More than 1 billion discarded tires are produced globally every year, and the recycling and reuse of white carbon black has long been a pain point in the industry. The supercritical fluid depolymerization technology pioneered by XX enterprise can efficiently separate rubber, carbon black, and white carbon black from waste tires within 15 minutes. The purity of recycled white carbon black exceeds 99%, and the surface hydroxyl content is controllable, which can be directly used for high-end tire production. More importantly, this process can reduce carbon emissions by 1.2 tons for every 1 ton of waste tire processed, and recover 0.4 tons of steel wire and 0.3 tons of petroleum based chemicals. In 2025, the world's first tire circular economy industrial park will be established in Shandong, with an annual processing capacity of 500000 tons of waste tires, marking the official entry of white carbon black into the closed-loop era of "resources products renewable resources".
