The interest in renewable energy is increasing because of higher growth in global energy consumption and limited fossilfuel reserve. In Republic of Korea, the necessity of lignocellulosic biomass is increasing and research on utilization of logging residueis growing. , due to low economic efficiency, domestic logging residue is not being utilized, and many studies are being conducted tosolve this issue. The final harvesting cost of timber and logging residue in the -to-length (CTL) system using the excavatorinvestigated through field survey. roductivity and machine costs were calculated time and motion study methods and German forestryoperation and machine board (Kuratorium für Waldarbeit und Forsttech nik e.V, KWF) analysis methods. The harvesting costs oftimber and logging residue were calculated 43,968 KRW/ton, and 71,079 KRW/ton, respectively. This study helps to validate data onthe economics of timber and logging residue in the existing CTL system using an excavator, and presents the feasibility of the supplyand utilization of hole-tree system using high-performance forestry machines.
