Contents of Biofuels Life Cycle

Lecture Notes

As we conduct life-cycle assessments on the preproduction, the production, the distributions, and utilization of biofuels; we're most interested in the production of greenhouse gases. In this slide, we see a biofuel for which we're interested in the production of greenhouse gases from the time the feedstock begins growth, through harvesting and then to transporting it to the bio-refinery. At the bio-refinery it's converted into ethanol or to biodiesel. From there it's distributed to where the end-user can use it. At each one of these stages, we are interested in the greenhouse gases that are produced.
