It has been known since 1998 that the processing of titanium via chloride route generates persistent organic pollutants like dioxin, furan, poly chlorinated biphenyls etc. The inventory of toixins also includes heavy metals and polycyclic aromatic hydrocarbons, most of which are carcinogenic and mutagenic. Costly remedial measures have been implemented by the industry in Europe, North America and Japan during the last decade. Prices of titanium products more than doubled due to this. However, it has been business as usual in the Kerala Minerals and Metals Ltd, a public sector undertaking and the only producer of titanium dioxide pigment via chloride routein India. With about half a million tons of solid waste containing highly hazardous substances, which will stay in the eco-system, the biosphere and the breast milk for hundreds of years into the future, the industry is neck deep in crisis.
