The RISE institutes Innventia, SP and Swedish ICT have merged in order to become a stronger research and innovation partner for businesses and society.
During 2017 will be one of several websites within RISE. Please visit for more information about RISE.

LignoDemo test bed for upscaling

The demonstration plant in Bäckhammar opened in 2007 with the aim of demonstrating the LignoBoost process. The plant is owned and operated by the subsidiary LignoDemo AB.

There is a daily production of high quality lignin in the plant. Innventia carries out assignments for clients wishing to evaluate their own black liquor or the lignin product from it. It is also possible to perform large-scale product- and process development at the LignoBoost Demo plant.

Within the regional initiative LignoCity, the demonstration plant is being further develop to an open test bed for companies who want to evaluate and validate new refining concepts in the lignin area.

LignoCity - The cradle of bioeconomy. 

LignoDemo demonstration plant start-up

The LignoDemo plant can produce up to 8,000 tonnes of lignin per year, which is used for large scale trials. For example, the lignin fuel has been used in long-term trials (2007-2008) to replace coal at the Fortum combined cycle heat and power plant in Stockholm. Another example is full-scale trials in a lime kiln in Sweden where replacement of fossil fuel was evaluated. 

Bäckammar demonstrationsanläggning för LignoBoost
With support from Fortum Värme, Nordic Paper, Stora Enso, Södra Cell and the Swedish Energy Agency the LignoDemo plant has been in operation next to the Bäckhammar pulp and paper mill since January 2007.
