Abstract

This study was conducted to compare the productivity and cost of harvesting and processing system between manual and mechanized methods in short-rotation coppice (SRC). The wood chips were divided into class based on their characteristics. There was also a consideration whether the fuel conditions of the energy facilities were suitable. The cost of mechanized harvesting system (48,525 won/Gwt) was lower than that of manual harvesting system (107,350 won/Gwt) by approximately 54.8%. The results of the fuel properties analysis for wood chips A (chipping immediately after harvesting) and wood chips B (chipping after drying) showed that wood chips A was not suitable because of the bulk density, and wood chips B was evaluated to be a second class based on the quality standards of wood chips in all conditions. The wood chips B was available at all energy facilities except gasification combined heat and power system (CHP), which required low moisture content (less than 13%). In addition, if the quality of wood chips was improved, (increased storability, uniformity of wood chips size, and reduced fines) by performing drying and screening operation after chipping, it can be used for all energy facilities.
