Abstract
Titanium dioxide is the most used white pigment worldwide. The production takes place in two stages. The first step, an upgrading-process, increases the TiO2 content in the feedstock, the ilmenite. This is followed by the pigment production treatment, either by the sulfate or the chloride technology. Both variants cause a high amount of landfill waste and lead to a major environmental impact. This paper investigates the integration of waste and byproducts from the chloride route in the upgrading-process. Afterwards, a comparison between the combined process and the conventional pigment production route is made. Due to the recycling, landfill waste and operational costs decrease. At the same time, the economic results can be improved. A review of the market situation shows that the combined method is a possibility for new investments.
