Jeremy Faludi in WorldChanging:
You can’t do green design without green materials, and material innovations tend to come from chemists. Chemists also produce many products in their own right: paints, adhesives, cleaning products, whole industries. So what are chemists doing to save the world?
For a less technical introduction, they have a web page listing their Twelve Principles of Green Chemistry:
1. Prevent waste
2. Design safer chemicals and products
3. Design less hazardous chemical syntheses
4. Use renewable feedstocks
5. Use catalysts, not stoichiometric reagents
6. Avoid chemical derivatives
7. Maximize atom economy
8. Use safer solvents and reaction conditions:
9. Increase energy efficiency
10. Design chemicals and products to degrade after use
11. Analyze in real time to prevent pollution
12. Minimize the potential for accidents
Most of these principles are aimed at being less bad. Michael Braungart argues convincingly that we need to shoot higher than that, we need to aim to be good. Zero is not a positive outcome. But some of them are positive goals, and for those that aren’t, even if less-bad is as good as we can do for now, we need to keep a longer-term positive goal in mind.
