I have a crosscut shredder at home that can shred paper and credit cards. Wife didn't like me to shred plastic in it though, because she wanted the paper bits for the compost bin. Then when she realized not every kind of paper was good for compost either, she gave up on that.
The SOS includes a scanner
and spectrographic analyzer at the feed slot. It can distringuish paper from plastic, as well paper type and ink. It then shunts each type of material to a different cutter and output bin. For example, plastic goes into one bin, glossy paper into another, non-glossy paper printed with non-toxic ink into another, and so on.
It also can to detect and prevent shreddng of fingers or neckties. This safety feature may be disabled by the factory for a small fee, with no explanations required as to why you want such a thng.

After a few ... unfortunate incidents ... the company decided to modify that fee structure. Finger & necktie detection can still be disabled for a small fee, but the buyer must sign an acknowledgement that they requested it. |

| |
The "no questions asked" option is still available though - for a much larger fee that must be paid in cash. |

Would it be possible to sort the paper fragments by use of a fan? I.e. if all the paper fragments are the same size, they will be different weights, and a fan which blows them to the side will effectively sort them by weight, each fragment landing in its own labelled bin (from 'tissue paper' to 'depleted uranium') |

[hippo], that's a definite maybe. According the linked article on recycling sorting machines, "blowing air can separate lighter paper and cardboard from heavier objects such as glass bottles and metal cans." But I don't know if that can be tuned finely enough to separate different types of paper. |
|
| |
And even if it did ... what would I do with all the scanners and spectrographic analyzers already acquired for this project? |
|
| |
Why a small fee? I would let the going rate on the market for such activities determine the price, which I hear, in the right part of town, is substantial. |

Our local recycling plant uses similar techniques to sort mixed recycling - fans to separate paper and card, inductance loops and magnets to separate non-ferrous and ferrous metals, and different salinities of water to separate different types of shredded plastic and glass.
