Once your brush is ready to retire, remove the bristles using a pair of pliers — they need to be separated as they cannot be composted. Then take the bare bamboo handle and place it in your home compost bin, bury it in soil, or leave it in a green waste collection if available in your area.
Bamboo is a dense material, so it will take longer to break down than food waste, but it will decompose fully and naturally over time. To speed things up, you can snap or cut the handle into smaller pieces before composting.
