Welcome to COBS

The Comparison of Biofuel Systems (COBS) project at Iowa State University investigates a range of biomass feedstock production systems with respect to:

  • Potential for biomass production, fossil-fuel replacement, and net energy returns,
  • Potential to reduce greenhouse gas emissions and to increase belowground carbon storage,
  • Potential to maintain soil quality and reduce water-quality impacts of nutrient exports, and
  • Net economic return to biomass producers and the environment.
