In France, the construction sector accounts for about 70% of the waste produced, yet less than 1% of materials from construction sites are reused. However, many of these materials are still in very good condition. "We throw them away because no one has yet created the link between those who have the materials and those who need them", explains Karima Lebsir. For her, the issue is primarily about organization and the circulation of materials.
With Cycle Zéro, companies can donate their materials for free, which individuals can then pick up directly from the construction sites. This solution helps avoid disposal costs and provides access to materials at lower prices. Last year, 30,000 materials were reused, benefiting over 25,000 families. "That’s over a million euros redistributed", emphasizes the co-founder.
Beyond the environmental impact, the project advocates for a social vision of ecological transition. Renovating one’s home or equipping it can be expensive, and reuse makes these options more accessible. "We clearly make the connection between environmental transition, ecology, and purchasing power, social justice", insists Karima Lebsir. The app currently has over 300,000 users across France, although some companies remain reluctant to change their habits.
To accelerate the movement, the co-founder calls for stronger commitment from public authorities and businesses. Indeed, despite existing solutions, waste remains deeply ingrained in the sector's practices. "I hope that in 20 years, it will no longer be waste at all. It will already be reused, used directly", concludes Karima Lebsir.
