OTL’s torrefaction facility is associated with an existing sawmill to eliminate duplication or new development of procurement networks, timber harvesting/hauling, and wood processing.  This arrangement provides each mill another outlet for residuals as well as allow them to better compete for timber sales that have large amounts of non-marketable (non-saw log) material.  For the first facility, an adequate volume of biomass is available from the existing 10-year USFS stewardship contract on the Malheur National Forest, with additional volume available from existing Forest Service “Shelf Stock”, mill residuals, private land treatments, timber sales, juniper removal and other forest restoration treatments.

[3] Inasmuch as the HTC or steam exploded biomass originated from material passing 50 to 300 mesh, it is reasonable that subsequent grinding will reduce the pellet to this same size range 

Torrefied Biomass will be available earlier than HTC processed fuel; for additional detail, please contact us.

Fuel Quality and Specification

Torrefaction is a process that converts biomass to a high-grade, renewable, solid biofuel. The process involves a thermo-chemical treatment of biomass between 200 and 300 degrees Celsius (400 – 572 degrees Fahrenheit) in a controlled environment. During this treatment, moisture and volatile organics are removed and much of the hemi-cellulose is decomposed.

The solid biofuel that is produced has significant advantages compared to other biomass fuels and can be readily co-fired or fired 100% in existing pulverized coal power plants. The torrefaction process changes the biomass so that it is easily ground, has a higher energy density than raw biomass, and is hydrophobic or resistant to moisture. These characteristics allow torrefied biomass to perform similar or superior to coal in existing pulverized coal power plants.

The torrefaction process involves many physical and mechanical steps that are widely used in the forest products sector. Experience with the collection, processing, transporting, handling, drying, and manufacturing of products from woody biomass positions local firms, like Ochoco Lumber (operating Malheur Lumber Company), to be a key partner in operating a torrefaction facility.

Oregon Torrefaction can offer torrefied biomass fuel with qualities comparable to western Powder River Basin Sub-bituminous coal:
