Vale Project Will Reduce Sudbury Smelter Emissions
Vale has approved a $2-billion investment
to reduce sulphur dioxide emissions at its
smelter in Sudbury, Ontario, by 70% from
current levels. Vale has already invested
heavily in the “Clean AER Project,” spend-ing some $100-million on research and
development over the past four years in
preparation for final project approval.
Clean AER (AER stands for atmospheric
emissions reduction) is in addition to the
90% reduction in sulphur dioxide emis-sions realized at Sudbury since 1970 and
complements the ongoing “re-greening” of
the Sudbury region.
The 70% reduction will bring sulphur
dioxide emissions at Vale’s Sudbury opera-tions down to 45,000 mt/y, below govern-ment regulated emissions limits of 66,000
mt/y. The project will also reduce emis-sions of dust and metals by 35% to 40%
from current levels.
Vale estimates the retrofit will require
about 8-million person-hours of additional
labor, with 1,300 workers on-site during
Construction will begin with site prepa-ration activities in April. Project comple-tion is estimated near the end of 2015.
