See the instructions in What to do before you sell, give away, trade in, or recycle your Mac - Apple Support
Note that you will skip the "Use Erase All Content and Settings" section and use the other sections instructions instead

Also if you're going to recycle the Mac you can skip the installation of the system - just sign out of all accounts and erase as the document says.
How do I erase an old iMac with High Sierra OS before disposal?
