Yield and properties of pulp from eucalypt wood grown in Florida

Abstract

Pulpwood is the primary product goal of limited commercial planting of eucalypts in Florida. Pulp yield and properties of four species for three product goals were investigated. NSSC pulping of three eucalypt species and a representative native hardwood mix showed substantially higher yields of pulp from the eucalypts with acceptable strength for corrugating medium. Yield of dissolving pulp from Eucalyptus tereticornis wood was slightly lower than from sweetgum. Eucalyptus grandis, E. robusta , and E. camaldulensis wood gave screened yields of kraft bleached grade equal to those of representative native hardwood controls at comparable kappa numbers. Strength of handsheets was inferior while brightness was superior to controls. Eucalyptus tereticornis gave substantially lower screened yields of kraft bleached grade pulp at equal or higher kappa numbers than the representative hardwood controls.
