In our pursuit of international competitiveness we have selected Elemental Chlorine Free technology while modernizing our front line.

We are first paper/board mill in India to adopt this technology sourced from Metso (shown in figure). The facility was commissioned in Sep’2002, at a cost of USD 50m and is ahead of government regulators and norms.

Highlights

• Elimination of elemental chlorine in bleaching
• Cleaner, brighter and stronger pulp
• Energy efficiency
• Increase in capacity to 100,000 TPY
• Reduction in water usage

Process

A two stage oxygen delignification helps in reducing kappa number of the unbleached pulp by 45%. Chlorine dioxide is used in bleaching & eliminating chlorine and hypochlorine. The bleach sequence followed is D1 – Eop – D2.

Alongwith the fiber line a new chemical recovery boiler with a time efficiency electrostatic precipitators, falling fiber evaporator and a line sludge reburning were also commissioned.

Benefits

AOX load reduced to 0.65 kg/T of pulp. Reduction in BOD & COD levels. Reduction in volume of effluent discharge.

Raw Materials : Integrated Pulp Mill

Equipped with batch digesters to cook Bamboo, Eucalyptus, Casuarina, and mixed hardwoods. Pulping is based on Kraft process and can deliver 100,000 TPY of bleached/unbleached hardwood pulp. A D1-Eop – D2 sequence is used at the bleaching stage, which delivers pulp of 88 degrees ISO brightness.

Secondary Fibre Treatment

Two separate plants are available to feed imported pulp and recycled paper. Hot dispersion unit assists in delivering a cleaner recycled pulp.

Chemical Recovery Unit

Evaporation plant, Soda Recovery Boilers fitted with Electrostatic Precipitators and Dorr-Oliver Recausticizing unit constitute the chemical recovery unit, which achieves 96% efficiency.
