Recovered Carbon Black Storage

Recovered carbon black made from end-of-life tires has applications in the tire, rubber goods, plastics, and pigment industries.

Recovered carbon black made from end-of-life tires has applications in the tire, rubber goods, plastics, and pigment industries.

ASTM International’s recovered carbon black (rCB) committee (D36) has announced it is developing a proposed standard to guide users of rCB on how long the material can be stored and the effect that prolonged storage could have on the material.

Recovered carbon black is made from end-of-life tires and has applications in the tire, rubber goods, plastics, and pigment industries.

ASTM member Joe Hallett says the purpose of the proposed standard (WK73460) is to provide a better understanding of the shelf life of rCB so unnecessary disposal of good material can avoided.

“Many substances have a ‘best before date’ that guides users when a substance loses some of its original performance or properties,” he says. “This guidance does not prevent use after this date but informs users that extra checks may be required before use to ensure it is still suitable for their application.”

Hallett says the purpose of the proposed standard will be to inform users of rCB that after 12 months, the material should be checked to ensure it is still suitable for use.

Interested parties are invited to join in the development of WK73460. In particular, the committee is seeking data from users and producers indicating that the performance of their products is not affected by age.

The D36 committee contact is Melissa Marcinowski at 610-832-9626 and mmarcinowski@astm.org.

ASTM says this effort directly relates to the United Nations Sustainable Development Goal No. 12 on responsible consumption and production.

Shelf-Stable Recovered Carbon Black

As ASTM D36 drafts WK73460 to define rCB storage and shelf life, producers need consistent, high-quality recovered carbon black.

Klean’s tire pyrolysis produces recovered carbon black that substitutes virgin carbon black in tires, rubber and plastics.

Why Choose Klean Industries’ Recovered Carbon Black?

✅ Consistent rCB quality for tire, rubber, plastics and pigment applications.
✅ Lower carbon footprint than virgin carbon black production.
✅ 8 rCB facilities built in India in the past 2 years.
✅ Feasibility studies and turn-key delivery for new rCB capacity.
