How to Make a DIY Burn Barrel

Have you ever needed an efficient way to dispose of yard waste, brush, or other burnable materials without the hassle of an open fire? I've been there too. Building a burn barrel is an easy and inexpensive way to handle those needs while controlling the burn safely and effectively. In this guide, I'm going to share how I made my own DIY burn barrel, tips that I learned along the way, and a few handy tricks that you might want to try yourself. Let's dive in.

Why Use a Burn Barrel?

Before we get into the steps, let's talk about why burn barrels are so handy. Burn barrels make a more controlled burn compared to a regular open fire. Because of the design—particularly with the airflow from holes near the bottom—they burn hotter and faster, reducing waste more quickly. Plus, they're safer since the barrel contains the fire, keeping it from spreading to other areas.

What You'll Need to Get Started

Here's what you'll need to make your own burn barrel:

A 55-gallon barrel: You can easily source one of these on Facebook Marketplace, Craigslist, or other secondhand places. Try not to spend more than $10. My barrel happened to be food-grade, which originally held applesauce. It was nice to know it was clean and safe for repurposing.
A way to cut the barrel: Depending on your barrel, you might need some metal-cutting tools. I got lucky with a barrel that had removable lids on both ends, so I didn't need to cut anything. But if your barrel has a solid bottom, you'll need to cut that out.
A drill or metal punch: You'll need to make some air holes at the bottom of the barrel to allow proper airflow.
A blow torch (optional but highly recommended): This is the fastest and easiest way to start your fire.

Step by Step Instructions

Learn how to make a DIY burn barrel with step-by-step instructions, from prepping the barrel to safety tips. Perfect for efficient burning and ash management.

Step 1: Prepping the Barrel

The first thing you need to do is prep your barrel. If your barrel has a solid bottom, you'll want to remove it. Cutting out the bottom will allow air to flow through the barrel, feeding the fire and helping it burn efficiently.

Tips for Cutting the Bottom

If you're cutting out the bottom yourself, it helps to use a reciprocating saw or grinder. Be careful during this step—wear protective gloves and eyewear to avoid any metal shards flying around. In my case, both lids were removable, so I was able to skip this step and move on.

Step 2: Adding Airflow Holes

After prepping the barrel, it's time to add some airflow. This is where your drill or metal punch comes in. The airflow is crucial because it allows oxygen to feed the fire, which helps it burn hotter and faster.

I drilled a single row of holes around the bottom of the barrel, just above where the bottom used to be. Some people like to do two rows, or cut slits instead of drilling holes. There's no hard-and-fast rule here, so feel free to customize it as you like. I kept it simple with one row, and it works perfectly fine for my needs.

Step 3: Setting Up the Burn Barrel

Once you have your barrel prepped with holes, you can set it up in your yard. Make sure to place it on a level surface away from any flammable materials like dry grass or leaves. If you want to improve airflow even more, consider setting the barrel on cinder blocks or bricks. This way, air can flow from underneath, keeping your fire strong and consistent.

Step 4: Start Burning!

Now comes the fun part—actually using your burn barrel. I used my blow torch to start the fire, but you can use matches or a lighter if you don't have a torch on hand. Just ignite the fire through one of the holes at the bottom.

Once the fire is going, it will burn upwards through the barrel. It only takes a few minutes for the fire to really take off. I found that it burns much faster than an open fire due to the airflow design, making it an efficient way to get rid of brush, leaves, and other burnable materials.

Step 5: Managing Ash Build-Up

After a few hours of burning, you'll start to see ash build up at the bottom of the barrel. This is normal and nothing to worry about. I used a stick to clear the holes to make sure air was still flowing properly. You can also empty out the ash periodically to keep the fire breathing well.

If you notice the fire dying down because of ash build-up, you can either clean out the barrel or consider adding a second row of holes for more airflow. I don't burn a ton of brush, so this doesn't happen often for me, but it's a good trick if you're planning on doing a lot of burning.

Lessons Learned: What Worked and What Didn't

When I first started using my burn barrel, I made the mistake of piling too much wood on top. While it made for a cool effect, it wasn't practical. The fire spread outside the barrel, defeating the purpose of using it for containment. My advice is to keep everything inside the barrel to prevent the fire from getting out of control.

Another tip: If you have a significant amount of material to burn, feed it into the barrel gradually. This keeps the fire going steadily without smothering it.

Safety Tips for Using a Burn Barrel

Safety is always the top priority when dealing with fire. Here are some essential safety tips to keep in mind:

Always have a water source nearby: Whether it's a hose or a bucket of water, make sure you can quickly put out the fire if needed.
Never leave the fire unattended: It might seem like a contained fire, but things can change quickly.
Watch for wind: Wind can carry embers and cause them to land outside the barrel, potentially starting a wildfire.
Keep the area clear: Make sure there's nothing around the barrel that can catch fire, like dry grass, woodpiles, or leaves.
