Design, production & ethical issues

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 the consumer’s safety and the environment around them.to the consumers it can be hazards material, the discarded aluminum tabs on the top of the can, could easily led to bleeding or hurting your finger while opening, especially to the children. To environment, as it a sharp material a lot of people through it once they open it. 

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 aluminum tab is open to a atmospheric air so it can be exposed to any type of pollution around so there is a change to transfer any harm substance to the liquid inside. Moreover this top part is sharp it can injured easily to whom  doesn't used it properly 

b.     Environmental pollution:

Aluminum could easily be the poster child for recycling. Reusing scrap aluminum to produce new aluminum requires only 5 percent of the energy needed to extract aluminum from bauxite ore. However, aluminum recycling, technically referred to as secondary aluminum production, is not without its environmental problem

c.      Convenience:

Canned food very preferable to a lot of customers its cheaper and easy to carry and cooked. But normally the have long expiry date which a lot of people may worry of what they eat and how they stored 

d.     Money:

Aluminum is a type of metal that does not lose any of its properties when it is recycled. Due to this, it is okay to recycle aluminum over and over, which makes it a popular material for many goods. Many people are interested in the current aluminum can recycling price to see how much their cans can get them at the recycling center. This price fluctuates almost daily depending on supply and
