Biogas

Biogas is a type of biofuel produced naturally from the decomposition of organic matter. The gas is formed when micro organisms break down the waste in a closed environment without oxygen, this process is also referred to as anaerobic digestion. This digestion releases gas which is liquified to Liquid Biogas ( LBG ).

If paper can do this, it can do anything

We have made it our business to push the boundaries when it comes to renewable materials and sustainability. Helping you decrease your footprint and meet your green targets by creating innovative solutions that make way for a fossil-free future. Together we are changing the game.

From residue to fuel

We are converting residue from the process water into liquefied biogas – LBG – a renewable fuel mainly used for heavy-duty vehicles. The expected LBG production of the plant is 75-90 GWh per year – an amount, which would keep more than 200 average long-haul lorries running for a whole year.

Yet another advantage

This initiative to cooperate for the good of the planet is something extraordinary, but at the same time, making use of the residue from our production is just one example out of many. Yet another advantage that proves the point, Multicopy is the only office paper you need. While taking you closer to your green targets – without compromises on performance or quality – Multicopy is generating the drive you need to make a difference.

Finding the most innovative, sustainable solutions calls for partnering with like-minded experts

Energy company Gasum, have built a biogas plant at Stora Enso’s Nymölla paper mill in Sweden (where Multicopy is produced). The plant, built and operated by Gasum, turns the mill’s residue water into renewable energy – Liquefied Biogas (LBG).

Gasum are the leading supplier of biogas and processer of biodegradable waste fractions in the Nordic countries. Gasum promote the circular economy by processing organic waste and producing biogas and recycled nutrients.

This is how we do it

Transforming residue water into fossil free fuel

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 minus 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 using LBG instead of diesel, the greenhouse gas emissions can be reduced by up to 90%.

“We are happy to be part of a project that will turn waste into valuable renewable energy. For Stora Enso, substituting fossil-based fuels in our society with renewable solutions is a vital way to combat global warming. The cooperation with Gasum is a good example of the collaborative efforts Stora Enso is taking to do this.”
