Lime treatment has several beneficial effects on soils and industrial sludge wastes that in turn provide benefits to other commercial sectors such as agriculture, landfill operations and land development.
First, soils and sludges are dried when treated with lime, resulting in improved handling and in some cases allowing soils and sludges to gain sufficient strength to allow machinery to drive and operate on them.
Secondly, soils and sludges are chemically changed to encapsulate and precipitate metals and non-metals, while simultaneously decreasing permeability and leaching. This treatment is called solidification and stabilization and is widely used in the environmental remediation industry to stabilize hazardous and non-hazardous waste for reuse or landfill.
Lastly, animal wastes can be treated with lime products to prevent odors and kill pathogens, and to augment their value as an agricultural fertilizer. Lime products can be also be used in concentrated feeding operations to sanitize animal quarters.
