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 nylon yarn, 77,000 BTU's** are conserved, the equivalent of .6 gallons of gasoline.
