Disposal options
Substances used to melt ice on sidewalks and driveways–chemical ice melt, rock salt, road salt, sodium chloride–are not hazardous and can be thrown away in your household trash.
Notes
Salt and potassium chloride bags must not be put into your recycling or put in with other bags returned to grocery or box stores. We have not found an option for recycling these bags, and they must be disposed of as trash.
