Costs define
Costs define … smallwood

  • What trees are cut (the perceived value of the treatment)

  • What biomass has value in the market

  • What product sorting, processing, merchandizing occurs


Example
Example smallwood


Assume greengas 1 75 gal

Renewable Oil Int’l Bio-oil smallwood

Assume: GreenGas $1.75/gal

System productivity
System Productivity smallwood

  • Removed ~9 CCF/acre, 3.8 PMH/acre

  • Elemental times ~16 min/CCF

  • Gross time ~25 min/CCF

  • Misc. elements nearly half of all operating time

  • Production rates similar to the Scandinavian studies
