What Is a Continuous Tyre Pyrolysis Plant?

A continuous tyre pyrolysis plant is a professional thermal decomposition equipment designed for large-scale, uninterrupted recycling of waste tyres. It realizes continuous feeding of tyre raw materials, continuous pyrolysis reaction, continuous discharge of products (pyrolysis oil, carbon black, syngas) and 24-hour non-stop operation through a fully automated, sealed system, converting waste tyres into high-value renewable resources efficiently and stably.

The essential difference between continuous and batch tyre pyrolysis plants lies in the continuity of the entire production process: batch plants require intermittent feeding, shutdown reaction, and manual discharge, while continuous plants achieve seamless connection of all links through automated control, fundamentally solving the problems of low efficiency and unstable output of batch equipment.

 

Raw Material Requirements for Continuous Tyre Pyrolysis

Clear raw material requirements are the premise for the stable operation of continuous tyre pyrolysis plants. Unlike batch plants that have relatively loose requirements, continuous systems have strict specifications for tyre raw materials—this is a core technical point that distinguishes professional manufacturers from inferior equipment suppliers.

Can whole tyres be used in a continuous system?

No, whole tyres cannot be used in a continuous tyre pyrolysis system. The continuous operation of the plant relies on the uniform, stable feeding of raw materials and the smooth progress of the pyrolysis reaction. Whole tyres have irregular shapes, large volumes, and uneven thicknesses, which will cause serious blockages in the continuous feeding system, destroy the sealed environment of the reactor, and even lead to equipment failure due to uneven heating. In addition, the steel wires and fiber layers in whole tyres cannot be separated in advance, which will affect the quality of pyrolysis products and increase the wear of equipment.

Recommended tyre size or powder specification

We recommend that waste tyres be processed into rubber powder or fine chips that meet the following specifications before entering the continuous pyrolysis plant: 1. Particle size: 3–10 mm (rubber powder) or 5–20 mm (fine chips); 2. Impurity requirements: steel wire removal rate ≥99%, fiber removal rate ≥98%, moisture content ≤5%; 3. Uniformity: the particle size deviation of raw materials should not exceed ±2 mm to ensure stable feeding and uniform pyrolysis.

Why size consistency matters for continuous feeding

Size consistency of raw materials is the key to ensuring the stable operation of the continuous feeding system and pyrolysis reaction: 1. Ensuring smooth feeding: Uniform particle size raw materials can pass through the screw feeder stably, avoiding blockages caused by large particles or gaps caused by small particles; 2. Maintaining sealed environment: The continuous reactor relies on the mutual extrusion of raw materials to form a “material seal” while feeding, which prevents pyrolysis gas from leaking. Uneven particle size will destroy the material seal, leading to gas leakage and safety risks; 3. Guaranteeing uniform pyrolysis: Raw materials of the same size have the same heating area and heat absorption rate, which ensures that the pyrolysis reaction is complete and consistent, avoiding over-pyrolysis or under-pyrolysis of local raw materials and improving product quality and yield stability; 4. Reducing equipment wear: Uniform raw materials can reduce the local wear of the feeder and reactor, extending the service life of equipment.

Features of Continuous Pyrolysis Plant

How Does a Continuous Tyre Pyrolysis Plant Work?

The working process of the continuous tyre pyrolysis plant is a fully automated, closed-loop system, which is divided into 6 core steps. Each step is equipped with professional technical designs to ensure high efficiency, safety, and environmental protection:

  • Pre-treatment (shredding & grinding): Waste tyres are first shredded into 5–20 mm chips by a tyre shredder, then steel wires and fibers are separated by a magnetic separator and air separator, and finally ground into 3–10 mm rubber powder by a grinder; the pre-treatment system is equipped with a particle size detector to ensure that the raw materials meet the feeding requirements.
  • Continuous feeding system: Qualified rubber powder is continuously transported to the reactor through a double-screw feeder; the feeder adopts variable frequency speed regulation technology, which can adjust the feeding speed according to the reaction status of the reactor, and forms a reliable material seal to prevent pyrolysis gas leakage.
  • Pyrolysis reactor: The rubber powder enters the horizontal continuous reactor, which is heated to 450–650℃ by recycled syngas; the reactor adopts a jacketed heating design and a rotating stirring structure to ensure uniform heating of raw materials, and the inner wall is made of 316L stainless steel to resist high temperature and corrosion.
  • Condensation & oil collection: Pyrolysis gas generated by the reaction enters a multi-stage condenser (water-cooled + air-cooled) for cooling and condensation; the condenser adopts an innovative baffle design to extend the cooling time of the gas, with a condensation efficiency of ≥95%, converting liquid hydrocarbons into pyrolysis oil which is then collected in a dedicated storage tank.
  • Continuous carbon black discharge: Solid carbon black generated after pyrolysis is continuously discharged from the end of the reactor through a sealed discharge device; the discharge device is synchronized with the feeding speed to maintain the stable pressure inside the reactor, and the discharged carbon black is cooled by a water-cooled conveyor and then collected.
  • Gas recycling & combustion: Non-condensable syngas (methane, propane, etc.) separated by the condenser is purified by a tar removal device and then recycled to the reactor’s heating system as fuel; the system is equipped with a gas storage buffer tank to ensure stable fuel supply, reducing external fuel consumption by 30–40%.

Output, Oil Yield & Operating Capacity

For large-scale waste tyre recycling investors, the core advantage of continuous tyre pyrolysis plants lies in the structural advantages of stable output, efficient operation, and low comprehensive cost—not just absolute profit figures. The key indicators are as follows:

  • Stable output & oil yield: The continuous tyre pyrolysis plant has a stable daily output of 30–100 t/day (customizable according to needs), and the oil yield of waste tyres is stably maintained at 40–45% (based on 3–10 mm rubber powder). The fluctuation of oil yield is within ±2%, and the quality of pyrolysis oil (calorific value, viscosity) is consistent. This stable output performance ensures that users can sign long-term supply contracts with downstream enterprises, avoiding losses caused by unstable output and quality.
  • Unit labor advantage: The fully automated continuous system significantly reduces labor costs. Taking a 50 t/day continuous plant as an example, only 3–5 people are needed per shift to complete the entire production process (including monitoring and simple maintenance). Compared with a batch plant of the same scale (which requires 8–12 people per shift), the annual labor cost can be saved by 60–80%.
  • Unit time efficiency advantage: The plant can operate 24 hours a day, 330 days a year (excluding maintenance time), with an annual operating time of up to 7920 hours. In contrast, batch plants have an annual operating time of only 4000–5000 hours due to frequent shutdowns. The high operating time density enables continuous plants to recover investment faster—usually the investment recovery period is 12–18 months, which is 6–12 months shorter than that of batch plants of the same scale.
  • Energy efficiency advantage: The recycled syngas can meet 30–40% of the plant’s heating demand, and the continuous heating mode of the reactor has higher thermal efficiency (≥85%) than the intermittent heating mode of batch plants (≤70%). This reduces the unit energy consumption of processing per ton of waste tyres by 25–35%, further reducing the comprehensive operating cost.

    Part 4: FAQ about Continuous Tyre Pyrolysis Plant

    Yes, tire pyrolysis can help reduce environmental pollution in several ways:

    Reduces waste tires in landfills

    Millions of waste tires are dumped or burned every year. Pyrolysis converts them into useful resources (oil, carbon black, steel wire), significantly reducing landfill pressure.

    Prevents open burning of tires

    Burning tires releases toxic smoke and harmful gases. Pyrolysis operates in an oxygen-free environment, preventing combustion and reducing toxic emissions.

    Converts waste into valuable resources
    • Pyrolysis oil → industrial fuel

    • Carbon black → rubber products, inks

    • Steel wire → recycled metal
      This reduces the demand for fossil fuels and raw materials.

    Low emissions with proper treatment

    Modern continuous pyrolysis plants include:

    • Gas purification systems

    • Dust filters

    • Smoke treatment units
      These ensure emissions meet environmental standards.

    Utilizes non-condensable gas as energy

    The non-condensable gas produced can be used to heat the reactor, reducing external fuel consumption and lowering the carbon footprint.

    Several key factors influence both the quality and market price of tire pyrolysis oil:

    Quality of the Feedstock (Waste Tires)
    • Different rubber compositions produce different oil yields and quality.

    • Cleaner, more uniform tires result in better oil quality.

    Sulfur Content
    • Higher sulfur = lower quality and lower price.

    • Low-sulfur pyrolysis oil is more valuable because it burns cleaner and meets more environmental regulations.

    Processing Technology
    • Continuous plants with stable temperatures produce more consistent, higher-quality oil.

    • Better condensation and purification systems improve oil stability and color.

    Reactor Temperature
    • Too low → low oil yield, heavy oil.

    • Too high → more gas, lighter oil.

    • A stable 420–480°C generally gives good results.

    Oil Purification and Filtration
    • Removing impurities (water, solids, carbon particles) increases oil value.

    • Filtered and dewatered oil sells at a higher price.

    Local Market Demand
    • Countries with high fuel costs or limited refinery capacity pay more for pyrolysis oil.

    • Industrial demand (asphalt plants, boilers, cement factories) also affects price.

    Legal and Environmental Regulations
    • Regions requiring low-emission fuels may limit or tax high-sulfur oils, affecting pricing.

    • Certified or tested oil often sells at a premium.

    How Tyre Pyrolysis Oil Is Produced

    Tyre pyrolysis oil is obtained through a process called pyrolysis, where shredded or whole waste tires are heated in an oxygen-free reactor. The steps include:

    1. Feeding the waste tires into a sealed pyrolysis reactor.

    2. Heating the reactor to 420–480°C without oxygen.

    3. Thermal decomposition breaks rubber molecules into oil vapor, gas, carbon black, and steel.

    4. Condensation of oil vapors into liquid pyrolysis oil.

    5. Collection of non-condensable gas (used as fuel), carbon black, and steel wire.

    The result is a dark, energy-rich oil with properties similar to heavy fuel oil.

    Pyrolysis oil is widely used as industrial boiler fuel, in asphalt and cement plants, and as feedstock for refining into diesel-grade fuel. Carbon black can be reprocessed for rubber manufacturing or activated carbon production, while steel wire is sold directly as scrap metal.

    A continuous tyre pyrolysis plant offers strong economics: raw material costs are low (waste tires are often free or paid-for via tipping fees), and the plant produces multiple sellable outputs — pyrolysis oil, carbon black, and steel wire. Syngas recycling reduces fuel costs by 30–40%, and the fully automated system requires only 2–3 operators per shift. For a 30T/day plant, ROI is typically 12–18 months under normal market conditions.
