Replying to Honest Question: What to w/ beat old ski boots?

Hi all, I have had my old full tilts sitting in my closet and not in the trash can yet because I couldn't help but wonder if there is somewhere to take ski boots where they can be recycled. I get that the liner is probably just trash but I feel like that amount of plastic is kind of a ridiculous amount to just straight up throw away. Anyone know anything about this? Was just gonna pull up to a ski shop and find out but I guess I felt like asking here first.
