Water Usage in Paper Mills

According to Mr. Elhardt's study, the paper industries such as Printing and Writing (P&W) and Newsprint are on the of the charts in water consumption compared to other grades, consuming over 9 million gallons per day (MMGD) on average, with the market pulp industry coming at a whopping average of over 17.5 MMGD ( See Figure 1 ).


Apart from flour milling, energy consumption data in this sector was very sparse. Between 2005 and 2015, an average of 0.42 MJ/kg of electricity and 0.03 MJ/kg of fuel was reported for the milling process ( Appendix A ). Rice required the least amount of energy and was quoted to consume 0.43 MJ/kg in 2013.
