This project was built and designed by Stan Sullivan. It’s a simple compost bin build that turns yard waste and food scraps into nutrient-rich soil, offering an eco-friendly solution for any home garden.

Composting reduces waste, improves your garden’s soil, and makes for a great educational family project. Stan’s design focuses on accessibility, durability, and ease of use, making it a smart starting point for anyone new to composting.

Why Composting Makes Sense

Composting is an effective way to recycle organic waste that would otherwise end up in landfills. It transforms kitchen scraps, grass clippings, leaves, and paper into a valuable soil amendment.

There are environmental, financial, and practical benefits to composting. Instead of buying fertilizer or bagged compost, you can produce your own for free—all while reducing methane emissions and improving the health of your garden.

Choosing a Good Spot for Your Bin

One of the first steps in this project is picking the right location. Stan recommends an area that’s shaded part of the day, drains well, and is easy to access for adding waste and turning the pile.

Positioning your compost bin close to the kitchen or garden makes it easier to use regularly. You want a location that’s dry but not too dry—some sunlight helps speed up decomposition without drying the pile out completely.

Materials and Flexibility

Stan’s build uses scrap wood and wire mesh, but the design is flexible. You can repurpose old pallets, crates, or fencing depending on what’s available.

The important thing is airflow and access. The compost bin should be breathable to allow aerobic decomposition and easy to open so materials can be added and turned with minimal hassle.

Building the Structure

Stan constructs a simple three-sided box with slats spaced slightly apart to encourage airflow. The design includes an open front or a removable panel, which makes it easier to turn the pile or remove finished compost.

You don’t need advanced joinery for this build—screws and exterior-grade fasteners are enough to hold everything together. The final footprint is compact but roomy enough to support a steady stream of composting materials.

What to Add to Your Bin

Once the bin is built, it’s time to fill it. Successful composting depends on balancing “greens” and “browns.”

Green materials include things like food scraps, grass clippings, and coffee grounds. These are nitrogen-rich and provide moisture. Brown materials like dried leaves, shredded paper, or cardboard add carbon and help with airflow.

Stan recommends a rough 2:1 ratio of browns to greens. This encourages faster decomposition and avoids the pile becoming too wet or smelly.

Keeping the Process Going

Turning the pile with a shovel or pitchfork every few days introduces oxygen, which accelerates the composting process. It also helps distribute moisture and ensures materials break down evenly.

Stan notes that the compost should feel like a damp sponge—if it’s dry, you can add a little water or more green material. If it’s too wet, mix in extra browns like leaves or newspaper to soak up excess moisture.

Family Involvement and Education

Stan highlights how composting can be a fun and educational family project. Kids can help collect kitchen scraps, track the progress of the bin, and eventually use the compost in the garden.

Giving each family member a small role—such as measuring out materials or watering the pile—makes it easier to keep the system running. It also helps kids learn about decomposition, ecosystems, and sustainability.

Finished Compost and Garden Benefits

Once the compost is finished, it can be added directly to garden beds or mixed into potting soil. The rich organic matter helps retain moisture, improve drainage, and support plant health.

Using your own compost reduces the need for chemical fertilizers and provides a gentle, balanced feeding for vegetables, flowers, and shrubs. It also encourages healthy microbial life in the soil, which helps plants resist pests and disease.

Long-Term Value

Stan points out that composting is not only about immediate gains. Over time, it can help rebuild tired soil, reduce erosion, and minimize household waste.

The upfront time and materials are minimal, but the long-term rewards—healthier plants, better soil, and less trash—make it a project worth doing.
