Greener Screenprinting

I'm curious what kinds of tricks and products other printers are using to reduce waste and limit the use of harsh chemicals. In essence, how can we be more environmentally responsible and make the shop a more pleasant, healthy place to work?

A few things I do/ have done:

I save all my packing slips from incoming goods and when I have a healthy stack, I quarter them up with a paper cutter and use the blank side for in-house notes (saves on post-its)

Your local "sell your junk on ebay" store would probabley love to take your extra boxes and packing materials (mine did)

I only use spray adhesive (nasty stuff) on sweatshirts with a lot of fuzz inside. For everything else I use a double sided adhesive paper that cleans up with warm water and orange oil spray! This stuff lasts forever and works like a charm!

Scrap T's can only handle so many test prints and after that they don't make very good rags- but they do make good waste basket liners, especially if you use tape on your screens.

and so on...

Please share your greener printing tips.
