Read More1 Introduction Pulpmills are among the largest users of woody biomass and typically store and process huge volumes of wood chips prior to the pulping process. Storage volumes of 120,000 BDt (750,000 m³) are not uncommon. The value of these chips is in the tens of millions of dollars, so mills have very specific requirements […]
