Paper and cardboard packages are made of cellulose, so their recycling saves millions of trees every year. Cellulose fibre deteriorates after 4 recycling cycles, so by selective collection, the same material can be introduced in the economic circuit 4-5 times!
PET package. The abbreviation comes from polyethylene terephthalate, a polymer made of petroleum. Its properties make it extremely useful for packaging liquids, often replacing glass. The increasing quantities of PET used for packaging and its high resistance to the action of natural factors require the selective collection of this type of packaging waste.
