12 Principles of Green Chemistry

2. Maximise incorporation of materials

7. Use renewables

3. Lower toxicity

4. Design

safer chemicals

12. Accident prevention

11. Monitor

and analyse

1. Waste prevention better than clean-up

5. Don’t use solvents!

9. Use catalysis

8. No protecting group chemistry

6. Minimise energy

10. Design for degradation

“Natural” products are very desirable…they need to be:

- derived from natural resources

- extracted using “natural” solvents (H2O, EtOH, CO2)

- modified only be “natural” methods (biocatalysis)

“It is the first ever fully recyclable PET plastic beverage bottle made partially from plants. The material looks and functions just like traditional PET plastic, but has a lighter footprint on the planet and its scarce resources.”

“PepsiCo's "green" bottle is 100 percent recyclable and ... is made from bio-based raw materials, including switch grass, pine bark and corn husks. In the future, the company expects to broaden the renewable sources used to create the "green" bottle to include orange peels, potato peels, oat hulls and other agricultural by-products from its foods business”
