Is That Really Compostable?

Backyard compost bins can take most food scraps, but should not include bones, meat, fish, dairy, or pet feces because they may carry pathogens or attract animals. Freezing scraps and covering them with leaves or straw helps reduce odors and pests. Vermicomposting accepts many of the same scraps, but worms often dislike garlic, onions, and citrus peels. Large-scale composting systems can handle a wider range of waste, including meat, bones, dairy, and sometimes pet feces, though you should always check with the operator about what is allowed.
