Tyre pyrolysis carbon black industry is a rapidly growing sector that plays a crucial role in the recycling and upcycling of waste tyres. Pyrolysis, a thermochemical process that decomposes organic materials at high temperatures in the absence of oxygen, is used to convert scrap tyres into valuable products such as oil, gas, and carbon black. Among these, carbon black is a particularly important byproduct, and its use in various industries contributes to sustainability and circular economy initiatives.
What Is Pyrolysis Carbon Black?
Pyrolysis carbon black, also known as recovered carbon black (rCB) refers to carbon black recovered from waste rubber or used tires through the tire pyrolysis plant. Compared to traditional carbon black, rCB exhibits similar properties and offers a wide range of applications. Its key physical and chemical properties include:
- Black Granular structure
- High carbon content
- Low ash content
- High specific surface area
- Porous structure
- Good electrical conductivity
- Strong chemical stability
- Recyclable
- Suitable for various processing methods
How Carbon Black is Extracted Through Pyrolysis?
- Collection and Preprocessing of Waste Tires
According to the feed requirements of pyrolysis equipment, cut waste tyres into small pieces or particles to ensure optimal efficiency for the subsequent pyrolysis process. - Pyrolysis Process
In an oxygen-free or low-oxygen environment, heat waste tires with high temperatures (typically between 400°C and 600°C). During this process, the organic materials in the tires decompose into gaseous, liquid, and solid products. The primary solid product is carbon black, with a small amount of steel wire. - Carbon Black Collection
Collect and store the produced carbon black in a dry, ventilated, and well-sealed environment to prevent it from reacting with moisture in the air, ensuring its quality remains stable.
Potential Applications of Pyrolysis Carbon Black
So far, the largest consumer of carbon black has been the tire industry, accounting for nearly 70% of global carbon black production, which is used in the manufacture of new tires. An additional 20% is used in the production of technical rubber products, such as seals, molded parts, and shock absorbers. The remaining 10% of carbon black is an essential raw material for plastics, carbon powders, and inks.
| Industry | Target Customer Groups | Demand Motivation |
|---|---|---|
| Tire Manufacturing | Tire manufacturers are one of the main customers of pyrolysis carbon black. Especially those who aim to reduce raw material costs and minimize their carbon footprint are inclined to use pyrolysis carbon black as a partial substitute for traditional carbon black. |
|
| Rubber Products | Companies that produce industrial rubber products such as seals, rubber belts, rubber mats, etc., are also important customers of pyrolysis carbon black. | / |
| Plastic Processing | Pyrolysis carbon black is often used as a coloring agent and filler in the plastic industry, especially by manufacturers of plastic products that require consistent color. |
|
| Ink, Coatings, and Pigment Manufacturing | Pyrolysis carbon black is widely used in the ink, coatings, and pigment manufacturing sectors due to its coloring ability and cost advantages. Eco-friendly ink and coating manufacturers prefer to use pyrolysis carbon black. |
|
| Chemicals and Materials | Some chemical companies use pyrolysis carbon black as a filler or component in composite materials, widely applied in engineering plastics, conductive rubber, and other fields. |

Great Significance of Pyrolysis Carbon Black Production
Environmental Benefits:
- Reduction of Emissions: Pyrolysis transforms organic waste like plastics and tires into carbon black, effectively reducing waste disposal burdens and mitigating environmental pollution. This provides a sustainable solution, especially in handling tire and plastic waste.
- Low Environmental Impact: Compared to traditional methods like landfill or incineration, pyrolysis significantly reduces harmful gas emissions, particularly greenhouse gases (such as CO2), thereby minimizing atmospheric pollution.
- Energy Substitution: The oil and gas produced during the tyre pyrolysis process can be used as alternative energy, decreasing dependence on fossil fuels and further reducing greenhouse gas emissions, contributing to a lower overall carbon footprint.
Economic Benefits:
- Resource Recovery: Pyrolysis not only extracts carbon black but also produces valuable by-products such as oil and gas. These by-products can be used for energy recovery or further processing, promoting resource recycling and supporting the principles of a circular economy.
- Reduced Raw Material Costs: Carbon black is a key industrial material widely used in industries like rubber, ink, coatings, and plastics. By extracting carbon black through pyrolysis, raw material costs can be significantly reduced.
- Economic Profit: In addition to carbon black, the by-products like oil and gas can be sold, generating additional economic revenue.
In summary, pyrolysis carbon black extraction provides both significant environmental and economic advantages, promoting resource recovery, energy use, and contributing to sustainability.
Driving Factors Behind the Development of the Pyrolysis Carbon Black Industry
Policy Support
Policy guidance plays a crucial role in developing the pyrolysis carbon black industry, especially in waste management, environmental protection, and resource recovery. Relevant policies include:
- United Nations Sustainable Development Goals (SDGs): Goals 12 (Responsible Consumption and Production) and 13 (Climate Action) encourage the adoption of circular and sustainable production models. As a circular material, pyrolysis carbon black helps reduce resource consumption and carbon emissions, contributing to sustainable development.
- European Automobile Manufacturers’ Association (ACEA) and American Automotive Manufacturers Association (AAMA): These industry organizations advocate for the use of more eco-friendly materials in the automotive sector. The application of pyrolysis carbon black in the production of tires and rubber products aligns with the industry’s demand for circular materials.
Technological Advancements
In recent years, advancements in tire pyrolysis and carbon black modification technologies have expanded the application scope of pyrolysis carbon black.
- Pyrolysis: With the maturation of tire pyrolysis production technology, precise temperature control, and the utilization of combustible gases, production costs have gradually decreased. The effect of economies of scale continues to grow, enhancing the industry’s overall competitiveness.
- Deep Processing of Carbon Black: Continuous improvements in ultrafine grinding, activation modification, and granulation processes have led to pyrolysis carbon black, after deep processing, achieving increasingly similar performance indicators to N330. As a result, its range of applications is steadily expanding.
Social Environment Factors
As global society’s focus on environmental protection continues to deepen, the application of pyrolysis carbon black, as a recycled product, has gained widespread support. The social and environmental factors influencing its development include:
- Increased consumer awareness of environmental issues;
- Growing public concern about waste management;
- Industry attitudes and a sense of social responsibility.
Economic Environment Factor
The global shift towards a green economy and sustainable development is gradually increasing the demand and competitiveness of pyrolysis carbon black in the global market.
- Global Economic Growth and Industry Demand
As the global economy recovers, the growth of infrastructure, automotive manufacturing, and consumer goods production is driving demand in industries such as rubber, plastics, and coatings, which are key users of carbon black. - Energy Price Fluctuations and Cost Pressure
The oil price fluctuations affect traditional carbon black production costs. In contrast, pyrolysis carbon black, relying on waste tires and other raw materials, has stable costs and offers a cost advantage. - Global Supply Chain Changes
The global supply chain has faced disruptions due to the pandemic, geopolitical tensions, and trade conflicts, leading to price increases and material shortages. Pyrolysis carbon black, however, is produced using local waste tires, ensuring supply stability. Additionally, as a recycled product, pyrolysis carbon black benefits from policies encouraging local production and reducing import dependency.
