In the early 2000’s the Aluminium Industry tried to answer two global questions: How much aluminium scrap is recycled today and how much will be recycled in the future? How much primary aluminium will be produced in the future?
To answer these questions, the aluminium industry developed its first aluminium flow model in 2003 covering the year 1888 to 2030. It was built on industry data, expert knowledge, reviews of published literature and consensus views of product lifetimes and end-of-life product collection rates.
Today the two key questions have not changed but now also include where and in what quality scrap will be available, growing in-use stocks and resulting primary aluminium needs, as well as a modular view with regional differentiation in product lifetimes, power mixes, carbon footprints to build environmental scenarios.
