Biomass Organic matter, especially plant matter, which can be converted to fuel as a potential energy source. We will specifically refer to forest resources as biomass.
Biomass harvesting The collection of forest residues through manual or mechanical means for transport to a processing facility. This harvesting normally occurs in conjunction with timber harvesting. It can also be done as a forest thinning operation to reduce fire hazards.
Cellulosic ethanol Ethanol produced from biomass of various kinds, including waste from urban, agricultural, and forestry sources; also called cellulose ethanol.
Chipper Mechanical equipment that reduces small diameter whole trees and residues into smaller diameter pieces. Chippers are normally used in the woods.
Customer Final user of a product or service. In the case of ethanol from woody biomass, the customer purchases the ethanol fuel from a station or distributor for use in their vehicle. These vehicles are known as flexible fuel vehicles.
Ethanol An alcohol that can be produced by fermentation of plant material. The same alcohol is found in beer, wine, and spirits. Denatured ethanol is used for transportation—it is drinkable alcohol that has additives to make it undrinkable.
Feedstock The plants or waste products (such as corn grain, corn stover, switchgrass, sugar cane, or wood chips) used to create biofuels like ethanol or other industrial chemicals. In this context our feedstock is wood chips.
Forest residues Includes tops, limbs, and other woody material not removed in forest harvesting operations in commercial hardwood and softwood stands, as well as woody material resulting from forest management operations such as pre-commercial thinnings and removal of dead and dying trees.
Manufacturer Individual or organization that produces an intermediate or final product for sale to a customer. This customer can be another manufacturer or the final end user.
Petroleum Crude oil, natural gas and their products, such as gasoline, kerosene, wax, asphalt and many other derivatives.
Pre-processing A method for altering the structure (size, shape, or density) of forest materials to improve handling and to reduce transportation costs. Some typical pre-processing methods include chipping and grinding.
Renewable fuel Sources of energy that are produced from resources that can regenerate like corn, sugarcane, forest biomass, and soybeans. These resources and many others are then converted into fuels like ethanol and biodiesel.
Supply chain A coordinated system of organizations, people, activities, information and resources involved in moving a product or service in physical or virtual manner from supplier to customer
Transportation fuel A product like gasoline, diesel, or ethanol which is consumed to produce energy to power a vehicle.
Wood chips Produced by chipping whole trees, usually in the forest. Whole wood chips contain both bark and wood. They are frequently produced from the low-quality trees or from tops, limbs, and other logging residues.
