Many manufacturers prefer plastic as a material for containers because it can be molded into many shapes.
But plastic is not very strong. It must be fused with glass
or steel for strength. It is also not very durable. Even the
strongest plastic can break under enough pressure. The
biggest disadvantage to using plastic is that it does not
decompose. While plastic can be recycled, doing so is
tedious and difficult. While it may be more expensive and
difficult to work with, aluminum is a much stronger
building material with far greater tensile strength. It
conducts electricity because it is metal. Best of all,
aluminum is very easy to recycle. Even if it is thrown away,
it decomposes much more quickly than most
manufacturing materials.
