With its WoodRoll technology, the Swedish technology company Cortus Energy has built a biogas plant at Höganäs AB which is the very first of its kind in the world. WoodRoll is based on existing technology combined into a new and innovative system, which means a groundbreaking approach to gasifying biomass. The whole process takes place in a closed system in which the insulation is essential to safeguard the output. Operations at the plant are planned to start in 2019.
“Paroc is very happy to have supplied insulation to this unique plant,” says Håkan Glöckner, Paroc’s manager for the project. “We need to get the industry to switch to green alternatives and reduce CO2 emissions. This is just the beginning and a clear demonstration that Paroc is committed to the move towards sustainability.”

Höganäs AB
Höganäs AB is a world leader in the iron and metal powder market with an annual capacity of 500,000 tonnes. Its iron powder is used in various types of industrial manufacturing and is found in some 3,500 products, such as bicycles, sewing machines and aeroplanes. Coal is currently used to heat the furnaces at the plant. Coal, which is a fossil fuel, will now be partly replaced by the green biogas. The steel industry’s climate roadmap presents biofuel as a key piece of the puzzle in achieving fossil-free production by 2045.
“For Höganäs, switching from fossil fuels to renewable energy is part of our long-term strategy. To succeed, we need to get involved, invest resources and take the lead in exploring new opportunities,” says Nicklas Lång, Senior Vice President Sustainability at Höganäs.
Cortus Energy
Cortus Energy is a Swedish technology company that was founded in 2006. The plant in Höganäs, which they will also own for 20 years, is their first one in commercial use. It has a capacity of 6 MW and the plan is to scale up to 20 MW. The unique WoodRoll technology they have developed is based on three process steps:
1. Drying. Biomass (wood chips, bark, branches, etc.) are dried
2. Pyrolysis. The heated biomass forms a pyrolysis gas and char (pieces of a substance similar to barbecue charcoal)
3. Green biogas. The char is pulverised and injected with water vapour (1,100°C) and green biogas is formed. The finished biogas is then cooled down and ready for use.
The biogas consists of:
Construction
The construction company Bilfinger, which specialises in industrial operations around the world, is responsible for building the plant.
“There was never any doubt about choosing insulation from Paroc because we’ve had very good experiences with them in the past,” says Morgan Vestlund, project manager at Bilfinger. “Paroc’s Pro Wired Mat 100 is ideal for the industry and the strict requirements that must be met. In this plant, where both hot and cold pipes need to be insulated, reliable products are essential to safeguard operations. A project of this nature requires fast and flexible solutions, and Paroc have always delivered on time.”
PAROC Pro Wired Mat 100 is a non-combustible stone wool mat with a hot-dip galvanised wire net on one side. Applications include thermal insulation of boilers, pipelines, containers, etc. The product is recommended in strenuous environments that experience e.g. high temperatures and vibrations.
The plant has been approved by the certification company Kiwa to start testing of natural gas. This will take place in the spring of 2019.
