Reducing emissions, energy and water consumption.

Case 3: Blast furnace emissions
Context
Our client’s blast furnace had high levels of emissions
that were causing concern for the company, employees and nearby
residents. Emissions were being caused by highly variable,
sub-optimal operating conditions.
Approach
Once the team had determined the major drivers of emissions,
it focused on:
- Managing the causes and consequences of feed variability
- Operating procedures, coaching and management disciplines
to lock in the new procedures and ensure consistent practices
between operators and across shifts.
Results
Emissions, much like waste, are inversely correlated with
the stability of a production process. Improved control led
to a 75% reduction in emissions and a 25% increase in the
daily production rate.
At a third smelter on a different site, the team systematically
determined the root causes of emissions and delivered a 50%
reduction in emissions, and increased production by 34%.
