Deakin researchers develop concrete solution for recycled glass | Deakin
some types of colored glass aren't recycled due to the difficulty in cleaning it up to clear again, so being able to use it elsewhere is a plus as an alternative to high grade sand. But this is polymer resin based concrete (substituting cement) so that's a different problem...

Revolutionary radiation-sensitive plastic (trademark "Scintirex") with a performance superior to plastic scintillators used for measuring radiation and enabling a major reduction in production costs : NIRS
Sintirex is a recycled PET plastic based plastic scintillator, which basically means the chunk of plastic glows in the dark if hit by radiation. So you put it in a sealed case with a simple optical sensor like a cheap CCD to make a crude but effective low cost radiation detector. Apparently it should be possible to make portable detectors that currently cost $500 for around $100 or less now.
