Abstract: The Indian paper and pulp industry is considered to be one of the oldest industries in India. In
the recent past, importance has been given to increasing energy efficiency as it is an energy
intensive industry. With the launch of the PAT scheme, 31 large paper and pulp mills are
required to save 1,12,421 MTOE in the three years.
An extensive literature survey has shown 60 measures and technology options to reduce energy
consumption. A questionnaire survey was conducted of 15 papers and pulp DCs. In this study,
eight technologies have been identified which are most commonly used by the paper and pulp
DCs interviewed. Four of these have also been found in the literature survey.
A correlation has been found between the annual paper production and a few parameters. There
was a positive correlation between annual paper production output of the mills and their annual
energy consumption, and also between the annual paper production output and the percentage
of energy saved by the energy efficient measures taken by the mills themselves. A negative
correlation was seen of the SEC as a function of the paper production output. This analysis
showed that annual energy consumption, SEC and percentage of energy saved by the mills were
significantly related to the paper production output.
