Floss is mostly made of nylon and comes in disposable plastic packaging. Being small and lightweight, floss thread is part of the plastic products that most easily enter the environment. Luckily some alternatives to plastic floss exist. The two main options are bio-based plastic suitable for vegans and silk floss. The former biodegrade in an industrial compost the latter biodegrades in your backyard compost.
Bambaw Silk Floss is a great replacement for nylon floss. The dental floss is mint flavored and 100% natural and compostable. Comes in a stainless steel dispenser you can refill a lifetime. The metal holder is light, convenient to carry and will not break.
This compostable floss is made of natural Ahimsa silk. Silk has been used by humans for thousands of years for its incredible strength and softness. So, it is well suited for interdental cleaning. The floss is coated with candelilla wax. The package includes one roll of dental floss and a metal dispenser. 50 meters of floss is enough for 200 flosses.
