Abstract
A lime kiln is a stationary piece of machinery that converts calcium carbonate into calcium oxide by heat. It is usually operated in a continuous manner rather than a batch system. These systems are used across multiple industries, but are most common in cement production, fertilizer manufacturing, and in pulp and paper processing. In 2014, Sappi Cloquet LLC commissioned a Lean Six Sigma project around the lime kiln to increase throughput and uptime. This report contains a comprehensive report of the project, as well as the background for its justification. Over a one year period, the project saved Sappi an estimated $2MM.
