1. The process of making a degradable starch-based resin comprising:

  • peeling a starch-based plant feed stock selected from one or more Sago plants;

    extracting a quantity of starch content from the peeled starch-based feed stock;

    drying at least a portion of the quantity of starch content by substantially removing the water content from the starch content resulting in a base material in the form of a dried starch polymer;

    processing the base material in a reactor into a quantity of soft starch polymer;

    subsequent to the processing step, further polymerizing the soft starch polymer by combining and reacting in a reactive-extruder with maleic anhydride, a polyethylene-based plastic resin, a quantity of glycerol, and an oil to define a further polymerized starch, and;

    partially cross-linking the further polymerized starch with the polyethylene-based plastic resin to form the degradable starch-based resin.
