Anywhere to donate new and/or used plastics?

As my collection of plastics grows, I've come to realize there are some plastics that I haven't touched in months. With more time on the water, I have a better idea of what works now, and what doesn't. I've been on a mission to reduce clutter, and as small as these extra plastics are, they are still clutter to me.

Is there anywhere that we can drop off old plastics? What about new plastics that I'll never use. The various sponsors have been very generous in donating them to the FTFF events, but for my type of fishing I know I'll never use some of them. I'd like to donate them to somewhere or someone that would use them.

How do you more experienced anglers here deal with this?

I do give some away and I do try to sell some online as there are some out there that will use them.  I did pour my own for awhile so I tried melting old plastics down and that did work.  Only issue is I have a tone I made and don't use LOL.
This is a good questions we need to know what to do with old plastics.
