Current recycling strategies use extreme temperatures (up to 800°C) to destroy the polymer binding, leaving the carbon fibers to be collected. Although effective, this process often requires shredding the fibers and risks damaging them, condemning them to lower-quality applications later on. It also fails to recover any of the polymer, instead converting it into harmful greenhouse gasses. The curing chemistry of the polymer is what binds this material together, so we believe a chemical perspective should be taken when considering how to disassemble it!
ClosedComposites is developing metal catalysts that can use oxygen from air to specifically undo the key bonds formed during the curing process. Through the power of catalysis, we can employ milder reaction conditions (temperatures < 250°C) and recover carbon fibers that remain in pristine condition for future applications and organic compounds that we can recycle to cast future resins. We assert that a closed recycling loop for these amazing materials is achievable.
ClosedComposites was created because we identified a sustainability issue that we believe we have the chemical and engineering expertise to solve. We apply a dual catalyst system based on abundant metals to catalytically disassemble CFRPs and accrue the maximum amount of value from the abundance of CFRP production scrap and products that exist. From this "waste", we offer the consumer the ability to recover high quality recycled carbon fibers for future applications, reducing the need for purchasing expensive virgin fibers, and helping them reduce their environmental footprint. Derivatized polymer monomers can be easily isolated from the reaction solution and converted to bisphenol A, a common feedstock chemical for these epoxy resins.
The demand for our technology will always be present if CFRPs are in demand, and current data shows that CFRPs will be around for a while: Carbon Composites reports the global CFRP turnover in 2016 to be $13.23 billion dollars and is expected to grow 10-13% for following years. Considering that up to 30% of purchased CFRP material is cut as scrap during production, there will be a large market for recycling CFRP production waste and the final product at the end of its service life for decades to come.
We are open to meeting up to grab a coffee, or just to chat. We would really enjoy your feedback and insight into our venture and would be happy to discuss anything that you are currently working on to see if we can be of service!
