Long-term soil productivity and sustainability of forest harvest residue harvesting
Forest harvesting intrinsically removes organic matter and associated nutrients; these exports may impact soil productivity of managed forests. We will examine the effects of removing forest floor and harvest residues on ...
Pacific Northwest Wood-Based Biofuels: Site Selection & Design
This document presents Pacific Northwest supply chain estimates, case studies of specific sites within the PNW region, and conceptual master plans for consideration by stakeholders and communities as they search for ways ...
'Woods-to-Wake' life cycle assessment of residual woody biomass based jet-fuel
The residual woody biomass (a.k.a harvest slash) produced during forest harvest operations in the Pacific Northwest, is generally burned in the forest or left on the forest floor to decompose. Drop-in biofuel production ...
Production of Lignocellulosic Isobutanol by Fermentation and Conversion to Biojet
This report describes the fermentation and process technology developed by Gevo and used to convert forest residuals into biojet fuel.
Feedstock Sourcing: NARA Years 4-5
The report characterizes the varied forest residual feedstock samples assessed during the NARA project and explores economic sensitivity to key characteristics (size, moisture, chemical composition).
Olympic Peninsula: Site Analysis Report
This report provides supply chain estimates and case studies for the Herman Brothers operation in Port Angeles, WA, and the Port Townsend Paper Corporation in Port Townsend, WA.
Informing and Engaging Stakeholders
This report describes Northwest Advanced Renewable Alliance (NARA)’s outreach activities used to enhance bioenergy literacy and build supply chain coalitions and regional alliances.
SPORL Pretreatment of Douglas-fir Forest Residue for Precommercial Scale Productions of Sugar/ Biofuel
This report describes the development of pretreatment conditions used to develop 1,000 gallons of biojet fuel derived from forest residuals.
Mild Bisulfite Pretreatment of Forest Residuals
(Northwest Advanced Renewables Alliance, 2015)
In this report, researchers evaluated the effect of wood chip size, chemical loads, reaction time and temperature on simple sugar yield from the Mild Bisulfite pretreatment procedure.
Plant Cell Walls to Alcohols
This lesson looks at the break down of plant material to demonstrate the production of biofuels.
