The waste plastic pyrolysis plant is designed to thermally decompose various plastic wastes into fuel oil, carbon black, and combustible gas under an oxygen-free environment. It offers a sustainable and efficient solution for managing plastic pollution while generating valuable energy resources.
This plant is widely used in industrial and environmental sectors, providing a reliable method for converting plastic waste into alternative fuels. With its eco-friendly design and high efficiency, it supports global efforts toward resource recycling and pollution reduction.
Globally, over 400 million tons of plastic waste are generated every year, and a large portion of it is either landfilled or incinerated, causing long-term damage to the environment. Plastics are difficult to degrade and can persist for centuries. Incineration generates toxic fumes, while landfilling causes soil and water contamination.
Plastic pyrolysis offers a cleaner, more efficient way to manage plastic waste. Through high-temperature, oxygen-free decomposition, plastic waste can be converted into valuable products like pyrolysis oil and carbon black. This method not only prevents pollution but also turns waste into profit.
With no open flames, no wastewater discharge, and advanced emission control systems, plastic pyrolysis is an eco-friendly and revenue-generating solution for modern waste management.
| Plastic Type | Can Be Used for Pyrolysis? | Oil Yield | Notes |
|---|---|---|---|
| PE | ✅ Yes | 70-85% | Common in plastic bags, bottles, containers. High oil yield. |
| PP | ✅ Yes | 65-80% | Found in caps, food containers, automotive parts. Excellent oil recovery. |
| PS | ✅ Yes | 70-90% | Used in foam packaging, disposable cups. High-quality oil, but may produce more gas. |
| ABS | ⚠️ Partially | 30-50% | Can be processed, but produces more residues and may release toxic gas. Needs purification. |
| PVC | ❌ No | N/A | Releases harmful HCl gas during pyrolysis; not recommended. |
| PET | ❌ No | N/A | Low oil yield, high moisture & oxygen content; not suitable. |
Industrial Fuel
Used directly as fuel in boilers, furnaces, cement kilns, and glass factories for heat energy generation.
Power Generation
After distillation, the oil can be used in diesel generators for electricity production.
Petrochemical Refining
Can be further refined into naphtha, which serves as a feedstock for manufacturing plastics, synthetic fibers, and other chemicals.
Reprocessing
Used in pyrolysis oil upgrading units to extract chemicals such as BTX (benzene, toluene, xylene) and other valuable hydrocarbons.
We provide three pyrolysis solutions according to different production capacities and investment requirements:
| Type | Batch Pyrolysis Plant | Semi-continuous Pyrolysis Plant | Continuous Pyrolysis Plant |
| Model |  |  |  |
| Workflow | Manual/Auto feeding → Heating → Stop for cooling reactor → Discharge | Sealed feeding → Heating → Stop for cooling reactor → Discharge | Continuous feeding → Pyrolysis → Continuous discharging |
| Raw Material Pretreatment | Depends on plastic type (some need shredding) | Shredding usually required | Shredding required |
| Unit Capacity | 3-15TPD | 10-20 TPD | 20-50 TPD |
| Labor Quality | 3-6 person/shift | 1-4 person/shift | 1-3 person/shift |
| De-dusting System | Basic | Enhanced | EU-standard |
| Investment | Low | Moderate | Higher |
| Type | Pros | Cons |
|---|---|---|
| Batch | 1. Low investment cost 2. Easy maintenance 3. Suitable for small-scale production | Cannot run continuously, lower output |
| Semi-continuous | 1. Higher efficiency than batch 2. Reduces labor cost 3. More automation | Preprocessing required, limited continuous runtime |
| Continuous | 1. 24/7 uninterrupted operation 2. Fully automatic feeding and discharging 3. Most eco-friendly | Higher initial cost, higher pretreatment demand |
1. Pretreatment
Plastic materials may need drying and shredding to reach required size and moisture level.
2. Feeding
Processed plastic is automatically fed into the pyrolysis reactor via belt or screw feeders.
3. Pyrolysis
Reactor is heated to 300~450°C. Plastics decompose into oil gas. Lighter gas flows into condensers, heavier material remains for repyrolysis.
4. Condensation
Oil gas is condensed into liquid fuel and stored. Non-condensable gas is reused as heat source.
5. Emission Treatment
Exhaust is purified via a multi-layer system to meet local environmental standards.
6. Product Collection
Carbon black and solid residues are automatically collected and cooled.
Eco-Friendly
Integrated dust removal, gas purification, and zero-wastewater emission technology.
Energy Efficient
Self-sustaining system that reuses combustible gas for heating.
Automated
PLC control system supports automated operation and reduces manpower.
Durable Structure
Corrosion-resistant and heat-resistant reactor materials ensure safe, long-lasting use.
Custom Solutions
Configured for different plastic types and capacity requirements.
One-stop Support
Site planning, installation, training, and post-sale services all included.
