Lignin business development with Valmet

Feasibility studies

A study is an ideal way to start building knowledge. Valmet can assist in clarifying the feasibility and options for lignin extraction, identifying the main lignin characteristics, and developing ideas for possible business opportunities.

Production of lignin samples

Valmet has small lignin extraction units that can be relatively easily set up in a pulp mill. These units produce up to a few kilograms per day.

Small-scale production of lignin provides valuable information on the lignin qualities that can be produced at the mill, possible lignin markets and options for lignin extraction.

Lignin extraction for commercial verification

Pulp producers who want to explore the lignin business can do so with LignoBoost XS, a small-scale LignoBoost plant with a capacity of up to 500 tonnes of lignin per year. The plant is delivered in modules for easy transportation and installation.

The latest LignoBoost XS was delivered to Mercer.

The first company to install LignoBoost XS was Klabin. Read more about that delivery here.

More information on LignoBoost XS can be found here.

Commercial scale plants

Valmet has built two commercial scale lignin extraction plants.

The picture to the right shows the LignoBoost plant at Domtar Plymouth mill, USA.

The biggest LignoBoost plant Valmet has built to date was delivered to Stora Enso’s mill in Sunila, Finland. This plant was designed for 50,000 tonnes of lignin per year. Sunila wanted to be able to use the lignin that was not sold as fuel in the lime kiln and Valmet's delivery therefore included a lignin dryer as well as equipment for handling and transporting lignin.
