But like the other three defined, sustainable CB production methods, it comes with some "demerits" in that specific grades of CB—and there can be many, in different parts of the tire—cannot be reproduced or are too costly compared to furnace black production.
And it is one reason why so little rCB—less than 1 percent on the global market—finds its way into new tires.
The realization that no business is an island in pursuit of a greener supply chain is a major step for tire producers.
As a representative from Bridgestone told Rubber News, "We want to be customers and not necessarily investors in this space."
But getting to 2050 with a clean slate, literally, will take continued cooperation to balance protection of the planet, consumer safety and continued profitability.
Any one of the three could be considered "non-negotiable."
Like the dreaded "performance triangle" that tire makers have tweaked to meet safety needs, the "sustainability triangle" is proving to be just as difficult to mold, as each corner can be inversely related.
The tire industry and its partners have succeeded in critical situations in the past.
The stated sustainability goals of the tire industry present perhaps the greatest challenges with the highest stakes, hurdles that upstream and downstream players have no choice but to clear once again.
