Clean out, how and where to put the stuff?

Hello,

Due to an upcoming move, I have a lot of decluttering to do in my apartment. You know those drawers you never open, where everything is just inside, but you don't need any of it? How can I dispose of it? Do I have to separate all this stuff? We have a recycling center where I could possibly take it to the general waste, but how do I pack it? In a bag? It's a mixed bag, and it would take me a lot of time to separate everything. I've already sold some things, etc. Maybe someone knows something or has an idea (and I don't have the money for a container, and we don't have bulky waste).

thanks in advance
