4. Operation Guide
4.1 What to Compost
Successful composting relies on a balance of "green" (nitrogen-rich) and "brown" (carbon-rich) materials.

Image 4.1: Guide to fermentable (compostable) and non-fermentable (non-compostable) materials.
Fermentable Materials (Suitable for Composting):
- Fruit and vegetable scraps
- Coffee grounds and tea leaves
- Bread and cereals
- Garden waste (dead plants, leaves, small branches)
- Eggshells (crushed)
Non-Fermentable Materials (NOT Suitable for Composting):
- Dairy products
- Meat and bones
- Greasy food
- Plastic, glass, and metal
- Pet waste
- Diseased plants
4.2 Adding Materials
To add materials, simply open one side of the dual-opening flip lid.

For best results, aim for a mix of green and brown materials. Chop larger items into smaller pieces to speed up decomposition.

4.3 Retrieving Finished Compost
Once materials have fully decomposed (typically 1-2 months depending on conditions and materials), the nutrient-rich compost can be retrieved from the bottom of the bin.
- Locate the snap-lock fertilizer door at the bottom of the bin.
- Unlatch and open the door.
- Scoop out the finished compost. The compost at the bottom will be the oldest and most decomposed.
- Close the door securely after retrieving compost.
5. Maintenance
- Moisture Levels: The compost pile should be consistently moist, like a wrung-out sponge. If too dry, add water; if too wet, add more brown materials (e.g., dry leaves, shredded paper).
- Aeration: While the bin has ventilation ports, occasionally turning the compost with a pitchfork or aerator can speed up the process and prevent compaction.
- Cleaning: Periodically clean the exterior of the bin with water and a mild detergent if desired. Ensure ventilation holes remain clear of debris.
- Pest Control: Proper composting (avoiding meat, dairy, and greasy foods) helps deter pests. Ensure the lid is always closed securely.
6. Troubleshooting
Problem | Possible Cause | Solution |
---|---|---|
Compost smells bad (rotten eggs/ammonia) | Too much green material, not enough air, too wet. | Add more brown materials (leaves, cardboard), turn the pile, ensure ventilation ports are clear. |
Compost is not breaking down | Too dry, not enough nitrogen, lack of aeration. | Add water, add more green materials (food scraps), turn the pile. |
Pests (flies, rodents) | Exposed food waste, unsuitable materials (meat, dairy). | Bury food scraps under brown material, ensure lid is closed, avoid adding prohibited items. |
Compost is too wet/slimy | Too much moisture, not enough brown material. | Add dry brown materials (shredded paper, dry leaves), turn the pile to aerate. |
