Why use Composite Xchange?
Trusted B2B Network
Every buyer and seller is verified before they can trade.
Circular by design
Keeps advanced materials in use instead of in a skip. Reuse retains far more value, and embodied carbon, than recycling.
Anonymous by default
Listings show a reference, not a company name. Post your material and you stay anonymous. Offer collection and your address is shared only after payment.
Save Time & Costs
Find the materials you need, when you need them.

A circular network for advanced materials
Carbon fibre carries significant embodied carbon long before it reaches a workshop. Scrapping it unused wastes all of that. Keeping it moving between the firms that can use it is the single most effective thing the sector can do.
Every trade here is recorded, so both sides can evidence what was diverted from waste and what was bought recovered rather than new.
Reuse before recycling
Material used as intended keeps far more of its value than any recovery process returns.
Traceable throughout
Where records exist, they travel with the material, so recovered stock stays qualifiable.
Evidence for tenders
Motorsport, aerospace and wind customers increasingly want diversion reported. Your trading data provides it.
