Pineapple (Ananas comosus) is an significant fruit of India. The information provided by Indian Horticulture Database suggest that Pineapple is cultivated in an area of 85.4 thousand ha and total production is 1,353.1 thousand tons in India, up to year 2006 and also that it is the 6th largest country in the production. In this paper, modern scenario for commercial products, obtained by extract of  its fibre is being discussed. It is abundantly grown in almost entire North East region. Assam, Manipur, Tripura and Meghalaya are the main contributing states in the production of Pineapple. Assam has 14.6 ha area and 241 thousand tons production up to year 2006. The North East region has remarkable advantages of fertile and organically rich soils, ample rainfall, water resources and great climatic diversity supporting diverse cropping possibilities. Pineapple leaf contains only 2.5-3.5% fibre, covered by a hydrophobic waxy layer. Extraction of thousands of tons of pineapple leaf fibre can be done after the harvesting of the fruit. The fibre extraction alone from the leaves is not economically viable, so the utilization of the residual sludge, remained after the process can be done in vermicomposting and other applications. The commercial products manufactured by using the PALF are of great importance in textile industry. The South Indian Textile Research Association (SITRA) has also commissioned a PALF extraction plant in Tripura. This review paper aims to indicate the developing trends in extraction methods and economic optimization of the products in the market obtained by the PALF in Assam, India. The North East region has vast potential of producing better crop quality and fulfilling the needs of the people in this field as the scope for emerging market is there.
