Clay is a natural green product that is a healthier alternative to plaster, cement, acrylic and lime plaster. The clay comes from non-toxic oxides and ocher mineral pigments, which reduces the amount of toxins that can be released into the air from other materials.
Cork is a sustainable product that is obtained from the bark of cork trees, without damaging the tree itself. About a third of the trunk is removed every nine years for its cork bark, and the tree then regenerates new bark. It's a great alternative to carpet or wall paneling, and it's much softer than standard hardwoods.
