Wood And Wood Waste

Wood And The Waste From It

nThe most common form of biomass is wood. For thousands of years people have burned wood for heating and cooking. Wood was the main source of energy in the U.S. and the rest of the world until the mid-1800s. In the United States wood and waste (bark, sawdust, wood chips, and wood scrap) provide only about 2 percent of the energy we use today. Biomass continues to be a major source of energy in much of the developing world. 
nOnly about 20 percent of the wood burned in the United States is used for heating and cooking, the rest is used by industries. Many manufacturing plants in the wood and paper products industry use wood waste to produce their own steam and electricity. This saves these companies money because they don't have to dispose of their waste products and they don't have to buy as much electricity.
