About Bamboo Pulp

  • Bamboo pulp is increasingly being used in the manufacture of Tissue
  • Seen as a more environmentally friendly and sustainable alternative to wood-based pulps
  • If farmed responsibly benefits include
    • Faster growing and higher yields
    • Can help to reduce deforestation
    • Captures more carbon dioxide and releases 30% more oxygen
    • Lower maintenance
    • Improved sustainability
  • Can be good pulps for Tissue but high levels of contaminants can cause operational and quality problems
  • Typically used as a replacement for long fiber
  • Mills can be integrated or purchase market bamboo pulp

Potential Problems With Bamboo Pulps

  • Bamboo pulps typically contain higher levels of contaminants than pulp obtained from wood
    • Fines and extractives
    • Higher inorganics particularly silica
  • These will make the Yankee coating layer
    • Harder
    • Dustier
    • More abrasive resulting in increased doctor blade wear
  • Ultimately these will
    • Reduce softness and hand feel
    • Lower machine runnability
    • Reduced doctor blade life
  • Problems will be greater in integrated mills
    • Pulp drying will remove some contaminants

Bamboo pulp VS other commonly used pulps

  • This data clearly highlights the source of the problems created by bamboo pulps
    • Fines levels are significantly higher
    • Higher levels of extractive materials
    • Increased ash levels particularly silica
  • These can be controlled by the right chemical approaches
