Properties: The Terra-Bond™ technology can be used to encapsulate hazardous, solid, finely divided waste materials within stable, discrete pellets with the following general properties:

• Durability: freeze-thaw stability and chemical resistance.
• Environmental soundness: the hazardous waste Terra-Bond™ technology utilizes primary, secondary and (if necessary) tertiary encapsulation to provide effective contaminant leachate control relative to regional environmental regulatory guidelines. A substantially different production regime is required for hazardous waste encapsulation, relative to synthetic aggregate production.
• Handling: discrete pellets are readily handled using conventional equipment making them conducive to efficient storage and movement within containment facilities.

Applications: The Terra-Bond™ process is particularly useful to de-classify finely divided, solid, hazardous wastes. The de-classified wastes, in the form of pellets, can then be safely stored in a suitable containment facility.

Suitable Contaminants and Waste Materials: laboratory testing has proven the Terra-Bond™ technology to be highly effective at encapsulating/stabilizing the following materials:

• Arsenic trioxide baghouse dust from the mining industry.
• Tailings and precipitator dusts contaminated with heavy metals.
• Soils contaminated with heavy hydrocarbons.
