Where can i recycle epson picturemate photo cartridges?

I have a number of used cartridges from an epson picturemate photo printer that I%26#039;d like to keep out of the landfill. Any ideas on where I can recycle them? I don%26#039;t need to sell them, just find them a good home.|||Staples and Office Depot accept used ink cartridges. For other options: http://www.castleink.com/_a-recycle-ink-鈥?/a>
