:: Wagerup Emissions May Cause Cutback  

Alcoa World Alumina and Chemicals (AWAC), 60%-owned by Alcoa Inc. and 40% by WMC Ltd, may be forced to reduce output to meet stricter environmental regulations at its Wagerup alumina refinery in Western Australia. The state's environmental authorities have ordered AWAC to reduce nitrogen oxide (NOx) and odour emissions by June 30, or cut back on production by 150,000 t/y (6% of capacity). An AWAC spokesman has expressed confidence that the emissions will be reduced as required, but conceded that production cutbacks remain a possibility.

The emissions are caused by the liquor-burning unit at Wagerup, which destroys organic material in the bauxite being processed.
