Aluminium in-use stocks in the state of Connecticut

The in-use stock of aluminium in the State of Connecticut, USA, has been established by an extensive “bottom-up” study. For year 2000, the results are a total stock of 1.2–1.4 Tg Al, or 360–400 kg Al per capita. The per capita stock amount is similar to that derived in a recent study in Japan. Infrastructure & buildings contains nearly 60% of the total stock, and transportation vehicles nearly 40%. The aluminium in equipment of various kinds amounts to only about 2% of the total, and packaging stock is less than 1%.
