Waste Management and Beneficial Reuse

Many foundries are already involved in waste management and beneficial reuse programs in their respective states. These beneficial reuse programs promote the reuse of foundry by-products in lieu of landfill disposal. Beneficial reuse of such materials such as foundry sands and slags preserves landfill space, conserves natural resources, reduces CO2 emissions, strengthens local economies and saves money. Substantial savings may be derived from converting a hazardous waste stream into either a non-hazardous waste or a beneficial reuse material with a slight change to the process or raw materials used in the process.

AFS has a specific webpage for Beneficial Reuse (make sure to check it out).

A beneficial use program identifies appropriate alternative uses for foundry byproducts to replace or supplement a raw material or competing product (like roadway construction material, cover, mulch mixture, etc.).
