One of the key aspects of a modern white titanium dioxide factory is its commitment to sustainable practices. Factories are increasingly adopting eco-friendly technologies to minimize waste generation and reduce energy consumption. For instance, some factories utilize waste heat recovery systems to harness and reuse heat generated during production, significantly cutting down on energy costs and carbon emissions. Additionally, advanced filtration systems ensure that any byproducts are treated and disposed of responsibly, adhering to strict environmental regulations.

Zinc oxide. Zinc oxide is a popular cross-linking agent for rubber and for various resins. It is essential in the formulation of solvent-borne polychloroprene adhesives. Furthermore, zinc oxide is a good UV stabilizer, has biocidal activity and has a relatively high refractive index (2.0) which makes it an efficient white pigment. Some typical properties are: density 5.6 g/cm3; particle size 0.036-3 μm; oil absorption 10–20 g/100 g; specific surface area 10–45 m2/g. Zinc oxide is produced by reaction of the metal in the vapour state with oxygen. Zinc oxide is nonporous and is quite pure. Thus, the high surface area of some grades is due to the small particle size of zinc oxide. Some grades, especially for use in the rubber industry, are surface modified by deposition of 0.2-0.4% of stearic acid, propionic acid, or light oil [47].

The primary function of Anatase Titanium Dioxide in food is as a coloring agent. Its intense whiteness can effectively brighten and whiten foods such as powdered sugar, confectionery, and dairy products. By adding small amounts of this compound, manufacturers can achieve a more visually appealing product that attracts consumers. Moreover, its high refractive index means that it can be used to add a glossy finish to certain foods, further enhancing their appeal.

In the realm of pigments, titanium dioxide's ability to reflect light across the visible spectrum makes it an ideal candidate for brightening products. It is widely used in paints, plastics, paper, inks, food coloring, and cosmetics. The addition of TiO2 not only enhances the whiteness but also improves the durability and opacity of these materials. Moreover, its non-toxic nature ensures that it can be safely used in products that come into direct contact with humans, such as food colorants and cosmetics.

Food containing titanium dioxide that is lawfully placed on the EU market before 7 August 2022 may remain on the market until its date of minimum durability or its ‘use-by’ date has passed. Food produced or placed on the market after 7 August 2022 cannot contain titanium dioxide. The ban on the use of titanium dioxide is effective in each EU Member State, and in Northern Ireland. Some third countries, such as the United Kingdom (excluding Northern Ireland), continue to permit the use of titanium dioxide.
