If you check the label of the garment you are wearing right now, there is a great chance that the fabric is vowed or knitted with a blend of different fibres, for example a mix of cotton and polyester. This is one of the biggest challenges when it comes to textile recycling, to find ways to separate fibre blends so the different fibres can be recycled in their different systems. A t-shirt composed by 99% cotton and 1% spandex cannot today be recycled, instead it often ends up as landfill or being burnt in a thermal power station.
This is why we at Tierra became interested in mono-materials, materials that only consist of one material or fibre, instead of a blend. It is easier to recycle a garment made out of one single material, as opposed to separating several materials and then recycle them separately.
