The project aimed to overcome preconceived notions against the use of recycled concrete in building construction and stimulate demand for recycled concrete as a circular input in the construction market. Results from an earlier pilot project also confirmed that early announcements and communication can be useful. As a result of the success of the pilot and subsequent uses, the City of Berlin requires recycled concrete to be used in all public high-rise construction projects. This is expected to replace approximately 100,000m3 of standard concrete annually.
