Converting pulp and paper industry waste into advanced materials and product
Conversion of black liquor from the kraft process of a Eucalyptus pulp and paper mill factory into pure lignin. Then pure lignin will be used as sustainable raw material for green processes able to generate promising added-value compounds products such as fibre precursors
The use of waste components from industrial activities as raw materials to obtain high value-added products is of increasing interest. Lignin from the pulping process is present all over Europe and represents a big source of underexploited material. There is an estimated 70 million tonnes of lignin available from pulping processes worldwide, but much of this is not isolated but burned onsite to provide steam for heat and power production. Until now only about 2% of the lignins available in the pulp and paper industry is commercially used. Lignin is also a component of forestry arisings and wood processing facilities. EUCALIVA aims to create a valorisation chain of the lignin fraction, using Eucalyptus waste as a source. EUCALIVA, focused on three fundamental aspects of lignin preparation. This included (i) optimised lignin separation and preparation and the manufacture of lignin-based fibres; (ii) development of efficient and faster thermostabilisation routes; (iii) development of carbon fibres and other carbon-based materials with enhanced properties.
The global lignin market is expected to account for USD 2.88 billion by 2029.
Waste black liquor from pulp industry has been converted to high value biobased chemicals which will decrease environmental footprint.
The project will develop a community around the social networks to be in contact with stakeholders and the general public contributing to Europe’s economic growth and job sector in pulp and paper sector
