Waste sorting A help for life!
2
Waste sorting is a way to separate urban solid
waste.
3
  • The composition of rubbish is difficult to
    establish, because it changes from an area to
    another and depends on the economic and cultural
    level of its citizens but also on the industrial
    production of the place.

4
  • A typical container for the waste sorting is the
    so-called bell due to its shape. It is usually
    used for the separation of glass and plastic.

  • In many towns an incentive is applied for people
    who practice the waste sorting. In fact the
    principle of more you pollute, more you have to
    pay is applied, and it means that more you
    recycle and more you spare money.
