Stora Enso launches Lineo – a lignin replacement for oil-based phenol
Lignin is one of the main building blocks of a tree and makes up 20-30 percent of the composition of wood. It is derived as a by-product of pulp and paper processing but its use as a raw material has been limited. Recognising its potential as a bio-based feedstock, Finland-headed global forest industry major Stora Enso has launched "Lineo", a renewable bio-based replacement for oil-based phenolic materials.
The recently launched lignin product is a renewable replacement for oil-based phenolic materials which are used in resins for plywood, oriented strand board (OSB), laminated veneer lumber (LVL), paper lamination and insulation material.
Having increased our lignin focus in recent years, we’re delighted to launch Lineo. Lignin is a non-toxic raw material with a traceable origin and stable cost structure, and bio-based Lineo is ideal for companies looking for alternatives to oil-based products. We believe that everything made from fossil-based materials today, can be made from a tree tomorrow, commented Markus Mannström, Executive Vice President of the Stora Enso Biomaterials division.
Stora Enso has been producing lignin at industrial scale since 2015 at its Sunila Mill in Finland. The mill’s annual capacity is 50 000 tonnes, making Stora Enso the largest Kraft lignin producer in the world. The company is already selling Lineo as a replacement for fossil-based phenol, and the company is also looking at many other applications for this very versatile material.
A stable, free-flowing brown powder, Stora Enso’s lignin is separated during the Kraft pulping process of Nordic softwood. According to the company, “Lineo” has a high dry content, superior dispersibility and long storage time. With a higher reactivity and purity, the product is consistent from batch to batch and Stora Enso can supply different levels of dryness, according to customer demand.
