An object of the present invention is to suppress slagging which is likely to occur in a gasification furnace or a combustion furnace using biomass as fuel. It is another object of the present invention to provide a method and a system that can effectively utilize biomass with less waste. SOLUTION: The ash content contained in the biomass is reduced by squeezing treatment or the like, the ash-reduced biomass is supplied to a biomass conversion facility as a fuel or a raw material, and the ash separated from the biomass by the squeezing treatment or the like is a biomass growing component. To reduce. In addition, as a form of a biomass utilization system suitable for carrying out the above-described biomass utilization method, the biomass utilization system includes an ash reduction treatment device for separating ash contained in biomass, and gasification by supplying ash-reduced biomass. And a gas purification device for purifying gas gasified by the gasification furnace. [Selection diagram] Fig. 1 |
