The increasing demand for paper has raised the need for low-cost raw materials and also for the development of new process in order to boost production. Non-wood fibers, for example agricultural residues and annual plants, are considered an effective alternative source of cellulose for producing pulp and paper sheets with acceptable properties. This paper reviews some physical and chemical properties of non-wood pulps which have effects on the making of paper. The less polluting pulping processes that use organic solvents are of interest for pulp production. The delignification of the Organosolv pulping process depends on the type of Organosolv methods and cellulosic sources used. The chemicals and cooking conditions, such as the catalysts, solvent concentration, cooking temperature, cooking time, and liquor to raw material ratio, all influence the properties of the pulp and paper
