I am not sure this is the correct place to post this (related) question, but I was wondering if anyone had ideas regarding the recycling of large amounts of test tubes.

I am a student at a university in which many thousands of test tubes and other small pieces of glass (e.g., microscope slide coverslips) are thrown out every day. I have been told that the pieces are themselves so inexpensive that it would cost more to clean and reuse them than it does to simply throw them out.

However, I feel that there must be some use for these thousands of test tubes. Does anyone have any ideas here on what to do? It is possible that, if a good idea is suggested, funding of several thousand dollars will be available.

Thanks,
Andrew

Now use the tube stand as a rooting
station for various plants such
as Ivy. When they have taken root,
which you can easily see in the tubes,
simply transplant them. When the water
level decreases, simply fill the tubes
back up.

I often use this board when spring approaches, to make additional shoots of Sweet Potato.

You can also try and find some cork for them and store your spices in them – you can even put them on the kitchen wall in the same fashion as described above

There made of a jelly type plastic and have a sucker on the end to attact them to most surfaces. your suppsosed to use them for the heater in a fish tank.
