ContiTech wrapped a 12-month qualification cycle that puts Bolder Industries' BolderBlack into general-purpose conveyor belt cover compounds at the group's Americas plants, the companies announced October 6.

The integration places a recovered carbon black (rCB) into supply chains that depended on fossil-derived carbon black for more than a century. Continental's industrial rubber subsidiary runs its North American operations out of Fairlawn, Ohio. Bolder operates its thermal conversion facility in Boulder, Colorado.

What did the qualification process cover?

ContiTech and Bolder teams ran production trials across the past year. They tested processing behavior and material performance against the thresholds industrial buyers require before scaling a new raw material input. Bolder says the trials confirmed BolderBlack met the full performance bar.

The output now feeds cover compounds bound for customers in energy, oil and gas, mining, and industrial manufacturing. Those end markets are working through their own emissions-reduction commitments, which ContiTech executives framed as the demand driver.

How does BolderBlack compare with virgin carbon black?

Bolder produces BolderBlack from 100 percent post-consumer or post-industrial rubber waste through a proprietary thermal conversion process. The company benchmarks the route against virgin carbon black production with two figures:

• approximately 98 percent less water use
• approximately 86 percent fewer greenhouse gas emissions

BolderBlack carries ISCC PLUS certification. Independent lifecycle assessments back the emissions profile, the company says.

Who is pushing the deal, and why now?

"Sustainability in industrial manufacturing must be earned through performance, quality, consistency and cost," said Mathew Augustine, head of product development for industrial solutions Americas at ContiTech. "By integrating BolderBlack into our conveyor belt production, we are demonstrating that circular materials can meet the rigorous standards our customers expect. This partnership with Bolder Industries shows that circularity and competitiveness can go hand in hand in real-world manufacturing."

Bolder Industries CEO Tony Wibbeler framed the same point from the supplier side. "Manufacturers don't adopt materials just because they're sustainable," he said. "They select materials because they perform. BolderBlack doesn't ask manufacturers to compromise, and in many applications, it outperforms. The market is getting its answer and we're proud to partner with Continental."

Where does the deal rank in the rCB market?

Neither company disclosed volumes, tonnage, or the share of BolderBlack in ContiTech's Americas cover-compound mix. The deal is the first commercial-scale integration of a thermal-rCB product into ContiTech's general-purpose conveyor belt line, both companies said.

The integration matters for the wider rubber-recovery sector, which has long pitched rCB as a drop-in candidate but rarely cleared performance benchmarks at production scale. Bolder's pathway is one of several under commercial evaluation across tire-derived and post-industrial feedstock streams.

What milestone decides what happens next?

Bolder and ContiTech now have a commercial-scale reference point to defend. The next decision point is the supply volume and compounding share ContiTech books for 2027, which will determine whether the partnership stays a regional line item or extends to ContiTech's European and Asian conveyor belt operations. Neither company has set a public deadline for that expansion.

Industry pressure on Scope 3 emissions reporting will sharpen the case. As mining, oil and gas, and bulk materials handlers translate emissions targets into supplier specifications, the demand signal moves from pilot to procurement contract. ContiTech's willingness to put a name-brand rCB into a high-wear product such as a conveyor belt cover is one of the few public data points showing the translation has begun on the rubber side.
