How to Make a Compost Bin: A Step-by-Step Guide

Composting is a fantastic way to recycle organic waste, reduce your carbon footprint, and create nutrient-rich soil for your garden. Making your compost bin is easy, cost-effective, and can be accomplished with just a few materials. Follow these steps to create your compost bin and turn waste into a valuable resource!
Materials Needed:
- A large plastic bin with a lid (preferably dark-1/4-inch coloured)
- Drill with a 1/4 inch bit
- Newspaper or cardboard
- Garden soil
- Organic waste (fruit and vegetable scraps, coffee grounds, eggshells, grass clippings, leaves, etc.)
- Water

Step 1: Choose the Right Bin
Select a large plastic bin with a lid. The bin should be at least 18 gallons in size, but larger bins will hold more composting material. A dark-coloured bin works best, as it absorbs heat, which aids in the composting process.

Step 2: Prepare the Bin
To create adequate airflow and drainage, you must drill holes in your bin. Using a 1/4-inch drill bit, make holes in the sides, bottom, and lid of the bin. Space the holes about 1-2 inches apart. These holes will allow oxygen to flow and excess moisture to drain out, both of which are crucial for the composting process.

Step 3: Create a Base Layer
Place a layer of newspaper or cardboard at the bottom of the bin. This layer helps to absorb excess moisture and prevents pests from entering the bin. Tear the newspaper or cardboard into small pieces for the best results.

Step 4: Add Soil
Add a few inches of garden soil to the newspaper or cardboard layer. The soil introduces beneficial microorganisms that help break down the organic material in your compost.

Step 5: Start Adding Organic Waste
Begin adding your organic waste to the bin. This can include fruit and vegetable scraps, coffee grounds, eggshells, grass clippings, and leaves. Avoid adding meat, dairy, or oily foods, which can attract pests and cause unpleasant odours.

Tips for Adding Waste:
Chop more considerable organic waste into smaller pieces to speed up the decomposition process.
Aim to balance green materials (fruit and vegetable scraps, grass clippings) and brown materials (leaves, cardboard). A good ratio is about three parts brown to 1 part green.

Step 6: Maintain the Compost
To ensure your compost breaks down efficiently, it must be aerated and moist (but not too wet). Every few days, use a garden fork or shovel to turn the compost, mix the materials and allow air to circulate. If the compost appears dry, add a bit of water. If it’s too wet, add more brown materials like newspaper or cardboard.

Step 7: Monitor and Troubleshoot
Keep an eye on your compost bin to ensure it’s working correctly. Odour: A healthy compost bin should smell earthy. If it smells bad, it may be too wet or lack enough brown materials. Pests: If you notice pests, avoid adding prohibited items like meat or dairy and make sure your bin is sealed correctly.

Step 8: Harvest the Compost
After a few months, your compost should be ready to use. You'll know it's ready when it looks dark, crumbly, and has an earthy smell. At this point, you can harvest the compost by sifting it through a screen or simply using it directly in your garden.

Conclusion
Creating a compost bin is a simple and rewarding way to manage organic waste and enrich your garden soil. By following these steps, you'll be well on your way to producing your compost and contributing to a healthier environment. Happy composting!
