Composition Of Waste Paper Sludge

Environmental impact of paper

In the United States the pulp and paper industry released about 79 000 tonnes or about 5% of all industrial pollutant releases in 2015 Of this total waste released by the pulp and paper industry in the U S 66% was released into the air 10% into water and 24% onto land whereas in Canada most of the waste (96%) was released into the air
