MAS Réemploi (ex-MRBC)

What MAS Réemploi (ex-MRBC) does

MAS Réemploi (formerly MRBC, Montpellier Rebuilding Center) is a French nonprofit association (Association loi 1901, SIRET 853 572 519 00025) operating a construction-material reuse platform in the Montpellier metropolitan area. The association was legally constituted on 1 July 2019, rebranded to MAS Réemploi in 2024, and is led by President Thomas Nougaret. It runs a 5,000 m² physical platform across two sites — a warehouse at 46 chemin des Mazes, Le Crès, and a showroom at 56 avenue du Marché Gare, Montpellier (opened 2024) — complemented by an Odoo-based e-commerce shop with 25+ product categories spanning masonry, carpentry, roofing, finishes, flooring, plumbing, electrical, HVAC, hardware, and furniture.

The organization collects, conditions, certifies, and resells reclaimed building materials sourced from demolition, déconstruction, and rehabilitation sites, as well as voluntary contributions from professionals and individuals. Core operational tooling includes 'La Dimensionneuse', an internal system that produces standardized product sheets on material entry, and a rigorous traceability framework that records origin, applicable French/EU norms, provenance, nature, and transformations, with each item accompanied by a certificate of origin. A future BIM library of reusable building elements is on the product roadmap. Beyond material resale, MAS Réemploi delivers professional services: PEMD/resource diagnostics, Assistance à la Maîtrise d'Ouvrage (AMO), selective dépose préservante, and training/awareness programs for the public and BTP professionals. Following the 2024 merger with Cycles & Sources, it has also integrated raw-earth consulting and training into a dedicated study-office pole.

MAS Réemploi monetizes through three streams: unit-priced sale of reclaimed materials (HT pricing, 20% VAT, customer pickup only), fee-based professional services, and memberships/donations (including merchandise and €1-€10 donation tiers). It serves three horizontal segments — particuliers for home renovation, professionnels (artisans, architects, BTP firms) for construction supply and diagnostics, and collectivités (local authorities, with named clients including Ville de Montpellier, CNFPT, and Agence de l'eau). Distribution is regional (Occitanie) and combines direct physical sales, an online shop, and a partner referral network that includes CRESS Occitanie, CMA Occitanie, CAPEB Hérault, CCI Hérault, Envirobat Occitanie, Altéméd, and Région Occitanie. Documented impact includes 15+ tonnes of materials saved and 23 tonnes eq.CO² avoided on the Montpellier parquet project, and 7.5 tonnes rescued from the FISE 2022 festival.

Regional players

• Build Reuse: US-based non-profit association promoting building materials reuse through its directory of reuse centers. Conceptually analogous organization/association model, though operating in a different geography.

Broad incumbents

• Back Market: Large-scale recommerce marketplace applying a reuse/resale model to refurbished goods. Relevant as a broader incumbent demonstrating the scale potential of structured recommerce platforms, though in electronics rather than construction.
• Emmaüs Ressourceries: Established French social/reuse network operating ressourceries that divert goods (including some building materials) from waste. Overlaps with MAS Réemploi on the social-insertion and reuse mission but covers much broader categories.
• Le Relais (Emmaüs): French social enterprise focused on textile reuse and recycling with broader solid-waste and reuse activities. Comparable as a social-economy operator with circular materials flows and public-policy alignment.

Direct peers

• Mobius: French reused-materials marketplace connecting demolition sites with buyers, with material traceability features. Closely aligned with MAS Réemploi's resale and provenance-tracking model.
• Réavie: French social-economy enterprise reselling reclaimed building materials, often operating as a réseau national. Comparable in mission (social insertion + circular construction) and resale activity.
• Les Docks du Réemploi: French reused-building-materials platform with showrooms and online catalog. Comparable in offering a physical + digital marketplace for reclaimed construction components.
• Cycle Up: French platform and services company focused on reused building materials, including diagnostics, marketplace, and circular construction advisory. Most direct functional peer to MAS Réemploi across the Occitanie/Ile-de-France landscape.

Others

• Envirobat Occitanie: Local chapter of New European Bauhaus in Occitanie, an ecosystem partner of MAS Réemploi that organizes platform visits and circular-construction awareness. Adjacent enabler in the same regional value chain rather than a competitor.
• CRESS Occitanie: Regional Chamber of the Social and Solidarity Economy, partnered with MAS Réemploi for professional visits and networking. Ecosystem enabler for SSE/circular-economy actors in the same region.
