What Cavac Biomaterials does

Cavac Biomaterials (Cavac Biomatériaux) is a Vendée-based French industrial manufacturer and wholly-owned subsidiary of the Cavac agricultural cooperative group, founded in 2009 to industrialize the transformation of plant fibers—primarily hemp and flax grown by cooperative members within a 100 km radius. The company operates a 2,500 m² integrated production facility (with 10,000 m² of storage) featuring three automated production lines: defibring, multi-component nappling (blending up to four components for nonwoven mats), and micronization of lin anas and chènevotte. This combination is described as unique in Europe and enables complete, zero-waste valorization of hemp and flax into fibers, chènevotte (shives), and fines, each routed to specific industrial applications.

The company's commercial portfolio spans three branded product lines and four raw-material streams. Biofib'Isolation is the flagship consumer-facing brand selling ACERMI-certified hemp-based thermal insulation in bulk, rigid, and semi-rigid formats; Biofib'Jardin supplies hemp-shive garden mulch; and Zen'lit provides hemp-shive animal bedding. At the industrial B2B level, the company supplies nonwoven hemp-fiber mats, chènevotte, fines, and micronized vegetable matter for integration into PVC, PP, and PE polymer matrices used in automotive door panels, cockpit components, soundproofing elements, bioplastic composites, and construction products such as hemp-lime renders and dry screed.

The business model is hardware-sales driven, with distribution executed through two channels: (i) building material merchants (négoce) across France for branded insulation products targeting SMB construction professionals and artisans, and (ii) direct enterprise sales to automotive, bioplastics, and agro-composite manufacturers for technical fibers and micronized materials. Pricing is quote-based and not publicly disclosed. The company generated a major capacity expansion in September 2024 with a €20M+ farmer-invested Biofib Isolation plant opening in Sainte-Hermine, and holds ISO 9001:2015 certification (issued by SOCOTEC) covering processing of plant-origin materials and production of biomaterials, biomass, and agro-composites.

Core offering

Cavac Biomatériaux industrially transforms hemp and flax plant fibers into biosourced materials for construction, automotive, bioplastics, gardening, and animal care applications. Its core output is the Biofib'Isolation range of hemp-based thermal insulation products (bulk, rigid, and semi-rigid formats with ACERMI certification), alongside raw plant materials (fibers, chènevotte, fines, micronized matter) supplied to industrial manufacturers. The production model emphasizes full plant valorization with zero waste, leveraging a vertically integrated supply chain through the parent Cavac cooperative.

Product overview

Cavac Biomatériaux operates as a manufacturer of bio-sourced materials derived from plant fibers (hemp and flax), organized as a subsidiary of the Cavac agricultural cooperative group in Vendée, France. The product portfolio centers on the Biofib'Isolation brand of hemp-based insulation materials (bulk, rigid, and semi-rigid formats with ACERMI-certified thermal performance), supplemented by two consumer sub-brands—Biofib'Jardin (garden mulch) and Zen'lit (animal bedding)—that leverage chènevotte (hemp shives) from the same processing stream. Beyond branded products, the company supplies a range of raw industrial materials including hemp fibers (bulk/non-woven mats), chènevotte, fines/dust from defibration, and micronized vegetable matter for agro-composite applications. The integrated industrial facility in Vendée is unique in Europe, processing the entire hemp plant from straw to dust with zero waste.
