A unique pilot plant is under construction at Stora Enso Sunila Mill
A pilot plant that will produce renewable bio-based carbon is currently being built at Sunila Mill in Kotka, Finland.
Synthetic graphite, a non-renewable material commonly used in batteries, can be replaced by converting lignin separated from wood into carbon-based anode materials for lithium-ion batteries. Stora Enso has been producing lignin industrially at Sunila Mill since 2015. The annual production capacity is 50 000 tonnes, making Stora Enso the world’s largest producer of kraft lignin.
The pilot plant construction will be completed at the beginning of 2021.
