An analysis of future platinum resources, emissions and waste streams using a system dynamic model of its intentional and non-intentional flows and stocks

摘要: Abstract Platinum is increasingly used intentionally and non-intentionally in several applications. This has raised the concern about its future resources, emissions losses during life cycle. On one hand, increasing platinum might affect human health. other accumulated mineral waste, soil, landfill sites construction materials as a result of emissions, utilization secondary can be seen potential resources for platinum. paper aimed at (1) analyzing long term impacts use on demand supply, release to environment accumulation (2) quantifying amount that would available supply. The analysis carried out global level using system dynamic model intentional non-intentional flows stocks. based four scenarios introduction fuel cell vehicles (FCVs). results show overtime all different rates identified are expected deplete before end century with or without FCVs. soil decrease when conventional ICE replaced by time depleted more than double parts world. methodology presented this assessment technologies metals.
