We are a team of highly qualified, passionate and hands-on engineers, business developers and managers
Meet the SimGas family
The SimGas team in The Netherlands consists of a business development department and a product development department. Together with the operations, sales and marketing teams in East Africa, we deliver groundbreaking products for rural households.
We work from our office in The Hague to design products and make business plans, yet we spend just as much time in the mud, building, testing, and adjusting our systems until our customers are happy. Last but not least, we are good-doers, we are trusting, we are winners, we are trailblazers, and we have fun in just about everything we do.
Sanne cofounded SimGas in 2009. Inspiration for the company emerged from Sanne’s Master’s thesis research, which addressed the feasibility of large-scale biogas systems in Tanzania and Ghana. Sanne is an energy systems engineer focused on sustainable agriculture and energy systems. He manages business activities for SimGas in both the Netherlands and East Africa. Sanne is responsible for SimGas’s international growth and technology implementation.
What’s up with the hat?
You can tell by the hat that Sanne is a true entrepreneur: “If you want to get ahead, get a hat!” And so he did. But he will always take it off to the people he admires: his brother and co-founder, his team, his partners, his shareholders. Such a gentleman.Get in touch via

Lia BardoelDesign Engineer
Lia is an Industrial Design Engineer. She finished her Industrial Design master at the Eindhoven University of Technology in 2013, where she gained a strong interest in product and service design for social entrepreneurship. Her experience on her graduation project on milk cooling for rural farmers in Ethiopia brought her to SimGas, where she is part of the R&D team.
What’s up with the milk churn?
Lia never used to like milk. Until the day that milk practically became part of her job description. Now she can’t live without it. What changed her taste for milk? Fresh, chilled milk, cooled on biogas. Obviously.Get in touch via

She has a strong, personal and professional interest in addressing the fundamental needs of people and their environment in developing and emerging markets from a strategic perspective. Dorine is leading the Business Development team in Kenya with the responsibility of establishing commercial partnerships with over 60 Dairy Cooperatives throughout rural Kenya.
What’s up with the kite?
Dorine could not believe her luck when she stumbled upon a kite festival in India: the sky was filled with colourful kites vigorously held up in the air by millions of people standing on the roofs of their houses and flats. A nation so diverse, can be brought together by flying kites. What a way to have impact!Get in touch via
Oliver is a physicist, gardener, researcher, brewer, patent holder, musician, hang glider pilot (we have yet to discover the things he couldn’t do). With the belief that developing products for the off-grid market in East Africa can teach the world how to live sustainably, Oliver moved to Tanzania in 2010 to start a business in renewable energy products for households. SimGas persuaded him in 2015 to lead our operations in Tanzania and Kenya. Under his wings, a team of more than 90 is making households in East Africa (including his own) happy with biogas.
What’s up with the speakers?
Oliver lives with his wife in a small house on a volcano and spends his evenings perfecting the sound of his speakers made from a tree grown next door. Life is too short for bad sound.Get in touch via

What’s up with the bicycle helmet?
Thomas is a very responsible man, putting safety of product designs first. This may sound a bit dull, but don’t be mistaken; Thomas has the most creative brain on the team. When he is cycling 40 km/h, we’re very happy he’s wearing the helmet. We just can’t afford to lose creative intelligence.Get in touch via

Rutger StapelkampProduct Design Engineer
Rutger got his Product Development master’s degree in 2014 in the country known for chocolate and beer. After a busy year on the road, he finally chilled down to push our biogas milk chillers forward. He’s here for his hands-on problem solving now that the coolers move from laboratories to factories. Next to that he’s becoming a programming nerd to make sure our remote monitoring devices send us the data we want!
What’s up with the tools?
Rutger believes design engineers should leave their drawings and CAD models as soon as possible. By making it we learn about its challenges and possibilities. This way we can deliver better functionality and be sure products can actually be made.Get in touch via

What’s up with the plant?
Someone’s sitting in the shade today because someone planted a tree a long time ago. Anuja believes the way to create an impact is by planting a seed that will grow itself into a beautiful plant. How to you grow this seed into a beautiful plant? By using manure made from biogas of course.Get in touch via
