Transforming end-of-life tires into useful industrial materials.
Old tyres are made of non-biodegradable materials like rubber, steel, fibers, and chemicals, and they take up significant space in landfills due to their bulk
Discarded tyres are difficult to burn and can cause fires that are hard to extinguish
When they decompose, tyres release harmful gases, leachate, and pests, polluting soil, water, and farmland
The production of carbon black from tyres emits CO2 and consumes large amounts of fossil fuels and water
Most existing tire-recycling methods—such as shredding, burning, or basic pyrolysis—reduce waste but fail to produce consistent, high-quality materials. The resulting outputs are often degraded, contaminated, or unsuitable for reuse.
Because of these limitations, most recycled carbon black ends up in low-value applications such as asphalt or plastics. This dependence prevents the tire industry from reducing its reliance on virgin carbon black, locking in fossil-fuel use and slowing progress toward a truly circular economy.
Tests confirm Black Pearl rCB can replace virgin grades like N550 and N660, matching strength, hardness, and curing performance with up to 100% substitution potential.

Reliable rCB turns old tires into feedstock for new ones, reducing fossil use, cutting emissions, and advancing a truly circular industry.
Achieved 100% substitution of N660 carbon black with Black Pearl rCB in SBR-1502 rubber and agricultural tire carcass compounds (FB-6313R). Comparative testing against standard CB confirmed similar cure and physical properties.
Two Black Pearl rCB samples were tested in SBR-1502 compounds against N660. The results showed mechanical performance within the N660 ranges, confirming the fillers’ suitability as direct substitutes in rubber applications.
Substituted 50% of N550 carbon black with Black Pearl rCB in passenger car tire carcass compounds. Both raw rheological and vulcanized rubber mechanical tests demonstrated nearly identical performance.
Replaced 50% of standard N550 carbon black with recovered Black Pearl rCB in hermetic layers, sidewalls, and agricultural tire carcasses. Results showed comparable rheological properties and mechanical performance of vulcanized rubber.
