In the first year of operation of the grey containers, designed mainly for the collection of empty beverage cans, Prague residents sorted over 91 tonnes of metal packaging. People sorted the most cans this June, 13.36 tonnes. Radim Mana, spokesman for Prague Services, said. The collection of metal packaging started last August and now there are 456 grey containers on the streets of the capital. The containers do not include metal packaging from sprays or chemicals. The cans are taken by Prague Services to its premises, where the contents are sorted into metals and aluminium. After sorting, the aluminium is melted, cast and rolled into aluminium sheet.
