Revolutionary Biotech Process Recycles Carbon Fiber, Turning Waste into Valuable Resources
Table of Contents
Carbon fiber, a material known for its strength and lightweight properties, is now being reimagined through a groundbreaking biotechnological process.This innovation, detailed in the Journal of American Chemical Society, offers a sustainable solution to recycling carbon fiber reinforced polymers (CFRPs), a material widely used in industries ranging from aerospace to sports equipment.
Carbon fiber, composed of strands of carbon atoms bonded together in a matrix, has long posed challenges for recyclers. “It’s usually a woven material combined with a matrix, frequently enough made of epoxy or polystyrene, that holds it together,” explained Berl Oakley, Irving S. Johnson Distinguished Professor of Molecular Biology at the University of Kansas. “The goal is to recover the fabric for reuse and dissolve the matrix without creating something toxic or wasteful. Ideally, you want to reclaim value from it.”
A New Approach to Recycling Carbon Fiber
Oakley and his collaborators at the University of Southern California have developed a chemical procedure that effectively breaks down and removes the matrix from CFRPs. The recovered carbon fiber plies exhibit mechanical properties comparable to those of new manufacturing substrates. One of the major byproducts of this process is benzoic acid, which the researchers have found a way to repurpose.
To maximize the value of these byproducts, oakley has genetically modified the fungus Aspergillus nidulans to consume benzoic acid, producing a valuable chemical compound called OTA (2Z,4Z,6E)-octa-2,4,6-trienoic acid). “This represents the first system to reclaim a high value from both the fiber fabric and polymer matrix of a CFRP,” the researchers stated in their paper.
Turning Waste into Valuable Compounds
OTA, the compound produced by the modified fungus, has potential applications in medicine, including antibiotics and anti-inflammatory drugs. “OTA can be used to make products with potential medical applications, like antibiotics or anti-inflammatory drugs,” said Clay Wang, lead author of the study and professor at the University of Southern California. “This discovery is important because it shows a new, more efficient way to turn what was previously considered waste material into something valuable that could be used in medicine.”
oakley and his team are now focused on improving the efficiency of their specialized fungus, with an eye on scalability and profitability. “Since this work began, we’ve developed strains that are actually better than the original ones,” Oakley noted. “These newer strains will likely give better results, but we’ll need to do lots of work to engineer this process into the improved strains.”
Collaborative Effort Across institutions
The research was a collaborative effort, with Oakley working alongside graduate student Cory Jenkinson at the University of Kansas. At USC, Wang’s co-authors included Clarissa Olivar, Zehan Yu, Ben Miller, Maria Tangalos, Steven Nutt, and Travis Williams. This interdisciplinary approach has paved the way for a sustainable and economically viable solution to the growing challenge of carbon fiber waste.
As industries continue to seek sustainable solutions, this innovative recycling method could revolutionize how we manage and repurpose carbon fiber, turning what was once waste into a valuable resource.

Interview: revolutionizing Carbon Fiber Recycling with Biotech Innovation
Carbon fiber, renowned for its strength and lightweight properties, has long been a challenge to recycle. However, a groundbreaking biotechnological process, detailed in the Journal of American Chemical Society, is redefining how we manage carbon fiber reinforced polymers (CFRPs). This innovative approach not only recycles carbon fiber but also transforms waste into valuable resources, with potential applications in medicine and beyond. Join us as we delve into this revolutionary technology with Berl Oakley, Irving S.Johnson Distinguished Professor of Molecular Biology at the University of Kansas,and Clay Wang,lead author of the study and professor at the University of Southern California.
Introducing the challenge of Carbon Fiber Recycling
Senior Editor: Dr. Oakley, can you explain why carbon fiber has been such a challenge for recyclers?
Dr. Oakley: Absolutely. Carbon fiber is typically a woven material combined with a matrix, often made of epoxy or polystyrene, which holds it together. The challenge lies in recovering the fabric for reuse while dissolving the matrix without creating something toxic or wasteful. Ideally,we want to reclaim value from it.
The New Biotech Approach to Recycling
Senior Editor: Dr.Wang, can you tell us about the new chemical procedure you and Dr. oakley developed to address this challenge?
Dr. Wang: certainly. our procedure effectively breaks down and removes the matrix from CFRPs. The recovered carbon fiber plies exhibit mechanical properties comparable to those of new manufacturing substrates. One of the major byproducts of this process is benzoic acid,which we have found a way to repurpose.
Turning Waste into Valuable Compounds
Senior Editor: That sounds interesting. How does the repurposing of benzoic acid work, and what are its potential applications?
Dr. wang: We genetically modified the fungus Aspergillus nidulans to consume benzoic acid, producing a valuable chemical compound called OTA (2Z,4Z,6E)-octa-2,4,6-trienoic acid. OTA has potential applications in medicine, including antibiotics and anti-inflammatory drugs. This represents the first system to reclaim high value from both the fiber fabric and polymer matrix of a CFRP.
Future directions and Scalability
Senior Editor: Dr. Oakley, what are your plans for scaling this process and making it more efficient?
Dr. Oakley: We are focused on improving the efficiency of our specialized fungus, with an eye on scalability and profitability. As this work began, we’ve developed strains that are actually better than the original ones. These newer strains will likely give better results,but we’ll need to do lots of work to engineer this process into the improved strains.
Collaborative Effort Across Institutions
Senior Editor: It’s clear that this research is the result of a collaborative effort. Can you tell us more about the team behind this innovation?
Dr. Oakley: Certainly. The research was a collaborative effort, with me working alongside graduate student Cory Jenkinson at the University of Kansas. At USC, Dr. Wang’s co-authors included Clarissa Olivar, Zehan Yu, Ben Miller, Maria Tangalos, steven Nutt, and Travis Williams. This interdisciplinary approach has paved the way for a sustainable and economically viable solution to the growing challenge of carbon fiber waste.
Conclusion: A Sustainable Future
Senior Editor: As industries continue to seek sustainable solutions, how do you see this innovative recycling method impacting the future of carbon fiber management?
Dr. Wang: This method could revolutionize how we manage and repurpose carbon fiber, turning what was once waste into a valuable resource. It’s a step towards a more sustainable future, where we not only recycle but also create new opportunities from what was previously considered waste.
Senior Editor: thank you both for sharing your insights. This truly is a revolutionary approach, and we look forward to seeing how it evolves in the coming years.
