Relevant Emissions During Landfill Mining Processes© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Because of landfill mining activities emissions will occur. They can cause considerable effects to the environment and the vicinity. The most important emission may be the odour, but also dust and noise can be relevant to the neighborhood.
Biological Stabilization of the Teuftal Landfill in Switzerland© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
The Teuftal landfill, located in the canton Bern, is considered the largest sanitary landfi ll in Switzerland. Since 40 years both, municipal solid waste (MSW), construction and demolition waste, bottom ashes, flue gas cleaning residues as well as industrial waste are disposed of in different landfill sections. Untreated MSW of relatively high organic content has been landfilled in particular between 1973 and 2000 on an area of approximately 12 hectare, subdivided into 3 sectors.
An Extensive Environmental Protection Program During the Bonfol Landfill Remediation© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
The industrial waste landfill at Bonfol in the Canton of Jura, Switzerland, is a heritage of our past. The chemical industry of Basle, amongst others, dumped its production waste in a former clay pit during 15 years before the landfi ll was closed in 1976 with a clay cap. Today, the organizational and technical challenge consists in excavating nearly 175,000 tons of hazardous waste material under high safety and environmental protection measures.
MBT-Landfill as Carbon Sink – Expected Carbon Content after Aeration© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Target of MBT (mechanical biological treatment of wastes) is to mineralise and to stabilise waste organic matter. This leads to a reduction of emissions after landfi lling the pretreated wastes. It is well known, that MBT-landfills can be seen as a carbon sink, but there is a deficit in knowledge about the time frame respectively which share of organic carbon will remain in the landfill over long period.
Former Tannery Waste Disposal Site – Excavation of Intense Odour Waste© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
The contaminated site ST19 (Gerbereideponie Schmidt), a former tannery waste disposal site, is situated in the southern part of the city of Weiz (Styria, Austria). The area is split up into two parts by a main road passing the landfill.
In-situ Aeration: Performance Control after 5 Years on a Municipal Solid Waste Landfill© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
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.
Aeration of the Landfill Pill; Effects on Groundwater Contamination© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
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.
Deformation Analysis of the Landfill “Rautenweg“ using 3D-Finite Element Modelling© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
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.
Verification and Control of Geotextiles According to DVO and Ă–N S 2082© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
The Austrian landfill regulation DVO 2008 and its attachments generally admit to use geosynthetics as an alternative to mineral components used as sealing or drainage elements. The requirements needed to proof equivalency are described for each landfi ll class separately. Paragraph 5 and 6 and attachment 3 of the DVO defi ne the appropriate minimum requirements or limit values respectively.
Water Balance of Layered Mineral Landfill Cover© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
According to the presented monitoring system, the functionality of the individual components of the temporary surface cover system in Rastorf (Schleswig-Holstein) can be permanently monitored and evaluated under in-situ conditions.
