Management Team

Founder, President & CEO, and majority shareholder Per Lillebø holds a master's degree from the Norwegian Business School (NHH) in Bergen, Norway. He started his career in Norsk Hydro in 1980 and, just a few years later, co-established a profitable business within oil trading, distribution, and marketing. In the following years, he successfully managed and developed several companies within the same industry.  

In 1992, Mr. Lillebø and his partners acquired Cambi, a small research and development company focused on utilising steam explosion technology. This ultimately became the company's core competence as Cambi developed world-leading technologies within the wastewater sludge treatment industry.  

Mr. Lillebø has been instrumental in developing Cambi into a top-tier company within the international wastewater industry and has developed a broad international network over the years. 

Eirik Fadnes became Cambi Group's CEO in 2020 and has vast management experience, having held executive positions in Singapore, Norway, and Argentina. He has worked at KOP Surface Products, industrial investment company Aker ASA, and multinational auditing firm Ernst & Young.  

Mr. Fadnes holds a Master of Science (MSc) degree in Economics and Business Administration from the Norwegian School of Economics (NHH) and an MSc in Auditing and Accounting from BI Norwegian Business School.  

Andreas Helland Lillebø started in Cambi in 2014 and currently holds responsibility for sales, technology, and operations. He has worked with project commissioning, technical troubleshooting, improvements to existing plants, and product development within the company. 

He is the principal author of two pending patents, one of which presents a method for reducing energy consumption by 30% using Cambi's thermal hydrolysis process systems.  

Mr. Helland Lillebø holds an MSc and a PhD in Chemical Engineering from the Norwegian University of Science and Technology (NTNU) on the conversion of biomass into liquid fuels and chemicals via the Fischer-Tropsch synthesis method. His PhD included experimental and theoretical work conducted at NTNU and Stanford University in the United States. 

Maarten Kanters leads Cambi’s investment activities, focusing on developing projects where Cambi assumes ownership and operational interests (Design-Build-Finance-Operate projects/Public-Private Partnerships), as well as investing in companies connected to the thermal hydrolysis process technology. An example is daughter company Grønn Vekst AS, the Norwegian market leader for biosolids recycling and soil production.

Maarten joined Cambi in 2017 as VP for Corporate Business Development and has been responsible for project development, Cambi Services, and other strategic initiatives.

Earlier in his career, he had various strategic and project management roles at McKinsey & Company and Yara. Mr. Kanters holds an MSc in Mechanical Engineering from the Delft University of Technology and an MBA from INSEAD.
