EPA’s 12 Principles of Green Chemistry

OSS Extractor

Note

1)   Prevention YES No waste to treat/clean 2)   Atom economy N/A 3)   Less hazardous chem. synthesis N/A 4)   Designing safer chemicals YES Non-toxic extractor design 5)   Safer solvents and auxiliaries YES Solventless!! 6)   Design for energy efficiency YES Minimal energy use, no fume hoods, no

evaporators, no large quantities of hazmat materials to transport

7)   Use renewable feedstock YES Uses small amount of plastic and metal material that can be reused/recycled

8)   Reduce derivatives N/A 9)   Catalysis N/A 10)  Design for degradation N/A Uses small amounts of plastic and metal

materials that may be reused / recycled. 11)  Analyze in real time to prevent

pollution YES Analysis can be performed on-site and in real-

time, portable technology 12)  Inherently safer chemistry for

accident prevention YES No solvents or hazardous materials, safe analysis

process minimal potential of chemical accident
