Ahead of this year's Recovered Carbon Black Asia 2025, we spoke with Wachirawit Chailangka, QC/QA/R&D Manager at PYRO Energy to get a sneak peek of what they expect from the conference.
Q1. What are you most looking forward to at Recovered Carbon Black Asia this year? I am looking forward to seeing tire manufacturers make progress on the feasibility of reusing products derived from pyrolysis process.
Q2. Can you give us an update on what's happening in your local market? What are the latest trends over there?
In fact, Thailand already has several pyrolysis plants for rubber. Currently, the domestic market is primarily focused on selling the output as fuel, and no company has yet developed value-added products from it.
Q3. Which challenges and opportunities do you see for the recovered carbon black industry in your local market?
Of course, we see the potential in developing char into recovered carbon black (rCB), but I believe there are still limitations in terms of purity. Therefore, our company is proposing an alternative approach: producing sustainable carbon black (sCB) from distilled pyrolysis oil, which currently offers a higher level of purity and represents a better solution.
Q4. Looking ahead, what do you think will be some exciting developments in recovered carbon black or tire pyrolysis soon?
I would like to have clarity from end users (tire manufacturers) on whether rCB needs to be adjusted in terms of ash content, treated for Zn and Si, or if that’s not necessary. Do they have a specification? When do they plan to use it? And at what blending ratio?
Q5. What hurdles does the tire pyrolysis value chain need to tackle in the next few years?
Of course, it all comes down to competition in terms of tire waste collection, technology development, product quality, and marketing.
Q6. Are there any specific collaborations within or with the value chain that you're looking for?
I'm looking for a partner to help develop char (rCB) into a material that can be practically used in the tire industry.
