Traditionally, farmers use ground calcitic limestone (CaCO 3) or dolomitic limestone (MgCO 3 CaCO 3) to reduce soil acidity. Some farmers may have the opportunity to use byproducts of municipal water softening, or sugar beet processing to lime their soils. Growers can use these materials effectively to raise soil pH.

The coupled use of calcined clay and ground limestone has been a promising alternative to partially replace Portland cement due to the synergic effects between these two additions. Therefore, substituting calcined clay with a material of similar chemical composition, such as water treatment plant sludge ash (WTPSA), yields several environmental advantages.

The use of lime generates significant amounts of sludge in wastewater collections and treatment. On a chemical basis, one ton of lime can generate as much as 11.5 to 15.5 tons of 20 percent sludge cake to remove or dispose. In contrast, Thioguard reactions in wastewater produce only water and water-soluble products as TDS with no added sludge.

Lime and heat treatment are the most common techniques. Lime or some lime-containing waste material may be added to sludge, with the aim of maintaining a pH of 12 or above for 2 h, with residual pH above 11 for a few days. This may be undertaken before or after dewatering. It is not a permanent solution, and does not kill all organisms present.
