Rotary hearth furnace for steel solid waste recycling: Mathematical modeling and surrogate-based optimization using industrial-scale yearly operational data

Economic Feasibility Evaluation of Bioleaching-Based Tungsten Recycling of Semiconductor Industry Waste

“…In the context of the escalating global industrial demand for rare metals, the recovery of metal resources from industrial waste or E-waste is paramount for fostering a sustainable society. This necessity aligns with the principles of green chemical engineering and is driven by considerations of global warming and environmental impacts. − Notably, wastewater generated from semiconductor manufacturing processes contains environmentally hazardous materials, such as tungsten, fluorine, copper, cadmium, and lead. The development of technologies to recover metal resources from wastewater in semiconductor manufacturing is gaining attention as a solution to environmental pollution and resource depletion issues. − Tungsten, recognized for its essential metallic properties, is widely employed in various sectors.…”
