Are these cups recyclable? If so, how do I sort them?

My husband won't drink out of our ceramic cups or any other brand. He says his coffee stays hot longer and when he is done cleanup is easy

Coffee does not stay warm in these cups and after 45 minutes it starts to seep through the bottom of the cup as shown in the picture.

i use these cups for my coffee in morning an the new style makes my coffee leak after maybe 45 minutes of sitting there

Love them very much.use them all the time.especially on holidays.
