Excursion to waste disposal plants
On September 20, 2017 there will be an excursion to selected waste disposal plants in and around Vienna. Delegates of the IRRC Waste-to-Energy have the possibility to participate in that excursion. Since the number of available places is limited, it is advisable to register before September 6, 2017.
Registered participants will be picked-up and returned in front of the congress venue Vienna Marriott Hotel. The groups will get a guided tour at each site in English. Each group will have a size of max. 15 people.
Pfaffenau waste incineration plant
Since autumn 2008, the Pfaffenau waste incineration plant (German acronym “MVA”) has been producing approx. 410 GWh (gigawatt hours) of district heat and 65 GWh of electricity from approx. 250,000 tonnes of residual waste annually, thereby supplying approx. 50,000 Viennese households with district heating and approx. 25,000, with electricity. A four-stage flue gas scrubbing plant decreases emissions to a minimum.
The biogas plant went into operation in 2007 and is run by the Vienna Municipal Department for Waste Management, Street Cleaning and Vehicle Fleet (MA 48). The facility processes about 22,000 tons of kitchen waste every year – mainly the contents of organic waste containers in Vienna’s inner-city districts, as well as leftover food from restaurants, canteens and industrial kitchens, market waste and expired food. The moisture content of these materials is high enough to allow for fermentation.
Simmering waste logistics centre (German acronym “ALZ”)
It is the most recent element of the comprehensive waste disposal system of Vienna is provided by the new Pfaffenau waste logistics centre in the 11th municipal district Simmering. This high-tech installation adjacent to the Pfaffenau waste incineration plant serves for the processing and interim storage of residual and bulky waste. If necessary, the pre-treated, compacted waste is wrapped in airtight bales and stored until incineration without releasing unpleasant odours. This ensures reliable disposal even in case of repairs or downtimes at waste incineration plants. The facility ensures that all waste collected can be properly disposed of, irrespective of the waste volume or capacity utilisation of Vienna’s waste incineration plants.
The Rinter Tent (or “MA 48 Tent”) is the central hub of separate recyclable collection. This is where the various fractions are re-sorted, stored on an interim basis and then sent on by rail for further processing. Problematic waste is likewise sorted and stored here temporarily at a special collection point before recycling or final disposal. Waste incineration residues (ash and slag) are demetallised and converted into slag-ash concrete. Rautenweg landfill This concrete is then properly disposed of at the Rautenweg landfill. The local groundwater stratum is protected by a retaining wall ("Vienna sealed-wall chamber system"). Moreover, the landfill boasts a unit for landfill gas capturing and utilization, which generates electricity for approximately 2.200 households, and operates several technical and organizational safety installations.
