Abstract
Recently, the recycling of precious metals from scrap generated during manufacturing processes and from end-of-use products has encountered issues associated with environmental regulations. Furthermore, there is a continuous increase in the demand for precious-metal materials with better qualities. The initiatives undertaken by Matsuda Sangyo Co., Ltd. to overcome the abovementioned challenges are discussed in this paper. These initiatives include the development of high-quality sputtering target materials and the effective use of nitrogen-containing wastewater generated from recycling processes. Advanced recycling technologies for lithium-ion batteries are also introduced.
