Polyhydroxyalkanoate bio-pellet as well as preparation method and application thereof

The invention relates to the technical field of new materials, and provides a polyhydroxyalkanoate bio-pellet as well as a preparation method and application thereof. The polyhydroxyalkanoate bio-pellet material is prepared by taking polyhydroxyalkanoate, biomass residues, hydrophobic modified water-milled glutinous rice flour and organic intercalation modified montmorillonite powder as main raw materials, premixing, melting, extruding and granulating. According to the preparation method disclosed by the invention, the biomass residues, the hydrophobic modified water-milled glutinous rice flour and the organic intercalation modified montmorillonite powder are synergistically matched, so that less or even no non-environment-friendly reagent is used in an unexpected manner, and the degradable polyhydroxyalkanoate which can play the advantage that a polyhydroxyalkanoate material can be degraded in a natural environment is prepared; and the granular material is better in performance, more in function and wider in
