ALUMINIUM IN BUILDINGS - INVENTORY AND COLLECTION DURING DEMOLITION

摘要

The European Aluminium Association in Brussels and the Resources and Recycling Engineering Department of Delft University of Technology jointly investigated the inventory and collection of aluminium before and during demolition of residential and commercial buildings in six European countries: France, Germany, Italy, the Netherlands, Spain and the United Kingdom. In cooperation with local authorities and demolition companies buildings were selected. The inventory of aluminium is extremely low for buildings, commercial buildings have a content of around 0.5% and the content of residential buildings is below 0.1%. The collection rates during demolition are better than 92% caused by the contribution of larger aluminium objects found in commercial buildings. In total the inventory of 1500 apartments and houses has been measured of which around 700 are monitored during demolition. Large commercial projects have been monitored prior to and during demolition in London (Wembley Stadium), Milan (The Pirelli Cable Factory and offices), Madrid (BNP - Paribas Bank), Wuppertal (the Court House and offices) and Pau (Elf Acquitaine Headquarters). The collection rate established in this study is restricted to the collection of aluminium on the demolition site and does not include the recoveries established during processing, sorting, mechanical processing and smelting.
