If regular air is being inserted through the compressor into the tubing, stored and used to move a piston, then released out into the atmosphere, isn't it just the same air it was when it went in? Why would it be considered hazardous waste?

And I would like to know if team could and would post a diagram of a simple closed air system (or explain in Great detail) to feed compressed air back into a system instead of releasing it and losing air pressure. Our team never really got around to creating a sub pneumatics team. It's always been just Electrical, Programming, and Mechanical.

I would assume a second lower pressure system would be needed to feed into, but I don't know how to feed it back into the higher pressure system, or to keep them unequalized, or the effect a 60 - 40 PSI co-system would have on power to the cylinders we are using.
