Biogas glossary: What’s what in the biogas sector

In June we published an article about the biogas plant that is under construction at Nymölla paper mill in Sweden. A joint effort by Stora Enso and Gasum to turn residue from our production of Multicopy into renewable fuel – LBG. But what is biogas and what does the different abbreviations stand for? Here’s a brief what’s what.

• Biogas
A type of biofuel that is naturally produced from the decomposition of organic waste, typically from the food industry and agriculture, but now also from paper production.

• Anaerobic digestion
The process of making organic matter break down in an environment absent of oxygen (=anaerobic) is also known as anaerobic digestion.

• LBG – Liquefied Biogas
The type of gas that will be produced in the plant at Nymölla Mill. Biogas is transformed into liquid by being cooled down to -160°C°.

• Environmental benefits
Switching fuels in the heavy-duty vehicles segment, from diesel to liquefied biogas (LBG) or natural gas (LNG), will reduce greenhouse gas emissions by up to 90%. And also have a significant impact on reducing levels of particulates and noise.

Other terms that are good to know:

• Natural gas
Natural gas is sourced from natural gas and oil deposits as well as shale rock found deep in the earth’s crust in terrestrial and maritime areas.

• LNG – Liquefied Natural Gas
A clear, colorless, non-toxic liquid that forms when natural gas is cooled down. LNG offers a cleaner alternative for maritime and road transport, as well as industries.

• CNG – Compressed Natural Gas
Made by compressing natural gas down to less than 1% of its volume. It can be used in place of gasoline and diesel fuel in cars and commercial vehicles.

• CBG – Compressed Biogas
Biogas can be compressed after removal of Carbon dioxide, the same way as natural gas is compressed to CNG, and used to power motor vehicles.

• Circular Economy
A circular economy is an economic system aimed at eliminating waste and the continual use of resources.

Paper brings people together

Paper has played an important role for humans for centuries. Even though our world becomes more and more digitalized, paper still has plenty of functions in our everyday lives.

In a way, paper helps us link to the physical world – and connect with the ones we hold close. Let’s look at how!
