Project
A new building materials recycling and soil washing plant has been built in Niederstetten near Wil SG. The inauguration and opening of the innovative, flexible and state-of-the-art building materials recycling plant took place on 11 May 2023.
The state-of-the-art process technology sorts, classifies and doses the various material components. ‘In addition, harmful and foreign substances can be efficiently removed, which ensures a significantly improved quality of the products,’ explains Stefan Eberhard, Delegate of the Board of Directors. The building materials produced in this way are of high quality and conform to standards. RCO processes around 200,000 tonnes of construction waste and contaminated excavated material per year. With the recyclable materials recovered from this, over 500 detached houses are built from sustainable building materials every year.
