Eunah just passed her generals!

Katja's recently received the Waldbridge Fund Graduate Award to pursue "Stable Isotopes Studies to Evaluate the Biogeochemical Role of Methane Production by Nitrogenase" 

Congrats to both!

Five projects will explore sustainability using the Princeton campus as a laboratory

Building better compost

A team of researchers will work with Princeton’s on-campus composting facility to explore conditions for creating high-quality compost that is high in nutrients and low in greenhouse gas emissions. The facility, known as the Sustainable Composting Research at Princeton (S.C.R.A.P.) Lab, houses a biodigester that converts campus food scraps into nutrient-rich plant food, helping to divert food waste from landfills and reduce reliance on chemical fertilizers. The biodigester consists of a large barrel that rotates to mix air with food waste and a carbon source — such as wood chips or cardboard — to aerobically decompose the materials into compost in just five days.

The team, which will include an undergraduate researcher and be led by Xinning Zhang, assistant professor of geosciences and the Princeton Environmental Institute, will test various proportions of food waste, carbon inputs and air as well as operating conditions to identify conditions that create compost with superior levels of nutrients while reducing the natural emission of greenhouse gases due to biodegradation of compostable materials. The team will also explore the use of waste cardboard from the campus to replace wood chips.
