Circular Economy: Gérim and Carrières du Boulonnais work together to build a Decathlon warehouse made of recycled concrete
Gérim has built a warehouse made of recycled concrete in partnership with Carrières du Boulonnais (CB Group).
The Decathlon warehouse in Lompret (59) is a real example of the application of the circular economy concept to a building-site as part of a low-carbon project that saved natural resources and thus avoided the extraction of aggregates from quarries. The alternative aggregates used in one area were reused locally (in this case, crystallised aggregates from blast furnaces). The successful implementation of the project was notably due to the involvement of three regional players committed to various circular economy approaches and who decided to pool their strengths and skills, namely: the Gérim company, the Rabot Dutilleul Group’s general contractor and owner of the project, which wished to innovate as part of one of its contracts; the CB Group, a manufacturer/producer of concrete, which was able to provide an alternative solution for the same price and to the same standards; and, finally, the Neo-Eco Recycling company, which was in charge of monitoring the environmental impact and of measuring the ecotoxicity effects on fauna and flora.
This first project resulted in new partnerships. Regular implementation of this type of partnership will help sustain this sector, create local jobs in high quality recycling and avoid the need to ship materials over long distances by recycling them locally. The impact on carbon reduction will also be positive.
