Pollution Prevention: Chlorinated Pollutant
Releases From the Pulp and Paper Industry Martha G. Prothro*
The pulp and paper industry is a major manufacturing segment in the United States;over 600 mills are
operated by 265 firms, employing approximately 160,000 people. The industry is the nation's largest manufacturing category in terms of value of shipments (currently in excess of$120 billion annually).The industry is also a major source of

tants emitted to the air and 34% dis
charged to water. The majority of the 370 million pounds of TRI pollu tants discharged by the industry (1988) are chlorated organic chemi cals such as chloroform. The U.S. Environmental Protec
tion Agency is using a multi-media approach to dealing with the envi ronmental problems created by this industry. At present, seven major Agency initiatives are underway to control pulp and paper industry dis charges to the air, water and land. At the heart of these efforts is a
focus on pollution prevention as the optimal mechanism for reducing, if not eliminating, these discharges. For example,EPA's revised effluent guideline regulation for pulp and paper will reflect wastewater treat ment systems and manufacturing processes based on no- and lowchlorine pulp bleaching technolo gies. While the industry has taken many steps to reduce chlorinated pollutant discharges, much remains to be done to further reduce intro duction of these chemicals to the environment.
