07 Assessment

Advantages

  • Carbon-negative material (sequesters CO₂ during growth)
  • Biodegradable at end of life
  • Low thermal conductivity (0.04-0.06 W/m·K)
  • Inherent fire resistance through char formation
  • VOC-free and non-toxic
  • Grown from agricultural waste
  • Lightweight (100-200 kg/m³)
  • Good acoustic absorption (75% at 1000Hz)
  • Can be moulded into complex shapes

Constraints

  • High water absorption without treatment
  • Limited mechanical strength for structural applications
  • No established Australian Standards
  • Production time of 10-20 days
  • Requires controlled growth conditions
  • Limited commercial availability in Australia
  • Variability in properties based on substrate and species
  • Requires protective coatings for exterior use
  • Currently higher cost than conventional insulation

08 Applications
