Mineral wool fibers having a mineral wool fiber composition are manufactured by introducing batch materials into a melter, melting the mineral batch materials in the melter to provide a melt and fiberizing the melt to form the mineral wool fibers. The batch materials comprise i) fibers having a first batch material composition which is different from the mineral wool fiber composition and consisting of scrap fibers which have broken at a bushing producing continuous fibers; and ii) one of more additional mineral batch materials.
