Super Absorbent Polymers


Super Absorbent Polymers (SAPs) are dry granular polymer crystals.  They have the unique ability to absorb and retain large volumes of liquid.  In fact, they can absorb and retain up to 400 times their weight in liquids with minimal increase in volume or weight.  When a liquid waste stream needs to be stabilized, Super Absorbent Polymers are an effective solution.  They are suitable for applications such as:

  • petrochemical spills
  • remediation projects
  • landfill closures
  • environmental cleanup projects

Super Absorbent Polymers quickly stabilize dredge sediments, aqueous waste streams and industrial sludges.  As a result, the solid waste is easy to transport for landfill disposal.

Super Absorbent Polymers are also an economical alternative to other bulk sorbents.  Kiln dust, portland cement, or sawdust can add volume and weight to a load.  In fact, they often double or triple the volume!  Because Super Absorbent Polymers reduce liquid waste volume, they reduce transport and disposal costs.  Advantages also include:

  • Requires no special preparation for use
  • Doesn’t biodegrade and release liquid
  • Forms a strong chemical bond with liquid wastes
  • Minimizes waste volume – typical expansion is less than 1%
  • Mixes quickly to improve production efficiency
  • Waste passes the EPA 9095 paint filter test
  • Solidified waste is approved for landfill disposal

Some of our clients ship contaminated soils to destination landfills by rail.  To comply with EPA regulations, liquid wastes must be solidified prior to transport. Adding Super Absorbent Polymers during the loading process is an effective solution.  They safely solidify both hazardous and non-hazardous wastes.

Our Super Absorbent Polymers work well with our Black Stallion Rail Gondola Liners.  They are also effective for other applications.  Please call us at 609-971-8810 so we can help you select the right material for your needs.
