Biomass Resource Assessment Part I - Gainesville Regional Utilities

The greatest competition for logging residues is likely to be from whole tree harvesting ofsoftwood pulpwood, and the use of tree tops for boiler fuel at pulpmills. Two of the pulpwoodmill facilities identified in Table 3, Buckeye Florida LLC Cellulose and Rayonier FernandinaBeach, are believed to use some portion of logging residues in addition to mill wastes to generateelectricity. Thus, we reduced our assumptions of availability of current logging residues from90% to 60%. These values exclude stumps, leaves, and bark.Figure 6. Geographic location of biomass using facilities identified in Table 3.2.2.6. Supply curve constructionWe constructed supply curves using the above information regarding quantities,distribution, and total costs for each woody biomass resource. Assuming homogeneousdistribution of woody biomass resources within each county (a necessary assumption giventhe FIA and US Census source data), we calculate the amount of woody biomass in each26
