Engineering a sustainable world

Produced by ITN Business, part of one of the UK's leading television news organisations, this short film offers a glimpse inside Europe's largest single-site biorefinery and the innovation behind our operations.

What is a biorefinery?

At Pannonia Bio, sustainably sourced corn and barley are transformed into a range of high-value products through an integrated biorefining process.

Using proprietary front-end fractionation technology, we separate these grains into their natural components and maximise the value of every fraction.

The starch is used to produce bioethanol, a lower-carbon alternative to fossil-based petrol. The protein is transformed into high-value food and animal nutrition ingredients. The oil is used in feed applications, while the fibre contributes both to animal nutrition and the production of renewable natural gas.

From fueling vehicles to producing renewable natural gas, protein-rich animal feed and high-value food ingredients, we create sustainable solutions that fuel tomorrow and feed change.

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:

Large-scale industrial systems
Modern automation solutions
Energy efficiency projects
Biotechnological processes
Sustainability innovations
Complex engineering challenges
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. Expect a mix of desk-based engineering, time in the plant or pilot facilities, and discussion with your supervisor.

You will be solving real engineering problems. You might run a calculation, prepare a drawing, produce and analyse trial data or investigate a performance trend. You will have one main assignment with agreed objectives, regular feedback and a final report and presentation.

The scope will reflect your experience, placement duration and the work underway when you join. You will receive site induction and training for your tasks.

You will collaborate with our Engineering, R&D and Maintenance teams as relevant to your assignment, learning howplant engineering, process development and equipment reliability contribute topractical improvements.

    Closer than you think

    ~50 min

    by car from south Budapest

    Our Dunaföldvár plant is about a 50-minute drive from the southern edge of Budapest with commuting support.

    Who is it for?

    We primarily welcome master’s students and final-year bachelor’s students from:

    • Chemical engineering
    • Bioengineering
    • Mechanical engineering
    • Electrical engineering
    • Mechatronics engineering
    • Energy engineering
    • Environmental engineering
    • Process engineering
    • Automation and control engineering
    • Industrial digitalisation and data analytics

    But for us, the name of your degree isn’t what matters most.

    We’re looking for talented students who are curious, love solving problems and are keen to put what they’ve learned into practice in a real industrial environment.

    Engineering internships at Pannonia Bio

    Process and Chemical Engineering

    For Chemical Engineering BSc and MSc students with a process engineering focus.

    Work with process engineers on capital projects, plant optimisation and scale-up – from distillation and evaporation to drying and fermentation.

    What you'll do

    • Build mass and energy balances, size equipment and compare design options.
    • Prepare PFDs, P&IDs and equipment specifications, and review supplier information.
    • Analyse plant data to improve yield, capacity and energy efficiency, and support plant trials.
    • Turn pilot results into design inputs, weighing safety, utilities and feasibility.

    Your project might be a concept design from pilot data, a feasibility study or a process improvement plan.

    Paid placement, with commuting support to our Dunaföldvár site.

    Biochemical Engineering

    For Biochemical Engineering BSc and MSc students (especially Applied Biotechnology) and Biotechnology MSc students interested in fermentation and bioprocessing.

    Join Process Development or R&D, linking microbiology and engineering through fermentation and pilot plant projects.

    What you'll do

    • Design experiments and run trials, from sampling and monitoring to lab analyses.
    • Analyse how yeast, enzymes, feedstocks and conditions affect fermentation and yield.
    • Prepare material balances and tackle scale-up questions like mixing and heat removal.
    • Present results and recommendations – evidence that can support your dissertation.

    Your project might compare fermentation conditions, test a grain-derived sugar stream or assess a pilot process before scale-up.

    Paid placement, with commuting support to our Dunaföldvár site.

    Mechanical Engineering

    For Mechanical Engineering BSc and MSc students interested in process equipment, piping, maintenance or project management.

    Join Project Delivery or Maintenance, working with engineers, project managers and maintenance specialists on installation and reliability.

    What you'll do

    • Prepare layouts, piping routes, isometrics and bills of materials in Autodesk Plant3D.
    • Help specify and install process equipment, pipework and valves.
    • Support project managers with schedules, contractors and progress reporting.
    • Join site surveys, installation checks and commissioning.
    • Plan preventive maintenance and investigate recurring equipment failures.

    Your project might design an installation package for a pump or heat exchanger, coordinate a work package to handover, or solve a recurring equipment failure.

    Paid placement, with commuting support to our Dunaföldvár site.

    Energy Engineering and Industrial Utilities

    For Energy Engineering BSc and MSc students focused on industrial energy use, thermal engineering or renewables.

    Work with process engineers and the utilities team on energy efficiency and heat recovery across steam, cooling water, refrigeration and compressed air.

    • Prepare heat and energy balances and compare energy use across unit operations.
    • Assess steam demand, cooling loads and utility losses through on-site measurements.
    • Evaluate heat recovery, heat pumps, vapour recompression or biogas options, with savings and costs.
    • Estimate utility needs and payback for capital projects.

    Your project might assess waste heat recovery, evaluate a cooling system or build an energy balance for a new installation.

    Paid placement, with commuting support to our Dunaföldvár site.
