Ahead of this year's Recovered Carbon Black Asia 2025, we spoke with Yunchao Hu, R&D Engineer at Doright Co., Ltd., to get a sneak peek of what we can expect from his presentation on 'Recovered Carbon Black Pelletizering System' Here's what he had to say…




Q1. Your talk at the Recovered Carbon Black Asia 2025 will dive into Recovered carbon Black Pelletizering System. Why do you think it’s important for others in the industry to hear this message?

At present, in many regions, recycled carbon black (rCB) is still sold at a low price as pyrolysis residue. The rCB granulation system innovatively launched by Doright not only significantly increases the added value of rCB but also effectively reduces transportation and storage costs, creating higher economic benefits for tire pyrolysis enterprises.


Q2. Can you give us an update on what's happening in your local market? What are the latest trends over there?

Currently, the Chinese tire pyrolysis industry is undergoing a significant transformation, with an increasing number of enterprises shifting their strategic focus from the production of pyrolysis oil to the development of high-quality recycled carbon black (rCB). Meanwhile, many primary carbon black producers are also actively entering the rCB sector, exploring the potential of this emerging market.


Q3. Which challenges and opportunities do you see for the recovered carbon black industry in your local market?

Although the rCB industry is still plagued by quality issues (such as oil film residue and high ash content), which restrict its ability to replace raw carbon black, the 'dual carbon' policy has injected new impetus into this industry. The rCB with environmental-friendly characteristics has a considerable market potential in the future.


Q4. Looking ahead, what do you think will be some exciting developments in recovered carbon black or tire pyrolysis soon?

With the continuous improvement of the industry ecosystem and the addition of more professional forces, the tire pyrolysis and rCB industries are entering a new stage of high-quality development. Driven by the dual forces of technological innovation and industrial collaboration, the existing technical bottlenecks are expected to be overcome, and the development prospects of the industry continue to improve.


Q5. What hurdles does the tire pyrolysis value chain need to tackle in the next few years?

At present, it is urgent to break through the technical bottleneck of continuous production of cracking equipment, and focus on solving key problems such as insufficient sealing performance and severe coking. At the same time, efforts should be made to optimize the cracking process of tires, and develop more economically and highly efficient post-processing technology solutions for rCB.


Q6. Are there any specific collaborations within or with the value chain that you're looking for?

Doright will continue to deepen its technological innovation in the rCB post-processing system, and sincerely invites industry experts and scholars to jointly discuss and promote development. At the same time, we warmly welcome manufacturers interested in rCB granulation technology to carry out in-depth cooperation, and jointly promote industrial upgrading.
