Use the waste packaging to craft stuff for your home and workplace. Start a forum/slack with makers interested in stuff like this and share ideas. You can probably build a lot of eco friendly solutions to your everyday problems with the high quality packaging.
This is an excellent idea! I often 'save' packaging from Amazon in case it comes in handy but honestly don't usually find a use for it. The best I've done is to reuse the thin packages as padding for devices in backpacks and cases when travelling.
