Abstract

This paper aims to design the woody biomass supply chain for co-firing in the coal power plant. The woody biomass supply chain consists of 4 processes; Collection, Resource transportation, Preprocessing, and Fuel transportation. Preprocessing is divided into two processes such as Drying and Fuel production. Sawmill residue, construction waste, forest residue, thinning residue, and pruning of fruit tree are treated as raw material. Wood chip, pellet, and torrefied pellet called black pellet are treated as bio-fuel. The transportation of raw material and bio-fuel is optimized by using Geographical information system (GIS). As a case study, the woody biomass supply chain in Tohoku region is designed. The potential of raw materials is 37 PJ/year, and the availability is 3.6 PJ/year. As all resource is utilized in power plant, the lowest amount of energy consumption is 0.9 PJ/year that the all raw material is consumed to produce the pellet in resource generation points. And the lowest cost is 40,000 JPY/t of black pellets that are produced in resource generation points. It is obtained that the drying process and raw material transportation are dominant on energy consumption and cost.
