Our core business is to challenge the actuel construction market by introducing a new kind of resources : reused building materials. Today, Construction is one of the biggest producer of waste in France, and in the whole world, and it consumes more than 50% of our natural ressources. These are the reasons why we believe that the construction sector will have to face a revolution : introducing circular economy principles into their processes. By allowing actors to buy and sell reused building materials we are convinced that we can advise them and help them build greener buildings. Reused building materials were previously considered as waste and should be considered as ressources. Our B2B plateform is connecting companies that sell second-hand materials with companies who are looking for reused materials to build their construction projects. We created a whole solution from diagnostics to the analysis of the overall gains of a reuse operation, including a quantified financial and environmental report with traceability for each material sold.
