Stemwood and whole trees of lodgepole pine (Pinus contorta Dougl. var. latifolia L.) were evaluated asraw materials for fuel pellets in a pilot scale pelletizing study. Pellet and pelletizing properties were measured andmodeled in an experimental design where raw material moisture content (%), die channel length (mm), and storage time(days) were varied. Additionally, ash contents (%), extractive contents (%), and ash melting temperatures (°C) wereanalyzed. For both assortments, raw material moisture content was positively correlated to pellet bulk density anddurability (range 9-13%, wet base). Both assortments had ash contents below 0.7%, and thus, fulfilled the demands forclass A1 pellets.
