Closed Composites is a clean technology company developing sustainable solutions for carbon fiber reinforced polymer (CFRP) waste. Using a proprietary chemolysis processes, we recover clean, high-quality carbon fiber and valuable resin components from amine-linked epoxy composite scrap and end-of-life materials - enabling reuse, repair, and circular manufacturing across aerospace, automotive, energy, and industrial applications. 

We have demonstrated the recovery of both monomeric fine chemicals from the organic matrix as well as high quality, ordered carbon fibers in their original format at bench and commercial lab scale. These approaches can be tailored to expired prepregs, fully cured end-of-life materials, as well as repair applications. 

Recovered fibers and organics have been re-made into composite parts that retain 92% or greater of their original performance characteristics.  Organic yields so far exceed 70% and solvent reuse has been demonstrated at 5X without a decline in fiber cleanliness.

Initial analysis shows a 40% decrease in cost and a 70% reduction in embodied energy (GHG) is possible.

Closed Composites is advancing its technology toward pilot and commercial scale, targeting industry-specific needs and material formulations. We are actively seeking development partners across the composite manufacturing ecosystem including resin, fiber, prepreg, and finished part manufacturers, as well as recyclers and resource recovery companies.

If you are interested in collaboration, co-development, or learning more about our technology, we welcome the conversation.
