Abstract
Industrial sector is the largest user of energy in India and in many parts of the world. The pulp and paper industry accounted for 6% of total global industrial energy consumption, being the fourth largest energy consumer worldwide. For India, energy audit of a paper carton manufacturing unit was earlier reported with the following results. The specific electrical and thermal energy consumption was estimated as 91.85 kWh/ton and 1619 MJ/ton paper respectively. Annual energy saving potential was found to be 5.9% of the total annual energy consumption. With a view to identifying energy conservation and CO2 mitigation opportunities in writing, tissue, and craft paper production, this article presents energy auditing of a paper industry (Orient Paper Mills) in Amlai, Shahdol, Madhya Pradesh, India. The specific energy consumption of the typical paper industry in India was evaluated as 34.3 GJ per ton paper and specific CO2 emissions as 3.4 tons CO2 per ton paper. Some energy conservation opportunities for this industry were identified with significant energy saving (nearly 3.5%) and money saving potential with payback periods not exceeding 2 years in general.

Summary
The industrial sector is the largest user of energy in India and in many parts of the world. Several energy auditing studies have been reported for pulp and paper industry recently. A study on energy conservation in textile industry was reported by Dhayaneswaran and Ashokkumar [8] indicating significant energy saving potential by optimization of motors and process parameters. Madlool et al [9] provided a critical review on energy use in cement industry with recommendations for energy saving through improvements in grinding process and waste heat recovery. To estimate energy use and carbon emissions from writing, tissue and craft paper production in India, the energy auditing of a typical paper industry (Orient Paper Mills) located at Amlai, Shahdol, Madhya Pradesh, India has been presented in this paper. Energy saving opportunities for this industry have been identified through this study
