Claes Kollberg
Chief Technology Officer, CemVision AB
Claes joins Breakthrough Energy’s Innovator Fellows program from CemVision AB, based in Nybro,Sweden. Claes is an engineer and entrepreneur with more than 18 years of experience renovating, building, and managing cement production plants in Africa and Europe. As the Chief Technology Officer, Claes is responsible for developing the production process and optimizing the raw materials, energy production, and heat transfer components of CemVision’s new cement production process.
CemVision is reinventing cement by replacing fossil limestone with waste materials and switching fuels such as plastic and coal for green thermal energy. CemVision creates non-traditional cement that has not only superior product properties compared to traditional Portland cement but also a lower carbon footprint due to reduced need for limestone. In addition to reducing CO2emissions, CemVision’s novel cement technology makes concrete construction faster and more resource efficient. Through the Fellows program, Claes and Paul will develop the technology and intellectual property in order to scale their solution for meaningful production, aiming at > 90% reduction of CO2emissions compared to traditional cement.
Claes studied Energy Technology at University of Cape Town in South Africa through an exchange program at INSA de Lyon, France and earned a Master of Science in Mechanical Engineering from the Royal Institute of Technology in Stockholm. Claes has been lecturer in Strategic Sustainable Development and Corporate Social Responsibility at Uppsala University in Sweden.
