The invention relates to uncoated, fiber/starch composite materials manufactured without the use of fluorochemicals or additional binders that offer superior oil and grease resistance properties. Addition of an internal sizing agent in the preparation of the fiber/starch composite materials results in superior hot water and cold water resistance properties. The fiber/starch composite materials may be used for the manufacture of food service containers. The invention also relates to methods of preparation of the fiber/starch composite materials.

There is disclosed a process of manufacturing a fibreboard from a waste material, for example from a corrugated waste material, wherein the process comprises: refining in a range of 5 to 30 percent of the waste material into micro-fibrillated cellulose (MFC), using a mechanical micro-fibrillation process; pulping in a range of 70 to 95 percent of the waste material with water to obtain a waste pulp; dispersing the micro-fibrillated cellulose (MFC) into the waste pulp to obtain a micro-fibrillated waste pulp; moulding the micro-fibrillated waste pulp by applying a pressure to obtain a moulded fibreboard, using a moulding process; and drying the moulded fibreboard at a temperature to obtain the fibreboard with a density in a range of 500 to 1000 kilograms per cubic metre (kg/m.sup.3), for example in a range of 650 to 850 kilograms per cubic metre (kg/m.sup.3).
