Mill Development Plan (MDP)

The Mill Development Plan (MDP) of TNPL commissioned in May 2008, focuses on improvement of environmental performance of the mill. The MDP involved installation of the following key facilities, at a total capital outlay of Rs.612 crores i.e. 142 million US dollars:

 A 300 tpd state-of-the-art Hardwood Pulp line with Elemental Chlorine Free (ECF) bleaching sequence.
A 500 tpd ECF bleaching plant for Chemical Bagasse Pulp.
 An integrated Chlorine-di-oxide plant of 15 tpd capacity.
 A 1300 tpd Black Liquor Dry Solids (BLDS) recovery boiler along with a 20 MW turbo generator.
A falling film black liquor evaporator of 350 tonnes per hour (tph) water evaporation to concentrate the black liquor upto 70% solids.
Installation of ECF bleaching will make the company to become more compliant towards environmental regulations, operationally efficient besides being cost effective. Post-MDP, the paper production capacity of the mill shall be 245,000 tonnes per annum besides producing 45,000 tonnes per annum of surplus pulp for sale.

Mill Expansion Plan (MEP)

TNPL has now embarked on a Mill Expansion Plan (MEP) involving capital outlay of Rs.1000 Crore i.e. 233 million US dollars. The project aims to increase the paper production capacity of the mill from 2,45,000 tonnes to 4,00,000 tonnes per annum utilizing the surplus pulp generated under the Mill Development Plan already implemented. The Mill Expansion Plan (MEP) involves installation of a state-of-the-art Paper Machine with a production capacity of 1,55,000 tonnes of fine paper per annum, backward integration of ECF bleach plant of Chemical Bagasse Pulp and a multi-fuel boiler with steam generation capacity of 125 tph. Under MEP, the in-house pulp production will be increased from 800 to 880 tpd.

For the MEP, TNPL has placed the orders on M/s. VOITH Paper GmbH & Co., KG, Germany for supply of Paper Machine - 3 and on
M/s. Metso Paper Sundsvall AB, Sweden for supply of equipment for backward integration of 500 oven dried (OD) tpd Chemical Bagasse Pulp ECF bleach plant.

The commissioning for the Mill Expansion Plan is set as June 2010. This will enable TNPL to join the elite group of "1000-plus" (tpd) mills and the company will emerge as the largest Paper Mill in a single location in India.

The MEP includes installation of equipments to address the improvement of environment performance viz. Electrostatic Precipitator (ESP) for the power boiler, additional equipments for effluent treatment plant, oxygen delignification & new brown stock washing equipments at a cost of Rs.126 Crores.

Life Cycle Extension (LCE) of Paper Machine - 1

Apart from adding the capacity, the mill has also taken up life cycle extension programme for the Paper Machine - 1, at a cost of Rs.65 Crore i.e. 15 Million US Dollars. The PM-1, which was installed during 1985, is being equipped with a state-of-the-art dilution control headbox including Profilmatic as well as a wet end retention control system, strengthening of press frames, improvements in the size press, calendar, pope reel and winder. The upgrade will result in improved quality of paper from this machine apart from offering a new lease of life for the machine. Paper Machine-1 was stopped on 16.03.09 as planned and all the LCE jobs were carried out as per schedule. The Paper Machine-1 was put into operation on 15.04.09.

TNPL has a full-fledged finishing house for automatic conversion of reels into sheets and two cut-pack lines to have finely cut and wrapped A4, A3, folio sheets. To capitalize on the growing demand for these papers, TNPL has augmented its cut-pack line capacity to 350tpd with addition of a state-of-the-art 200 tpd cut-pack system from Beilomatik, Germany.

TNPL derives its strength from its dedicated in-house Research & Development (R & D) team, one of the best in the country. TNPL's customer-focused R&D has been instrumental in improving quality, ensuring consistency and introducing new products based on market feedback and needs.
