Utilization of logging has been spreading for woody biomass power generation over a wide area as well as small scaled regional use such as "wood station". The recovery systems can be classified into large scaled and small scaled ones. The large one is typically operated by a single cooperation using large trucks for intensively accumulated logging residues at landings. On the other hand, the small one uses small trucks or light-weight trucks operated by many shippers. They ship logging residues to intermediate landings, so called "wood station", where the residues are transferred to wood chipping factories or processed to wood chips and then transferred to burning facilities. Although large scaled systems would generally have superiority in a view point of cost efficiency, small scaled systems may be better than large scaled ones in other points of view other than cost efficiency. The present paper discusses with comparison of the superiority between such different scaled systems on not only cost efficiency but also CO2 emission, energy efficiency, and contribution to regional economy.
