Remanufacturing Insights: Shaping a Sustainable Future

On April 14, 2025, industry experts from leading companies in engine manufacturing gathered for an insightful webinar focused on the significant role of remanufacturing in advancing sustainability within the circular economy. Organized by the Engine Technology Forum, this session featured representatives from renowned organizations like Caterpillar, Cummins, John Deere, Johnson Matthey, and Stanadyne, who shared their valuable insights on remanufacturing practices.

Importance of Remanufacturing in the Circular Economy

The discussion highlighted the fundamental ways in which remanufacturing contributes to sustainability. Allen Schaeffer, Executive Director of the Engine Technology Forum, opened the session by emphasizing how remanufacturing internal combustion engines (ICEs) aligns with broader environmental goals. This encompasses enhancing energy efficiency, achieving near-zero emissions, and utilizing renewable biofuels, thereby elevating the industry’s contribution to a sustainable future.

Attendees included government officials, researchers, academics, NGOs, and representatives from the trucking, engine, and equipment sectors. This diverse audience reflected the universal importance of remanufacturing and its capacity to generate value not only for manufacturers but also for the environment and society as a whole.

The Remarkable Process of Remanufacturing

During the webinar, several key speakers provided insights into their organizations' remanufacturing processes. Patricia Covington from Cummins illustrated how remanufacturing has been integral to the company since the 1960s. The process begins during the design phase of new products, defining a ten-step approach that further mitigates supply risks, ensuring customer service continuity during periods of uncertainty.

John Deere's Kevin Schrag discussed the company's extensive remanufacturing operations, with over 450,000 core receipts every year. He pointed out that remanufacturing provides significant advantages to customers and dealers while saving valuable resources. Schrag defined remanufacturing as a rigorous industrial process that returns obsolete products to 'like-new' or 'better-than-new' conditions, emphasizing that it should not be confused with mere recycling or repairing.

Caterpillar’s Jeff Sutherland spoke about the company’s involvement in REMADE, a U.S. Department of Energy-funded project aiming to enhance remanufacturing software for design engineers. This project illustrates Caterpillar's commitment to creating designs that facilitate remanufacturing from the initial development stages, further emphasizing the critical role that innovation plays in sustainability.

Stanadyne's Srinu Gunturu provided insights into the company’s vision, underlining its strong dedication to sustainability through advanced remanufacturing methods. The firm retains up to 85% of the original materials in diesel engine parts, considerably minimizing waste and conserving resources—a practice that exemplifies effective circular economy principles.

Platinum Group Metals and Sustainability

Highlighting the contributions of platinum group metals (PGMs) in reducing transport emissions, Marge Ryan from Johnson Matthey elaborated on the intricate processes of recovering PGMs through remanufacturing. Approximately 60% of PGMs used in new products and catalysts globally are sourced from recycled materials, shaping a robust supply chain that supports environmental sustainability.

Conclusion

The insights shared during this webinar not only underscored the pivotal role of remanufacturing in supporting the circular economy but also served as a call to action for continuous improvement and innovation. As industries strive toward greater sustainability, the practices discussed highlight a pathway for integrating ecological considerations into core operational frameworks.
