Wood is a composite of cellulose fibers embedded in lignin, a natural glue that keeps the fibers together. Every year, more than 70 million tonnes of lignin pass through the world’s chemical pulp mills.
LignoBoost®, Valmet’s lignin extraction technology, makes it possible to extract lignin from pulp mill black liquor. Lignin is quickly becoming a valuable and renewable raw material in a wide range of industries.
There are four LignoBoost plants in operation today. The Valmet-built LignoBoost plants in Finland and the USA are built for commercial production and have a combined design capacity of 75,000 tonnes of lignin per year.
Valmet has also recently built a smaller LignoBoost plant in Brazil. This plant extracts smaller amounts of lignin that is used for experiments and small-scale production of different materials and products.
LignoBoost is a proven and reliable technology that has been developed with several industrial partners. The world’s first LignoBoost plant was built by RISE (then Innventia).

Extracted lignin can be tailored to match the intended end use. This is done with lignin tailoring processes developed by Valmet and its industrial partners. The tailoring processes can be supplied with new LignoBoost plants or installed as upgrades to existing ones.
