you need many things a hyperspectral camera to detect different materials, a database to have all the spectral information to check against and a nir sensor to detect other plastics that the camera can not read like black plastics. Look at how the large companies recycle using this method.

A good starting point is to know the 3 or 4 main types of plastic, and to distinguish between them
HDPE: is somewhat soft, but still quite tough, it is commonly found in objects like pill botles
PP: has similar characteristics to HDPE, and can primarily be distinguished by the number 5 with three arrows around it
PET: Very hard and transparent, it is primarily used in water bottles. BUT it is rather difficult to work with, as the temperatures needed for melting it are quite high, and very specific.
There is also PVC, which is used in things like sewer pipe, i would steer clear of this however, as it contains chlorine, which could be released if treated improperly.

And on today’s totally unrelated (in this case not so) fun fact, containers full of chlorine was used as an early chemical weapon during world war 1 by the germans with the slight downside that if the winds would change, the chlorine gas cloud would hit the germans instead.
