It’s a common question—and one with real consequences. Whether you're using natural lump charcoal or briquettes with additives, disposing of charcoal incorrectly can be unsafe, messy, or harmful to the environment. At 1-800-GOT-JUNK?, we’ve helped thousands of customers safely dispose of charcoal, ash, and old grills—especially during peak barbecue season.
This guide will walk you through how to dispose of charcoal, ash, and grilling byproducts responsibly, so you can keep the good times going.
What to do with charcoal ash
Start by safely cooling your charcoal. Close the grill vents and wait 48 hours, or carefully douse with water and stir to ensure the coals are completely out. Once cooled, collect the ash in a sealed metal container or double-bag it in heavy-duty trash bags.
Then choose a disposal method based on the type of charcoal you used:
Compost additive-free natural wood charcoal ash
If you use natural wood charcoal without chemicals or lighter fluid, the ash can be composted in small amounts or sprinkled into your garden; certain plants thrive with added alkalinity.
Best for: Gardeners or anyone using clean-burning fuel.
Trash briquette ash containing additives
Briquettes that contain additives or lighter fluid should never go in your compost. These belong in your regular trash, after the ash is completely cool and sealed in a disposable container or bag.
Reuse unused or unburned charcoal
Got leftover charcoal that didn’t fully burn? Save it for your next grill session. Store dry pieces in an airtight container in a cool, dry place.
Dispose of unused charcoal with additives at a hazardous waste center
Unopened or leftover briquettes with added chemicals should be dropped off at your local hazardous waste facility.
Best for: Cleaning up after tailgating events, block parties, or old BBQ supplies.
Hire a junk removal service

Store it properly in a dry, sealed container for future use.
- Give it away to a neighbor, friend, or local group.
