This environmental bamboo toothbrush is a simple and sustainable option for brushing your teeth. Made from bamboo, a natural cellulose fibre, they are biodegradable, environmentally sustainable and do not pollute the environment. Even the packaging is biodegradable. The bristles are made from a BPA free polymer. Whilst this isn't biodegradable, there isn't yet an option on the marketplace that is. The bristles result in a much smaller impact to the earth than plastic toothbrushes. Dispose of by cutting the bristles off into your regular garbage, and then dispose of the handle into the compost or landfill - the handle will break down into the soil.
