  • How can the pulp and paper industry reduce environmental impact?
  • For instance, in Finland the pulp and paper industry has succeeded in decreasing their environmental impact significantly during the past 20 years by applying biological water treatment and by closing the water circulation.
  • What are the applications of membranes in the pulp and paper industry?
  • One of the most studied applications for membranes in the pulp and paper industry is the purification of the strongly colored effluents from bleached kraft pulp mills. The first alkaline extraction stage effluent is a good example of a stream whose environmental impact is remarkably high compared with its volume.
  • Is process water reuse a problem?
  • Facing the fact that process-water reuse is limited by the accumulation of dissolved matter from raw materials (wood or recycled paper and fillers), and chemicals entering the process, is nowadays among the key challenges of pulp and paper mill management [ 20 ].
  • What is water reuse in pulp & paper industry?
  • In fact, it is considered as a reference model for water reuse applications in industry. Although pulp and paper industry is still an intensive water user, only a 5–8% of the water that is used in the process is actually consumed, whereas the remaining 92–95% returns back to water streams or networks after its proper treatment [ 2, 3 ].
