In response to concerns surrounding the large quantities of waste generated in the manufacture of TiO2 , legislators have framed new laws and regulations to control wastes from the industry.

Tioxide have used Life Cycle Assessment studies to gain a better understanding of the environmental issues surrounding the manufacture of TiO2 from the extraction of titanium bearing ores and other raw materials, to the production of the final pigment.

The results show that, from an environmental standpoint, the optimum operation at any particular location is determined by a balance of factors, including type of titanium feedstock, availability of sulphuric acid and chlorine supplies, local environmental sensitivities and marketing opportunities for co-products.

LCA studies form part of Tioxide’s environmental strategy which is based on Assessments, Investment and Communication. Environmental pressures show no sign of abating and industry must review its approach to this subject. The most enduring and cost effective solutions will be those formulated around the whole product chain and to this end it is important that all parties become involved in the dialogue. Also, industry must address the legitimate concerns of the public by adopting a policy of openness and publication of information.
