What is RPP?

Polypropylene (PP) plastic is a form of hard plastic created out of refining petroleum, another scarce and valuable commodity extracted from the earth.

PP is one of the most used plastics in the world. But because PP is mixed with metals and other materials to make large domestic appliances such as refrigerators, washing machines and air conditioners, it is laborious and costly to separate the PP from the metal, leaving PP estimated at only 3% recycled.
