Document Type and Number:
WIPO Patent Application WO/2023/171388
Kind Code:
A1
Abstract:
Provided is a resource recycling method capable of efficiently utilizing large amounts of crop residue generated in a field as a resource. The resource recycling method includes a crop residue collection step for collecting crop residues produced in a field, an anaerobic treatment step for methane fermentation of the crop residues collected in the crop residue collection step, and a return step for returning to the field the fermentation residue produced by the anaerobic treatment step. The crop residue collected in the field is subjected to methane fermentation, and the methane gas generated is recovered and effectively utilized as energy while the fermentation residue is returned to the field as compost and fertilizer.
