If one had to pick a single technology that has had the greatest impact on improving pulp quality while also improving environmental performance, it would undoubtedly be ODL.
Naini Papers did a lot of in-house R&D to create this technology to meet the needs of an agro-based pulp mill. Initially, this technology was employed in pulp mills that utilized wood as a raw material. Incorporating this technology into an agro-based pulp mill was a first for Naini. The process and equipment engineering was done in-house in collaboration with Sulzer, a world-leading business that supplied the technology's crucial equipment.
The following are the key benefits of ODL:
- 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
