Due to the global recession the cost of raw materials used in handmade paper industry in India are increasing one side and on the other side the export market is badly affected. Also, the capital costs are going higher day by day thus forcing the Indian handmade paper industry on back foot. Keeping in mind the present research work with the aims to help the handmade paper industry in different parts of the country so that they come out with the problem of good quality natural lingocellulosic raw materials. The ligno-cellulosic raw materials Banana (Musa sapientum), Ankara (Calotropis procera), and Pineapple (Ananas comosus) which are locally available may be used by the Industry in India. The research paper covers the potentiality about the fibres and its morphological & chemical nature as well as the alkaline sulphite pulping technology. The chemical characteristics of these fibres i.e. lower lignin content, higher alpha cellulose coupled with average higher fibre length could prove its applicability for the manufacture of a good quality handmade papers and converted paper products. As a reinforcing fibre by blending these fibres with the traditionally used hosiery waste could find suitable place as an alternate raw materials with a better strength properties. The present paper special attentions were given to banana fibre which deals with chemical pulping technologies like alkaline sulphite pulping for the production of pulp. The resultant spent liquor obtained from banana cooked sulphite pulping process has been found to be useful as a plasticizer in concrete admixture.
