Before the 1970s, wastewaters from the pulp and paper mills were normally discharged directly to the rivers or lakes, without any treatment or even a rough primary treatment.
  • Why is the pulp and paper industry a polluting industry?
  • The pulp and paper industry generates vast amounts of wastewater, and its character heavily depends on various factors (raw material, the undertaken process, the final product, etc.). The wastewater from this sector, which originates from several sources in each mill and are mostly combined, is polluting and hazardous.
  • How to remove contaminants from paper & pulp industry?
  • Biological methods can be used to remove contaminants from the wastewater obtained from the paper and pulp industry ( Paździor, Bilińska, & Ledakowicz, 2019 ). Such treatment methods are more environmentally friendly and use plants/microbes or enzymes.
  • How to manage pulp and paper mill waste?
  • Three different approaches can be used in pulp and paper mill waste management. The first choice is to minimize waste in ensuring product efficiency, higher yield of materials, and lower waste management (Mladenov and Pelovski 2010). The second choice is to find a suitable way for reuse to maintain cost improvement and lower environmental approach.
