SmartLi

Smart Technologies for the Conversion of Industrial Lignins into Sustainable Materials

Summary

Currently, almost all aromatic chemicals and building blocks originate from fossil fuels like oil. Lignin is a phenolic natural polymer with the potential to replace these non-renewable resources.

SmartLi will develop valorisation routes for lignin, creating materials – notably composite materials and resins - with the potential to replace those that presently depend on fossil raw material sources. Importantly, it will source them from underutilised lignin by-products from pulp and paper industry.

SmartLi will add value to the underexploited biomass sidestream lignin and deliver quality homogeneous raw materials for users. At the same time, it will reduce dependence on fossil fuel based raw materials and enhance sustainability by reducing greenhouse gas emissions.

Description

Objectives: 
  • Develop and demonstrate technologies and processes to use technical lignin (kraft lignins, lignosulphonate and bleaching effluents) as raw materials to produce biomaterials, such as components with improved properties for composites, plasticisers and different types (PU, PF, epoxy) of resins.
  • Replace oil-based product by bioproducts from lignin (e.g. to substitute 25-75% of phenol in formaldehyde resins, to replace at least 50-70% of polyols in polyurethane foams).
  • Perform a Life Cycle Analysis to assess the economic, environmental and social sustainability of the developed products and identify a strategy for market penetration.
Expected impacts: 
  • Development of applications for technical lignins which are presently not valorised and which allow the replacement of fossil-based products in 4 product categories: thermoplastic composites, PF resins, PU foams and epoxy resins.
  • Facilitation of market penetration of these bio-based products in the respective sectors with high demand, thereby creating business opportunities and jobs.
  • An expected reduction of 20% in GHG emissions.
