Abstract： Inresponse tothecurrentsituationoflowutilizationrateoforganic solidresidue valueand limited application of composted products intheclasifiedcollectionofFood Waste（FW）inthefieldofenvironmentalsanitation，afourpoint application modelbased onnature has beenconstructed，namely the“Waste-Fertilizer-Grass-Electricity”cycle model， which includes organic solidresidue，composted products，energy grass，and green electricity.Energy grass planting was carriedoutonacertainabandoned land，with ayieldof 34.32 tper 667 m2.Harvesting energy grass as supplementary fuel forthe waste incineration powerplant can bring 5276.O5 yuan in green electricityconversion income per667m²of energy grass.Through theconstructionof theabove model，the high-valueutilizationofFWhas beenpromoted，carbondioxide emisions havebeenreduced，and thelandfertilityofurban marginal land hasbeen improved.This model can also treat poluted soil through plant remediation，construct green spaces with both ecological functions and landscape value，and generate composite benefits such as dust suppression and biodiversity enhancement.
