Abstract: A method for manufacturing environmental protection sponge comprises the steps of mixing material which are formed by predetermined ratios so as to form a mixing material; wherein the material contains PVA and starch; agitating and then boiling the mixing material; filling the mixing material into a mold so as to form a sponge; the sponge being taking out from the mold; washing the sponge; dewatering the sponge so as to form as environmental protection sponge; drying the environmental protection sponge; compressing the environmental protection sponge through at least one stage and then the compressed environmental protection sponge being cooled; rolling the environmental protection sponge by turning the environmental protection sponge through at least one roller so that the environmental protection sponge has a uniform structure; cutting and printing patterns on the environmental protection sponge; and packaging the shaped environmental protection sponge.
