If one has to identify single technology that has contributed maximum towards the improvement in pulp quality along with the improvement in environmental performance, it will certainly be ODL. Naini developed this technology to suit the requirement of agro-based pulp mill by doing lot of in-house R&D. Initially, this technology was used in wood-based pulp mills. Naini was pioneer in adapting this technology in an agro-based pulp mill. The process and equipment engineering was carried out in-house in consultation with world’s leading company Sulzer, which supplied the critical equipment for this technology. The main advantages of ODL are as below:

  • Reduction in COD of bleach plant effluent by 35%
  • Reduction in chlorine consumption by 35 to 40%
  • Improvement in the brightness of pulp
  • Improvement in strength properties of pulp
