During a community clean up day, I scored about 400 pounds of plastics  ranging in thicknesses from 1/8" to 1" and in every color and finish imaginable.

A lot of the 1/4" 12" x 12" squares got used for router bases, but most sat around waiting for me to figure out what I wanted to do with it. I did buy the solvent to weld pieces and even a plastic bender (as well as made one from some nichrome wire I salvaged.  

After a while, I started laminating the 1/4" fluorescent pieces between wood, turning them, then adding copper plated turnings I made.

The hard part is finding glues that will do the job, because the plastic shifts far less than the wood does.  Even well dried wood-plastic laminates are problematic.  

Epoxy doesn't do well, unless there is a certain brand that will both soak into the wood and dissolve some of the plastic. That even after majorly grinding into the plastic, for adhesion purposes.

Interestingly, the "Superglue" approach seemed to hold the best.

Curious as to what you used.
