Scandinavian Biogas is one of Sweden’s largest private producers of biogas


We are identifying new projects for further expansion. Current operations are in Sweden, Norway and South Korea.

Core expertise

Our biogas plants: striving to be the most effective solution

Scandinavian Biogas supports customers and partners with what we do best, designing and operating biogas plants with high level of resource and energy efficiency. Furthermore, we strive to improve the efficiency of all our plant on an ongoing basis.

Increased production capacity through efficiency

At Scandinavian Biogas we keep our promises and take long-term responsibility. Proof of this are the plants that we operate in Sweden and South Korea. Indeed, at the Swedish plants in Bromma and Henriksdal we have increased the volume of fuel grade biogas an entire 21 percent in three years and have been able to maintain production at a high level. In South Korea our plant at Ulsan is instrumental in solving the city’s environmental problems with food waste. We have increased the management and processing of food waste from the city of Ulsan with more then 500%. As a result, the plant has been ranked by the South Korean authorities as the country’s most efficient biogas facility. The food waste that is now turned into biogas was earlier dumped into the ocean.

Qualified expertise with high level of competence

Our core expertise is to develop concepts for resource efficient, high loaded, stable biogas processes where organic waste and residual products are used as substrate. We either own or co-own the biogas facilities that we design and operate, adding value with our qualified expertise in the field of biogas production. Our strength lies in developing resource and economically efficient processes for many different types of substrate. These process concepts include the whole chain from designing biogas plants to the management, pretreatment and digestion of organic material as well as the upgrading of biogas to vehicle fuel grade quality. What differentiates us from many others in the industry is our deep knowledge of the biological process and our focus to use that to fine-tune the digestion process. Years of research and evaluation have resulted in a database covering more than 300 substrates.Our qualified expertise in biogas production enables us to:

» Produce more gas per mdigester volume
» Achieve greater stability in the reactor during the digestion process
» Provide qualified knowledge on a wide range of substrates
» Upgrade the gas with extremely low methane leakage
» Achieve effective cost and resource efficient production
» Constantly increase the biogas capacity by process improvements

Integrated solutions: from waste to valuable bioproducts

In Sweden, our biogas production plant at Södertörn is Stockholm County’s first industrial facility for the digestion of food waste. During 2016 the facility extracted energy from 50,000 tonnes of food waste, corresponding to one year’s worth of waste from almost 700,000 Stockholmers. Biogas is produced by converting food waste into renewable bio gas and high­quality bio­fertiliser. Due to the plant’s efficiency, nearly 80 per cent of food waste energy is converted to biogas.

Greater efficiency

Better biogas yield


The improvements made by Scandinavian Biogas to the biogas process in the digestion of sewage sludge could potentially translate into a fourth fold increased biogas production.


Lean and efficient production

Scandinavian Biogas has primarily focused on improving the mesophilic process, where production takes place in a temperature between 35 to 40 degrees Celsius. The company has made substantial steps forward in research & development, including the evaluation of over 300 types of organic material as substrate for biogas production. Furthermore, the company has developed robust processes that accommodate high loads in the reactor, enabling production levels far more efficiently and economically than has previously been possible.

Projects & operations

Projects & operations

Our operations focus on industrial level production and we possess leading expertise in the design and operation of biogas plants to achieve consistently high levels of biogas production, generated through our resource and energy efficient processes. Biogas projects are managed in close cooperation with private and municipal stakeholders in the Nordic region, particularly in east central Sweden, which is the company’s main market today. In addition, Scandinavian Biogas produces biogas in South Korea.

Our history

Our history


Erik Danielsson establishes UltraSonus with headquarter in Öregrund, Sweden, 1996.


UltraSonus initiates tests on the effect of ultra sound on biogas production together with Tekniska Verken in Linköping. The tests are managed by Tekniska Verkens Process manager Jörgen Ejlertsson and UltraSonus CEO Ola Ödmark.


The company later named Scandinavian Biogas is founded by Erik Danielsson, Jörgen Ejlertsson and Ola Ödmark. At that time, these far-sighted pioneers knew nothing of the financial crises and technical setbacks that they would face, nor did they know that the company would eventually become one of Sweden’s leading suppliers of biogas.


Scandinavian Biogas is commissioned to increase the capacity for digestion of food waste in the South Korean city of Ulsan. The food waste to be treated had earlier been dumped into the ocean. The two entered a collaboration, encompassing a concession agreement with a term of 15 years. The representatives of Scandinavian Biogas reached an agreement with politicians in the city of Ulsan and the company’s assignment was to design a considerably improved biogas production process at the Youngyn biogas plant as well as assuming responsibility for plant operations for the term of the agreement.


Former Swedish Prime Minister Göran Persson replaces Erik Danielsson as Chairman of Scandinavian Biogas. In conjunction with this, Erik Danielsson is appointed honorary chairman of the company.


Following extensive improvement in the production process at the Youngyn biogas plant in Ulsan, South Korea, both reactors are deployed. Furthermore, Scandinavian Biogas acquires Stockholm Vatten’s facilities for the upgrade of raw biogas at Bromma and Henriksdal with the goal to improve the amount of biogas available on the Stockholm gas market.


The Scandinavian Biogas production plant in South Korea was named the country’s most effective facility, an award that generated great interest among politicians and media. Thanks to the Scandinavian Biogas plant, Ulsan is one of the few South Korean cities to successfully adhere to new legislation prohibiting the dumping of food waste in the sea.


In early March, Scandinavian Biogas entered into an agreement with SRV Återvinning AB to construct a new biogas plant at Gladö Kvarn, Södertörn. The objective is to process food waste from five municipalities south of Stockholm, converting it into fuel grade biogas. The project will help expand the availability of renewable fuels in the region.


On the 2nd October, the Chairman of Scandinavian Biogas, Göran Persson and Sweden’s Minister of Energy, Ibrahim Baylan inaugurated Södertörns new biogas plant. This means that the Stockholm County with just over two million inhabitants now has its first industrial biogas plant for food waste. This will also mean that local production of biogas in Stockholm County is going to increase by at least 50 percent.


Scandinavian Biogas investments in a biogas project at Norske Skogs pulp mill Skogn, Norway and acquires majority stake in Biokraft Holding AS. The new line for upgrading of biogas at Henriksdal is taken in operation and is inaugurated on April 28th, by the Stockholm Environment Deputy Mayor Katarina Luhr and Stockholm County Traffic Council Kristoffer Tamsons.
