I was part of a team, along with Washington State University, that analyzed the economic impact of implementing two new technologies at the DeRuyter digester: 1) using biogas to generate transportation fuel rather than electricity, and 2) implementing full-scale nutrient recovery. Here is a summary of my findings for the report and here is the full report.

I specifically studied the Renewable Identification Numbers associated with biogas as a transportation fuel and the potential to earn carbon credits for reduced N2O emissions from nutrient recovery. I presented the results of our study in a brownbag presentation, whose powerpoint I’ve embeded below:
