Learning how to build a compost bin is one of the most rewarding steps you can take toward a greener lifestyle. Whether you’re looking to reduce household waste or boost your garden’s health, composting is a cost-effective and eco-friendly solution anyone can do at home.
In this beginner-friendly guide, we’ll show you how to build a compost bin using wooden pallets and walk you through the basics of composting success—from materials and setup to maintenance tips. By the end, you’ll have a functional compost bin and the knowledge to start producing your own nutrient-rich compost.
What You’ll Need to Build a Compost Bin
One of the best things about building your own compost bin is how little you need to get started. You don’t have to be a master carpenter—just gather these simple tools and materials:
-
4 wooden pallets (reclaimed or new)
-
Zip ties, screws, or nails
-
Drill or hammer
-
Optional: chicken wire or tarp for lining
Pro tip: Reusing pallets is both eco-friendly and budget-conscious. Check out a guide on how to reuse pallets in landscaping for safety tips and creative ideas.
Step-by-Step: How to Build a Compost Bin with Pallets
Let’s walk through the process of assembling your compost bin. It’s easier than you think!
1. Choose the Right Location
Pick a flat, well-drained area that gets partial sunlight. This will help regulate temperature and airflow, both of which are important for decomposition. Make sure it’s easy to access all year long.

2. Form the Frame
Stand three pallets upright in a “U” shape to form the back and sides. Secure the corners together using zip ties, screws, or nails. Make sure the structure is stable.
3. Add the Front Panel
Attach the fourth pallet to the front of your bin. You can fix it permanently or leave it removable for easier compost turning and removal.
4. Optional Lining
If you’re composting small or loose items, line the inside of the pallets with chicken wire or hardware cloth to keep everything contained while still allowing for airflow.
How to Start Composting
Now that your DIY compost bin is built, it’s time to start filling it with organic matter. Composting requires a balance of two key ingredient types:
-
Greens (nitrogen-rich) – kitchen scraps, coffee grounds, fresh grass clippings
-
Browns (carbon-rich) – dry leaves, cardboard, shredded paper, straw
Layer these materials like a lasagna. Keep the pile moist but not soggy, and turn it every 2–3 weeks to introduce oxygen and accelerate decomposition.
Want to give your compost a boost? Mix in a bit of Orgro Compost or our Topsoil Compost Blend to introduce beneficial microbes and speed up the breakdown process.
What Not to Add to Your Compost Bin
Even if you know how to build a compost bin, success depends on what you put into it. Avoid adding these materials:
-
Meat, bones, or dairy
-
Oily or greasy food waste
-
Pet waste or synthetic materials
-
Diseased plants or invasive weeds
These can attract pests or disrupt the composting process.
Composting Tips for Beginners
Here are a few key practices to get the most out of your composting experience:
Chop Large Items
Break down thick stems or branches into smaller pieces to help them decompose faster.
Watch the Moisture
Your compost should feel like a wrung-out sponge. If it’s too dry, add water or more green materials. If too wet, add dry browns or mix in screened topsoil to absorb moisture.
Keep Turning
Turning your compost every few weeks introduces air, which speeds up microbial activity and helps prevent odor.
