Precious metal recycling
We are a precious metals recycler with one of the largest recycling plants in Japan. In recent years, the handling of ethical jewelry has expanded, especially in Europe, and demand for sustainable materials has been growing rapidly. The same trend is spreading in Japan as more and more consumers seek to reduce their environmental impact, use resources responsibly, and promote respect for human rights and ethics.
New mining of precious metals requires a great deal of energy and emits large amounts of CO₂. For example, in the case of gold, recovery through recycling can reduce CO₂ emissions to about one-tenth of those from new mining. We promote precious metal recycling through advanced refining technologies and processes with low environmental impact, thereby contributing to the reduction of your company's carbon footprint.
