Biogas plant contact details


Gasum owns a nationwide network of biogas plants. Our local biogas plants provide services related to biodegradable waste processing, biogas production and production and distribution of recycled fertilizers.

Gasum’s objective is to actively develop the Nordic gas ecosystem.

In December 2016 Gasum purchased 100% of the shares of the Swedish biogas producer Swedish Biogas International. The transaction made Gasum the biggest producer of biogas in the Nordic countries.


Turku region biogas project expansion moving ahead

Gasum Ltd’s biogas project in Turku is moving ahead as progress is being made in design work and procurement.The project comprises the expansion and modernization of the Topinoja biogas plant in Turku, and the construction of a biogas upgrading and liquefaction plant.As part of the project, Gasum will also construct more filling stations to serve light vehicles in the Turku region.The expansion project will be completed during 2019.

The total investment of the Turku biogas project will create a significant new opening in growing the biogas business. The Finnish Ministry of Economic Affairs and Employment has granted the Turku biogas plant expansion €7.97 million in investment aid for key energy projects.

“Developing the biogas market and increasing production are a core part of our strategy. The Topinoja biogas plant expansion project in Turku includes the modernization and expansion of the biogas plant processing capacity, biogas upgrading and liquefaction and partly compression. The end product of reject water treatment will be high-quality nitrogen concentrate which we will supply to our customers. The liquefaction of biogas will make it possible to distribute biogas for use as a fuel for heavy-duty road as well as maritime transport. The liquefaction capacity will correspond to the annual fuel consumption of around 125 heavy-duty vehicles. In addition, we are able to supply compressed bio gas for car traffic in the Turku region. Liquefied biogas is available from our four heavy-duty vehicle filling stations, located in Turku, Helsinki’s Vuosaari Harbor, Jyväskylä and Vantaa. We’ll also be constructing more stations,” says Matti Oksanen, Director, Product Management and Solutions, Biogas, from Gasum.

The Turku project will provide around 170 full-time equivalents of employment during the construction phase.The annual total capacity of the biogas plant following the completion of the expansion will be around 110,000 tonnes of sewage sludge and separately collected biowaste as well as industrial side streams.The project will enhance the growth of the Finnish biogas market and strongly promote the transport fuel use of biogas. Construction of the Topinoja project is underway and will be completed in 2019.

Under the Government Programme, the key projects aim to bring the Finnish economy to a path of sustainable growth and rising employment. The objective of the ’Bioeconomy and clean solutions’ key projects is to increase the use of renewable energy in a sustainable way so that its share will rise to more than 50% during the 2020s. This will be based, in particular, on the growth in the supply of bioenergy and other emission-free renewable energy.

Gasum receives investment grant from Swedish Environmental Protection Agency for biogas production from industrial waste waters

The Energy company Gasum is evaluating the possibilities to produce biogas at a large scale from industrial waste waters off the Stora Enso Nymölla Pulp and Paper plant in Sweden. The aim for Gasum is to produce biogas primarily for use in the transport sectors in Sweden. Gasum has been granted an investment subsidy for the Nymölla project of €12.4 million (SEK 121.5 million) by the Swedish Environmental Protection Agency under the Climate Leap (‘Klimatklivet’) program. Gasum’s vision is to build a Nordic gas ecosystem where the circular economy is at the core.

Gasum is in the finishing stages of a study regarding the production of biogas from waste waters off the Stora Enso Nymölla Pulp and Paper plant in the south of Sweden. The aim for Gasum is to produce biogas that will be upgraded and liquefied for use primarily in the transport sectors in Sweden. Gasum foresees rapidly increasing demand for liquefied biogas in the Swedish heavy duty vehicle sector as well as in the maritime transport sector.

Gasum’s Nymölla project has been granted an investment subsidy of €12.4 million (SEK 121.5 million) by the Swedish Environmental Protection Agency under the Climate Leap (‘Klimatklivet’) program.  

The total investment volume of the project is around €27 million and Gasum is now proceeding into the investment decision phase of the project.

”We’d like to thank the Swedish Environmental Protection Agency for the positive investment support decision. This will support our efforts to make the circular economy reality with the Stora Enso Nymölla Pulp and Paper mill. The biogas plant will be a sustainable solution for the processing of waste water”, says Markus Olsson, Managing Director of Gasum AB.

Gasum and partners process waste and produce biogas in Finland and Sweden. Gasum is the leading producer of biogas in the Nordic countries. Biogas is a domestic biofuel made from fully renewable raw materials and is a versatile energy source.

Renewing energy company Gasum develops Nordic gas market

Renewal is a key element of Gasum’s strategy. In the past few years, the company has grown from a Finnish natural gas company to a Nordic energy company building the LNG and biogas markets in the Nordic countries while at the same time looking after the competitiveness of natural gas in Finland. Good leadership and management, employee wellbeing and safety and security are important to Gasum. Gasum wants to develop these continuously together with the personnel. These themes have been adopted as focal areas in the company’s human resource management.

On November 9, 2017 a letter was sent by shop stewards of Gasum personnel groups to the shareholders and the Board of Directors of Gasum Ltd. The shop stewards acted independently in this and did not contact their respective personnel groups about the letter or its contents. In response to the views presented in the letter, Gasum has provided the shareholders with a report on the measures taken so far to develop good leadership and management and employee wellbeing.

An extensive workplace community survey will take place in the Gasum Group. The survey will be conducted by the consultancy company MPS during the final weeks of the year. Gasum management takes the concerns raised in the letter about the company’s workplace and cooperation atmosphere seriously and finds it very important to look into the matter as regards the entire Gasum Group.
