The ASTM recently created a specialist D36 committee on recovered Carbon Black (rCB). The D36 Committee held its first meeting in advance of the European Tyre Recycling Conference in Brussels on the 23rd March.
This is seen as a major step toward creating standards for the rCB sector. Standards that would allow the many pyrolysis operators to work towards a set goal and ensure that they all used a standard method of testing.
42 delegates attended the inaugural meeting of the committee including technicians, investors and observers.
There also were two subcommittee meetings of D36 in Brussels — one to evaluate current carbon black standards from ASTM Committee D24 and determine how much of that standard can be applied to rCB, and the other to discuss the development of standards for rCB.
Pyrolysis is defined as the thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen.
More specifically for the rubber industry, pyrolysis is the technology of breaking down rubber into its component carbon black, oil and steel under high heat in a controlled, often inert environment.
The next meetings for D36 are scheduled for June 15 in Toronto; Dec. 6 in New Orleans; June 28, 2018, in San Diego; and Dec. 6, 2018, in Washington, D.C.
