• Topics covered included :– Green metrics, alternate solvents, water as a reaction media, microwaves, photochemistry, catalysis, green analytical chemistry.

– Less organic chemistry knowledge based.

– Drew heavily from presidential green chemistry award winning examples.

Student Voice

• “The green chemistry course offered at Worcester State opened my eyes to the idea that being “green” is not simply about cutting carbon emissions, cleaning up toxic waste, or recycling paper or plastic.”

• “The best thing about learning green chemistry is that it encouraged critical thinking – solving decades‐old problems in the most efficient and least destructive manner possible, while preserving resources and the environment, is no easy task, but is entirely achievable”

Computational Research• Carbon monoxide molecules have been known to form polymeric like‐

chains that consist of several molecules in length, with relative stabilities often referred to as polyketones.  Understanding the stability of these molecules can help to predict how easily these polymeric forms of carbon monoxide can exist in the atmosphere.

• Destruction of ozone by bromine nitrate (BrONO2). The Enthalpy of 

reaction (ΔHRXN

) will be calculated for the reaction of bromine nitrate with ozone.

The Thai Collaboration• Erika Kubota, a senior in industrial 

management at ChulalongkornUniversity in Bangkok, accepted an invitation for an academic exchange in the Fall.

• Worked with Dr Kerr researching ways to extract biodiesel from soybean oil using ferric chloride as a catalyst. Ferric chloride eliminates  the use of potassium hydroxide.

• This fall 4 more students will be joining us from Thailand. 

• Special  “Research Methods” course setup to facilitate exchange and green chemistry research

College‐wide sustainability efforts• Purchase of a biodiesel processor to 

convert waste cooking oil into fuel by fall of 2009.

• Single stream recycling since October 2006, to double recycling.

• Elimination of cafeteria trays and the installation of high efficiency valves, reducing hot water used in dishwashing by 166,000 gallons a year. 

• Every week since November 2008, 500 pounds of food waste has been diverted from the college’s solid waste stream to feed pigs at Sayebrook Farms in Holden, Massachusetts. 

• College purchasing now requires recycled content in paper products, trash bags, paper clips and staples

The Future

• Strengthen our environmental chemistry track.

• Target general chemistry and non major students.

• Organize college‐wide awareness events.

• Apply for more green chemistry related funding

• More independent research that is “green” oriented.

• New hires should have similar department values.
