Process for the production of a fertilizer from bark
Patent
·
OSTI ID:6327114
The production of a fertilizer from tree bark is improved by a process of the type wherein crushed waste bark is treated together with waste molasses under elevated pressure and at a temperature of 75 to 140/sup 0/C. For a time of 10 min to 2 h. Said time is dependent on the treatment temperature, and the improvement comprises adding yeast to the waste molasses, and maintaining its temperature at 30 to 40/sup 0/C for 35 to 45 hours, whereby its ph value decreases to 3-4, before it is mixed with the ground waste bark.
