About the project
The L1X project led by Lixea will scale up the technology and build a first-of-its-kind production plant in Slovakia. The plant will process 25 000 tonnes of biomass per year and produce cellulose, lignin and furfural which will be used to replace fossil-based materials in diverse application areas, including moulded fibre and packaging solutions, thermoplastics and resins.
Impact of the project:
The biorefinery plant aims to produce high-quality cellulose, lignin, and furfural from residual biomass, resulting in the estimated avoidance of 526 360 tonnes of CO2 emissions over the course of 10 years.

Spinverse’s role
Spinverse experts worked together with Lixea in all aspects of the proposal preparation, including project concepting, GHG calculations, business plan and feasibility study, leading to success in the highly competitive Innovation Fund call. After the positive outcome, Spinverse also supported Lixea in the Grant Agreement process.
.
Spinverse was an invaluable partner in reaching the next big milestone in our venture to turn the vision of sustainability into everyday reality for us all. Their patience and dedication helped to translate our complex, deep-tech proposal into a successful grant application - they were team members in every sense, and we are grateful for their expertise and support. We very much look forward to working with the team again in the near future!
