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.
For every 1 LB. of Repreve polyester yarn, 50,000 BTU's*** are conserved, the equivalent of .4 gallons of gasoline.
