Investigating Grey Water Footprint for the Production of Gasoline and Diesel from Biomass via Fast Pyrolysis

This report, created by Argonne for U.S. Department of Energy’s Bioenergy Technology Office (BETO), investigates the grey water footprint of biofuels produced from fast pyrolysis. The system boundary consists of raw biomass handling and pre-processing, fast pyrolysis, oil vapor condensation, two-stage hydrotreating, and hydrocracking to produce a mixture of gasoline, diesel, and jet fuel. The study analyzes the feasibility of wastewater treatment options and identifies limitations on ultimate discharge to the surface stream under water quality standards and pollutant discharge regulations.
