The speaker talking about recycling said, "i took a beer bottle to the recycling center, but they wouldn't take it. they said: this is the pint of no return." what humorous verbal strategy did the speaker engage in?

The humorous verbal strategy that the speaker engaged in is pun.
Pun is a play on words, meaning that you change words a bit in order to create a humorous effect. Here, the saying is "a point of no return," but the speaker was talking about beer and wanted to be funny, which is why he said "a pint of no return."
Hyperbole is exaggeration. Malapropism is a wrong usage of a word, often unintentional. Spoonerism refers to the change of initial letters of words only to create a humorous effect.
