Technical Bulletin No. 0906: Alternative Fuels Used in the Forest Products Industry: Their Composition and Impact on Emissions
Available data on the composition of tire-derived fuel, petroleum coke, tall oil, turpentine, various types of wood products, rejects from pulping of old corrugated containers (OCC rejects), non-recyclable paper kraft digester knot rejects, and pulp mill wastewater treatment plant residuals are summarized. These alternative fuels are generally used to supplement fossil fuels and/or wood residues in boilers, although petroleum coke and tall oil serve as the primary or supplemental fuel in kraft mill lime kilns. Emission test data gathered during trial burns or routine use of alternative fuels have been compiled and analyzed.
