Reducing emissions, energy and water consumption.

Case
Study 1: Treated water usage in metal smelter
Context
A number of prolonged dry summers created the need
for a major metal smelter to substantially reduce water consumption
if the smelter was to remain open. In prior years the operation
had only just escaped a major slow down of operations due
to lack of water. In addition, there was considerable pressure
for cost reduction on the site.
Approach
Our team set to work, helping management to generate ideas,
implement short interval controls and new management practices.
Results
The process yielded dramatic results – 48% reduction
in water cost and approximately 35% reduction in water usage
(see Chart 1). Moreover, this approach was also successfully
applied in other areas of the business with similar results
- reducing acid leaks by 30%
