This tool provides a platform for cities and regions that are interested in deploying circular systemic solutions in the built environment sector. The platform can help public authorities, as well as businesses in waste management, with the Mapping and Designing stages of CSS deployment. Specifically, the tool can be useful for 'Analysing the metabolism of the territory' and 'Engaging key stakeholders' as it also serves as a digital hub where reuse professionals can network, promote their skills and grow their business.

The platform functions like an online secondhand market where interested parties can buy, sell or share secondhand construction materials, furniture, machinery, and ideas. Users are able to narrow down their search results based on categories such as 'ideas, resources, professionals' and classes of products in Italy. While registration is necessary to use the platform fully, it can be done for free.
