A method for recycling HSS processing process waste comprises: a pre-treatment step of pre-treating the HSS processing process waste; a primary melting step of forming a primary melt by primarily melting, at a temperature of 1500-2500 degrees Celsius (ยฐC), the pre-treated HSS processing process waste and at least one from among ferromolybdenum, ferrotungsten, and ferrocobalt; and a manufacturing step of manufacturing a HSS master alloy by performing ingot casting of the primary melt. The pre-treatment step comprises: a separation step of separating the HSS processing process waste according to the composition; and a mixing step of forming a mixture by mixing the separated HSS processing process waste and an oxide including at least one from among K2O, CaO, MgO, SiO2, Al2O3, and Fe2O3, wherein the melting point of the mixture is 800ยฐC to 1700ยฐC.
