Concular - Digital platform enabling circular construction

Updated on 24.06.2024

This tool aims to 'transform the real estate and construction industry towards a circular, sustainable way of doing business' through an AI-driven platform that matches buyers’ demand for construction material with suppliers’ circular materials. Material demands from construction projects can be uploaded onto the platform, while circular materials from demolition projects can be recorded using a digital material passport. Note: This platform is active in Germany and it is in German, but is easy to navigate with the page translation function of most search engines.

Relevance for Circular Systemic Solutions

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'.

How to use this tool or method

The platform functions like an online secondhand market where interested parties can buy or sell secondhand construction materials and machinery. Users are able to filter based on categories of products such as windows/glass, lamps, ors/frames, flooring/ceilings, facades etc.
