Title: PLASTICS MILK CONTAINER


1
PLASTICS(MILK CONTAINER)
2
What is plastic made of?
  • Made from petroleum
  • Petroleum is made of plant and animal materials,
    it decomposes, sinks into the earth. Because of
    the pressure and temperature, it becomes oil.

3
How petroleum becomes plastic and plastic becomes
a milk container.
  • The oils and natural gases are heated in a
    cracking process (converts oil) and then there
    is a chemical reaction. This results in
    plasticall you have to do is cool it now. It has
    a lot of properties and characteristics.
  • The plastic, in its bendable form, is placed into
    a mold and injection-molded into its shape.

4
Alternate to plastic
  • You can turn paper mill waste into levulinic acid
    and this in turn can be made into useful things.
    Technology will be expanded to produce levulinic
    acid from other organic wastes, such as straw, so
    it can produce other chemical products, such as
    solvents, herbicides and plastics

5
How to recycle plastic
  • You put the containers in the recycling bin and
    then they take it to a factory.
  • They sort the plastics and then melt them.
  • They know have plastic again and they can bend it
    and shape it into other useful things.
