Hébert Group and ANDRITZ Shift the Dry Molded Fiber Paradigm

The End of the Wet Era: Hébert and ANDRITZ Shift the Paradigm

For decades, those of us who have spent a lifetime in the packaging industry have known that the Achilles' heel of traditional molded pulp was its insatiable thirst for water and energy. As environmental regulations tighten globally, the industry has been desperately searching for a process that bypasses the drying bottleneck. Today, the landscape is shifting dramatically. The recent confirmation that France-based Hébert Group is aggressively scaling its Dry Molded Fiber (DMF) production alongside technology giant ANDRITZ is not just another corporate PR move; it is a clear signal of industrial maturity for a technology poised to rewrite the European and global market rules.

Located in Orgelet, France, the family-owned Hébert Group is no stranger to high-performance packaging for major food, dairy, and cosmetics brands. However, its strategic decision to carve out a dedicated business unit, Herpulp, demonstrates that the pivot from single-use plastics to fiber is no longer a marketing pilot—it is a long-term commercial reality. The timing is impeccable, right in the thick of the 2024-2025 push where FMCG companies are scrambling to meet looming plastic reduction targets.

Technological Convergence: Airlaid Meets Thermoforming

Dry Molded Fiber, originally driven by PulPac's innovative licensing model, shapes natural cellulose using a mere fraction of the water and energy demanded by wet molding. What makes the ANDRITZ partnership a critical turning point is the seamless integration of battle-tested industrial technologies. We are looking at a sophisticated process that merges airlaid forming (leveraging ANDRITZ's Dan-Web mill-to-web technology), nonwoven converting, and high-speed thermoforming into a continuous operation.

Julien Hébert, the group's CCO, has made the market's mandate clear: top-tier brands demand genuine, fossil-free sustainability without sacrificing line speeds or the precise geometries required for modern trays and lids. Following a rigorous period of parameter optimization, technical visits, and process upgrades throughout 2024 and 2025, their first-generation Modula lines are proving that profitable commercial volumes are attainable. Furthermore, the backing of ANDRITZ's technical center in Grenoble's "Cellulose Valley" provides the crucial safety net needed to de-risk these operations, allowing for robust material formulation and mold validation before full-scale commercial runs.

Market Impact: Economics and the Supply Chain

What does this mean for the wider industry? The implications ripple across the entire supply chain. For pulp producers, DMF opens a premium demand channel that easily justifies new mill investments—a sentiment echoed by Bruno Roche, Senior VP at ANDRITZ Nonwoven & Textile. He correctly notes that converting even a fraction of the single-use plastic market to fiber represents a massive capital opportunity.

For converters and machinery builders, it establishes a fierce new baseline for competitiveness. Cost-effective DMF production relies heavily on suitable, low-cost raw materials paired with automotive-level expertise in pressing and molding. If Hébert Group succeeds in its next ambition—stabilizing deep-draw product manufacturing and co-developing tailored, lower-cost molds—the barrier to entry for DMF will drop significantly. This will apply immense pressure on traditional rigid plastic players who have so far relied on the argument that fiber cannot match plastic's formability or unit cost.

The learning curve for stabilizing these advanced lines is undeniably steep. Yet, ANDRITZ's "Solution as a Service" model, supporting clients from confidential pilot testing to turnkey facilities, could dramatically accelerate global DMF adoption. We are witnessing the birth of a supply chain that finally marries the manufacturing flexibility and speed of plastics with the intrinsic circularity of paper.

It is genuinely refreshing to see legacy converters deploying real capital to solve the energy puzzle of fiber molding, proving that smart engineering can make sustainability profitable at an industrial scale. Will smaller packaging converters be able to shoulder these technological transition costs before well-backed pioneers like Hébert lock down all the major brand contracts?
