to 30,000 tonnes/y of TiO2 pigment atits Thann plant in eastern France.Waste acid neutralisation had beencarried out for many years at theThann sulfate-route TiO2 pigmentplant site, even before MillenniumChemicals took over running theoperation. However, the 140,000tonnes/y of solid crude gypsumproduced by acid neutralisation wassimply dumped at an approval landfillsite. Millennium has now completed aprogramme to convert the crudegypsum waste into a marketable whitegypsum product. Onwards from thebeginning of 2003, the company hasbeen selling 50,000 tonnes/y of thiswhite gypsum to cement and buildingplaster manufacturers. Meanwhile, itcontinues to generate about 90,000tonnes/y of red gypsum at Thann: thismaterial is currently being used for“landscaping” at the company’s wastedisposal site in Ochsenfeld.Millennium is investing €50 M forlandscaping and protection of thewater table at Ochsenfeld. When thecompany ceases landscaping atOchsenfeld in 2008, it will be obligedto find new outlets for marketing ordisposing of the red gypsum.
