Abstract: The increasing of world population, quality of life and industrialization will lead to increase of consumption of paper and paperboard globally, this will cause the increase demand for fiber. New legislative regulations enacted in response to the demand of environmentalists, environmental groups and governmental organizations in various countries are restricting the logging of treess which is expected to affect the supply and price of wood to the international pulp and paper industry. So, the insufficient supply of fiber for papermaking has necessitated the paper industry to search for alternative fiber. Generally, lignocellulose material from wood or non-wood plant consists of cellulose, hemicellulose, lignin, extractive and a minor part of inorganic matter. Information on the chemical composition is important in deciding techno-commercial suitability, pulping method and paper strength. Kenaf has been identified as one of the potential sources for pulp and paper production. Generally, the selection of pulping process depends on the function of the end product. Kraft, soda and soda-AQ processes have been the most frequency used for kenaf. In comparison to kraft pulping, soda-AQ process has higher yield at the same kappa number and better delignification without environmental damage due to no sulphur emissions. Soda-AQ pulping with kenaf whole stem needs less chemical consumption with higher pulp yield than soda. Also, it is considered to be suitable for small scale mills.
