Wood – paper – biogas! For a fossil free future

As the renewable materials company, Stora Enso is constantly aiming to push the boundaries of sustainability. Sometimes, finding the most innovative sustainable solutions calls for partnering with like-minded experts.

To help you reach green targets and decrease your footprint, we have partnered with energy company Gasum to establish a biogas plant at Nymölla paper mill in Sweden. The plant, that is built and operated by Gasum, is converting residue from the mill’s process water into liquefied biogas (LBG) – a renewable fuel, mainly used for heavy-duty vehicles. The gas from this plant will fuel more than 200 average long-haul lorries for a whole year, while reducing their greenhouse gas emissions by up to 90% compared to diesel.

Generating the drive you need to make a difference

This joint effort to move towards a fossil-free future is some¬thing extraordinary. But at the same time, making use of the residue from our production is just routine – one example out of many. Because this is how we like to do things at Stora Enso; always looking for ways to add more value and to decrease negative impact on the planet. In addition, the biogas plant is one more benefit proving Multicopy’s qualities as the most sustainable choice, without compromises on performance or quality. A premium office paper that is generating renewable energy and the drive you need to make a difference.

This is how we do it


1. It all starts with a tree growing in a sustainably managed forest.

2. Our wood is mainly sourced within a 100km radius and taken to Nymölla mill.

3. In the process of turning wood into premium office paper, water is gradually removed in both the pulp and paper making process.

4. A stream of residue water is pumped into a reactor where biogas is produced after organic materials are broken down by bacteria in an oxygen-free environment – a process called anaerobic digestion. The biogas is then cooled down to -160C° and turned into liquefied biogas.

5. The LBG is stored in an insulated tank before it’s pumped to trailers and transported to gas stations where it’s used to fuel heavy-duty vehicles.

6. By fueling trucks with LBG instead of diesel, the greenhouse gas emission can be reduced by up to 90%.
