Census Bureau, 2002 County Business Patterns. Depending on the size of a company (number of employees) and assumptions on the wood waste generated by a company derived from Wiltsee’s study6, the results of this analysis are shown in Figure 16 and Table 5. According to this study, pallet and lumber companies generate about 300 tons/year, and a small woodworking company typically generates between 5 and 20 tons/year of wood waste. 6 Wiltsee, G, Urban Wood Waste Resource Assessment, Appel Consultant, Inc.
The geographic pattern of this resource availability by county is shown on Figure 25, and Figure 26 illustrates the numbers normalized by county area. The crop, forest, and primary mill residues provide about 70% of the total biomass resources (Figure 28 and Figure 29). While the resources from other feedstocks are relatively insignificant, they could play an important role at a regional and local level.

S. Total 30,902 Municipal Discards Methane Emissions from Landfills The methane emissions from landfills depend on three key factors: (1) total waste in place; (2) landfill size; and (3) location in an arid or non-arid climate. Data on the landfill locations and the waste in place was obtained from EPA’s Landfill Methane Outreach Program (LMOP), 2003 database. For this study we used the landfill size defined by EPA. 1 million tons of waste in place. With regard to moisture as a factor in the methane production, landfills in non-arid climates are believed to produce more methane per unit of waste in place than do landfills in arid climates.
