The handle is made from sustainable bamboo and this brush has softer, plant-based sisal bristles. This brush comes with a removable head so when the bristles have worn out, you simply need a new head! Store your scrubber bristle side down, to keep water from pooling on the handle. Most kitchen sponges are made of plastic and are not biodegradable. • Replaces plastic sponges • Compostable - remove bristles, recycle staples and compost bristles and handle! • Vegan
