Peter,
The last question posed, in Rodney's extremely informative thread, went unanswered.
How do you deal with disposing of the waste created by the acid etching process?

I looked in your profile and you dont have anything in it. Where are you located?
I am in the midwest, about 5-6 days UPS ground shipping away from you. I am sure there are plenty of shops within one day shipping from you who can easily do a job like this. DGL could certainly do it and also Quality One Engravers does work like this.

Jim,
He is also 2-3 days away via priority mail..... and most likely at an "all you can fit" rate.

Good question.
a couple of ways.
1. You either decant the product into plastic drums and have a liquid waste management company dispose of it for you.
2. or you have a sophisticated waste liquid treatment plant incorporated into your production system.
Either way pricing the plates must take into consideration these costs.

You don't have a rotary, but the cutter I use is an EH-8 from Bruce Diamond. I have several different sizes of SS cutters. Other instructions, double passes, lubricate, clean good before paint filling, etc. are the same.
several have asked about this cutter ... here is the info from their website.
Awards and Recognition Association
Winner Best New Technology
The EH-8 Series – Long Lasting Cutters
Stainless – Brass – Aluminum – Plastic – Phenolic
The EH-8 Series represents the newest cutting tool technology. It offers vastly improved engraving performance plus increased tool longevity with tighter tolerances and cleaner cuts.
EH-8 Put to the Test
In a recent series of tests conducted for Bruce Diamond by an independent Master Engraver with over 40 years experience, the EH-8 was put through its paces by engraving a plaque of the Gettysburg Address on a piece of 304L stainless steel, one of the most difficult materials to engrave. The tool sailed through all 1,215 characters of 24-point type without resharpening! Typically, the best micrograin tool would need to be resharpened after 100 characters or less on 304L stainless.
Astounding success on other substrates
Additional tests were conducted on brass, aluminum, plastic and phenolic showing significant increases of at least 5 times greater longevity in tool life. It was also found that the quality of the work improved with better tolerances and cleaner cuts.
I have used these on 304 SS plates and do get a lot more mileage/letters out of them. I hate the mess/time of SS but love the $$. B-)

The co that supplys us the the Ferric takes the spent etch back. We just decant it into the containers it came in and they collect.
It seems to poses no ecological risk or toxicity according to this
http://wfldelearn.pssd.com/BinderView_PSS/vault/005/005325.pdf
Tho it does have recommendations as to disposal which probably vary from country to country.
I certainly wouldnt dump it down the drain or anything like that

Don't forget that if you've used the ferric to etch stainless that the ferric now contains a fair amount of chromium, since stainless has a high chromium content. Chomium is a toxic metal.EDITED: 5 Aug 2006 by DAVERJ

It seems that a firm known as Port Engravers in West Sacramento used to do
stainless a few years ago. In fact they were listed in the 2003 SBC Business to Business
