Bi-metallic beer cans
Because New Zealand beer cans were made of two metals—iron and aluminium —it was impossible to recycle them, the executive of Ecology Action (Christchurch) said.
By continuing to use such beer cans, New Zealand was wasting non-renewable resources. The executive was commenting on a statement by the chairman of New Zealand Breweries, Ltd (Sir Clifford Plimmer) that beer cans were not a major contributing factor to ecology problems in New Zealand.
“New Zealand beer cans are made of bi-metallic aluminium and iron. When the cans are discarded, the iron is lost from industry and the aluminium cannot be degraded into the soil. “Even if machinery capable of recycling the cans was present in New Zealand, the bi-metallic form of these beer cans would prevent this process.”
"rite executive said that alternative and recyclable forms of cans could be used.
