Abstract:

The use of forest biomass as an alternative source for bioenergy production has become a significant issue in Tennessee. This study used the Sub-Regional Timber Supply model to analyze the regional aggregate forest biomass feedstock potential and the impacts of additional pulpwood demand on the regional roundwood market through 2030. Two scenarios examined the impacts of building a biorefinery facility of 20 and 50 million gallons annual capacity in the state in 2015. The third scenario investigated the impacts of an Energy Information administration (EIA) reference case. The projection results suggest that there is sufficient hardwood pulpwood supply for a 50 million gallon biorefinery facility in Tennessee. It is possible to meet the increased demand of the EIA reference case without affecting the hardwood pulpwood market in the short run, but not in the distant future. The additional demand for softwood pulpwood will affect the softwood market substantially, but the impacts on the hardwood market are comparatively small. Hence, it is more feasible to increase the use of hardwood pulpwood for renewable energy rather than softwood pulpwood. These results will be very helpful in sustainably supplying forest biomass for bioenergy production in Tennessee.
