Platinum and palladium are used in small but essential quantities in a variety of advanced industrial sectors. Platinum and palladium are used as catalysts in various industrial sectors, especially in the car industry. However, their sources are typically concentrated in South Africa and Russia, and there are concerns about supply security. In terms of resource security, it is important to verify domestic platinum and palladium consumption trends and future demand. In order to understand the domestic platinum and palladium consumption trends in Japan, we tracked the historical platinum and palladium consumption structures from 2001 to 2013, applying a bottom-up approach, and illustrated recent domestic platinum and palladium flow by using a substance flow analysis. The results showed that catalytic converters (9.1–12.8 t) and jewelry (5.3–15.5 t) for platinum, and catalytic converters (14.2–20.0 t) and dental use (9.5–16.4 t) for palladium, have marked the biggest consumption sectors during 2001–2013, where the total consumption of platinum and palladium have fluctuated by 18.4–31.6 t for platinum and from 33.0–46.3 t for palladium. We also forecasted the demand for each end-use of both up to the year 2025 using multiple regression analysis. Our results suggest that platinum demand could decrease from 18.9 t in 2013 to 11.9 t in 2025 and palladium demand could slightly decrease from 33.0 t in 2013 to 13.8 t in 2025. View Full-Text
