with simultaneous increase of landfill height from 30 m-45m can be achieved, resulting in airspace gaining.

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.
