In the sustainability plan, the brand states that they are in transition to more nature-friendly materials. They list some of those materials.
For example, they name Seawool, a circular material similar to wool made from plastic bottles and oyster shells. They use recycled polyester, of which some suppliers have a GRS ‘Global Recycle Standard for Recycled Polyester’ or COC, on ‘Eco Circle Recycled Polyester Fiber’ certificate. We can also see Ecovero Lenzing Viscose, which is made from wood pulp from sustainable sources and is better for the environment than normal viscose. They have clothes made from linen, a material made from flax that needs less water and chemicals than many other natural fibres, and we also find organic cotton.
In reality, these materials are not (yet) used much for Coster Copenhagen clothes and if they are used, they are usually mixed with another material. The brand has few garments made from mono materials, which means that the composition of fabrics often consists of different types of textile fibres. Not all polyester is recycled and not all cotton is organic. Besides Seawool, we also find animal wools in jumpers, such as alpaca and sheep wool.
