The three directives on titanium dioxide production (78/176/EEC, 82/883/EEC, 92/112/EEC) determine the protection of in particular the aquatic environment, waste prevention and recycling and the re-use of waste as raw materials as their main goals.
By the provisions of Directive 78/176/EEC, any discharge, dumping, storage, accumulation or injection of waste will require prior authorization, for a limited but renewable period, by the competent Member State authority:
from whose territory the waste is discharged or dumped.
Directive 82/883/EEC requires Member States to carry out surveillance and monitoring of the environments affected, special account being taken of local environmental factors and the manner of disposal of the waste in question. Moreover, detailed descriptions of the sampling procedure and the sampling methods used are established.
Directive 92/112/EEC applies to solid waste, strong acid waste, weak acid waste, neutralized waste, treatment waste and dust. The processes covered are the sulphate process and the chloride process. The Directive also concerns dumping. The dumping of any waste from ships or aircraft was prohibited as of 15 June 1993.
Discharges into territorial waters and the high sea of solid waste and strong acid waste from existing industrial establishments using either process and of treatment waste from existing industrial establishments using the sulphate process are prohibited from 15 June 1993.
Discharges into any waters of waste other than territorial waters and the high sea is reduced to limit values laid down by the Directive.
