Pulp and Paper Manufacturing Industry

A CLEAN SHEET OF PAPER REQUIRES A CLEAN PROCESS

Paper manufacturing involves many chemical processes that drive the emission of nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon dioxide (CO2). Nitrogen dioxide and sulfur dioxide are major contributors of acid rain, whereas CO2 is a greenhouse gas responsible for climate change. In addition, wastewater discharge for pulp and paper mills often contains alcohols, chelating agents, and inorganic materials like chlorates and transition metal compounds. Furthermore, chlorine and compounds of chlorine are used in the bleaching of wood pulp, especially chemical pulps produced by the kraft process or sulfite process. Even if your pulping operation no longer uses chlorine for bleaching, you may still need to control chlorine dioxide emissions from operations or reduce sulfur emissions from paper processing.
