Titanium Dioxide Industry Recovery Drives By-product Value Upgrading

2026/05/09


Titanos Ferrous Sulfate Heptahydrate Opens a New Track for Green Applications

Since 2026, the domestic titanium dioxide industry has recovered cyclically, with a steady upward price center and strong industrial chain synergy. As main products rebound, the value of its by-product ferrous sulfate heptahydrate has been reactivated. Shanghai Titanos Industry Co., Ltd. has become a reliable supplier for downstream sectors via high-quality products and full-chain services, boosting the industry’s green circular development.

Industry Recovery Brings High-value Opportunities for By-products

As the supply-demand pattern of the domestic titanium dioxide market continues to improve, leading enterprises are accelerating the high-value utilization of by-products while focusing on cost reduction and efficiency improvement.

As a core by-product of sulfate-process titanium dioxide production, ferrous sulfate heptahydrate has transformed from traditional industrial waste into an essential chemical raw material with both environmental and economic value. Driven by the rapid growth of downstream demand in fields like environmental water treatment and new energy, its market space continues to expand, becoming a key part of the "main products + by-products" dual-driving development model in the titanium dioxide industrial chain.
