All our cloths are 100% biodegradable and compostable.
The Cellulose cloths have some cotton as well as cellulose fibre. Once the cloths start to wear a little too much, cut them into smaller pieces and put them into your compost. They will decompose under compost conditions and turn into organic matter for your garden.
The bamboo cloths are also 100% biodegradable. As a general rule of thumb, any natural fibres like cotton, wool, bamboo, cellulose, hemp etc are compostable and will decompose into organic matter. Synthetic fibres such as polyester, nylon and acrylic will eventually break down (this will take many years, sometimes up to 200 years) but they break down into microplastics.
