Composting is an eco-friendly method to transform kitchen scraps and yard waste into nutrient-rich soil. Among the various composting methods, the double barrel compost bin stands out for its efficiency and practicality. This article will guide you through the ins and outs of using a double barrel compost bin, ensuring that your composting experience is as smooth and effective as possible.
What is a Double Barrel Compost Bin?
A double barrel compost bin typically consists of two separate, rotatable barrels mounted on a sturdy frame. Each barrel serves as a distinct compartment for composting, allowing you to manage two batches at the same time. This design offers several advantages:
- Efficient Use of Space: By having two barrels, you can maintain two different stages of composting simultaneously.
- Faster Composting: Turning the barrels makes it easy to aerate your compost, promoting quicker decomposition.
Double barrel compost bins are particularly popular among gardeners who wish to produce finished compost regularly without taking up too much space.
Benefits of Using a Double Barrel Compost Bin
Utilizing a double barrel compost bin has a plethora of advantages. Here are some key benefits:
1. Continuous Composting
With two barrels, you can always have one bin “cooking” while you add new scraps into the other. When one barrel is full and ready for use, just switch to the other one.
2. Improved Aeration
The rotating barrels allow for better aeration compared to traditional compost piles. Regular turning ensures that air circulates throughout the compost, speeding up the decomposition process.
3. Versatility
A double barrel can manage a variety of compostable materials, including kitchen scraps, yard waste, paper, and even certain types of biodegradable plastics.
Setting Up Your Double Barrel Compost Bin
Setting up your double barrel compost bin requires some careful planning and execution. Below is a detailed guide on how to do it effectively.
1. Choosing the Right Location
Consider the following when selecting a location for your compost bin:
- It should be easily accessible for adding new materials and harvesting finished compost.
- Choose a shaded area to help maintain temperature and moisture levels.
2. Preparing the Base
Start by placing the compost bin on bare soil or on a gravel surface. This setup aids drainage and encourages beneficial microorganisms from the soil to enter the compost.
3. Layering Your Compost Materials
When adding materials to your double barrel, create a balance of “greens” (nitrogen-rich materials) and “browns” (carbon-rich materials).
The Ideal Ratio
Aim for a ratio of 2:1 of browns to greens. This balance will help your compost break down efficiently. Here’s how you can segregate:
- Greens (Nitrogen): Kitchen scraps (fruits and veggies), grass clippings, coffee grounds.
- Browns (Carbon): Dried leaves, straw, cardboard.
How to Use Your Double Barrel Compost Bin
Once you have set up your double barrel compost bin, it’s time to start using it. Here’s a step-by-step guide to effective composting.
1. Adding Materials
As you accumulate kitchen scraps and yard waste, add them into the open barrel. Layer materials by mixing greens and browns to maintain airflow and balance the nitrogen-carbon ratio.
2. Turning the Barrels
To aerate your compost effectively, periodically rotate the barrels bi-weekly or whenever you add new material.
Why Rotation Matters
Rotation breaks up clumps of material, allowing for greater exposure to air and moisture, which is crucial for microbes that break down the compost.
3. Monitoring Moisture Levels
Moisture content is an essential factor in successful composting. The ideal moisture level should be comparable to a damp sponge. If it feels too dry, sprinkle some water in; if it’s too wet, add more dry browns.
4. Harvesting Your Compost
As the compost breaks down, it will take on a dark, crumbly texture and earthy smell. Depending on conditions, it may take several weeks to several months for compost to mature. Here’s how to harvest:
- When one barrel has finished compost, open the access hatch (if available) or remove the entire barrel.
- Use a garden trowel or shovel to extract the compost from the bottom, as this part will be the most decomposed.
- Transfer it to a container for use in your garden.
Tips for Successful Composting in a Double Barrel Bin
Maximizing the efficiency of your double barrel compost bin involves some best practices. Here are expert tips to consider:
1. Avoid Certain Materials
Not all materials should find their way into your compost bin. Avoid meat, dairy, and oily foods, which can attract pests and create odors. Additionally, steer clear of any diseased plants or weeds that may spread seeds.
2. Chop Materials Smaller
Cutting kitchen scraps and yard waste into smaller pieces can significantly speed up the decomposition process. Smaller pieces have a greater surface area, allowing microbes to break them down more easily.
3. Temperature Maintenance
Keep an eye on the temperature of your compost. The ideal range for active composting is between 130°F to 160°F. If it gets too cold, consider insulating your bins or covering them to retain heat.
Challenges and Solutions in Double Barrel Composting
Despite its many advantages, double barrel composting can pose certain challenges. Below are common issues and tips on how to resolve them.
1. Smelly Compost
If your compost has an unpleasant odor, it could be a sign of too much moisture or an imbalance of nitrogen and carbon.
- Solution: Adjust the ratio by adding more browns or ensuring better airflow through regular turning.
2. Pests and Rodents
Unwanted guests such as pests and rodents can be a concern with composting.
- Solution: Keep compost bins securely closed, and avoid adding any animal products. Also, regularly turning the compost can deter pests.
3. Slow Decomposition
If your compost is taking too long to break down, it may be due to insufficient aeration or lack of moisture.
- Solution: Turn the compost more frequently and check moisture levels; adjust accordingly.

What is a double barrel compost bin?
A double barrel compost bin is a type of composting system that consists of two separate containers mounted on a rotating base. This design allows one barrel to be filled with organic waste while the other is left to mature. The rotation helps to mix the materials and aerate the composting process, promoting faster decomposition.
This bin style is particularly beneficial for gardeners who want to efficiently compost kitchen scraps and yard waste. It offers an organized way to create compost without the need for manual turning, making it user-friendly and efficient for composting enthusiasts of all levels.
How do I start composting with a double barrel compost bin?
Starting composting in a double barrel bin involves a few easy steps. First, you should choose a suitable location for your bin, ideally a spot that gets some sun and has good drainage. Begin by filling one barrel with a mix of green materials (like fruit scraps and grass clippings) and brown materials (such as dried leaves and cardboard). It’s essential to maintain a balanced carbon-to-nitrogen ratio for optimal decomposition.
Once the first barrel is filled, you can start adding to the second barrel. When the first barrel is fully composted, simply rotate it out, opening the lid to retrieve finished compost, and begin filling it again while letting the second barrel mature. This alternating system ensures that you have a continuous supply of compost available.
What materials can I compost in a double barrel bin?
In a double barrel compost bin, you can compost a variety of organic materials, including kitchen scraps like vegetable peelings, fruit cores, and coffee grounds. Yard waste such as grass clippings, leaves, small branches, and wood chips are also suitable.
