12 Principles 12 Principles Prevention Prevent waste rather than treat it or clean it up Inherently Safer Chemistry for Accident Prevention
Reduce Waste Atom Economy Reduce Derivatives Use of Renewable Feedstocks
Reduce Hazards Less Hazardous Chemical Syntheses Designing Safer Chemicals (Minimizing Toxicity) Safer Solvents and Auxiliaries

Often not the “worst” chemicals, but critical due to the scale of the waste stream
Affects a large number of laboratories across the campus and has the potential to develop a broad support base

Strong support from faculty who would prefer an alternative
Safety and Sustainability motivationsHigh potential for no alternative to be
found, but important to ask the question
Great learning opportunity for student interns performing the research

Honors courses as a testing groundStep 1: Identify courses that use a
chemical you want to replace Step 2: Identify a potential alternative
(MIT Green Purchasing Wizard, great start)
Step 3: Test alternative in honors class and use the rest of the class as a control
