Resource-efficient and non-toxic material flows from wood waste

With increasing focus on recycling, wood waste can increase its potential to generate secondary raw materials instead of incineration and landfilling. The quality of wood waste, as determined by the presence of material and mainly chemical impurities, is essential to ensure a high quality, clean and safe recycling loop for particleboards or for other emerging …

Efficient Washing of Paper grade pulp in the kraft process

The project contributes to strengthened Swedish competitiveness through its expected research results and new fundamental knowledge for the development of an efficient pulp washing process and thus through an increased pace of innovation in the transition to a circular economy. After pulping the wood chips, the resulting pulp fibres and cooking liquor are separated in a …

The kinetics of lignin extraction in oxygen delignification.

The current and future environmental challenges call for improved and more sustainable processes in the pulp industry. To contribute to a sustainable and competitive Swedish bioeconomy the pulp industry needs to increase efficiency without increasing the use of hazardous chemicals. Oxygen delignification is a unit process that has been used in pulp mill fiberlines between …

Multi scale modeling of the delignification kinetics during kraft cooking

The kraft process is today the dominant industrial technology for the production of pulp from wood.In this process, wood chips are boiled with chemicals in order to dissolve lignin, hemicellulose andextractives. The process itself contains several complex mass transport mechanisms, where thechemicals are to be transported into the wood chip and then further into the …
