Destruction of Cyanide

09/24/2007 5:45 PM

I manufacture a product that is used for calcium carbonate scale inhibition in water.

The European Community, through their EN Standards, is demanding that I test for Cyanide compounds in the product before I can sell it in Europe. This test is expensive in that I make over five hundred batches per year and each test costs up to $250 USD. It simply is not cost effective to do that testing, but I would like to sell into EU as my product is far superior to what is currently offered.

I contend that at the temperatures required (1700F min) to make the product, cyanide or any of it's salts can not exist. The furnace is fired by natural gas and the materials that make the product contain traces of water. Considerable amounts of water are driven off the solution during the firing and would further help in the destruction of any HCN or salts. I understand the HCN bond is very weak and dissociates easily. There is no potassium to form KCN. All materials are Food grade or USP grade.

Am I off base here or are they unreasonable?

Can the batch size be increased so that the fewer test costs required are spread more effectively?

No, the batch size can not be changed.

It is REACH Directive. While we may say that it is off base, the recent events in china give pause to our plaintive whine. Just consider it to be an inflationary cost of doing business in china.

REACH

What is REACH ?

REACH is a new European Community Regulation on chemicals and their safe use (EC 1907/2006). It deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The new law entered into force on 1 June 2007.

You are unlikely to out argue europes full corps of Green Bureaucrats.

We already have two NSF International certifications, EU RoHS certification, USDA, and pass all USEPA standards for hazardous materials in drinking water. Sb,As,Cd, Cr,Pb,Hg,Ni,Se, Mo, etc, are all non-detectable at the release rate of the product.

And I totally understand about Chinese products. We do not/will not use them even if the products cost more.

I know that arguing with the EU Greenies is a losing battle. It is totally unreasonable that the EU will not accept USEPA test methods for some of these procedures. A residual of .5 ppb or less of those metals is SO MUCH SMALLER THAN THE AMOUNTS ALLOWED IN THE TAP WATER.

The question still is: Will Cyanide survive the process? I do not think so. If someone could show me how it could, I'd be a happy camper.

Well I can look up the high temperature properties of KCN at work tomorrow;

After the 1700+ temperature excursion, what can you show the compound to have dissociated to? Send me by direct email (click on my name above) with list of all chemical species in this process at temperatiure and I'll look for them too.

My approach would be to 30 tests, and use student t distribution to give thwm an error band, Mean, and standrd deviation, but then again i m a rational empirical trained in science guy; they remain touchie feelie fearful greenie bureaucrats.

30 tests and statistical relevance is cheaper than testing each batch for ever and ever.

I will send you the name of a law firm that specializes in REACH issues tomorrow if you like.

Thanks anyway. I think I'll just let the Europeans continue to drink scale inhibitors that don't meet the specs required because they are made in the EU. I know they don't pass because we have had them tested for those metals and other impurities.

Well, they will have to deal with it, themselves, the REACH regs don't apply only to imports.

Some facts about reach.....NO-ONE Knows how this is going to work yet, least of all the enforcement bodies. It's going to be run out of an office in Finland (I think!) and they are going to rely on companies and/or organisations to report to them what substances they are importing/using. When they have enough information from all those co-operative....errrr...entities, they will then start making decisions.

As you can see, this is the usual well thought out and organised EU legislation. So, you could be breaking the law, you could go to the authorities and prove to them that you are breaking the law, and they still couldn't take any action, because no-one knows how to apply the law.

You couldn't make it up!

Makes you really want to do business there doesn't it?
