Repreve conserves resources because it offsets the need to use newly refined crude oil. Oil refining is a complex industrial process that turns crude oil into a multitude of
petroleum-based products. Some of these products are then made into ingredients that go into synthetic fibers. Compared to making virgin synthetic fibers, Repreve also uses less energy and water, and produces fewer greenhouse gas emissions.
For every 1 lb. of Repreve polyester yarn, 23,000 BTU's* are conserved, equivalent to 0.20 gallons of gasoline.
