SIAS & Enercoop Syrdall

Biology Center – “Naturzenter SIAS” (

It is the Biological Center-Naturzenter SIAS who is responsible for tasks concerning the protection of nature and environments.

Since 1989 the municipal syndicate SIAS (Niederanven, Schuttrange, Sandweiler, Contern and Weiler-la-Tour) is active in the implementation of projects in the field of nature and environment protection. In 2000, the SIAS Naturzenter took over the coordination of tasks related to the protection of nature and up from 2003, on the initiative of the Ministry for environment, the biology center supports the protection of the natural communal territory. Beside the organization and coordination of planting works and maintenance tasks, the Naturzenter SIAS is primarily an assistance for any questions or problems concerning the protection of nature and environment.
In practice, the protection of nature encompasses planting and cutting of fruit trees, hedges, native shrubs, solitary trees and willows. Water bodies are arranged and promoted environmentally. Programs for the protection and maintenance of nature and landscapes are developed, biodiversity contracts are made with farmers - by which, in case of mutual agreement, the variety of species is favored. Related programs for the protection of endangered animals such as for example the little owl or bats are set up. A certain awareness concerning the protection of nature among the inhabitants is being considered.

In March 2019, 16 founding members, resident of the municipalities of Niederanven, Contern, Sandweiler and Schuttrange, founded the inter-municipal energy cooperative “EnerCoop Syrdall”.

The aims of this cooperative are among others :

  • implement and develop projects for the production, purchase, distribution and sale of renewable energy;
  • to promote a rational and responsible use of energy among its members and the general public, and
  • promote and contribute to the energy transition and combat energy poverty.

The first 4 initial projects in the field of photovoltaics were carried out - in close cooperation with the leaders of the 4 municipalities during the years 2019 and 2020 and financed by the 138 cooperants. In our municipality, the connection of the photovoltaic installation on the roof of the school "am Sand" to the CREOS network was finalized on December 9, 2019. Indeed, these are installations with a combined power of more than 250 kW. Other projects will follow in the following years.
