Refrigerant

Appliances containing refrigerant (including Freon™), commonly found in refrigerators, air conditioners, water coolers, mini-fridges, freezers, and dehumidifiers, are not accepted at HHW mobile sites. However, they are accepted at the curb. To have your household refrigerant-containing appliance picked up curbside, visit the Bulky Item webpage.

There is a fee for the collection of these appliances due to the processing of refrigerant gas.

FOG

Fat, oil, and grease, or FOG, is a by-product of cooking many foods. Examples include meat, dairy products, soups, and anything with vegetable oil. FOG solidifies when cooled and can block and damage sewer pipes; thus, it should not be poured down the drain.

Residents can bring both liquid cooking oil and solidified FOG to HHW sites.

Please note:

• There is a limit of five (5) gallons of FOG per drop-off day.
• FOG must be in a container with a tight-fitting lid.

The Ada County Landfill Electronic Diversion Site accepts residential electronic waste (e-waste) such as large computers, printers, fax machines, and humidifiers. Located at the Ada County Landfill (10300 N. Seamans Gulch Rd, Boise) past the Scale Houses, open during Ada County Landfill regular hours.

• There is no limit to the number of electronic items that can be dropped off; however, an appointment is required if there are more than ten.

• The Ada County Material Reuse Program is open to all Ada County residents.
