Abstract: A method of preparing biodegradable water-resistant paper utensils which includes the steps of: (a) preparing a pulp aqueous slurry at a consistency of about 4%; (b) adding surfactant to the slurry; (c) thereafter, adding between 8 and 30 percent weight of a biodegradable and water-resistant agent to the slurry to form a slurry mixture; (d) refining the slurry mixture at a consistency of about 4 percent to a desired drainage; (e) diluting the refined slurry mixture and adding an aggregating agent thereto to form a furnish; and (f) after step (e), forming the furnish to obtain biodegradable, water-resistant paper board or directly a paper utensil. The forming step can be through a hot-press at a temperature of 115.degree. to 170.degree. C.
