Lignin fractionation and separation to produce different technical lignins

Lignin valorisation can be a crucial step for lignocellulosic biorefinery concepts to reach economic figures. This necessitates the development of technologies and processes to efficiently purify and process lignin for further utilization. LIFT builds on the developed process from the FocusLab AP³ - lignin separation by precipitation - and will further develop this technology. Different lignin materials will be processed and characterised. Linking their compositional data to the fractionation process data will identify suitable strategies to produce different types of lignin.

What is the relevance and the impact for the Bioeconomy?

The transition from a petroleum based to a bio-based economy necessitates the development of novel solutions to produce functional materials, commodities and fuels. Holistic approaches to use lignocellulosic biomass derived from agricultural waste streams, such as demonstrated in the FocusLabs AP³ and Bio², display promising alternatives to build up novel biobased value chains. As several studies indicate, lignin valorisation in these concepts can become a crucial step to reach economic figures. Therefore, LIFT is of high impact for the Focus Topic Area “Integrated biorefineries for sustainable production and processing” and especially relevant for the FocusLabs HyImPAct, Bio² and AP³. Currently, only few concepts to separate technical lignins with high oxygen content and conserved functionality are available. Therefore, LIFT further develops and evaluates the feasibility of the lignin separation and purification concepts established in AP³ towards broader range of substrates and higher mechanistic understanding. Both are prerequisites for an implementation into a holistic biorefinery concept.
