Does the word "recycle" a compound word of the prefix "re-" and "cycle"? And what would you call things that can't be recycled?

Absolutely! You are spot on here. To recycle something means to bring it back into the cycle of consumption. Things that cannot be recycled are simply called "non-recyclable" or "trash/waste/garbage." Ex: You can throw your non-recyclables [non-recyclable items] in this trash bin here. Ex: Remember to separate the recyclables from the garbage.
