Not only for packagings, but also for other items, as long as they are made of the same materials
WHITE BIN: LIGHT MULTI-MATERIAL
WHAT YOU CAN PUT INSIDE THE BIN
In Italy 75% of the weight of the steel packagings on the market is recovered (almost 3 packagings out of 4). Moreover iron and steel can be re-used endlessly without loosing any of their properties.
Spray bottles with dangerous product symbols on the label must not be put into steel bins. Food leftovers have to be removed from the containers.
