Did you know that Americans light up their grills over 60 million times each year, releasing not just the mouth-watering aroma of barbecue but also tons of charcoal ash? While the tantalizing scent of grilled food is a summer staple, what happens after the last burger is flipped? The proper disposal of charcoal is crucial for both safety and the environment, yet it’s often overlooked in the flurry of outdoor feasting.
In this guide, we’ll uncover the best practices for disposing of charcoal and ash after grilling. It’s not just about scraping out your grill and tossing the remnants into the trash. Instead, you need to consider factors like cooling times, disposal methods, and environmental impact.
So, how do you properly dispose of charcoal after grilling?
Here are the steps to properly dispose of charcoal after grilling:
- Extinguish the Charcoal: Close the lid and vents on your grill and wait at least 48 hours until the charcoal and ash have completely cooled.
- Separate Ash from Unused Charcoal: If there are still some unburned pieces of charcoal mixed with your ash, you can reuse them. Separate the charcoal from the ash using a kick ash basket or some other means of separation.
- Reuse Unburned Charcoal: You can use any half-burned pieces of charcoal on your next grilling session. Simply set aside the chunks of charcoal, or put them back in your grill for later use.
- Dispose of the Ashes: Once the ashes have thoroughly cooled, scoop them into used aluminum foil and wrap them up. You can then dispose of the aluminum foil in your garbage bin. Make sure you wait at least 48 hours after you grill before doing this.
Remember, the disposal method may depend on the type of charcoal you’re using. There are two different types: charcoal briquettes and lump charcoal.
Lump charcoal is all-natural, made from burning wood in the absence of oxygen, and can be disposed of in various ways, including composting or adding directly to your garden soil.
However, briquettes are made with additives that help them burn consistently and hold them together, limiting disposal options.
Always check your charcoal bag to see if the kind you use is additive-free or not.
With these points in mind, let’s dive into the details of how to keep your grilling experience not only delicious but also responsible, ensuring a safer and more eco-friendly approach to charcoal disposal.
