Green-nano zero valent iron (G-nZVI)

I’m quite interested in patents and their possible impact on nanotechnology innovation so this item caught my attention. VeruTEK Technologies, Inc. just received notice of a patent allowance for the Green-nano zero valent iron (G-nZVI) product which was developed in collaboration with the US Environmental Protection Agency (EPA).

From the June 15, 2011 news item on Nanowerk,

The product is ideal for a broad range of remediation applications including treating produced water (wastewater) generated during oil and gas and other chemical production processes.

G-nZVI works more efficiently than conventional iron catalysts, significantly increasing the rate of oxidant activity and can be used under a wide range of conditions.  Unlike other catalysts which are typically sensitive to changes in pH, G-nZVI consistently delivers high performance over a wide pH range. G-nZVI is highly effective as an activator for VeruTEK’s patent-pending Surfactant-enhanced In Situ Chemical Oxidation (S-ISCO®) treatment of hydrocarbon and chlorinated solvent contamination. The product can also be used with conventional in situ chemical oxidation (ISCO) to improve the effectiveness of traditional remediation chemistry.

The EPA works with VeruTEK on a variety of projects, concentrating on new field-proven approaches to address difficult environmental issues. According to John Leazer, Director of the Sustainable Technology Division at EPA’s National Risk Management Research Laboratory in Cincinnati, “Patent awards are superb examples of what can be accomplished through collaborative research and development.” [emphases mine]

I have previously written about nano zero valent iron (nZVI) and site remediation in my March 30, 2011 posting which concerned a benchmarking study for nZVI and briefly in my March 4, 2010 posting (towards the end) where I summarized a Project on Emerging Nanotechnologies webcast (approximately 54 min.) on the topic.

As I understand it, the process (green or environmentally friendly) by which the nano zero valent iron is derived is the reason the VeruTek product has been awarded a patent and not because its remediation capabilities are superior to other nano zero valent iron products. From the VeruTEK’s G-nZVI product page,

GnZVI is a green synthesized nanoscale zero valent iron catalyst invented by VeruTEK and the US EPA. During the green synthesis process iron salts are exposed to naturally reductive plant material, the resultant nanoscale particles are coated in iron oxide and plant polyphenols which confer advantageous properties.  Research conducted by VeruTEK, the EPA and the University of Connecticut, published in peer reviewed journals, demonstrate the efficacy of the product and its unique chemical design.

So, in addition to being used to remove contamination, this product itself is manufactured in a relatively environmentally friendly fashion. Nice!

Of course, there’s a fair amount of discussion about how patenting impedes innovation. From Mike Masnick’s Feb. 17, 2011 article on Techdirt,

As with any “hot” technology area, it doesn’t take long for a massive, innovation hindering patent thicket to spring up. It effectively makes it impossible to bring anything to market unless you’ve got a huge patent portfolio yourself and deep pockets. Yet another example of patents harming the smaller players in the market. A new report is suggesting that the latest “hot” area to get patent crazy is nanotechnology.

However, the really worrying thing about the report is that it notes that the single largest “patent patron” in nanotechnology… is the federal government. [emphasis mine]

The report, The Big Downturn; Nanogeopolitics, that Masnick is referring to is from The ETC Group who released it on Dec. 17, 2010 so the material in it is relatively recent. They provide the only overview of the nanotechnology patent scene (Chapter 12, p. 43 PDF version and p. 36 print version) that I’ve come across so far. I find the reference to the federal government (US in this case) as being the largest patent patron interesting in light of the EPA’s collaborative relationship with VeruTEK.

One comment before you rush off to read The ETC Group’s report, the tone is very much ‘we are on the side of the angels; capitalists and governments and ‘anyone who disagrees with us in any way’ are not.”
