BioSAT is a model for estimating costs for procuring cellulosic biomass to biomass-using facilities. Currently, we have gathered data to reflect the cellulosic biomass supply in the 13 Southern United States, and our data development is on-going to expand our reach for 20 Northern states.
Forest resource data were obtained from two sources: the Forest Inventory and Analysis Database (FIADB
) version 3.0 (U.S. Department of Agriculture, Forest Service, 2008) and the Billion Ton 2 (BT2) study (Perlack et al., 2005
). The FIADB database includes county level estimates of all-live total biomass, as well as average annual growth, removals, and mortality. Estimates of mill residues and logging residuals are obtained from the BT2 study. County-level agricultural resource data were derived from the National Agricultural Statistics Service
County level estimates are re-allocated to "zip code tabulation areas" (ZCTA's). Zip codes are aligned to ZCTAs and are based on the 2000 census definition from the U.S. Census Bureau. Confidence levels of individual county level FIADB data can be wide. Therefore, BioSAT does not use individual ZCTAs in the system, but ZCTAs are combined together into larger biosheds.
Transportation costs, resources costs, and harvesting costs (if appropriate) are estimated for biomass quantities in a bioshed. Resource cost data for the southeastern U.S. are from Timber Mart South (TMS)
. Resource cost data in the northern U.S. are from Timber Mart North
and state-level reporting agencies
With this information, BioSAT can help you achieve greater visibility into the supply of cellulosic biomass in the current marketplace.
