2. Tools and Materials for a DIY Compost Bin

Before you begin building your compost bin, gather the following tools and materials. Many of these items can be sourced inexpensively or repurposed from items you already have at home.

Tools

• Drill: For creating air holes in your bin or assembly.
• Saw (if needed): For cutting wood or other materials to size.
• Screwdriver: For assembling wooden bins.
• Measuring Tape: To ensure accurate dimensions.
• Gloves: To protect your hands while handling materials.

Materials

• Wood Pallets or Planks: For creating a wooden compost bin.

  2. Leave the front panel unattached or install hinges for easy access.
  3. Add a lid or cover if desired.

2. Plastic Storage Bin Compost Bin

• What You’ll Need: A large plastic storage bin with a lid, drill, and optional mesh lining.
• Best For: Small spaces, apartments, or indoor composting.
• How-To:
  1. Drill holes along the sides, bottom, and lid for ventilation.
  2. Place the bin on bricks or a tray to allow excess moisture to drain.
  3. Add your compost materials and mix occasionally.

3. Trash Can Compost Bin

• What You’ll Need: A metal or plastic trash can, drill, bungee cord (optional), and lid.
• Best For: Urban settings or those with limited space.
• How-To:
  1. Drill holes around the trash can for air circulation.
  2. Secure the lid with a bungee cord to keep pests out.
  3. Roll the bin occasionally to aerate the compost.

4. Wire Mesh Compost Bin

• What You’ll Need: Chicken wire or hardware cloth, wire cutters, and zip ties or metal ties.
• Best For: Large yards or gardens that can accommodate an open-style bin.
• How-To:
  1. Cut the wire to your desired size and shape it into a circular bin.
  2. Secure the ends with zip ties or metal wire.
  3. Anchor the bin to the ground for stability.

4. Step-by-Step Guide to Building a DIY Compost Bin

Let’s create a simple, beginner-friendly compost bin using a plastic storage container as an example:

Materials Needed

• 1 large plastic storage bin with a lid.
• Drill with a ¼-inch bit.
• Bricks, tray, or stand for elevation.

Instructions

1. Prepare the Bin
   • Wash the storage bin to remove any residue.
   • Ensure the lid fits securely to keep moisture and pests out.
2. Drill Ventilation Holes
   • Drill evenly spaced holes on all sides, the bottom, and the lid for air circulation.
   • Holes should be about 2–3 inches apart.
3. Elevate the Bin
   • Place the bin on bricks or a tray to allow drainage. Excess liquid (compost tea) can collect underneath for use as fertilizer.
4. Add Composting Materials
   • Layer “greens” (food scraps) and “browns” (dry materials like leaves or cardboard) to start your compost pile.
   • Maintain a 2:1 ratio of browns to greens for balanced composting.
5. Mix Regularly
   • Use a small rake or stick to stir the contents every few days, ensuring proper aeration and decomposition.
6. Monitor and Adjust
   • Check the moisture level—compost should be as damp as a wrung-out sponge. Add more browns if it’s too wet or greens if it’s too dry.

Pro Tip:

Keep a small compost caddy or bucket in your kitchen to collect scraps before transferring them to your outdoor bin.

5. What to Compost and What to Avoid

Understanding what can and cannot go into your compost bin is crucial for healthy, efficient decomposition.

What to Compost

• Greens (Nitrogen-Rich):
  • Fruit and vegetable scraps.
  • Coffee grounds and tea bags (plastic-free).
  • Fresh grass clippings and garden waste.
• Browns (Carbon-Rich):
  • Dried leaves, twigs, and straw.
  • Shredded paper and cardboard.
  • Sawdust from untreated wood.

What to Avoid

• Meat, dairy, and oily foods (they attract pests and create odor).
• Plastic, metal, and glass.
• Diseased plants or invasive weeds.
• Pet waste or litter.

Pro Tip:

Chop large items like vegetable scraps or branches into smaller pieces to speed up decomposition.

6. Maintaining Your Compost Bin

Proper maintenance ensures your compost bin produces nutrient-rich compost efficiently. Here’s how to keep your bin in good shape:

Aeration

• Mix or turn your compost regularly to improve airflow and prevent odor buildup.

Moisture

• Maintain the right moisture level—compost should feel damp but not soggy.
• Add water or greens if it’s too dry, or browns if it’s too wet.

Temperature

• A well-maintained compost bin should feel warm to the touch, as decomposition generates heat.

Pest Control

• Cover food scraps with browns to discourage pests.
• Use a secure lid or fine mesh to keep rodents and insects out.

Pro Tip:

Finished compost should be dark, crumbly, and earthy-smelling—ready to enrich your garden soil!

7. Using Your Finished Compost

Once your compost is ready, it’s time to put it to good use in your garden or home. Here are a few ideas:

In the Garden

• Mix compost into garden beds to enrich the soil before planting.
• Use it as mulch around plants to retain moisture and suppress weeds.

For Potted Plants

• Add compost to potting soil for an organic nutrient boost.

Lawn Care

• Spread a thin layer of compost over your lawn to promote healthy grass growth.

Pro Tip:

Sift your compost through a screen to remove any large, undecomposed pieces before use.

10 FAQs About DIY Compost Bins

1. How long does it take for compost to break down?

It typically takes 2–6 months, depending on the materials, temperature, and maintenance.

2. Can I compost in the winter?

Yes! Decomposition slows in colder months, but adding materials and stirring occasionally keeps the process going.

3. What should I do if my compost smells bad?

Bad odors usually mean there’s too much moisture or not enough browns. Add dry materials and mix well.

4. Can I compost indoors?

Yes! A small plastic bin, bokashi system, or worm composting setup works well for indoor composting.

5. How do I prevent pests in my compost bin?

Cover food scraps with browns and keep the bin secured with a tight-fitting lid.

6. How do I know when my compost is ready?

Finished compost is dark, crumbly, and smells earthy, with no visible food scraps.

7. Can I compost weeds?

Avoid composting invasive weeds or seeds unless your bin reaches high temperatures to kill them.

8. How do I speed up the composting process?

Chop materials into smaller pieces, maintain proper aeration, and ensure the right greens-to-browns ratio.

9. What’s the best location for my compost bin?

Choose a sunny spot with good drainage, away from direct wind or heavy shade.

10. Do I need a lid for my compost bin?

While not mandatory, a lid helps control moisture, keeps pests out, and maintains heat for faster composting.
