Yarn Curbside Trash Yarn Cannot Be Recycled Yarn cannot be recycled, and it will get tangled up in machinery at recycling facilities. Ways to Reduce Buy Yarn Selectively Instead of buying yarn whenever you’re at a crafts store and happen to see something you would love to use someday, only buy it when you need it for a specific project. Stick to Natural Fibers Avoid synthetic fibers such as polyester and acrylic and stick to natural fibers such as cotton, wool and silk. Synthetic yarns shed plastic microfibers that don’t fully decompose, adding plastic pollution in our environment.
