Talking about "Green Chemistry" like this seems to imply it has limitations and is static...

Quiet the contrary - Green Chemistry looks to improve existing processes and industry in any beneficial way it can.

Biomimicry is an excellent idea - but is difficult to implement from scratch. You don't just design an artificial catalyst from scratch.... Science is only really beginning to scratch the surface... for example the use of supported-enzymes is a 1st generation of this idea. Still in very early stages of their development.

Much like many others of what encompasses "green chemistry"...

A better way of thinking about GC is to think of it as Applied-Chemistry

Indeed teaching it this way - integrated looking / researching industrial problems in integrated fashion - is an excellent way to learn multidisciplinary subjects (sciences economics sociology etc - "the three drivers")... and in the need for commercialisation of science it is a must! (Ask the UK Patent Office - I know I spoke with them a week ago on the subject!)

The impact of INFORMATICS on this developing subject - is a subject I am very interested in.

Good blog Joel.

PS.

"But as I said, it's all relative. Like the notion of "pollution prevention" itself, green chemistry typically promotes "less bad" ways of doing the same things, rather than rethinking the solutions altogether -- for example, a less-polluting alternative to a synthetic organic pesticide, as opposed to organic farming, which may obviate the need for the pesticide altogether."

Rewriting the book from the start - is near impossible and would take enormous sums of money and a long time...

It's better to rewrite the book a chapter at a time... then rewrite any sections with improvements as they arrise.


Plus, how can you be sure a replacement is actually better than the original... all the way "from cradle to grave"???

In GC theres a tool called LCA (as well as other forms of analysis also). These can be exhaustative and may take several years.

Look at Thalidamide - people thought that a good solution until one enantiomer molecule of it - caused birth defects.

For this reason - changes have to be thought out, measured and systematic.


It is not because Green Chemists - lack ambition!

It's because we're taught to be lateral thinkers!

Great post - very informative - I have heard talk of releasing gases into the upper atmosphere to reduce global warming... would this qualify as green chemistry? James @ Organic Development. We undertake Internet Marketing
