Carbon Black (CB) is generally created from oil and gas and as such creates a high environmental footprint. The product is created when oil or gas is sprayed in very tiny jets into an incineration chamber where the material is incompletely combusted, very suddenly, leaving very small carbonized particles.

​CB is mainly used as a reinforcement agent in the manufacture of rubber tires, but it is also used as a pigment and, to a much lesser degree, as a food colourant when made from vegetable oils.​

ATS technology recaptures and purifies the CB in waste rubber tires, thereby reducing the requirement to create more virgin CB.
