DOING Signed Contract With Colombian customer for 500kg Fabricated Pyrolysis Machine and Pyrolysis Oil Refinery Machine

In January 2026, DOING Company, a manufacturer of pyrolysis and waste oil refining equipment, signed a contract with a Colombian customer to provide them with a 500 kg fabricated pyrolysis machine and a 500 kg fabricated pyrolysis oil refinery machine. These two pieces of equipment are designed to convert plastic waste into usable fuel oil for the client's plastic recycling project.

The customer works for a medical waste sorting and recycling company in Colombia. After learning about plastic pyrolysis technology, the company wanted to launch a project to extract fuel oil from plastic materials. During negotiations, the customer's company abandoned this plastic recycling fuel oil project, but the customer did not give up and decided to pursue the project independently. During the contract signing process, the customer emphasized that equipment quality was the primary consideration and carefully examined aspects such as the durability of DOING's equipment materials, processing efficiency, and long-term reliability as well as the strength of DOING Company itself.

DOING Company is a professional manufacturer of pyrolysis machines and waste oil refinery machines with over ten years of experience in equipment manufacturing. The company has a large production base in China, equipped with customized assembly and quality testing facilities. DOING Company has provided projects to over 100 countries and regions worldwide, including similar waste to fuel oil applications installed in South Africa, India, Chile, Mexico, Venezuela, the United States, Romania, Egypt, and other regions. These projects involve equipment for processing various waste plastics and waste tires, and have demonstrated stable performance in actual operation.

To meet the Colombian customer's requirements for equipment quality, DOING provided detailed process documentation, including flowcharts for the pyrolysis and refining stages, as well as detailed equipment information, and comprehensive after-sales support.

The 500 kg fabricated pyrolysis machine provided to the customer features a robust structure and uses high-pressure resistant materials. Key components are welded using precision welding techniques to minimize leaks, and a multi-layer thermal insulation design maintains a stable temperature during the pyrolysis process. The machine's core components, such as the condensing coils, are made of corrosion-resistant alloy materials to withstand the acidic byproducts produced during plastic decomposition. The unit can achieve an oil yield of approximately 40-50% from mixed plastics and is equipped with integrated safety valves and pressure sensors to ensure reliable operation. Furthermore, the 500 kg fabricated pyrolysis oil refinery machine utilizes a catalytic-efficient distillation system, ensuring reliable operation when processing pyrolysis oil. The unit includes a distillation tank and acid-base liquid catalytic filtration for removing impurities and odors. This system maintains a stable output, converting crude pyrolysis oil into clean, usable diesel fuel suitable for diesel engines, heavy machinery, or industrial boilers, with a diesel fuel conversion efficiency of 85-90%.

Advantages of DOING fabricated waste to fuel oil machine

These machines have compact structure, requiring only approximately 50 square meters of floor space, and requires no assembly. It is easy to operate, requiring no extensive technical expertise, making it ideal for private businesses. The moderate investment cost also makes it an ideal choice for small-scale waste recycling projects.

Currently, the 500 kg fabricated pyrolysis machine and 500 kg fabricated pyrolysis oil refinery machine are in production at DOING's facility, with delivery scheduled in two months. Once installed in Colombia, the machines will process plastic waste, converting it into fuel oil for the customer's initiative.
