New energy centre for the Limmat Valley

Dietikon ZH/Zürich , January 2025

A team led by Zurich architects Penzel Valier AG will be responsible for the overall concept of Limeco's Limmat Valley Energy Centre. The team's consideration of the environment, economy and society was convincing.

A team led by the architectural firm Penzel Valier AG from Zurich has won the study contract for Limeco ‘s Limmattal EnergyCentre (LEZ), as detailed in a press release. The project, which Limeco describes as a generational project, includes the construction of a new waste incineration plant and the expansion of the wastewater treatment plant in Dietikon. Limeco will produce CO2-neutral energy for the Limmat Valley from waste and water.

According to Limeco, the aim of the study contract was to develop an overall concept in which the LEZ blends into its surroundings and the various requirements of the neighbouring areas are taken into account. At the same time, the project should be easy to expand and remodel.

The winning project “successfully mediates between the Silbern industrial estate and the floodplain landscape”, Stefano Kunz, Chairman of the Board of Directors of Limeco and chairman of the assessment panel, is quoted as saying in the press release. It “coherently and stringently combines the social, local and operational requirements” and thus creates great added value.

The waste incineration plant will reach the end of its service life by 2034 and therefore needs to be rebuilt. The WWTP is to be expanded by 2050. According to Limeco, it is committed to engaging in dialogue with its sponsoring municipalities, the local population, the canton and nature and environmental protection organisations when planning the project. The results of the participatory process launched in 2020 are documented in two white papers. It was used as the basis for the study contract.

The project designs of the six teams that competed for the study contract will be made available to the public on 18 and 19 January and 1 February at Heimstrasse 46, 8953 Dietikon.
