At 7:30 pm on Tuesday, 20 June 2006, an information evening was organised jointly by the community government and EVN Abfallverwertung NÖ at the Zwentendorf Donauhof, to provide the residents of the market town of Zwentendorf with detailed data on the planned extension of the EVN Abfallverwertung NÖ's thermal waste utilisation plant by a third garbage processing line.

Upon welcoming words from the town's mayor, Mr. Hermann Kühtreiber, Ms. Maria Christina Waidmayr, chair of the Citizens Board, introduced the subject. Next followed Mr. Franz Mittermayer, EVN Abfallverwertung NÖ managing director, who presented the concept of the expansion project in its technical details and the application for the environmental impact assessment to be performed for the envisaged third line.

Line 3 is to be modelled along the same well-established technological concept that underlies the existing lines 1 and 2. Like its predecessors it will consist of a grate, boiler and three-stage flue gas cleaning plant (fabric filter, two-stage scrubber and denox plant). The new line will process some 225,000 tons of garbage per year, generating 90 MW in thermal output. Same as the first two lines, it will deliver the energy extracted from the refuse by way of steam to the caloric power station at Dürnrohr where it further adds to the reduction of coal consumption in the generation of electricity, district heating and process steam.

Naturally, EVN Abfallverwertung NÖ is undergoing an environmental impact analysis as required by the law also for its planned third line. On 31 May 2006, it filed its environmental impact statement with the Office of the Lower Austrian Government. Once again, expert opinions on 20 different disciplines running to almost a hundred thousand pages and 5,000 detailed drawings were submitted to the government within the scope of the environmental impact process. Mr. Mittermayer elucidated the process and pointed out the opportunities it offers for citizens to get involved and file comments, before presenting the results of some selected expert opinions on the effect of the new installation on air and climate, noise, traffic, energy and people.

His explanations of the changes to the construction and architecture of the plant were accompanied by a detailed computer-animated show.

The ensuing discussion was dominated by the issue of the traffic infrastructure.
