The Closed Loop CLOe is a compact, high-efficiency kitchen composting system designed for sustainability-conscious households. It processes food waste efficiently, reduces odors, and transforms organic matter into nutrient-rich compost. This guide provides step-by-step instructions on installation, adjustment, maintenance, troubleshooting, and optimization to help you get the best performance from your CLOe unit.
Understanding the Closed Loop CLOe System
The CLOe compost bin integrates an advanced aeration system and moisture control mechanism to accelerate decomposition. It is engineered for small to medium-sized kitchens and works seamlessly with compostable liners and compatible carbon filters. The enclosed design minimizes odor and prevents pest intrusion, making it ideal for indoor use.
The CLOe’s unique advantage lies in its “closed loop” technology, which maintains a consistent balance between carbon, nitrogen, and oxygen. This balance ensures faster, cleaner composting and reduces the need for frequent manual adjustments.
Tools Required
- Phillips-head screwdriver
- Measuring tape
- Replacement carbon filter (optional)
- Compostable bin liner (compatible with CLOe)
Installation and Setup
Choosing the Right Location
Select a flat, dry, and well-ventilated area near your kitchen prep zone. The CLOe functions best away from heat sources such as ovens or stoves, as excessive heat can dry out compost prematurely. Ensure the unit is close to a power outlet if your model includes an integrated ventilation fan.
Initial Assembly
- Open the CLOe lid and remove all internal packaging materials.
- Insert the compost bucket and ensure it sits firmly within the base.
- Install the carbon filter by sliding it into the designated compartment under the lid.
- Place the compostable liner inside the inner bucket, ensuring a snug fit around the rim.
The system is now ready for first-time use.
Adjusting the System for Optimal Performance
Balancing Moisture and Aeration
To maintain ideal composting conditions, balance wet and dry inputs. Moisture levels should resemble a wrung-out sponge. If material appears soggy, add dry browns such as shredded paper or dried leaves. If it’s too dry, add a small amount of water or fresh food scraps.
The CLOe’s adjustable vent system can be opened or closed to regulate airflow. Open vents promote faster decomposition, while partially closed vents retain moisture in drier environments.
Managing Temperature and Load Size
Avoid overfilling the unit beyond the marked fill line. Overloading restricts airflow and slows composting. For best results, add waste in small batches and mix materials weekly using a composting aerator or hand trowel.
Routine Maintenance
Regular maintenance ensures consistent composting and extends the lifespan of your CLOe bin.
- Filter Replacement: Replace carbon filters every 3–4 months, depending on odor intensity and usage frequency.
- Liner Maintenance: Use certified compostable liners only. Remove and replace liners once weekly or when two-thirds full.
- Cleaning: Wipe the inner bucket and lid with mild soap and warm water every two weeks. Avoid harsh detergents that can disrupt microbial activity.
- Odor Control: Sprinkle a small amount of garden soil or compost starter in the bin to introduce beneficial microbes and minimize smell.
Troubleshooting Common Issues
Persistent Odor
Strong odors typically indicate anaerobic conditions caused by excess moisture or poor aeration. Stir the compost to introduce oxygen, replace the filter, and check the vent setting.
Slow Decomposition
If food scraps remain intact after several days, adjust the balance of greens (nitrogen) and browns (carbon). Increasing airflow and ensuring temperature stability also speeds up the process.
Condensation Under Lid
Excess condensation occurs when compost is too wet. Add dry material and leave the lid slightly ajar for several hours to restore balance.
Customization and Optimization
Enhancing Odor Control
To optimize odor absorption, install dual carbon filters or place a small pouch of baking soda beneath the filter compartment. Ensure the lid seals tightly after every use.
Improving Space Efficiency
If space is limited, position the CLOe under a countertop or inside a lower cabinet with at least two inches of clearance on each side for proper ventilation. The unit’s compact profile allows integration into most kitchen layouts.
Compost Maturity Monitoring
The CLOe’s composting cycle typically completes within two to four weeks, depending on usage. Mature compost will appear dark, crumbly, and earthy. If the compost is still wet or emits odor, continue aeration for several days.
Comparing the CLOe with Similar Compost Bins
Compared with other kitchen composters such as the Lomi or Vitamix FoodCycler, the CLOe offers a purely microbial process without heat drying or grinding. This method preserves beneficial microorganisms essential for soil enrichment. While electric units process waste faster, CLOe’s closed-loop system produces higher-quality compost and consumes no electricity.
Its sealed design also outperforms open-air caddies by preventing gnats and leaks. The ease of filter replacement and compatibility with standard compostable bags make it more user-friendly for daily use.
Compatibility with Composting Accessories
The CLOe is compatible with most BPI-certified compostable liners sized between 3–5 gallons. Use of non-compostable plastic liners is discouraged, as they disrupt airflow and composting efficiency.
The system also supports standard activated-carbon filters available through Closed Loop’s accessory line or equivalent third-party replacements. Compost accelerators, microbial boosters, or compost starter powders can be safely added to enhance decomposition.
For users integrating the CLOe into a broader composting setup, it works well with outdoor tumblers or worm bins for final curing and long-term storage of mature compost.
Final Calibration and Best Practices
Before each composting cycle, ensure the following:
- The carbon filter is properly installed and secure.
- The vent is set according to the season (more airflow in humid months, less in dry).
- Compost material is evenly mixed to prevent clumping.
Regular observation of compost texture and moisture ensures smooth operation. When properly maintained, the CLOe delivers odor-free composting and reduces household waste effectively.
Frequently Asked Questions
1. How often should I empty the CLOe compost bin?
Once the liner is two-thirds full or every 5–7 days, whichever comes first.
2. Can meat or dairy be added to the CLOe?
No. To avoid odor and pests, compost only plant-based kitchen waste.
3. What should I do if mold appears inside the bin?
A small amount of white mold is normal. If excessive, mix the compost and add dry browns to balance moisture.
4. Can I use the CLOe outdoors?
It is intended for indoor use. Outdoor placement may expose it to excess heat or moisture, affecting performance.
5. Is the CLOe dishwasher-safe?
No. Clean it manually using mild soap and warm water.
6. How do I know when the compost is ready?
Compost is mature when it becomes dark, crumbly, and earthy with no visible food residues.
By following these quick start tips, your Closed Loop CLOe will operate efficiently and sustainably, turning everyday kitchen scraps into nutrient-rich compost for your garden.
