Common Threads Recycling ProgramResearch shows that the environmental impact of recycling worn-out Capilene base layers into new polyester fiber is significantly lower than making that same fiber from virgin materials. Taking into account that worn-out garments are diverted from trash incinerators, making new polyester fiber from recycled garments results in an energy savings of 76% and a CO2 emissions [greenhouse gasses] reduction of 71%, versus creating that fiber from new raw material.
