Tools Required

• Oklin GG-20 compost bin
• Compostable bags (optional)
• Aerator tool (optional)
• Countertop caddy (optional)
• Carbon-rich material (e.g., shredded paper, dry leaves)

Unboxing and Initial Setup

When you receive your Oklin GG-20 compost bin, the first step is to carefully unbox it and check for any damage during shipping. Ensure that all parts, including the bin, lid, aerator (if included), and any filters, are intact and free from defects.

1. Place the compost bin in a well-ventilated area. Choose a convenient space in your kitchen or near the composting area for easy access and odor management. The Oklin GG-20 is compact, making it ideal for kitchen countertops or small spaces.
2. Install the aerator (if applicable). The aerator can be inserted into the lid or the compost bin to enhance airflow, aiding the decomposition process. This step is optional but recommended for optimal performance.
3. Line the bin with a compostable bag (optional). While the bin is designed for easy cleaning, some users prefer lining it with compostable bags to reduce mess. Ensure the bag is securely fitted and does not obstruct airflow.
4. Prepare the bin for composting. Add a small layer of carbon-rich material at the bottom of the bin, such as shredded paper or dry leaves. This helps balance the nitrogen-rich food scraps and improves airflow.

Operating the Oklin GG-20 Compost Bin

Adding Compostable Materials

To use the Oklin GG-20 effectively, it is important to add the right materials.

• Food scraps: You can add fruit and vegetable peels, coffee grounds, eggshells, and other organic kitchen waste. Avoid adding dairy products, meats, oils, and non-compostable materials like plastic or metal.
• Balance the ingredients: Ensure a good mix of “green” (nitrogen-rich) and “brown” (carbon-rich) materials for efficient composting. A 2:1 ratio of greens to browns works well for most composting setups.

Monitoring Moisture and Aeration

• Check the moisture levels. The Oklin GG-20 should have a slightly moist environment, similar to a damp sponge. If the compost is too dry, add a small amount of water; if too wet, increase the ratio of dry materials like leaves or paper.
• Aerate regularly. To speed up decomposition and prevent odor, use the aerator tool or gently stir the contents. Proper airflow is crucial to avoid the buildup of harmful bacteria.

Adjusting for Odor Control and Efficiency

One of the key benefits of the Oklin GG-20 is its ability to minimize odors. However, ensuring the system works efficiently requires some attention.

• Lid and filter use: Ensure that the lid is tightly sealed after every use to prevent odors from escaping. The Oklin GG-20 comes with a built-in air filtration system that minimizes smells. Replace the filter periodically according to the manufacturer’s instructions.
• Carbon-rich additions: If odors persist, add more carbon-rich material like shredded paper or leaves. This can help absorb excess moisture and neutralize odors.
• Temperature monitoring: If the compost is not breaking down as quickly as expected, it could be due to temperature imbalances. Ideally, your compost should stay between 130-160°F (54-71°C). If the temperature is too low, increase aeration or add more green materials.

Routine Maintenance of the Oklin GG-20

Cleaning and Upkeep

• Emptying the bin: Once the compost is ready (usually after 2-4 weeks), remove the contents and transfer them to your outdoor compost pile or garden bed. The Oklin GG-20 is designed for ease of emptying, and regular cleaning helps prevent build-up and odors.
• Cleaning the bin: Wash the bin with warm water and mild soap. Avoid using harsh chemicals that could affect the composting process. Ensure the bin is fully dry before reuse.

Filter Replacement

The Oklin GG-20 uses a filter to control odors. Check the filter regularly and replace it as needed. Most filters last between 3-6 months depending on usage. When replacing, ensure the new filter fits properly to maintain optimal performance.

Troubleshooting Common Set-Up Issues

Issue: Unpleasant Odors Persist

• Solution: Double-check the carbon-to-nitrogen ratio. If the compost is too “green” (high in nitrogen), it may generate smells. Add more carbon-rich material like shredded paper or sawdust. Ensure the lid is sealing properly to maintain a controlled environment.

Issue: Composting Process is Slow

• Solution: Make sure you are adding a good balance of greens and browns. If the compost is too dry, mist it lightly with water. Ensure the aerator is in place to improve airflow. You can also speed up the process by stirring the compost every few days.

Issue: Overflow of Compost Materials

• Solution: If the Oklin GG-20 is too small to handle your waste load, consider reducing the volume of compostable materials being added or increase the frequency of emptying the bin. For larger volumes, you may need a secondary compost bin.

Optimizing Composting Performance

Maximizing Space Efficiency

The Oklin GG-20 is designed to be compact, but it still requires careful management of space to avoid overflow. Use a countertop caddy to store food scraps temporarily, and add them to the compost bin daily. This practice will help prevent overloading and ensure an even composting process.

Using Compostable Bags

Although the bin itself is easy to clean, compostable bags can be a useful addition. They help contain the mess and make it easier to transfer compost from the bin to the garden. When using bags, ensure they are fully compostable and suitable for the Oklin GG-20.

Compatibility with Related Products

Countertop Caddies

A countertop caddy can be used alongside the Oklin GG-20 to collect kitchen waste before transferring it to the compost bin. This helps reduce trips to the composting bin and keeps odors contained.

Compostable Bags

If you opt to use compostable bags, ensure they are certified and compatible with your composting system. These bags can help reduce cleanup time and ensure the contents break down properly in the composting process.

Aerators

An aerator can significantly improve airflow and speed up decomposition. While the Oklin GG-20 comes with an optional aerator, other models may be used as well, depending on size and compatibility.

Comparison with Similar Composting Bins

The Oklin GG-20 stands out for its advanced odor control system and compact design. Compared to other bins like the FoodCycler or the NatureMill, the Oklin GG-20 offers a balance of small size and high efficiency. However, for larger households or heavier waste loads, models with more capacity might be more appropriate.

Conclusion

The Oklin GG-20 is an excellent composting solution for beginners looking to manage kitchen waste efficiently. By following the setup and maintenance guidelines, troubleshooting common issues, and optimizing the composting process, you can achieve successful results while minimizing odors and maintaining a clean kitchen environment.
