Sustainable materials in action: how the industry is implementing bio-based solutions on a large scale

From the castor bean supply chain to advanced 3D printing, here is how the industry is turning the promises of sustainable materials into concrete actions.

The industrial implementation of bio-based materials is no longer a future promise, but an operational reality that is redefining production processes in key sectors such as automotive, aerospace, and advanced manufacturing. Through structured programs that integrate responsible agriculture, European research, and circular economy platforms, companies are demonstrating that sustainability and technical performance can coexist on an industrial scale.

The sustainable supply chain from origin: the Pragati case

A vertical integration model that links responsible agriculture to the production of high-end bio-based materials.

The Pragati program represents a concrete example of how material sustainability begins long before the production phase. This initiative focuses on the sustainable cultivation of the castor bean, the plant from which the oil is extracted to produce the Rilsan® Polyamide 11 family of polymers, advanced materials derived from renewable feedstock.

The program goes beyond simple bio-based certification: it works directly with local castor bean farmers to improve agricultural practices and ensure sustainable living conditions. This vertical integration approach demonstrates that high-performance materials can be produced starting from a responsible agricultural supply chain, creating both environmental and social value. The resulting Rilsan PA11 polymers are used in advanced industrial applications, including 3D printing, where their mechanical properties and renewable origin represent a concrete competitive advantage.

Bio.3DGREEN: European innovation for advanced polymers

How European research is accelerating the introduction of biopolymers into the high-tech manufacturing sector through a multidisciplinary consortium.

Launched in May 2025, the European project Bio.3DGREEN brings together 14 partners from nine countries across Europe and the United Kingdom, coordinated by the Laser Zentrum Hannover. The consortium integrates expertise ranging from materials science to laser engineering, from artificial intelligence to industrial standardization, with partners such as the FIAT Research Center, Tenneco Automotive Europe, and DIN (the German Institute for Standardization).

The project, funded by Horizon Europe until October 2028, aims to develop graphene-based components produced from vegetable oil, with a process designed to be carbon-positive. The goal is to replace fossil materials used for NVH (Noise, Vibration and Harshness) applications in the automotive, aerospace and naval sectors with biomimetic porous structures that mimic natural architectures such as human bone or marine sponges.

The presence of industrial players such as FIAT and Tenneco signals the direct interest of the automotive sector in this technology, while the involvement of DIN ensures that new materials are accompanied by shared industrial standards, a crucial element for large-scale adoption.

Meanwhile, other research projects are exploring the use of polyhydroxybutyrate (PHB) combined with lignocellulosic biocarbon for selective laser sintering (SLS). These PHB-biocarbon composites, fully renewable, are being studied as a sustainable alternative to traditional fossil polyamides for non-structural applications where the priority is to reduce environmental impact.

Closing the loop: the role of Virtucycle in industrial recycling

Digital platforms that enable the recovery and reuse of high-performance materials in a circular perspective, connecting suppliers and users.

Arkema's Virtucycle® program represents an operational circular economy model applied to high-performance polymers. This partnership program is offered to customers who use polyamide 11, polyamide 12, PEBA elastomers and PVDF fluoropolymers, acting as an intermediary between those who want to recycle their polymers and those who wish to purchase partially recycled grades with a more favorable LCA profile.

The program collects injection or extrusion scrap, powders, parts and granules of long-chain polyamides, both pre-consumer (industrially processed materials but not transformed into finished products) and post-consumer (materials already used in final applications). The acquisition of Agiplast, a recycler specialized in high-performance polymers with experience in re-engineering and re-compounding, has added a new dimension to the traditional offering.

Arkema provides recycled polymer grades certified by independent bodies such as SCS Global Services, which in June 2024 recertified over 26 references for recycled content. The company guarantees that recycled materials contain a minimum certified content of recovered material and maintain properties similar to virgin materials, a fundamental element for industrial applications where performance cannot be compromised.

This "match-making" model between waste suppliers and recycled material users demonstrates how circularity can be integrated into complex industrial supply chains, maintaining the quality standards required by demanding sectors.

Conclusion

The industrial implementation of sustainable materials is no longer just theory: it is operational reality in various advanced sectors. Programs like Pragati demonstrate that sustainability starts from the agricultural supply chain, European projects like Bio.3DGREEN accelerate the introduction of new biopolymers through multidisciplinary research and standardization, while platforms like Virtucycle close the loop on the high-performance materials life cycle.

These concrete examples show that the industry already has the tools and partnerships necessary to transform bio-based materials from a research niche into a scalable solution. The key to success lies in integrating diverse expertise, independent certification, and creating ecosystems that connect all actors in the value chain.

Discover how your company can integrate these solutions into its production processes, by evaluating partnerships with structured programs that guarantee both sustainability and validated industrial performance.
