ABSTRACT
Pulp and paper raw materials are in huge demand due to the growth of the pulp and paper sector in Pakistan and around the world. Because of scarce forest resources and abundance of agricultural leftovers, Pakistan has a great opportunity to produce pulp and paper utilizing raw materials of non-wood. In nations where the supply of wood for this industry is declining, the utilization of non-wood for pulp and paper production has increased. Three groups of raw materials are used in the manufacturing of paper: non-wood, wood, and recycled wastepaper. Utilization of non-wood resources in pulp manufacturing have several advantages, including easier pulping, lower energy use, the preservation of forest reserves and improved management of agricultural waste. The use of fibers of non-wood plants in paper production is also linked to a number of issues, such as collection, transportation, challenges of chemical recovery, alteration of morphological properties and slow water retention. The main consumers of non-wood fibers, small mills, usually have poor pollution control systems. Non-wood materials are now a more viable option as raw materials for papermaking due to a number of considerations. Several pulping methods can be used for non woody raw material such as soda/soda anthraquinone and organosolv. The availability and utilization of raw materials of non-wood for Pakistan’s pulp and paper sector is examined in this study. Non-wood fibers offer a variety of physicochemical characteristics that make them a viable raw material substitute for Pakistani pulp and paper manufacturers.
