Eco-Friendly Source of Cork Flooring Explained

Cork flooring is gaining popularity among homeowners and designers for its natural beauty, comfort underfoot, and most importantly—its sustainability. But what makes cork such an eco-friendly flooring option? In this post, we’ll explore the origins of cork, how it’s harvested, and why it’s one of the greenest flooring materials on the market today.

Where Does Cork Come From?

Cork is harvested from the bark of the Quercus suber, commonly known as the cork oak tree. These trees are native to the Mediterranean region, particularly Portugal, Spain, and parts of North Africa. Portugal alone produces over 50% of the world’s cork supply.

What makes cork unique is that the bark can be harvested without cutting down the tree. In fact, cork oak trees can live for over 200 years and be harvested every 9–12 years after reaching maturity. This process makes cork a renewable and regenerative resource.

How Cork Is Harvested

The harvesting process is done by hand using traditional tools to carefully strip the bark without harming the tree. The first harvest, known as “virgin cork,” occurs when the tree is about 25 years old. Subsequent harvests produce higher-quality cork used in flooring, wine stoppers, and insulation.

After harvesting, the bark is dried, boiled, and processed into sheets or granules. For flooring, cork is often ground and compressed with eco-friendly binders to form durable planks or tiles.

Why Cork Flooring Is Eco-Friendly

Renewable: No trees are cut down during harvesting.
Biodegradable: Cork naturally decomposes at the end of its life cycle.
Low VOC: Most cork flooring products emit little to no volatile organic compounds.
Carbon Sequestration: Cork oak forests absorb large amounts of CO₂, helping combat climate change.
Recyclable: Cork flooring can be recycled or repurposed after use.
