Perspectives on woody biomass fuel value and specifications in Alabama
Pulp and paper mills in Alabama buy woody biomass but the specifications required by the mills vary and are not widely known. Some characteristics of woody biomass that are often included in mill specifications include size, species, ash and moisture content. These characteristics are briefly reviewed in reference to how they impact the energy value, physical handling or processing of the material. An informal structured telephone interview was used to obtain the mill specifications and testing procedures used in some of the pulp and paper mills in Alabama. Finally, the relationships between woody biomass characteristics and the mill specifications were summarized.
