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:
The ethical dilemma here is, this small lever could injure the consumer and cause bleeding, other aspect is every consumer after opening the can will throw out this small lever. This will cause environmental pollution.
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:
a.
Human safety: the new developments encouraged people to buy and
drink soft drinks, and these soft drinks are considering unhealthy for humans
bones.
b. Environmental pollution: the more
consumption the more pollution will be. Because there is a big majority of
people are not caring about environmental issues, so they throwing cans in the
surrounding environment. These cans need long period of years to be
degraded.
c. Convenience: aluminum cans recycling need a lot of energy
to melt it and remade it again. This big amount of energy will have a bad
effect on the global warming.
d. Money:
Aluminum cans industry is profitable business if everyone recycles
the aluminum. The consumer can send the empty cans to the recycling factories
and will get money for it. Also the factory will benefit from recycling process, no need to have ore aluminum in big
quantity.
