overview
Dissolved pulp (DP) is the primary feedstock for producing man-made cellulosic fibres (MMCF) like viscose staple fibres (VSF), modal, viscose filament yarn (VFY), lyocell and acetate with high cellulose content (alpha-cellulose). Dissolved pulp production includes processes to extract cellulose from wood or textile waste as raw material, followed by bleaching to improve the brightness of the pulp, which is then chemically processed to create regenerated cellulosic fibres for various textile applications.
ZDHC has developed the Dissolved Pulp Guidelines V1.0 to enhance the transparency of responsible production in the entire MMCF supply chain, from wood sourcing to man-made cellulosic fibre (MMCF) production.
The ZDHC Dissolved Pulp Guidelines V1.0 is an initiative by ZDHC to address the use and discharge of chemicals in wood-based dissolved pulp manufacturing. The guidelines include chemical recovery, wastewater and air emission requirements for wood-based dissolved pulp facilities.
