Economics of Super Absorbent Polymers & Waste Stabilization

The use of super absorbent polymer (superabsorbent polymer or SAP) in waste stabilization offers many advantages over more conventional absorbents. These advantages include:

• Minimal increase in waste volume or weight
• Lower transport fees due to less loads
• Lower total landfill disposal fees due since waste volume has not expanded
• Faster processing time and consummate labor savings
• No exothermic reaction to release organics or PCBs into the environment.
• Ability to bind most soluble Heavy Metals to prevent leaching

Conventional absorbents include lime kiln dust, Portland cement, dried corn cob, shredded newspaper, bentonite clay and saw dust. These conventional absorbents are relatively cheap – priced in the $20 to $50 per ton range. Why would someone use a super absorbent polymer that can cost $2.00/lbs or more?

The waste Project Manager needs to evaluate all the key cost parameters of the particular waste stream to determine if the use of SAP is appropriate and cost effective.

In the case of radioactive waste, where loads must be shipped long distances and landfill costs can reach $1000 per cubic yard or more, the use of super absorbent polymer to prevent volume expansion is quickly realized in cost saving. Let’s assume one pays $400 to dispose of a single 55-gallon drum of liquid radwaste at an authorized landfill.
