Pulp and paper mills have large boilers which are used to supply energy for making paper. This energy is normally supplied by wood waste, however, wood varies substantially in heat values and moisture content, so the mills often supplement the wood fuel with other fuels,such as coal or oil, to make the operation more stable.
In this study, the thermal decomposition profiles of the blends of paper mill sludge and a typical semi-anthracite coal were evaluated under pyrolysis and combustion conditions and compared with those of paper mill sludge and coal. The effect of the sludge weight percentages on the overall combustion characteristics of the blends was also analyzed.

Paper mill by-products include coal and wood ash, along with "fines" or fibers that are too short to be made into paper products, and residue from operating wastewater treatment plants. Pulp and paper mills have used these materials for many years landspreading wastewater residues as a soil amendment on farm and forest lands, drying and ...
Mercury discharges were studied in the environment of five pulp and paper mills. The US pulp and paper industry does not use mercurials anymore. Still, its main raw materials contain mercury as contaminant. The most significant airborne mercury discharge occurs through burning of coal (1-2 lb of Hg/1000 ton of pulp).
Jun 10, 2015· Experts say that steam rates are comparatively low and that selling steam to one customer is not a good use of ratepayer funds. "If you're a paper mill and put in cogeneration to provide your plant electricity and steam, that's an ideal arrangement," said Renew Wisconsin program and policy director Michael Vickerman.

International Paper Brazil Facilities Lead the Way on Solid Waste. In Brazil, where our fiber is supplied by eucalyptus plantations grown near our mill, land application of composted pulp and paper mill residual waste materials returns organic matter and nutrients to the very land that produces the mill's primary raw material.
But many paper mills have historically been big buyers of outside energy as well, either electric power or fuels, such as coal and natural gas, burned in a mill's own boilers.
