Super Absorbent Polymers


Super Absorbent Polymers (SAPs) are dry granular polymer crystals.  They have the unique ability to absorb and retain large amounts of liquid.  In fact, they can absorb and retain up to 400 times their weight in liquids with minimal increase in volume or weight.  They are ideal for:

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

Super Absorbent Polymers stabilize liquid waste streams, dredge sediments and industrial sludges.  This results in a solid mass that is easy to handle and transport for landfill disposal.

Super Absorbent Polymers are also a cost-effective alternative to other bulk sorbents.  Kiln dust, portland cement, or sawdust can add volume and weight to a load.  In fact, they can double or triple the volume!  This extra volume increases both transport and disposal costs.  Since the polymers reduce volume and weight, costs are reduced as well.  Other advantages include:

  • No special preparation needed
  • Doesn’t biodegrade and release liquid
  • Forms a strong chemical bond with liquids
  • Reduces waste volume – expansion is less than 1%
  • Mixes quickly to save time
  • Waste passes the EPA 9095 paint filter test
  • Waste is safe for landfill disposal

Some of our clients ship contaminated soils to destination landfills by rail.  The EPA requires that liquids in the soil be in a solid form prior to transport.  Adding Super Absorbent Polymers during the loading process is an effective solution.  They safely solidify both hazardous and non-hazardous wastes.

They are ideal for use with our Black Stallion Rail Gondola Liners and other applications.  Please call us at 609-971-8810 so we can help you select the right material for your needs.
