Wood residues produced by the roundwood processing industry have been utilized heavily for both energy and non-energy purposes. The last comprehensive study of Pennsylvania's roundwood processors was conducted in 1988 by Wharton and Bearer (1994), who found that firms utilized and/or disposed of 120 million cubic feet (mmft3) of residues produced from a total roundwood volume of 1.450 billion board feet (BBF). Data collected from a mail survey of all identified roundwood purchasers in Pennsylvania in 2003 (n = 334) indicated that roundwood purchase volume decreased slightly to 1.266 BBF with 94 mmft3 of accumulated residues that were utilized and/or disposed of as waste. Roundwood purchasers include any Pennsylvania firm that bought roundwood (sawlogs, veneer logs, and pulpwood) from Pennsylvania and adjoining states in 2003. This total volume of residues consisted of 20 percent bark, 45 percent coarse, and 35 percent fine residues in 2003. The specific end uses for these three residue types changed dramatically over the 15-year span (1988 to 2003) with overall residential fuel use declining and uses for pulp and fiber composites, industrial fuels, and agricultural/horticultural products increasing. Pennsylvania's roundwood purchasers utilized 99 percent of their accumulated mill residues in 2003, a 6 percent increase from the overall percent utilized in 1988.
