The polymer-based composite industry is at a pivotal moment as it tackles the dual challenges of growing demand and the urgent need for sustainability. Composites, particularly Fiber Reinforced Plastics (FRPs), are essential materials in industries ranging from aeronautics and automotive to construction and space due to their superior strength-to-weight ratios and durability. However, these same properties pose significant challenges when it comes to recycling and achieving a circular economy. The Cradle-ALP Circular Transformation Roadmap for polymer-based composites aims to address these challenges, guiding the industry through a strategic shift towards sustainability over the next decade.

The Cradle-ALP project, part of the Interreg Alpine Space programme, has developed a comprehensive roadmap that spans from 2024 to 2034. This roadmap is designed to guide the polymer-based composite industry towards a sustainable future through a phased approach that includes short-term, mid-term, and long-term goals. Each phase is tailored to address specific challenges and lay the foundation for the next steps in the circular transformation.

Short-Term (2024-2026): Laying the Foundation for Circularity

The short-term phase focuses on establishing the foundational elements necessary for a successful circular transformation.

Key activities include:

• Technology: The development of a public database on second-life and end-of-life solutions for composites, coupled with the extension of bio-sourced materials. This will provide SMEs with access to critical information and resources for integrating circular practices.
• Business Models: Encouraging collaboration between manufacturers, plant fibre suppliers, and research institutions to build a strong supply chain for biobased composites. Financial support mechanisms, such as tax relief for investments in recycling machinery, will be essential for managing end-of-life composite waste.
• Legal and Political Framework: Implementing Extended Producer Responsibility (EPR) schemes and establishing standards for recycled composites materials. This will create a regulatory environment conducive to the growth of circular practices within the industry.

Mid-Term (2026-2029): Scaling and Integration of Circular Practices

The mid-term phase builds on the short-term achievements by introducing more complex solutions and scaling up circular practices.

Key activities include:

• Technology: Expanding the public database to include second-life solutions for composites and developing infrastructure for waste-to-energy recovery of biomaterials. Additionally, the implementation of design practices that prioritize modularity and material separation will be crucial for circularity.
• Business Models: Creating markets for biobased composites by fostering demand among manufacturers and consumers. Training programs focused on eco-design will help instil a culture of sustainability within the industry.
• Legal and Political Framework: Aligning European regulations for end-of-life management of composites and developing ISO standards for recycling and reusing composite materials. These actions will provide a consistent framework across the EU, facilitating cross-border collaboration and innovation.

Long-Term (2029-2034): Achieving Structural Changes for a Circular Economy

The long-term phase aims for deep structural changes that will entrench circular practices within the industry.

Key activities include:

• Technology: Developing a public database of the technical properties of recycled composite materials and ensuring that all composite products are designed for easy dismantling and reuse. Advanced technologies for assessing the condition and performance of composite materials at their end-of-life will also be mature by this phase.
• Business Models: Implementing pilot projects for composite waste collection and creating harmonized Design for Circularity Guidelines for stakeholders across the value chain. These initiatives will support the full integration of circular practices into the industry’s operations.
• Legal and Political Framework: Banning the landfilling of high-value composites waste and implementing EU regulations that require the inclusion of recycled content in new composite products. Transparent standards will ensure the safe and sustainable use of additives and substances within the industry.

The Cradle-ALP Transformation Roadmap offers a clear and actionable pathway for the polymer-based composite industry to transition towards a circular economy. By focusing on technology, business models, and regulatory frameworks, the roadmap provides a holistic approach that addresses the industry’s most pressing challenges.

Why This Circular Transformation Matters for SMEs

Small and Medium-sized Enterprises (SMEs) are the backbone of the polymer-based composite industry, driving innovation and growth. However, they face unique challenges in adopting circular practices due to limited resources and the complexity of the materials they work with. The transformation roadmap offers these SMEs a pathway to sustainability, helping them to remain competitive in a market increasingly shaped by environmental regulations and consumer demand for green products.

Ultimately, this transformation will secure a resilient, eco-friendly future for the industry and the Alpine region, aligning economic growth with environmental stewardship.
