Benchmarking Paper Mill Energy Efficiency and GHG Emissions - Fisher I

Paper mills are fairly large consumers of thermal and electrical energy. Thermal energy is used mostly to dry paper by way of steam. Efficient use of energy is certainly an integral part of good paper mill operation. Greenhouse gas emissions (GHG) are closely linked to overall energy usage, but also depend upon types of fuels used.
