Raw Material Requirement for Sustainability of the Industry
    Agro Based Mills
    • Wheat straw & bagasse will be the mainstay raw material for the sector.
    • By 2010 , agro based fibre requirement to meet the demand would be 7.0 million tons.
    • Availability of surplus bagasse for paper industry is only 10 million tons and difficult to be increased under present operational conditions of sugar mills.
    • Wheat straw availability is sufficient (22 million tons) therefore further expansion should be expected to be based on wheat straw.
    Recycled Fibre
    • By 2010, the recycled fibre requirement to meet the demand will be 6 million tons.
    • If the present recovery rate is enhanced from 18% to 25% by 2010, availability from indigenous sources will be 1.5 million tons and 4.5 million tons will have to be met through imports.
    Challenges before the Recycled Fiber Based mills
    • The availability of good quality waste paper at competitive price
    • There is a need to take immediate measure to organize the existing waste paper recovery system to increase the recovery rate from present 18% to 30% to be sustainable.
Technology Improvements Needed
    Wood Based Mills
    • Enhancement in productivity through adoption of advanced production techniques such as RDH/Super Batch.
    • New and efficient pulp washing systems should be adopted.
    • ECF bleaching with ClO2 followed by peroxide is recommended .
    • Enzyme bleaching should be adopted to reduce chemical cost and discharge of chloro organics.
    • Breast roll and blade gap formers improve paper quality and drainage and are important for Indian raw materials.
    • A good press section is important in India because fibers are short. Extended nip is the only good solution for Indian slow machines. One shoe nip press section would be the best technology.
    • Unsupported web run is normal in Indian dryer section when speed is higher than 600 meters/min, there should be single tier dryer groups to avoid web flutter and breaks.
    • Soft calendar are highly recommended and they could save bulk and improve opacity, strength and smoothness however this requires good CD profiles.
    • Films coaters and on-line calendars are recommended with good CD profiles.
    • Soft roll rewinders might be a low cost alternative to improve roll quality of this paper or coated papers.
    • Process automation level must be improved.
