Elias Hakalehto Interview
When many think of innovation, microbes are rarely the first thing that comes to mind. But for Dr. Elias Hakalehto, microorganisms are not just tools or subjects of study—they are essential collaborators in solving the world’s pressing problems. Founder, CEO/CSO of Finnoflag Oy, Adjunct Professor, author, inventor, lecturer—Hakalehto wears many hats, and each is marked by a consistent vision: that harnessing the microbial world is critical to environmental health, industrial process, and human well-being.
From Student Activist to Global Thought Leader
Hakalehto’s journey began with a strong academic foundation. A microbiologist trained at the University of Helsinki, and with further studies in the United Kingdom (University College London, University of Kent at Canterbury, Westminster), he early on combined academic rigor with environmental activism. While still a student in the early 1980s, he was deeply involved with Helsinki University’s student union and helped establish its environmental section. Their projects—household recycling, biological agriculture, recycled paper use—weren’t merely theoretical: they reflected a life-long commitment to sustainability.
His doctoral dissertation, published by the University of Kuopio in 2000, focused on bacterial cell surfaces and their functions—laying scientific groundwork for the innovations to come.
Finnoflag Oy: Innovation at the Intersection of Microbiology and Industry
Since founding Finnoflag Oy in 1993, Hakalehto has led more than 150 R&D projects across research, industry, clinical, environmental, and food sectors—both in Finland and internationally. The company has become known for:
- PMEU (Portable Microbe Enrichment Unit): This patented technology improves sampling, pre-enrichment, transportation, enrichment and detection of microbes. It accelerates microbiological diagnostics in water systems, food, hospitals, industrial hygiene, probiotic development, and more.
- Industrial & Environmental Microbiology: Applying microbes not just in containment or exclusion, but in transformation—turning waste streams and side-streams into useful resources. Biorefinery projects converting agricultural, forest, or industrial side-streams into energy, chemicals, soil improvers are central to Finnoflag’s work.
- Health, Hygiene & Diagnostics: Monitoring antibiotic-resistant strains, enhancing methods for detection of pathogens, development in probiotic strategies, and exploring the interplay between the microbiome and human disease.
Global Engagement, Publications & Thought Leadership
Hakalehto’s influence extends far beyond Finland:
- He is an Adjunct Professor at both the University of Eastern Finland (Biotechnical Microbe Analytics, since 2008) and University of Helsinki (Agroecological Microbiology, since 2016).
- Vice President of the International Society of Environmental Indicators (Europe & Africa) since 2015, including serving as chairman of their Helsinki conference in 2017.
- A well-published scientist & innovator: over 100 scientific articles, 100+ book chapters, editorships of scientific books, ~80 original patents. His work spans food safety, diagnostics, biotechnology, environmental microbiology, and biorefining.
Vision: Ecosystems, Circular Economy & Microbial Collaboration
What sets Elias Hakalehto apart is not only depth of science, but a holistic, ecosystem-oriented mindset:
- He sees microbes not merely as items to control, but collaborators in metabolism, ecosystem services, human health. His repeated emphasis is on co-operation with microbes, understanding microbial communities, and combining that understanding with engineering, biotechnology, process innovation.
- Circular economy and biorefinery are more than buzzwords—they are tangible projects turning waste into value: chemicals, soil improvers, and renewable energy.
- Health is integral: from diagnostics to probiotic effects, from hygienic monitoring to exploring microbiome-related autoimmunity and nutrition interplay.
Recent Achievements: Real-World Impact
Some recent examples of his work making concrete impact:
- In the Hiedanranta region in Tampere, microbial biorefinery has turned ‘zero fibre’ (formerly underused waste materials at lake bottoms) into valuable chemicals like lactic acid and mannitol, also generating energy gases.
- Record-level productivity: In lab scale, Finnoflag achieved 8 g/L/h of 2,3-butanediol, a platform chemical important across industries.
- Educational influence: Over five decades of teaching, repeated collaborations with universities, designing courses, lectures (locally and internationally), helping train the next generations of environmental engineers, microbiologists, and bioprocess scientists.
Facing Challenges & Driving Forward
Despite having an impressive track record, Hakalehto’s path has involved overcoming “built-in resistance to new thinking” and the perennial gap between academic insight and industrial implementation. He believes success comes from rapid translation of innovations to real-world use, from grassroots R&D, and always keeping an eye on both sustainability and economic feasibility.
The Future: What’s Next
Elias Hakalehto’s outlook is ambitious yet grounded:
- Scaling up biorefinery and circular economy projects to full industrial scale, especially producing platform chemicals, energy gases, soil improvers from side-streams and waste materials.
- Deeper integration of microbes into health and medicine: more precise diagnostics, probiotic strategies, understanding microbial interactions, autoimmunity, nutrient uptake, and more.
- Expanding PMEU-based technologies in more domains: water safety, industrial hygiene, food safety, environmental monitoring, with faster, more sensitive microbial detection.
Why Elias Hakalehto Stands Out
In summary, what makes Elias Hakalehto exceptional is the synergy he creates among scientific research, industrial application, environmental stewardship, and public health. Few combine:
- Deep microbiological expertise (membranes, bacterial surfaces, metabolism, diagnostics)
- Invention and patenting, translating science into tools (PMEU etc.)
- Real-world industrial projects with measurable outputs (chemicals, energy, soil improvements)
- Global visibility through publications, teaching, leadership roles
Together, they position him as a key actor in biotechnology’s next frontier—where microbes are allies in solving climate, health, waste, and food security challenges.
