Abstract: The present disclosure relates to mineral wool compositions and articles, as well as methods for manufacturing mineral wool compositions and articles.

Abstract: 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.

Abstract: A method of recycling a composite material which comprises a mineral portion maintained within a thermoset resin, wherein the thermoset resin makes up at least 30 wt % of the composite material; and wherein the mineral portion makes up at least 30 wt % of the composite material comprises: introducing the composite material in granulated form into a mineral melt in a submerged combustion melter; providing additional heat energy to the mineral melt by combustion of the thermoset resin of the composite material within the mineral melt; and melting and incorporating the mineral portion of the composite material in the mineral melt by heat transfer from the mineral melt.

Abstract: A method of making mineral wool fibers comprising: 30 to 55 wt %; SiO2, and 10 to 30 wt % Al2O3, and 4 to 14 wt % total iron expressed as Fe2O3, and either a) 20 to 35 wt % of the combination of CaO and MgO; and less than 8 wt % of the combination of Na2O and K2O; or b) 8 to 23 wt % of the combination of CaO and MgO; and 4 to 24 wt % of the combination of Na2O and K2O; comprises introducing mineral batch materials in to a melter, melting the mineral batch materials to provide a melt and fiberizing the melt to form the mineral wool fibers. The mineral batch materials introduced in to the melter comprise a first batch material comprising: 52 to 68 wt % SiO2, notably 52 to 62 wt % SiO2, and 12 to 30 wt % Al2O3, notably 12 to 16 wt % Al2O3, and 0 to 25 wt % CaO, notably 16 to 25 wt % CaO, and 0 to 12 wt % MgO, notably 0 to 5 wt % MgO, and 0 to 10 wt % B2O3, notably 0 to 2 wt % B2O3, and 0 to 2 wt % of the combination of Li2O+Na2O+K2O, and 0 to 1.5 wt % TiO2, and 0.
