Tronox Holdings plc the world’s leading integrated manufacturer of titanium dioxide (TiO2) pigment, announced that as a result of a strategic review of its asset footprint, Tronox has informed its Netherlands’ labor force that it intends to idle its 90,000 metric ton per year TiO2 plant in Botlek, the Netherlands. The site is currently shut-down due to an outage by the site’s chlorine supplier that began on March 6, 2025, but upon conclusion of consultation with the works council, is not expected to be brought back online. Tronox expects this action will not impact its ability to serve customers, as the Company will leverage its diverse footprint to provide uninterrupted supply. The operating site currently employs approximately 240 impacted permanent staff. John D. Romano, Chief Executive Officer, commented, “Our announcement today is the result of an extensive review of our asset footprint driven by the ongoing global supply imbalance caused by Chinese competition as well as an increasingly challenged operating environment over the last two and a half years. Idling our Botlek facility enables the optimization of our remaining facilities and improves our overall manufacturing costs. Our Botlek colleagues are an important part of our Tronox team. We are committed to assisting employees during this difficult time and will be providing support by local management and a comprehensive range of services.”

After much consideration, Nekoosa has chosen to discontinue and exit our DIGITAL COATED paper offering at the end of 2020 and we will be selling off our existing inventory without replenishment. The decision to exit this lane was not an easy one, but at the end of the day we do feel it’s best for our business. We are operating on a “while supplies last” basis for this product line and customer service can let you know our current stock levels and pricing for the SKUs that you typically buy. The reasons for this decision can be summarized as a combination of things such as: supply chain issues, an interest in freeing up converting equipment to focus on other product segments, and profitability of the line.
