Known for its authentic cheddar, Jukolan Juusto sought new ways to utilise the whey generated as a side stream in its cheese production. These opportunities were explored through a hackathon held on 10 February 2026. The five selected teams presented ideas ranging from high‑protein drinks and snacks to research on the antimicrobial and immune‑supporting properties of whey. The winning solution came from Aircohol, which uses whey as a growth medium for microalgae and plans to refine the algae for applications such as cosmetic ingredients.

The Jukolan Juusto Hackathon was organised as part of the FinFoodNet project, which aims to boost the growth of Finnish food exports by strengthening cooperation between regions and companies.

One of the project’s activities was to organise a co-creation event for companies aimed at strengthening export readiness. For this purpose, the proven BioBoosters Hackathon concept was utilised, and the challenge was framed around exploring how side streams could be processed into export products.

Jukolan Juusto, a cheesery from Leivonmäki, offered the hackathon a concrete example: the whey generated as a side stream from its cheddar production. Each week, roughly 2,500 litres of whey ended up being used to improve soil on nearby fields, but Jukolan Juusto wanted to find a higher‑value application for this high‑quality, protein‑rich raw material. The hackathon served as a tool to explore new applications and suitable collaboration opportunities. 

At the hackathon’s kick‑off event, the five selected teams were introduced to Jukolan Juusto’s operations, the competition’s evaluation criteria and potential export opportunities. The programme also included a presentation by Lotta Westerlund from the German‑Finnish Chamber of Commerce, who outlined opportunities in the German market as well as key considerations when developing an export product for Germany. 

On the hackathon day, held at the Bioeconomy Campus in Saarijärvi, the teams refined their concepts with support from multidisciplinary experts. The event concluded with a series of pitches presenting new opportunities for whey utilisation in food products, cosmetics and scientific research. 

From whey to algae for the food and cosmetics industries

Aircohol Oy, a company specialising in algae cultivation, won the competition with its concept Algae <3 Dairy Whey.

“Our idea is to grow microalgae in whey. The algae take up the nutrients, sugars and trace elements in the liquid. The algae can then either be used directly or refined into smaller components that can be applied in the food industry or in cosmetic products,” explains Sara Makkonen, commercialisation associate at Aircohol Oy, who presented the pitch.

“Competition was extremely strong. Aircohol offers an innovative solution that fits current trends, and there is already customer interest behind it. Most importantly, the concept is highly scalable and we see real potential for it in the future,” says Jukolan Juusto’s Managing Director, Markku Liias. “We will continue close cooperation and start building a broader package together.”

The jury also gave special mentions to two research teams. A joint team from the Universities of Jyväskylä and Tampere proposed studying antimicrobial compounds in whey and its possible immunological benefits, with potential applications in the pharmaceutical sector. LUT University presented a concept for refining surplus whey into various biocomposite applications through separation and processing technologies. Jukolan Juusto expressed its full support should either research project proceed. The remaining teams in the competition were Foodiq and Juustokievari.

The event Jukolan Juusto Hackathon – From Side Stream to Export Product was organised as part of the FinFoodNet project, which supports the export of Finnish food solutions. The project develops an inter‑regional network, “Finnish Food Cities and Regions”, which strengthens cooperation within the food sector between cities, RDI organisations and companies. The participating innovation cities are Seinäjoki, Jyväskylä, Lahti, Kuopio, Turku and the Helsinki Metropolitan Area. The project is carried out by Into Seinäjoki, Jamk, LAB University of Applied Sciences, University of Turku, Savonia University of Applied Sciences, University of Helsinki and the City of Vantaa. It is co‑funded by the European Union. The hackathon was arranged in collaboration with Jamk's Circular Bioeconomy Business Accelerator BioBoosters.
