Abstract
Bedding material for livestock or Hydromulch for soil treatment is produced by extruding straw mixed with bio-char through a conventional cubing system. The cubing process generates friction in turn changing the properties of the straw making the straw particles highly absorbent while binding the bio-char and any dust into the mixture. The mixture can be used for bedding where the bio-char acts as an absorbent. The mixture can also be used in soil remediation by spreading over the soil in dry or Hydromulch where the bio-char acts to filter contaminants and can act as a binder for an fertilizer admixed into the mixture for seeding.
