Non-Hazardous Liquids & Semi-Solid Waste

Central Iowa businesses have a local alternative for non-hazardous liquid waste disposal at our Metro Park East Landfill, located in eastern Polk County. Permitted by the Iowa Department of Natural Resources, we can accept non-Resource Conservation and Recovery Act (RCRA) liquids and semi-solid waste.

Appointments Required

Liquids or semi-solids are only accepted during Special Waste acceptance hours and with prior approval and by appointment due to the off-loading process. Saturdays are by special appointment only.

Acceptance Criteria

Like other Special Waste, you must complete the Waste Profile Form prior to bringing liquids and semi-solid waste. Below is a list of some of the common waste streams we accept.

  • Industrial liquids 
  • Municipal waste
  • Rinse water
  • Latex paint, ink
  • Cooling fluids and cutting oils 
  • Food production waste
  • Tank bottoms and sludges
  • Drilling waste

Solidification Process & Disposal

The liquid waste is placed over a lined area and mixed with a solidifying material to convert the liquid into an acceptable solid form and is then placed in the landfill. Fly ash is used to solidifying the material.
