Indeed, every polymer has its own peculiarities and melting points that prevent a linear recycling process as opposed to homogeneous polymers. This is why mixed plastics are mainly used for energy recovery. Unfortunately though, in Italy, they are typically separated at source, as opposed to other European countries where this does not happen. In Italy, citizens are asked to comm...
