BIOMASSBIOMASS
Any organic matter that is available on a Any organic matter that is available on a renewable or recurring basis , including renewable or recurring basis , including agricultural crops and trees, wood and wood agricultural crops and trees, wood and wood wastes and residues, plants ( including aquatic wastes and residues, plants ( including aquatic plants), grasses, residues, fibers, and animal plants), grasses, residues, fibers, and animal wastes, municipal wastes, and other waste wastes, municipal wastes, and other waste materials. Biomass is generally produced in a materials. Biomass is generally produced in a sustainable manner from water and carbon sustainable manner from water and carbon dioxide by photosynthesis. There are three dioxide by photosynthesis. There are three main categories of biomass – primary, main categories of biomass – primary, secondary and tertiary. secondary and tertiary.

Intensive management of Plantation forests is widely practiced in the Southern States of the USA resulting in a significant amount of thinnings destined for pulp mills as pulpwood
US pulpwood consumption has decreased in the South since the 1990’s
Decrease can be attributed to higher costs: Changing paper demand High labor costs High fiber costs High tax rates
