Why lignin-based carbon fibre? Demand for cost-efficient carbon fibres. Biobased is a plus Increased replacement of steel with carbon fibre composites in cars Decreased weight and fuel/electricity consumption of the car fleet GreenLight idea Utilize lignin, a wood component that is a large by-product from pulp mills, as raw material for such cost-efficient and green carbon fibres.

GreenLight Project goal Demonstrate the viability of the processing of lignin into carbon fibre (CF) and CF structural composites with customized features (lightness, strength, costeffectiveness) for the automotive industry that can replace the CF produced with petroleum-based raw materials. Budget 2.6 M (Financing: 50% EU, 50% Södra) Coordinator Innventia Duration 1 July 2015-30 June 2019 This project has received funding from the Bio Based Industries Joint Undertaking under the European Union s Horizon 2020 research and innovation programme under grant agreement No 667501
