It’s a great societal challenge to keep the air quality in and around cities manageable. And it’s not just the traffic to blame. Burning coal and wood for heating and cooking, agriculture, as well as industry all play a role in causing bad urban air quality.

In places where people are learning, playing or spending their free time, it is important to be surrounded by clean air. Our solutions can be integrated in exsisting infrastructure and applied to create clean air zones. Good for the residents. But especially for the children.

Co-creating clean air

Together with Suez and Fermentalg we developed a unique solution for playgrounds and courtyards, which combines multiple air purifying technologies with the carbon capturing potential of microalgae. By capturing fine particles and nitrogen dioxide  a clean air bubble is created. The micro-algae absorb the captured pollution and creates oxygen and forms a residual biomass, which can then be used for green energy production.

Our air purification technology can be integrated in various ways for courtyards and playgrounds

  • Smog Free Tower

    A powerful statement that raises awareness and provides a solution for better outdoor air quality. The heart of the Smog Free Tower is formed by three of our systems.

  • Suez

    An innovative solution for schoolyards to improve playground air, allowing children to play healthily. Besides, it also to helps school children be more aware of environmental concerns.

  • American Embassy School

    By purifying the air in the courtyard of a high school, students and staff are exposed to significantly lower particulate matter concentrations during lessons, breaks, and while changing classrooms.
