New Revenue Streams & Save Costs with Circular Material Flows – 7 Successful Case Studies & Actionable Takeaways
As businesses continue to operate in resource confined environment, adopting circular strategies, companies can unlock new revenue streams, reduce operational costs, enhance supply chain resilience, and meet the growing consumer demand for sustainable products. Here’s how circular material flows can reshape your business strategy.
What are Circular Material Flows
Circular material flows are systems designed to repair, recover, recycle and resume materials at every stage of a product’s lifecycle. They break from the traditional linear “take-make-dispose” models, instead aiming to create closed loops where waste can become a resource. Think of it as the real-life embodiment of the concept, “one man’s trash is another man’s treasure”. By continually cycling materials back into production, businesses can minimise waste whilst maximizing resource efficiency.
Key Principles of Circular Material Flows
Extended Product Lifecycles: Products are designed to last longer, be repaired, or easily disassembled for recycling (ie. designed for durability, modularity, and recyclability)
Material Recovery: End-of-life products are recovered, and their materials are reintegrated into production processes.
Cross-Sector Symbiosis: Byproducts from one industry become inputs for another, creating mutually beneficial relationships.
Data-Driven Optimization: Integration of data analytics tools like Material Flow Analysis (MFA) and Circular Transition Indicators (CTI) to track material usage and identify inefficiencies
Collaborative Partnerships: Businesses, governments, and consumers work together to create closed-loop systems.
7 Successful Case Studies in Circular Material Flows:
1. Novelis: Closing the Aluminum Loop
Strategy: Novelis, a global leader in aluminum rolling and recycling, invested €200 million in a state-of-the-art recycling center in Germany. This facility processes scrap aluminum from customers, turning it into high-quality material for new products.
Impact:
- Recycles 400,000 metric tons of aluminum annually.
- Saves 3.7 million metric tons of CO₂ emissions each year.
- Increased recycled content in products from 30% in 2009 to 53% by 2016.
Practical Takeaway: To replicate this, businesses should embed circularity into customer relationships. Offer incentives for returning end-of-life products or materials, and ensure your recycling processes add value to your customers’ operations. By seeing customers as suppliers, companies can improve supply chain resilience, reduce reliance on virgin materials, and mitigate price volatility in virgin aluminium markets, providing long-term financial stability. This vertical integration of recycling infrastructure can create a win-win scenario: customers benefit from reduced waste disposal costs, while companies can secure a steady supply of high-quality resources ie. scrap.
2. FAKRO PP: PVC Waste to Window Frames
Strategy: FAKRO PP partnered with Primo Profile to recycle PVC manufacturing waste into high-strength profiles for window frames, exemplifying the power of cross-sector symbiosis. By collaborating with a supplier to repurpose manufacturing waste, FAKRO PP turned a cost center (waste disposal) into a revenue stream (recycled materials). This required close collaboration on material specifications and quality control to ensure the recycled PVC met performance standards.
Impact:
- 63% of FAKRO’s window frames now use recycled PVC.
- Matches the strength of non-recycled materials while reducing landfill waste.
Practical Takeaway: Cross-sector symbiosis—where one company’s waste becomes another’s raw material—enhances resource efficiency and aligns with environmental, social, and governance (ESG) goals. Identify strategic partners within your value chain who can help you close material loops. Focus on creating mutually beneficial agreements that align with both parties’ operational and sustainability goals.
3. TerraCycle: Recycling the Non-Recyclable
Strategy: TerraCycle specializes in recycling hard-to-recycle materials, such as cigarette butts, through brand-sponsored programs. TerraCycle’s model thrives on innovative funding mechanisms. By partnering with brands to sponsor recycling programs, TerraCycle shifts the financial burden away from consumers and municipalities. This not only makes recycling accessible but also enhances brand loyalty and corporate sustainability profiles.
Impact:
- Collected over 100 million cigarette butts, diverting them from landfills.
- Enhanced corporate sustainability profiles for partner brands.
Practical Takeaway: Gamification and brand collaboration can drive consumer engagement in circular practices, turning waste into a resource. Explore creative financing models for circular initiatives. Consider co-branded programs or subscription-based services that engage consumers while sharing costs with partners.
4. Unilever: Reducing Virgin Plastic Use
Strategy: Unilever aims to make 100% of its plastic packaging recyclable, reusable, or compostable by 2025. Unilever’s approach highlights the importance of scalability and consumer acceptance. The company invested heavily in R&D to develop packaging that maintains product integrity while being recyclable or compostable. They also worked with retailers and waste management companies to ensure their packaging could be effectively recycled in existing systems.
Impact:
- 54% of plastic packaging met these goals by 2024.
- Reduced virgin plastic use by 12% since 2018.
Practical Takeaway: Transitioning to circular packaging requires a phased, iterative approach that balances sustainability goals with functional requirements. Begin with pilot projects to test packaging designs in real-world conditions, gathering data on performance, consumer acceptance, and recyclability. Use this feedback to refine materials and processes. Simultaneously, engage stakeholders—suppliers, manufacturers, retailers, and waste management partners—early in the design process to ensure scalability and alignment across the value chain. This collaborative, data-driven approach minimizes risks, avoids costly missteps, and ensures solutions are practical and impactful at every stage.
5. Mud Jeans: Lease Model for Denim
Strategy: Mud Jeans’ “Lease a Jeans” program encourages customers to return old jeans for recycling into new products, and is an example of shifting from ownership to access or Product-as-a-service models. By retaining ownership of the jeans, Mud Jeans can control their end-of-life processing, ensuring materials are recycled or reused. This model also fosters deeper customer relationships, as leasing requires ongoing engagement.
Impact:
- Saved 300 million liters of water annually.
- High customer adoption rates for the leasing model.
Practical Takeaway: Consider product-as-a-service models for high-value, durable goods. The model can extend material lifecycles and reduce resource consumption while fostering customer loyalty. Use data from returned products to improve design and material selection, creating a feedback loop that enhances circularity.
