Hello Ralph,
I will send you selections from our Laboratory SOP where I have initiated such procedures if you like..
The financial, legal and ethical benefits from neutralization far out weighs any down side.

Much literature alludes to reducing hazardous waste generation from a chemical procedure by including a step or steps within the procedure to accomplish the reduction of "end-of-the-pipe" hazardous waste. Can anyone provide me with an experimental or instructional protocol that serves as an example of this concept?

A document from Battelle mentioned neutralization, separation, fixation, oxidation, precipitation, degradation and ion exchange.

I'm looking for examples of laboratory procedures into which these or other steps are incorporated specifically to reduce waste/hazardous waste generation. I'd especially like to see examples of things other than neutralization.
