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. The group size is limited to max. 25 people.

Spittelau Waste Incineration Plant designed by Hundertwasser 

The waste incineration plant Spittelau was constructed from 1969 till 1971. A few years later, in 1987, a large re destroyed most of the facility. Instead of tearing down the plant, Helmut Zilk – the mayor at the time – decided to rebuilt it in accordance with the highest standards regarding the technology and the environment protection. But even that was not enough. In addition to the technological improve- ments, it became an artwork. The environmentalist, nature lover and artist Friedensreich Hunderwasser created the unique design, for which it is world- famous today. From 2012 to 2015, after an operation time of more than 40 years, the waste incineration plant Spittelau had to undergo a complete refurbishment. Today, it incinerates around 250.000 tonnes of houshold waste per year. With an installed overall performance of 400 MW, an average production rate of 120 GWh of electricity as well as 500 GWh of heat, this plant is the second biggest generation site in the district heating system of Wien Energie. An it provides annually more than 60.000 households with its eco-friendly heat.

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.

Biogas plant

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.

Rinter Tent

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.
