North Star Steel completed a plant-wide energy assessment designed to examine potential process changes and technologies that could improve energy efficiency in its plant in Wilton, Iowa. The assessment team performed a Total Assessment Audit to evaluate the plant's focus areas for energy savings, waste reduction, and improved productivity. The assessment techniques, data gathered during the assessment, and technical solution options will be shared with North Star Steel's other mini-mills where similar evaluations and energy/waste reduction improvement projects can be employed. If all projects identified during the Wilton plant study were implemented, the assessment team estimated that total annual energy savings would be about 140,000 MMBtu in natural gas and nearly 39 million kWh in electricity. Total annual cost savings would be more than $2.6 million.
