In recent years, China has seen a rapid growth in chemical industry but manufacturers and governors have long been bothered by consequent heavy pollution.
A leading titanium dioxide manufacturer, based in Southwest China''s Sichuan province, got involved in water pollution scandal last month, arousing heated discussion.
Actually, the majority of Chinese titanium dioxide is produced by sulfuric acid process, which has greater damage on environment and require higher sewage disposal cost than that of chlorination process.
Policies on green production are under development to improve present situation, and iron oxide industry is the first one affected. In Handan city of Hebei province, three small ferrite yellow factories were forced by environmental protection bureau to stop production temporarily because of heavy water pollution.
For long time, iron oxide industry stays on environmental protection bureau''s blacklist for high energy consumption and severe pollution, and it is believed that one of the ways to solve the problem is reducing waste amount through technological reformation.
Generally speaking, chemical industry is not that environmental-friendly, but different products can cause damage of different extent on the environment. In high polluting industries such as coatings, dyestuff and paints industry, heavy pollution even prevent companies from going public.
