Zena Green (a company registered in the Register of Environmental Managers) is the technical partner and promoter of PlasTiPremia, the project of AMIU and the Ligurian Institute for Consumption for the city of Genoa.

It deals with the selected collection of PET [Polyethylene terephthalate (drink and food containers)] and HDPE [high density polyethylene (detergents, soaps, shampoos, etc.)] bottles placed in dedicated eco-collectors. The collected material is then delivered to Amiu at the Sardorella plant (Bolzaneto) for correct disposal and subsequently recycled.
