Book 29, Question 103
What shouldn't go in a compost bin?
Meat, fish, dairy, and greasy foods can attract rats, raccoons, and flies, and may cause bad smells.
Pet waste can carry germs that make people sick. Diseased plants and weeds with seeds may spread problems to the garden. Plastic, metal, and glass don't break down. Stick with plant scraps, leaves, and paper. When unsure, ask a grown-up or look at local rules.
