In the leather industry, the wastes after the wet blue phase, which are created by the shaving process, are one of the substances that cause environmental pollution. Most of the time, these wastes are buried and may, under some circumstances, cause serious environmental pollution problems. In this study, the chromium in wet blue shaved waste is to be minimized by using oyster mushrooms (Pleurotus ostreatus). Wet blue shaved wastes were mixed with 0.5%, 1%, 1.5% and 2% doses into the growth medium. After the oyster mushroom growth, the consumption of chromium from the growth media and uptaken by the mushrooms were investigated with Ege University Argefar Lab.'s House Method using a ICP-MS.
