Cork

Cork is a natural bark, harvested in Portugal from the regenerative bark of cork oak trees allowing them to live up to 200 years or more, which stripped of their bark absorb and store larger amounts of CO₂ and release more O₂, that means a healthier planet. Cork forests help support biodiversity among forests habitats and provides a source of income for over 130,000 people.

Cork is a natural material, and as such is fully compostable. If you don't have a garden, check your local garbage policy for wood.
