When the calcium carbonate reforms it captures and adsorbs many of the impurities in the juice and precipitates out from the juice. The precipitate forms a solid lime product that needs to be discarded, leaving behind the thin juice from which sugar is extracted.

The U. S. sugar cane industry is located in the tropical and subtropical regions of Florida, Texas, Louisiana, Hawaii, and Puerto Rico. Except for Hawaii, where sugar cane production takes place year round, sugar mills operate seasonally from 2 to 5 months per year. Sugar cane is a large grass with a bamboo-like stalk that grows 8 to 15 feet tall.

The calcium carbonate (30%, w/w) decreased 40–60% of sugar yield of unbleached softwood kraft pulp. The prime mechanisms for this are by pH variation, competitive and non-productive binding, and aggregation effect. Addition of acetic acid (pH adjustment) increased the sugar production from 19 to 22 g/L of paper mill waste fibers.

Lime is used to capture and remove impurities in the juice of sugar beets. 125kg of limestone are used for the production of one ton of sugar. Most sugar-processing plants have their own lime kilns, so they need good-quality limestone to burn. The high calcium limestone is converted into quicklime in these lime kilns, at a temperature of 900°C.
