I've got a paper shredder (not one of the cheap ones) where the plastic
casing around the blades has been broken by the pressure of the paper etc. I
have tried to glue(with super glue) it back together but the joint keeps
breaking even after letting the glue dry for 24 hours.



Any recommended glues / reinforcing I could try. I did try to stick on
plastic reinforcing, but the glue did not hold

You'll never get an adhesive that's strong enough to last forever.
Depending what type of plastic it is (I'd guess polycarbonate, since
you say it's not a cheap shredder, in which case you're screwed) you
may be able to get something like "Plasweld" from a model shop. This
is just some solvent. You apply this to one side of the break, it
dissolves the plastic, then you apply pressure until the solvent has
evaporated. However it's unlikely this will last forever.

Your best bet would be to screw a metal plate across the break. Use a
couple of M2.5 screws/nuts on each side of the break into a suitably
sized piece of Ali. sheet. It won't be a pretty fix (more like
Frankenstein's monster), but you can bask in the knowledge that fixing
an appliance is much more ecologically sound that replacing it.
