Aluminium cans
Approximately 1 billion are produced in the USA each year. The first can was designed in 1958 by Kaiser Aluminium. This metal proved ideal as it was a lightweight, flexible material that allowed manufacturing of the bottom & sides of the can from a single sheet, leaving the top to be added after the can was filled.
The first cans were opened with a separate opener but this was inconvenient so Ermal Fraze designed a small lever attached to the can which was removed as the can was opened.
The design was workable but after a while it created an ethical dilemma:
in this case could cause injury on hands or feet when some body walk ,also it is cause more environmental
So in 1976 Daniel F. Cudzik invented a simple, stay-attached opener of the sort familiar today.
As improvements were made in the design & production of aluminium cans, various ethical problems arose concerning:
this new developments could make people to drink more soft drink which can make problem to thir healh
b. Environmental pollution:
many of people are dont care about environment which could they throw out the cans on the streets
c. Convenience:
the cans material type is difficulte to recycle it and which can make problem for municipality
d. Money:
the industy can take the used cans from the streets and everywhere and recycle it it will be cheaber than they made new cans
