Need Help 20|20 Ink Empties

Don't quite consider myself a "newbie," but new-ish to using the 20|20 Ecosolv Max inks on our Roland, purchasing through Gimco. For reasons I cannot explain, we can't find anyone to take the empties. Grimco says our "local toner/ink recycler," and I'm not sure what they mean by that but e-waste won't take them, nor will places that take ink/toner cartridges like staples and officemax. (Not that we expected them to.) Places that took our old Roland cartridge empties won't take them because they're not Roland. "Home Hazardous Waste" would take them if I wasn't a business. I'm really at a loss. May have to do with being in beautiful California in the SF Bay Area, but I'm happy to ship if necessary, just need to get these things gone.

What am I missing?

 

Yup--that is the sitch. Thanks for the response.
