Similarly, both of the materials reached their lowesrt point in 1990. Subsequently, between 1994 and 2010 paper and cardboard decreased finished the perio at exactly 70 percent, meanwhile glass containers increased and end the period at 60 percent.
Furthermore, aliminium cans began the period at 0 percentage. Between 1986 and 2010 this rate saw a upward trend and end the period around 50, while plastics commenced the period in 1990. Throughout the next two decades, this level increased steadily and finished the period around 10 percentage.
