Lignin, a waste product in biomass and ethanol production, now finds new value as bio-oil in new products. At the University of Borås, Sweden, a team of researchers has investigated methods to extract and refine lignin for industrial applications.

While the commercial lignocellulose-to-ethanol plants use lignin after pretreatment as biomass feedstock to heat and power plants, in the Horizon 2020 project AGROinLOG, lignin is instead transformed into bio-oil-based products.

The researcher Swarnima Agnihotri has spent a year at the University of Borås refining the methods to extract the lignin from lignin-rich wheat straw. She says, "If biofuels are to become a reality, we need to realize the industrial potential of lignin and get more value from it. Seeing the complexity and richness of its functional groups, there are various potential applications of lignin by converting it in variety of value added products like high performance carbon fibre, bio-oil and vanillin, to name a few."

The project uses an agricultural residue, wheat straw, which is available in surplus in Sweden, and also in other European countries.
