Sustainable carbon black
A method for producing a more sustainable carbon black (sCB) by producing it from a circular raw material instead of a finite raw material is presented. The method utilizes tire pyrolysis oil produced from end-of-life tires, said to be an attractive alternative feedstock source versus traditional petroleum products.

Truck tire tread compound development using low hysteresis carbon black
Performance properties of a surface treated low hysteresis carbon black (Continext-LH) compound in a natural rubber tread formulation are compared with those of a conventional N234 low hysteresis version and show that the new material had significantly improved rolling resistance and directional improvement in damage resistance without negative effects or trade-offs in wet traction and wear resistance.

A new low CO2 reinforcing filler
Ferro-Alloy Resources (FAR), a London, U.K. listed mining company with operations in Kazakhstan, recently announced plans to produce a new type of reinforcing filler as a carbon black substitute (CBS). When partially substituted for carbon black in a typical rubber formulation for passenger tire side-walls, there was no significant deterioration of performance in a battery of tests that were conducted, and there were several advantages. Moreover, there is a very significant reduction in CO2e emissions in the production of this material compared with the production of carbon black.
