rCB: Black Gold from End-of-Life Tires

Conventional carbon black (vCB) is a key raw material in tire manufacturing,

but its production heavily relies on fossil fuels and generates significant carbon emissions.

Recycled carbon black (rCB), on the other hand, is a sustainable alternative extracted

from end-of-life tires through thermochemical recycling.

Due to its exceptional economic and environmental value, it is widely regarded as "Black Gold" in the industry.

The production of rCB primarily relies on high-temperature pyrolysis technology,

which converts waste rubber into high-value materials:

Pre-treatment & Pyrolysis: End-of-life tires are shredded and magnetically separated to remove steel wires,
then thermally decomposed at 400–800°C in an oxygen-free environment.
Product Separation: The long rubber chains break down, producing pyrolysis oil,
combustible gas, and solid residue (crude carbon black mixed with steel wire).
Refining & Modification: The crude carbon black undergoes deep purification processes such as grinding,
ash removal, and desulfurization, followed by pelletizing to produce high-quality finished rCB.

Compared to traditional processes, rCB not only significantly reduces carbon emissions

but also finds wide applications across multiple industrial sectors:

As a reinforcing filler, rCB can replace up to 60% of virgin carbon black in passenger car and truck tires.

Major players like Michelin and Pirelli have already scaled up its use in high-performance tires.

In rubber flooring, sealing rings, conveyor belts, and anti-vibration components,

rCB can achieve 100% replacement, reducing costs while meeting stringent physical performance requirements.

rCB significantly enhances UV resistance, mechanical strength, and provides coloring effects for plastics.

It is widely used in automotive interiors, engineering plastics, and conductive packaging.

With excellent tinting strength and hiding power, rCB serves as a deep black pigment for printing inks,

while also providing corrosion protection and anti-aging properties for architectural coatings.

Emission Reduction: Producing 1 ton of rCB can reduce approximately 2.5 tons of CO₂ emissions,
while saving up to 90% of virgin petroleum resources.
Waste Recycling: It effectively addresses the landfill challenge posed by
billions of end-of-life tires worldwide each year, driving a closed-loop circular economy in the rubber industry.
Market Growth: Driven by increasingly stringent environmental regulations and
sustainability commitments from automakers, the global rCB market is expected to grow at a
compound annual growth rate exceeding 10%.
