Abstract: 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 3 ), for example in a range of 650 to 850 kilograms per cubic metre (kg/m 3 ).
