Disposing used cartridges

Has anyone ever had any problems disposing used dialysis cartridges?
I know the sharps/blunts can go in a taped sharps container but have any disposal companies raised a stink about the used cartridges?

Not here, the whole circuit (Lines/Dialysers/Bicarts etc) gets collected by the local authorites via a special clinical waste collection. As do the sharps bins. We recycle some of the non contaminated paper/plastic/ cardboard packaging

I’d suggest that you ask your home training nurse. You may have been home trained prior to 10/14/2008, when the new dialysis regulations took effect. The regulations require that training for home dialysis include information on proper waste storage and disposal procedures, including ensuring that patients understand their local waste management rules.
