Recycle Outdated apple products!

I have a few apple products that I've had for some years. I don't want to toss them in the trash but rather recycle them through the actual vendor. I have a total of 4 items. They still work and I have used them only to listen to music or have as a secondary when needed. Can i make a request to recycle them all or just do one big push. I have already wiped all items as well.
