Economic evaluation of biopulping

摘要

The fungal pretreatment of wood chips prior to mechanical pulping (biopulping) reduces the electrical energy requirements during refining, potentially increases mill throughput, and improvs paper strength, which have a direct economic benefit. An economic analysis of a 600 t/d termomechanical pulp (TMP) mill indicates that based on energy savings alone, the process is economically feasible, resulting in voerall savings of about
