Atria is one of the leading food companies in the Nordic countries, Russia and the Baltic region. The group is divided into four business areas: Atria Finland; Atria Scandinavia; Atria Russia; and Atria Baltic.
Atria Finland develops, manufactures and markets 100% Finnish fresh meat and other foodstuffs, and provides related services. It is the market leader in Finland’s slaughterhouse industry and has significant export operations.
Atria is planning to build a large biogas and Nutrient Recovery and Re-use (NRR) plant in Seinäjoki (Finland), a region (in a radius of 50 km) characterised by intensive primary production, Atria group slaughterhouses, and other lands where digestate (derivates) can be spread. A-farmers, part of the Atria Group, has been responsible for the first steps of this enterprise.
A-farmers has also been involved in the SYSTEMIC project since its beginning in 2017 and the Seinäjoki biogas plant will be considered a key SYSTEMIC outreach location.
Drivers for nutrient recovery
Atria seeks to enhance the competitiveness of Finnish meat on the global market, as well as the environmental sustainability of primary production and the whole food-production cycle.
Valorising manure into recovered products would enhance A-farmers’ primary production in the neighbourhood of slaughterhouses and prepare Atria for stricter rules for spreading manure/digestate in the future.
The growing season in Finland is short, with less than two months in the year when spreading of digestate makes sense, since spreading into frozen land is not allowed, nor useful. Throughout the remainder of the year, the produced digestate needs to be stored, requiring a strong storing capacity.
Atria considered that digestate spreading as such is not enough for substantial nutrient recycling, neither from the environmental, nor the economic point of view, and will therefore place nutrient recovery at the heart of the new plant.
The plant will treat manure, slaughterhouse waste and biowaste, and will have an estimated treatment capacity of 164 000 tonnes/year at the beginning (the environmental permit will allow for a total of 240 000 tons/year).
Nutrient recovery technologies
The produced biogas will be around 10 Mm³/year or 70 GWh, with the goal to upgrade and generate Liquefied Biogas (LBG) to be used as fuel for heavy traffic. The amount of LBG produced is estimated at 50 GWh. The plant’s own energy – electricity and heat – will be produced through Combined Heat and Power (CHP).

Benefits of the NRR plant
The construction of the NRR plant will allow for:
- Less than 50% of incoming material to be stored and transported, resulting in reduced costs and emissions;
- Concentrated nutrient products to be transported economically to areas in need of nutrients, resulting in optimised use of excess nutrients and reduced emissions to surface and ground water;
- Nutrients to be used in a more sustainable way, such as for valuable, quality nutrient products being used according to plant needs, again resulting in reduced emissions to air and water;
- Approximately 200 m³ of water to become available for recycling and discharging on site as this water does not have to be transported as diluted digestate or treated as waste water;
- Fresh water need is very low: decreased costs of fresh water and waste water.
Benefits of participating in SYSTEMIC
“We look forward to exchanging knowledge with specialists and other plant operators.
Atria has experience with evaporators and membrane technology and has conducted field tests and analyses on digestate and recovered products, including organic harmful compounds.
From the consortium and other plant owners, they would like to learn more about the different nutrient recovery technologies, especially feedstocks that could cause technical problems, technical issues related to operation and maintenance, and the maturity of the technologies now and in the future.”

State-of-play of the plant
- Environmental assessments have been made for 360 00 tons/year;
- Pre-agreements exist for the land of the plant;
- The zoning process started in November 2017 and is still ongoing, but expected to be legalised in June 2019;
An environmental permit for 240 000 tons/year was applied for in February 2018. The process was complicated due to strong resistance within the neighbouring areas, resulting in a need for modifications to the application, including a possibility to apply for a discharge permit at a later stage.
New requirements for Best Available Techniques (BAT) in Finland necessitate extensive evaluation of compliance to be performed by Atria, which additionally slows down the permit process.
The environmental permit is expected to be granted in June or July 2019 at the latest.
- The final tendering and detailed negotiations, and concept planning are being agreed in early 2019.
- The final financial agreements are being made and negotiations with energy customers (pre-agreements for 80% of LBG), raw material suppliers and nutrient product users are being finalised in early 2019.
- The final investment decision is due in the summer of 2019 and Atria is planning to start the construction in the summer or autumn of 2019. It is estimated that the plant would be operational the first quarter of 2020.
