The invention provides a high-intensity starch-based degradation environmental protection material and a manufacturing method thereof, which relates to a rapid degradation raw material used for manufacturing disposable tableware and disposable wrappage and the manufacturing method thereof. The present disposable foaming plastic tableware has the disadvantages of hard heat insulation, complicated process line, high production cost, undesirable production quality and white pollution. The components of the product include macromolecular natural starch, polyvinyl alcohol, plant sugar, polyvinyl alcohol, a degradation control agent, a multipolymer of polycaprolactone and poly-beta-hydroxybutyrate and hexa-butyl ester hexa-butyl glycan; wherein, the starch is 51-80 weight portions, the polyvinyl alcohol is 12-20 weight portions, the plant sugar is 2-10.5 weight portions, plasticizer is 2.5-8 weight portions, the degradation control agent is 0.2-1 weight portions, the multipolymer of polycaprolactone and poly-beta-hydroxybutyrate is 5-9 weight portions and the hexa-butyl ester hexa-butyl glycan is 0.2-0.5 weight portions. The high-intensity starch-based degradation environmental protection material of the invention is used for manufacturing the disposable tableware and the disposable warppage.
