Woody Biomass Utilization

Eldorado National Forest

Georgetown Ranger District, California

A field demonstration of a unique piece of equipment was conducted on September 10, 2003, on the Georgetown Ranger District, Eldorado National Forest. The demonstration was sponsored by the Eldorado National Forest and the John Deere Corporation. The John Deere 1490D slash bundler collects, compresses, and bundles thinning slash and logging residues for effective and economical transport to a co-generation plant for energy production. The machine was tested on eight different sites in four western states. Each project site involved pretreatment measurements, elemental production study, post treatment measurement of effects, and technology transfer through "field day" demonstrations.

The original demonstration site was not practical due to the brittleness and small piece size of the slash. Bundles had poor integrity and did not hold together. The location of the demonstration was changed to ensure adequate machine performance.

The wood moisture contents of the slash was about 10 percent.

The alternate demonstration site included bundling slash from a landing pile.

Bundle size, weight, and moisture content was measured.

One truck load of bundles was transported to Wheelabrator's wood-to-energy plant in Anderson, California, for grinding and burning tests.

The slash bundling demonstration was well-attended and generated interesting discussion about fuels reduction and wood utilization.
