The Indian paper manufacturing sector consumes approximately ____________ kWh of electrical energy to produce one ton of paper?
Show answer Hide answer
Answer: C. 1400
Explanation
Indian paper manufacturing mills consume an average of approximately 1400 kilowatt hours per ton. Pulping and paper drying operations require intensive electrical and thermal energy inputs. Improving energy efficiency in paper mills remains a major focus for industrial sustainability engineers. Paper production involves debarking, chemical pulping, refining, sheet forming, and extensive thermal drying. Electrical energy powers large motor-driven refiners, agitators, pumps, and high-speed papermaking machines. Specific energy consumption varies depending on raw materials used like recycled paper versus virgin pulp.
Energy audits help paper manufacturing facilities identify opportunities to reduce high electricity consumption. Industrial energy efficiency reduces operating costs and lowers greenhouse gas emissions in pulp mills. Benchmarking energy consumption drives technological improvements across the global paper manufacturing sector. A consumption figure of 300 kilowatt hours is far too low for complete paper manufacturing. 800 kilowatt hours underestimates the electrical energy required for intensive pulp refining and drying. While some older mills consume higher amounts, 1400 kilowatt hours is the standard benchmark figure.
