What Minéka does
Minéka is a French non-profit association (loi 1901) founded in 2016 and headquartered in Villeurbanne, Auvergne-Rhône-Alpes, that operates a matériauthèque — a physical and now digital platform for the recovery, diagnosis, and resale of reclaimed construction materials. Its activities span four integrated lines: Minéstock (solidarity-priced sale of salvaged materials from a Villeurbanne warehouse), on-site collection and material diagnosis services (cumulatively 180,000+ m² diagnosed and 700+ tonnes of materials diverted from waste streams), a bureau d'études / AMO advisory practice that accompanies deconstruction and reuse projects, and Qualiopi-certified professional training delivered to 600+ practitioners since inception.
The operational backbone combines a specialized 7-person team (plus a service civique volunteer and 6 board members) using Odoo for inventory and operations, with deep human expertise in material diagnosis that constitutes the core technical asset. The March 2025 launch of Minék'atalogue extends the warehouse onto a digital sales channel, and Minéka coordinates the seven-member Mat'AURA network of regional matériauthèques while co-founding SPREC, the national professional union for construction reuse.
Revenue is generated through four streams: solidarity-priced material resale, membership fees, project-based AMO/consulting fees from enterprise and public-sector clients, and fees from Qualiopi-certified training programs priced €480–1,000 per session. Minéka has not raised venture funding and operates under a non-profit cost structure typical of French loi 1901 associations, with growth funded organically across revenue lines, public subsidies (ADEME partnership), and volunteer time.

Minéka product offering
Product offeringCore offering
Minéka is a non-profit construction material reuse platform that collects surplus materials from BTP, event, and scenography sites and redistributes them at solidarity prices through a physical warehouse (Minéstock) in Villeurbanne, open to professionals and individuals by annual membership. It complements the material library with an Odoo-based online catalogue, a fee-for-service Bureau d'Études providing PEMD diagnostics and reuse advisory for MOA/MOE, and Qualiopi-certified professional training on reuse methodology.
Product overview
Minéka operates as a multi-service platform for the reuse of construction materials, comprising four interconnected core activities. The Matériauthèque (Minéstock) is the physical warehouse where collected and catalogued materials are redistributed at solidarity prices, accessible via annual membership. The online catalog (Minék'atalogue) extends the stock visibility online for browsing and visit preparation. The Bureau d'études provides specialized reuse advisory and engineering services (PEMD diagnostics, technical reliability, worksite monitoring) to project owners and design teams. The Formation professionnelle (Qualiopi-certified since 2024) delivers training programs for sector professionals, complemented by Sensibilisation programs for students. A free Collecte service for professional BTP members supplies materials into the platform. These services are coordinated from the Villeurbanne headquarters and extend across the AURA region.

Minéka competitors and assessment
Company assessmentBroad incumbents
- Bouygues Bâtiment: Major French construction group and Minéka client (Crédit Agricole campus project via Bouygues Bâtiment Sud-Est). Represents a large incumbent contractor integrating reuse practices — both a customer and a potential ecosystem competitor.
- CSTB (Centre Scientifique et Technique du Bâtiment): French national building science research center that develops standards, certification, and training for the construction sector. Overlaps with Minéka's Qualiopi-certified training and PEMD diagnostic activities at a broader institutional level.
Direct peers
- Backacia: French online platform for resale and exchange of reclaimed construction materials between professionals. Competes in the same reusable BTP materials market as Minéka but with a national digital-only model.
- Bellastock: Paris-based cooperative and matériauthèque focused on construction material reuse, with a bureau d'études offering. Closest direct peer in the French reuse sector and long-standing strategic partner of Minéka.
- La Ferme du Réemploi: French matériauthèque and sister member of the Mat'AURA network alongside Minéka. Operates the same physical warehouse + advisory model in a different region of the AURA territory.
- Reavie: French operator of a matériauthèque and reuse services platform, comparable in mission and offering to Minéka. Targets similar professional and individual buyers of salvaged construction materials.
- Rotor DC: Belgian cooperative specializing in dismantling and reuse of construction materials, with a matériauthèque and advisory services. Closest international peer in the European reuse sector with a similar non-profit/ESS structure.
- ÉCO'MAT 38: French matériauthèque and member of the Mat'AURA network alongside Minéka. Operates a comparable physical warehouse + selective deconstruction service model in the Isère department.
- Cycle Up: French national digital platform connecting material suppliers and buyers in the construction reuse ecosystem. Operates a complementary online marketplace model to Minéka's physical matériauthèque, serving overlapping MOA/MOE audiences.
Emerging players
- Materrio: French initiative coordinated by the building sector to develop construction material reuse. Adjacent to Minéka's mission, focused more on sector coordination and standards-setting than direct warehouse operations.
