Resin identification code
The code below is called the SPI resin identification coding system, developed by the Amercian Society of the Plastics Industry in 1988.
Most plastics can be recycled, but because of difficulty sorting, collecting and cleaning and reprocessing its only at the moement economically viable to recycle PETE, PVC and HDPE.
Thermoplastics can be remelted, but Thermosetting plastics can only be crushed and used as insulation.
As you can not mix plastics together they have to be separated into their diffrent polymer types.
