Our paper plants had a GE gas turbine that provided power and the waste heat was used to dry the paper. It was a neat setup, and they sold power back to the utility. One of our plants was over 1.5 miles long, I drove the car and measured it. That includes a lot of warehouse space. When we toured the warehouse I saw the little rail cars and thought it near they had half sized rail cars in the warehouse.
They weren't half sized.
The last I knew a new tissue papermachine cost over $350 million. We had six at the plant I toured. The paper we use in printers and whatnot is quite different.
