ContiTech uses recovered carbon black from Bolder Industries in conveyor belts

ContiTech has started using recovered carbon black from Bolder Industries in its conveyor belt production across the Americas. The material, called BolderBlack, is produced from post-consumer and post-industrial rubber waste through thermal conversion. After a 12-month qualification process, the material met ContiTech's commercial standards for general-purpose conveyor belt cover compounds. Bolder says producing its rCB uses 98% less water and generates 86% fewer greenhouse gas emissions compared to virgin carbon black. The material is ISCC+ certified, which provides chain-of-custody traceability and mass-balance verification. This move shows that circular materials can meet the performance and cost demands of industrial manufacturing.

Good to see a major manufacturer actually qualifying recycled materials for production. The 86% emission cut claim is interesting, but I'd like to see the full LCA. Still, this is the kind of move that makes circular economy real.

The ISCC+ certification adds some credibility, but the real test is whether the cost holds up against virgin carbon black. If the price is right, other belt makers will follow. If not, it stays a niche.

Curious about the performance specs. Conveyor belts take a lot of abuse. If this holds up, it's a solid case for recycled materials in industrial applications. Wonder how the maintenance costs compare over the belt's lifetime.

Not directly grid related, but the emissions reduction is meaningful. 86% fewer GHGs from material production is a big deal if it scales. Would like to see numbers on energy use in the thermal conversion process.
