The proposal is to increase the production capacity of Tiwest's titanium dioxide plant at Kwinana. The proposal is to modify/expand the existing plant to allow an increase in production capacity from 80,000 tonne per annum (tpa) to 180,00 tpa of titanium dioxide pigment in three notional stages:
- Stage I: increase to 120,000 tpa,
- Stage 2: increase to 165,000 tpa and
- Stage 3: increase to nominally 180,000 tpa.
The first and second stages of the expansion wilI require major modifications to the plant (plant infrastructure to achieve 180,000 tpa capacity will be developed during Stage 1 construction and approximately 85% of the mechanical process equipment will be installed in Stage 1). Stage 3 expansion will depend upon technological and commercial viabilities and will require minor modifications.
