Finnish renewable and bio-packaging supplier, Stora Enso Oyj, has developed bio-based Lingin as a replacement for oil-based phenolic materials.
Branded under LineoTM the materials can be used in resins for plywood, oriented strand board (OSB), laminated veneer lumber (LVL), paper lamination and insulation material.
Lignin has been previously used to produce plastic- and polyurethane-like materials.
In a 13 Feb statement Stora Enso said it had already been producing lignin at industrial scale since 2015 at its Sunila Mill in Finland, which has a production capacity of 50 kilotonnes per annum.
Stora Enso said is already selling LineoTM to replace phenol, and is also looking at other applications for the versatile material.
A stable, free-flowing brown powder, Stora Enso’s lignin is separated during the Kraft pulping process of Nordic softwood.
LineoTM has a high dry content, superior dispersibility and long storage time.
