Kitchen and garden waste is usually used in small-scale vermicomposting systems, where earthworms and other microorganisms digest organic waste. Such feedstock for worms includes:
- All fruits and vegetables (including citrus and other fruits high in acids)
- Fruit and vegetable peels and ends
- Coffee grounds and filters
- Tea bags (even tea high in tannins)
- Various grains: bread, crackers and cereal (even moldy and stale)
- Rinsed off eggshells
- Grass clippings and leaves (free from pesticides)
