The CityLoops project was a Horizon 2020 project which ran from 2019 to 2023. It focused on circular economy solutions for bio-waste and construction and demolition waste (CDW).

The project developed several instruments addressing circular construction and demolition projects which were used by the project cities in their demonstration actions. As part of the legacy of the project, the Replication Packages are meant to make these experiences from demonstration actions and instruments in CityLoops available for other cities in Europe to use and replicate. They address specific actions within circular construction, for instance guiding cities in choosing a method for registering data and creating a material passport, helping them in the creation of a flow for recycling concrete, or giving them instruments for evaluating the possibilities of reusing soil on-site.
