There have been developed some processes to spin yarns form leftover materials, including discarded coffee grounds; coffee is milled and mixed with recycled Polyester or Nylon 6 and the material is then melted and spinned to obtain yarns.
Also, sneakers can be developed featuring a coffee-based textile, by processing and mixing coffee grounds with recycled plastic pellets to create a polymer thread.
There have also been developed some fabrics made from recycled coffee grounds and recycled plastic.
Utilizing coffee ground yarns as an alternative to leather can helps reducing the demand for animal-derived materials and contributing to the development of more sustainable fashion and textile industries.
