So my family has a few containers of unused blank dvds that are just lying around collecting dust. i know dvds are almost useless because of streaming, but can they still be used. Theses dvds can only be written to once and they only have like 3 gb of storage on them, can they still be used?, do they have a use?

You will need to double check the specific DVDs you are working with. They can be useful for backups and if you don't store them in sunlight or acid or something they basically last forever. You can copy your important data onto a DVD and leave it in your closet for the rest of your life. Of course, as with all backup strategies, you need to test it very regularly.

Edited to add nitpicks: if you decide to do this back up across multiple DVDs and use encryption. Borg is a fantastic tool for encrypted backups and if you are just mounting your DVDs as cdrom0 and such it can handle that as easily as any other block device.

Not really. After a few years you'll get bitflips, after about ten the organic material will have decomposed to the point you can't trust the backup anymore. It's probably easier to use old HDDs for that which you periodically checksum.
