How to Dispose of Charcoal

Queen City Disposal has some tips on how to safely get rid of the ashes after and ways to recycle the charcoal after grilling.

We look forward to the summertime for a lot of reasons, and one of those is grilling out. If you’re the master chef of the grill then you should know these simple tips for disposing of the ashes after the party is over.

Rule number one, remember that ashes can still be hot enough to burn and to start a renewed fire. 

  • It’s best to wait 48 hours before getting rid of the ashes. If you can’t wait for 48 hours, you can pour water on leftover coals and stir until it is completely cooled.
  • Wrap the cooled ash in aluminum foil and place it in a noncombustible, outdoor trash bin. 
  • Do NOT place them in your Queen City trash bin. These are made from heavy plastic which can melt under intense heat.

If you’re using additive-free lump charcoal:

  • Fertilize your plants. Charcoal ash contains potash, an important nutrient for some plants. It’s also a great way to increase the pH of the soil.

If you have a bag of used charcoal sitting around, there are a number of ways to use it up, even if grilling isn’t on your agenda:

  • Keep a few pieces in a perforated plastic bag in the refrigerator to kill odors.
  • Feed your compost pile to increase the carbon content.
  • Place a lump at the bottom of a flower vase to make cut flowers last longer.
  • Suppress garden weeds and maintain soil moisture by using charcoal as a mulch.
  • Mix crushed charcoal with orchid potting medium to increase the alkalinity.

Happy Grilling!
