If you’re an engineering student who wants a close-up look at the industry of the future, let’s stay in touch. Join our talent community and be the first to hear about our internship programmes, professional opportunities and open positions.










What is a biorefinery?
A biorefinery works on the same principle as a traditional refinery: it turns a single raw material into as many valuable products as possible.
Here, sustainably grown corn doesn’t just become bioethanol. Processing also yields proteins, feed ingredients, biomethane, organic soil improver and many other valuable products.

This approach brings together:
- Chemical industry
- Biotechnology
- Energy
- Automation
- Process control
- Data-driven operations
- Sustainability
One site. One system. A real industrial environment.
Work at the world’s most advanced biorefinery
One of the most exciting parts of an engineering career is seeing theory turn into real technology.
At Pannonia Bio, you’ll work in an environment where every day you’ll get hands-on with:
We believe the best professionals grow as active participants, not as observers.
That’s why we aim to offer internships where students can join real projects and make a real impact on our operations.

An international environment with a family-business mindset
Pannonia Bio is part of the Dublin-based ClonBio Group. The company is Irish and family-owned, and its products reach markets all over the world.
In practice, this means you’ll experience:
the professional opportunities of an international company
the stability of family ownership with a long-term outlook
the day-to-day reality of multinational collaboration
You’ll work alongside colleagues from different countries, disciplines and professional backgrounds, all working towards the same goal: building a sustainable future.
Closer than you think
by car from south Budapest
Our Dunaföldvár plant is about a 50-minute drive from the southern edge of Budapest.
Many visitors are surprised by the site’s size, technological complexity and level of innovation. Most don’t expect to find a biorefinery of this scale and technological standard in Hungary.
