The futuristic Greencity district is currently under construction on the former Sihl-Manegg industrial site in Zurich South. Covering an area of around eight hectares, a diverse site defined by its focus on sustainability is emerging.
Entry from 05.08.2025
KIBECO supplied 11,800 m³ of concrete fumigated with CO₂ for the current construction phases. Ten kilograms of CO₂ per cubic metre are permanently stored in the KIBECO concrete. For a quantity of 11,800 m³ of concrete, this corresponds to a stored quantity of 118 tonnes of CO₂. This CO₂ has been permanently removed from the atmosphere and stored in the recycled building material. By way of comparison: around 9,440 mature beech trees would be needed to store the same amount of CO₂.
