Vienna plans new waste treatment plant in Donaustadt — €240 million project by 2034 Vienna plans new waste treatment plant in Donaustadt at Rautenweg landfill: €240m reserved until 2034, construction from 2030, operation in 2034 and circular economy tech. Topics: News, Politics, Economy.

Vienna is launching a major infrastructure project for the coming decades. The city plans a new waste treatment plant in Donaustadt right next to the existing Rautenweg landfill. The facility is scheduled to enter operation in 2034, with construction starting in 2030 at the earliest. In this guide you will learn where it will be built, why Rautenweg was chosen, how much it costs, how demographics and waste volumes are linked, and what will happen to the existing plants Flötzersteig and Spittelau.

What is known about the new waste treatment plant Vienna Donaustadt

The City of Vienna has started planning a new Abfallbehandlungsanlage — a modern treatment plant for residual and bulky waste. As MeinBezirk reports, the municipal department MA 48 submitted the proposal to the city’s environmental committee (Umweltausschuss). The project is not a landfill extension but a full treatment facility that will process Restmüll (residual waste) and Sperrmüll (bulky waste), recover recyclables and generate energy.

According to wien.ORF.at, the main driver is population growth. Vienna expects around 2.4 million residents by 2055, with the strongest increase north of the Danube — Floridsdorf +19% and Donaustadt +39%. The new plant is meant to secure Entsorgungssicherheit (disposal security) for the long term. As Vienna.at notes, the project is already anchored in the current government programme of the City of Vienna.

For context: Vienna’s entire waste chain — from collection to thermal treatment and the disposal of residues — is in municipal hands via MA 48. As wien.gv.at explains, this structure guarantees disposal security at a high environmental standard.

Location Rautenweg in Donaustadt — why there

The new plant is planned directly beside the existing Reststoffdeponie Rautenweg in the 22nd district (Donaustadt). According to Vienna.at, the areas at Rautenweg are already zoned for this purpose and partly owned by the city, which shortens procedures and reduces land-use conflicts.

Rautenweg is Austria’s largest landfill at about 60 hectares with an approved volume of 23.31 million cubic metres, operating since 1961 on a former gravel pit. Today it only stores treated, odourless residues from Vienna’s incineration plants — up to 200,000 tonnes of slag and ash per year after metal recovery at the Rinter site. Locating the new plant next to an established hub leverages existing infrastructure and access roads.

The choice of Vienna’s northeast is also demographic: this is where household growth and Siedlungsabfälle (municipal waste) will rise fastest. If you are exploring renting in Vienna and Austria or new developments beyond the Danube, waste logistics directly affects liveability — from collection routes to air quality. The summer pressure on city services is visible every year, as we describe in Vienna construction sites in summer.

Costs, budget and timeline until 2034

The financial framework is already outlined, even though the final price tag is still open. An initial €13.7 million is earmarked for expert reports (Gutachten) and investigations, as reported by MeinBezirk. From the ongoing budget, €240 million is to be reserved by 2034.

As Heute.at underlines, the ultimate total cost has not been fixed — the project is still at an early stage. The next steps build on a two-year Strategic Environmental Assessment (SUP) carried out with city officials and environmental experts.

Timeline: construction start 2030 at the earliest, commissioning 2034. This schedule is timed to the planned refurbishment of the Flötzersteig and Spittelau plants from 2035. For background on how Vienna funds such projects, see our analysis of the budget crisis and municipalities.

Technology and environmental standards

The new facility is conceived as a building block of the circular economy (Kreislaufwirtschaft), not just another incinerator. According to wien.ORF.at, it will combine material recovery (Wertstoffrückgewinnung) with energy recovery: recyclables are recovered, the remainder is thermally treated and the waste heat is converted into electricity and district heating for households, especially north of the Danube.

Planned features include photovoltaic systems, green façades and roofs and an electric vehicle fleet with charging stations. This aligns with Vienna’s goal of climate neutrality by 2040. The EU Waste Framework Directive sets the benchmark: by 2035 at least 65% of municipal waste must be recycled or reused.

A side note concerns textiles. As MeinBezirk reports, the Greens see the new plant as an opportunity to reorganise textile collection. From 2027, clothing containers in public space will be banned due to littering; the city, together with social enterprises, is expected to rebuild collection, sorting and reuse via MA 48.

With the new facility we want to ensure disposal security for the future while combining circular economy and energy generation.

Why population growth in Donaustadt and Floridsdorf matters

More residents mean more residual and bulky waste — a direct driver for additional treatment capacity. The forecast of 2.4 million by 2055 and the disproportionate growth in the north explain both location and scale. The plant is placed where demand will grow fastest.

For newcomers and house-hunters this signals urban development: new quarters need robust utilities. If you compare prices and availability, our overview of housing in Austria: prices, rent and inflation provides context. As Vienna.at notes, Vienna intends to continue treating municipal waste within city limits with its own capacities.

What happens to Flötzersteig and Spittelau and how politics reacts

The timeline of the new plant is tightly linked to the refurbishment of Flötzersteig and Spittelau from 2035, as Heute.at reports. During those works the Donaustadt facility will prevent bottlenecks and keep supply — especially for residual and bulky waste — stable.

First political reactions came from the Greens. They welcome the new build but tie it to a demand to rethink the Altkleider system: from the 2027 ban on public containers to expanding collection and recycling through MA 48 and social enterprises. For local residents little changes in the short term — construction starts only in 2030 — but the course for the next two decades is being set now.

Frequently Asked Questions

When will construction start and when will the plant open? Construction is scheduled to start in 2030 at the earliest, with commissioning in 2034 — in time before the refurbishment of Flötzersteig and Spittelau from 2035.

Where exactly will the new plant be built? Directly beside the existing Reststoffdeponie Rautenweg in Donaustadt (22nd district). The areas are already zoned and partly owned by the city.

How much will the project cost? €13.7 million is budgeted for planning and expert reports. €240 million will be reserved from the ongoing budget until 2034. The final total is not yet fixed.

What will the new plant do differently? It will treat residual and bulky waste, recover recyclables and generate energy (electricity and heat). Planned features include photovoltaics, greening and an e-fleet.

What it means for residents — and what to do next

Vienna is planning ahead: 2.4 million residents by 2055, 65% recycling by 2035 and climate neutrality by 2040 set the frame. The new waste treatment plant in Donaustadt creates capacity where the city grows fastest and just before existing plants go into refurbishment.

Checklist if this topic affects you:

• Live in Donaustadt/Floridsdorf or planning a move — follow the SUP results and MA 48 planning updates and note participation dates.
• Sort waste consistently at home — the 65% quota affects every household.
• House-hunting in the north — consider infrastructure development alongside rent and transport — disposal, traffic and energy go together.

In the long run the new Abfallbehandlungsanlage Wien Donaustadt secures Vienna’s disposal from its own resources — with circular economy, energy and reserves for the refurbishment of existing plants. Stay informed and subscribe to our newsletter so you don’t miss Vienna updates.
