Abstract

Oregon Torrefaction, LLC (OTL) and the US Endowment for Forestry and Communities has formed Restoration Fuels, LLC (RF) to construct and operate a 12 ton/h kiln torrefier which targets approximately 100,000 tons of torrefied woody biomass production annually. The plant will be colocated at the Malheur Lumber Mill, located in John Day, Oregon. Biomass sourcing will be principally small diameter, low-value wood from surrounding or nearby national forests including the Malheur and the Ochoco National Forests. The bulk of the woody biomass will be Ponderosa Pine from the dry land forests that surround John Day. Biomass coming from national forest areas have been evaluated for compliance with the US National Environmental Policy Act (NEPA) and are termed “shelf ready” for treatment. Restoration Fuels is now in the process of acquiring biomass supply to feed the torrefier. Early discussions with potential domestic and off-shore customers points to the need to have torrefied, densified test samples available for their evaluation, and it is in OTL’s interest on behalf of RF to produce a test batch of torrefied biomass that would be representative of RF’s future fuel product and to make samples available to serve customer interests. The effort is funded by the US Endowment and US Forest Service. To accomplish the test sample production, the OTL provided 32.8 tons of wood chips to the Biomass Conversion Lab (BCL) located in Coleraine, MN for a sustained torrefaction production run using ponderosa pine as feedstock. The targeted specification for the torrefied wood chips as requested by OTL was 9,500 btu/lb. The BCL successfully torrefied and provided over 14 tons of torrefied feed stock to the OTL that met this targeted specification.
