Model description 

1. Purpose of the model: The objective of this work is to analyze the dynamics of biomass resource distribution across multiple industries under different conditions. To this end, we developed a simulation model that projects the volume and price dynamics between the biomass resource base (supply) and different demand industries including intermediate processing (i.e., mobilization) and end-use markets (traditional, companion, and biofuels). This allows modeling of resource mobilization and price developments over time given varying levels of companion and biofuel market growth. The model is limited to the U.S. southeast, the nation’s primary supply shed for purpose grown softwood. It covers Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Eastern Texas, Virginia and West Virginia. The region boasts the vast majority of installed wood pelleting capacity and the highest annual production of wood pellet. 

2. Methodology: Detailed description of the model can be found in our published article .

This model was built using the system dynamics modeling method.
