素材にとっての重要性
Pulp and paper is a different business from lumber at every point. It wants small, uniform, fast-grown fibre rather than large clean logs, it is capital-intensive and runs continuously, and its cheapest input is often recovered fibre rather than wood at all - which links waste-paper policy directly to roundwood demand.
