Creating Biojet Fuel

Packing forest residues for transport

Vertical blowing of forest residuals
Vertical blowing of forest residuals

Transporting a low value product like forest residuals from a timber harvest site to a processing facility represents a significant economic and logistical challenge for a wood to biofuel supply chain. One way to ensure that transport costs are as low as possible is to maximize the amount of wood residuals carried per trailer load.


US Navy uses Gevo’s alcohol-to-jet fuel for supersonic flight


The US Navy is testing a 50/50 alcohol-to-jet (ATJ) fuel produced by Gevo Inc. for use with their F/A-18 “Hornet” jets. They recently announced their first successful supersonic flight using Gevo’s ATJ fuel derived from isobutanol.

You can read Gevo’s press release here.

Gevo is an affiliated member of NARA. For NARA, they are adapting their ATJ technology to use the simple sugars contained in forest residuals as a feedstock for isobutanol …more

NARA Graduate Student Research – The 2014 Western Forestry Graduate Research Symposium

By: Janna Loeppky, M.F. Candidate, Oregon State University

One of the most important steps in the advancement and continuation of research is
the investment in future generations of researchers. While much of the ideas for research
originate with academic faculty, the work is conducted by graduate students.  These students
are contributing to NARA’s goals through groundbreaking studies in their respective fields.
Contributions to original research begin with an area of interest and slowly evolve into a

New report on logging utilization in Idaho

Front cover of report
Front cover of report

Logging utilization studies describe how trees are harvested in commercial operations and account for how the various tree parts are used. This information helps land managers evaluate their logging operations and can reveal utilization trends over time and within various regions.

Logging utilization data is particularly valuable to NARA researchers because it provides a basis used to …more

Transportation of residues: would you bundle?

By: Janna Loeppky, M.S. Candidate, Oregon State University

In the forest industry, timber harvesting supplies the demand for one of the world’s most renewable resources: logs. Although the majority of consumers may only know about the final products purchased from mills and lumberyards, the harvesting operation is quite extensive. From stump to mill, the costs for extracting desirable trees to fulfill market demand range in cost depending on the size of the unit being harvested and the amount of …more

Estimating nutrient removals under varying intensities of harvesting residue utilization

By: Janna Loeppky, M.F. Candidate, Oregon State University

Nitrogen is the most abundant atmospheric element and a major nutrient required for plant and tree growth. The vast majority of nitrogen in forest soils and tree biomass is fixed from the atmosphere by soil micro‐organisms. Although the vast majority of nitrogen in most forest ecosystems is held in soil organic matter, some sites contain larger portions in live biomass and may therefore be susceptible to reductions in long‐term site productivity …more
