Livestock farms in the region benefit from the biorefinery in many ways. The most significant benefit is that slurry and dry manure generated on farms are processed into digestate. Compared with raw manure, digestate is more uniform in quality, and its nutrients are in a form that is readily utilised by plants. Farms can purchase digestate in the form that best suits their needs.

Odours are reduced when the gasifying compounds in manure are removed in the biorefinery. Hygienisation of manure destroys pathogens, weed seeds and mould spores.

At the same time, the farm’s emissions are significantly reduced, as methane emissions from slurry storage are eliminated and the nutrient cycle becomes more controlled. The nutrient load of the Archipelago Sea is reduced.

Reducing emissions throughout the production chain supports sustainable agriculture. Individual livestock farms will be better equipped to meet future environmental requirements, access better financing and develop their operations. Conditions for business continuity will improve.

When manure processing is centralised at a biorefinery, manure volumes no longer limit the farm’s expansion.

How is manure transported from the farm?

We handle transportation at no cost to farmers. Hygiene is carefully maintained: after each farm, equipment is washed and disinfected to prevent the spread of animal diseases from one farm to another.

How do you ensure that animal diseases are not spread via the transport vehicles?

The transport equipment used for manure and digestate is washed and disinfected after each farm.

How do you prevent the spread of diseases that may be present in raw materials in a biorefinery?

The digestate is hygienized by heating it to a temperature of at least 70 degrees for an hour. This destroys pathogenic bacteria and weed seeds, preventing their spread.

What criteria do you use for farms to be included?

The farm must have separate collection and return points for manure and digestate. Manure collection will primarily be carried out using full trailer trucks, which must have year-round access to the collection and return points.

How do I know whether the manure produced on our farm is suitable as a raw material for a biorefinery?

Pig, cattle or poultry manure is generally suitable as a raw material for a biorefinery. The refinery does not process municipal sludge or fractions containing plastic.

The best way to ensure the suitability of manure is to contact us. We are currently preparing letters of intent for raw materials.

How can we get involved? Will all interested farms be able to join the project?

You can join by contacting us! Letters of intent are currently being prepared. As of now (1/2026), we have already secured 400,000 tons – so there is still capacity.

Manure is sourced from within a radius of max 70 kilometres of the biorefinery.

Where is manure sourced from?

Manure is sourced from within a radius of max 70 kilometres of the biorefinery. The source distance depends on the raw material quantity and energy content.

Will the farms receive compensation?

Raw material sourcing models are currently being developed. The starting point is that cooperation with the biorefinery is economically viable for farms. We cover collection and logistics costs, saving farms money on transport. Digestate can be returned to a different location from where manure is collected.

If we need a new retrieval or collection well for the farm, is support available?

Support can be applied for from the Finnish Food Authority. Joint well projects with neighbouring farms are also possible.

The biorefinery offers crop farms an opportunity to improve their profitability. We purchase field biomass, including crop rotation residues, surplus grass and green manure crops. This means crop rotation plants can also generate direct income rather than being a cost to the farm.

Crop rotation improves the growth conditions of the field. The soil structure improves, the humus content increases, and the activity of microorganisms increases. Greater diversity also reduces risks from weeds and diseases.

Improved growing conditions lead to better crop security and more stable yields over time. By making crop rotation economically viable, the biorefinery supports farms’ sustainability and profitability. In addition, farms have access to digestate and recycled fertilisers produced by the biorefinery.

What type of field biomass does the refinery purchase?

Various waste and residue masses are suitable for the biorefinery, including straw, crop rotation and surplus grasses, plant residues, spoiled crops and other plant biomass fractions.

It is important that the inputs delivered to the biorefinery do not compete with food or feed production.

Will farms be paid for field biomass?

Yes. The biorefinery buys field biomass from farms. It is priced competitively from the farmer’s perspective. The idea is to bring additional benefits to the current operating model, which has no use for, for example, surplus grass or residues.

Field biomass is priced based on biogas yield potential and dry tonne. Pricing models will be refined in spring 2026.

Does harvesting field biomass create additional work?

We are developing an operating model where harvesting and transportation of field biomass can be handled on the farmer’s behalf. In this case, the farm will be responsible only for sowing.

Ideally, biomass collection is integrated into existing fieldwork.

Does the farm receive support for cultivating or transporting field biomass?

Yes. However, the goal is to develop an operating model that functions as much as possible on commercial terms and supports sustainable agriculture.

How much field biomass is required for the plant?

According to the planned feedstock distribution, one tenth of the raw materials would be field biomass. In practice, this would amount to around 60,000 tonnes.

How can diseases that may be present in the raw materials be prevented from spreading?

Digestate is hygienised by heating it to at least 70 °C for one hour. This destroys disease-causing bacteria and weed seeds, preventing their spread. The transport equipment used to transport manure and digestate is washed and disinfected after each farm.

How do I know whether our field biomass is suitable as a raw material for a biorefinery?

The best way to ensure the suitability of agricultural biomasses is to contact us. We are currently preparing letters of intent for raw materials.

From which area is field biomass sourced?

Field biomass is sourced within a radius of approximately 40 kilometres of the biorefinery. The source distance depends on the raw material quantity and energy content.

The biorefinery provides the food industry with a concrete way to reduce climate impacts across the production chain. When primary production side streams and manure, as well as the food industry’s own clean side streams, are used effectively, emissions across the entire production chain are reduced. This is directly reflected in the scope 3 emissions of food companies.

The biorefinery’s operating model is transparent and verifiable. It supports companies’ sustainability work and reporting while strengthening the resilience and security of domestics supply chains.

The biorefinery helps the entire food chain operate more sustainably and with lower emissions.

What types of food industry side streams does the refinery acquire?

We accept clean food industry side streams, such as raw material residues, process surpluses and other organic side streams generated during production.

The best way to confirm suitability is to contact us. We are currently preparing letters of intent for raw materials.

How will transport from the factories be handled?

Sourcing models and logistics for side streams are defined on a case-by-case basis.

How much field biomass is required for the plant?

According to the planned feedstock distribution, less than one tenth of the raw materials would be food-industry byproducts. In practice, this amounts to approximately 50,000 tonnes.

What are the practical benefits of cooperation for the industry?

Companies receive a responsible and verifiable solution for handling side streams. At the same time, this supports their climate goals and contributes to developing the entire food chain to be lower-emission and more resource-efficient.

For side streams with high energy content, we are also able to pay compensation.
