DOING Secures Order for 6 Units of Batch Tire Pyrolysis and 2 Units of Waste Oil Refining Machine from Saudi Client

In December 2025, DOING Company, a manufacturer of pyrolysis machines and waste oil refining equipment based in China, signed a contract with a tire shredding and export business from Kingdom of Saudi Arabia (KSA). The order includes six 15-ton batch tire pyrolysis machines and two 15-ton solid catalyst tire pyrolysis oil refining machines. This Saudi Arabian client has many years of experience in the tire processing industry and a clear understanding of market demand. This expansion into fuel oil production and sales aims to further integrate the industrial chain.

Waste tire to diesel process

The core of the Saudi client's decision-making process was a comprehensive evaluation of fuel oil production technology. The client prioritized equipment reliability, practical design, and ease of operation, and conducted detailed evaluations of multiple suppliers. They focused on how each solution handled the entire process from tire input to refined diesel output, especially considering their existing waste tyre cutting shredding systems.

Technical Evaluation and DOING's Solution

Project Matching: Because the Saudi customer required higher-quality, more versatile non-standard diesel fuel, rather than pyrolysis oil similar to heavy fuel oil, DOING's engineering team translated the Saudi client's core needs into a two-stage solution that integrates tire pyrolysis machines and tire pyrolysis oil solid catalytic refining machines. Key design choices include the sealing mechanism and uniform heating distribution of the pyrolysis reactor, which prevent leaks and ensure uniform tire pyrolysis treatment. For the pyrolysis oil refining machine, DOING provided the Saudi client with a detailed explanation of the distillation tower configuration using DOING's patented catalyst. This configuration utilizes DOING's independently designed catalyst materials and corrosion-resistant equipment materials to ensure stable operation of the pyrolysis oil refining process. This solution ensures cost-effective and stable production even with fluctuations in the client's tire raw material quality.

DOING Machine Technology Highlights

Batch Tire Pyrolysis Machine:

1. Operating in batch mode, it offers significant advantages in waste treatment, primarily due to its high flexibility and ease of operation. Users can adjust the processing volume according to their needs, simplifying start-up and shutdown procedures and lowering the skill threshold.

2. The initial investment is relatively low. The relatively simple design results in more economical manufacturing and installation costs, making it an ideal choice for pilot projects or companies with limited budgets.

3. Maintenance and troubleshooting are also more convenient. The independent batch process does not affect overall production, facilitating maintenance, and the simple structure is easy to maintain.

Solid Catalyst Tire Pyrolysis Oil Refining Machine: Its core advantage lies in the solid catalyst mechanism. Compared to traditional waste oil refining machines that rely on acid-base liquid catalysts, DOING's new solid catalyst waste oil refining machine does not require frequent injection of liquid catalysts, greatly simplifying operation and reducing operating costs and labor requirements. At the same time, the catalyst has a longer lifespan and more stable reaction, precisely meeting the client's dual needs for oil quality and operational convenience.
