Recycling processes have gained great importance for both environmental and economic sustainability and_x000D_ development. A prototype system was developed using physical separations including size sieving and magnetic_x000D_ separation for the recycling of solid die soaps used as lubricants in industrial wire drawing processes. The chemical_x000D_ composition of the waste obtained after the wire drawing process was elucidated by using X-ray fluorescence (XRF)_x000D_ analysis and extraction methods. The results showed that there was 67% reusable soap in the waste, and most of the_x000D_ remaining waste was made up of metals. Parameters such as particle size, sieve pore diameters, shaking time and_x000D_ magnetic field strength were optimized and an industrial scale prototype recycling system was designed. Finally, a_x000D_ prototype recovery system was established. Scanning electron microscopy (SEM), light microscopy,_x000D_ thermogravimetric/differential thermal analyzes (TGA/DTA), X-ray fluorescence spectroscopy (XRF) and Fourier_x000D_ transform infrared spectroscopy (FTIR) were used for the characterization. 88% of the soap in the waste was_x000D_ recovered, and the soap obtained was successfully used in wire drawing process without causing any deformation in_x000D_ the wire. These findings clearly demonstrate that offered system design engineered solution has a great potential to_x000D_ become a way out point for the waste recycling gain in the recovery and reuse of lubricant powder.
