ABSTRACT
The term biomass has been an important part of legislation enacted by Congress for many decades and has evolved over time, resulting in a variety of differing and sometimes conœicting denitions [1]. These denitions are critical to all parties engaged in the research, development, nance, and application of biomass to produce energy. The term biomass is more generally dened as “different materials of biological origin that can be used as a primary source of energy” [2-5]. Alternately, biomass is dened as “plant materials and animal wastes used especially as a source of fuel” [6]. These biomass denitions contain the generalized statements for the origins of the materials or their intended uses and applications, however, the denitions are not meant to provide sufcient and necessary conditions for certain specic material to be classied, or qualied, as biomass.
