Abstract
Methods of remediating construction and demolition waste by collecting sulfur containing construction and demolition waste materials, adding a sulfur stabilizing agent to the construction and waste materials, admixing the sulfur containing construction and demolition waste materials and the sulfur stabilizing agent to form a sulfur stabilized construction and demolition waste material.
Claims25
A method of remediating construction and demolition waste comprising the steps of:
- Collecting sulfur containing construction and demolition waste materials;
- adding a sulfur stabilizing agent to the construction and waste materials;
- and
- admixing the sulfur containing construction and demolition waste materials and the sulfur stabilizing agent to form sulfur stabilized construction and demolition waste material.
The method of claim 4 wherein the metal of the sulfur stabilizing agent is iron, calcium or mixtures thereof.
A method of remediating construction and demolition waste comprising the steps of:
- collecting sulfur containing construction and demolition waste materials;
- reducing the particle size of the sulfur containing construction and demolition waste materials to an average particle size of from about 0.1 mm to about 2 inches;
- adding hydrated lime to the size reduced construction and waste materials;
- admixing the size reduced sulfur containing construction and demolition waste materials and the hydrated lime in an amount ranging from about 25 lbs. per ton to about 45 lbs. per ton to form a sulfur stabilized construction and demolition waste material;
- and
- using the sulfur stabilized construction and demolition waste material in a landfill application.
A municipal solid waste landfill comprising:
- a plurality of municipal solid waste layers;
- and
- a layer of daily cover material separating at least two of the plurality of municipal solid waste layers wherein the daily cover material is an admixture of at least one sulfur stabilizing agent and sulfur containing construction and demolition fines.
