Why? Pulp mills provide raw materials for several applications, many times competing with or replacing fossil-based products. The versatility of the products they offer puts them in a strategic position when considering the transition towards a bio-based economy.  Thus, a good understanding of the pulping process, specially kraft pulping, is essential to ensure the future

Why? When considering potential alternatives to fossil-based products, pulp mills play an important role, as they can supply a wide range of renewable materials and chemicals. In order to ensure a sustainable growth of the pulp industry, it is essential to tackle challenges, such as increasing pulping efficiency and decreasing raw material consumption[1]. In this

Why: Efficient pulp washing successfully balances the highest quality of pulp, the removal of soluble impurities and dissolved solids to the evaporation plant. Optimal usage of washing water minimizes the load for the evaporation plant and simultaneously lowers the need for bleaching chemicals and effluents to the environment. Therefore, measuring the washer’s performance is vital

Why? The pulp and paper industry has the potential to be a major player in the change towards a bio-based circular economy. With its currently wide selection of available products, as well as promising new alternatives derived from side streams, it can aid in decreasing the production and consumption of fossil-based material. Yet, it faces

Why? Establishment of the LignoBoost technology has enabled recovery of kraft lignin on an industrial scale and opened up for increased utilization of lignin building blocks in materials and chemicals. The essence of this technology is a CO2-precipitation of lignin followed by dewatering and a final wash after an additional acidification (Fig 1). Filtration properties
