In 2014 the global production of plastics amounted to 311
million Mg (PlasticsEurope, 2015); in particular, in the same year,
in Europe 59 million Mg of plastics were produced (PlasticsEurope,
2015), the high volume being the consequence of the growing
demand for plastics which in Europe is equal to 47.8 million Mg
annually (PlasticsEurope, 2015).
