The new liquid biogas plant at Nymölla mill was commissioned on 27 April 2021, and it is a major milestone in the mill’s long history as a sustainable operation. The plant is the culmination of a successful partnership with energy company Gasum.
Instead of going to wastewater treatment ponds, the mill’s process water will be diverted to the LGB facility co-located at the mill. There it is used to feed microbes that produce biogas which is collected and cooled to liquid form.
Before the biogas setup, the inherent value in the process water was ending at the bottom of ponds. Now it can power a bus around the world every day of the year. In addition to reducing heavy vehicle carbon emissions by 90% compared with diesel, LBG produces far fewer particulates, lowering vehicle impact on air quality.
Customer queries about environmental impact have been growing exponentially for Stora Enso. The discussions have moved on from materials and processes to addressing the big picture of sustainability, how to reduce impact on the planet and achieve circularity.
While the Covid-19 pandemic delayed the biogas project, it has also raised climate awareness.
