FIELD: biotechnology.
SUBSTANCE: present invention relates to a method for delignification (100), which is used to remove lignin from a mixture of biomaterials, stacked in the form of a heap, and in fact includes the steps: putting (101) biomaterials in a heap, processing (102) heaps with irrigating solution containing water or an aqueous solution that contains chemical materials, moving (103) the irrigation solution, which reaches the base of the heap and contains leached substances, through the drainage system to the reservoir pond or storage, re-supplying (104) the irrigation solution transferred to the storage pond or storage, for irrigation, after performing verification and optimization of properties, obtaining (105) a leached heap after termination of irrigation, when the delignification process is completed.
EFFECT: method is used to remove lignin from a mixture of biomaterials.
