Circular
Recovered carbon black and circular carbon
Recovered carbon black returns the carbon black in end-of-life tyres to rubber and plastics products. Budcon International supplies rCB with the test documents buyers need to qualify it.
How rCB is made
- Tyre processing — end-of-life tyres are shredded, and steel and textile are removed.
- Pyrolysis — the rubber is heated without oxygen; it separates into oil, gas, steel and a solid carbon residue.
- Refining — the carbon residue is milled to size and may be pelletised for handling.
- Testing — each lot is tested to ASTM methods and supplied with a COA.
What rCB offers buyers
- Recovered content for products and customers that ask for circular materials.
- Scope 3 data — raw materials are a large part of a compound’s footprint; rCB is one lever buyers examine in product carbon footprint work.
What we do not claim
CO₂ savings for rCB depend on the pyrolysis process, energy source, transport and the life-cycle method used. Budcon International does not publish a generic CO₂ reduction figure. If your reporting needs a product-specific figure, ask for the documentation available for the current rCB lot and its basis.
The test documents available for rCB (COA, TÜV SÜD REACH/RoHS verification, IRMRA PAH report, REACH SVHC declaration) are listed on the recovered carbon black page.
