Project and Process Overview

Entop Technology Co., Ltd. is leading a collaborative project focused on the development of state-of-the-art waste tire pyrolysis facilities.

This project aims to convert end-of-life tires into high-value resources, enabling the recycling of high-quality carbon black, steel wire, and synthetic gas through an advanced pyrolysis process.
 

By integrating Entop Technology’s modular pyrolysis design, we will establish an efficient and sustainable tire recycling system that aligns with ESG goals and the RE100 initiative.
 

🔹 Step 1: Supply and Receipt of Raw Materials (Waste Tires)

  • Waste tires, the primary raw material, are procured and processed into chips (20-40mm in size) before being supplied to the facility.

  • Shredding tires into chips optimizes them for pyrolysis reactors, enhancing processing efficiency.
     

🔹 Step 2: Feeding Tire Chips into the Pyrolysis Reactor

  • The processed tire chips are introduced into a continuous pyrolysis reactor with a sealed structure.

  • This closed system prevents environmental pollution while maximizing process safety and efficiency.

  • An automated continuous supply system ensures stable raw material input and optimized operation.
     

🔹 Step 3: Tire Chip Pyrolysis via Indirect Heating

  • Inside the reactor, hot air is used for indirect heating, thermally degrading the tire chips.

  • Indirect heating ensures uniform temperature distribution without direct flame exposure, increasing process stability.

  • As the temperature rises, the tire chips vaporize, initiating the full pyrolysis reaction.
     

🔹 Step 4: Production of Pyrolysis Gas and Pyrolysis Oil

  • During pyrolysis, the heated tire chips generate pyrolysis gas.

  • Cooling and condensing this gas produces pyrolysis oil, which accounts for approximately 35% of total output.

  • Uses of pyrolysis oil:

    • Alternative fuel source

    • Further refinement for commercial-grade applications
       

🔹 Step 5: Recovery of Recycled Carbon Black (rCB)

  • Recycled Carbon Black (rCB), one of the main by-products of pyrolysis, is recovered.

  • It represents approximately 42% of the total output and is widely used in tire, rubber, and plastic manufacturing.
     

Additional Processing to Enhance Utilization:

1.   Initially, rCB is in fine powder form.
2.   It is purified and processed into granules.
3.  Granulation improves handling and expands industrial applications, making it suitable for use in tire production, rubber, and plastic products.
 

🔹 Step 6: Energy Utilization via Non-Condensable Gas

  • Approximately 20% of pyrolysis gas that cannot be condensed is recycled as an energy source for the reactor.

  • This enables continuous operation without requiring external fuel, creating an eco-friendly energy solution.

  • Initial heating is powered by LNG or LPG, but once the system is running, it utilizes its own gas to reduce operating costs and environmental impact.
     

🔹 Step 7: Continuous and Automated Operation System

The entire process operates through a 24-hour automated system, offering the following advantages:

1.  Consistent performance with minimal manual intervention
2.  Increased productivity by reducing operation time
3.  Real-time monitoring and control of critical parameters, including temperature, pressure, and gas flow
 

🔹 Entop Technology’s Sustainable Waste Tire Pyrolysis System

Entop Technology’s pyrolysis process is built on a sustainable system that transforms waste tires into high-value products.

1.  Creating economic value by recycling waste into reusable resources
2.  Achieving eco-friendly operations by using by-products (non-condensable gas) as an internal energy source
3.  Enhancing energy efficiency and process reliability through advanced automation systems

With innovative technology and a commitment to sustainability, Entop Technology is leading the way in next-generation waste tire recycling solutions.
