The Brussels-based start-up Sirona Technologies adopts a revolutionary approach towards CO₂ emissions

11/08/2025

Alongside other innovative methods of reducing CO₂ emissions, removing CO₂ directly from the atmosphere represents a major step forward in our efforts to achieve sustainability for our planet. Sirona Technologies from Molenbeek-Saint-Jean in Brussels has already gained knowledge and expertise in that particular field.

According to the company's founders, Direct Air Capture (DAC) is the dream solution that everything will depend on. As they themselves point out, filtering out the necessary 5 to 10 billion tons of CO₂ from the air annually worldwide is ultimately only possible using a revolutionary method like the one that their company provides. Planting a new forest the size of Asia wouldn't even be sufficient to achieve that, in their view. So on an old industrial site, they started building containers housing a set of machinery resembling giant vacuum cleaners with pore filters in the fans that suck in the ambient air and extract CO₂. The CO₂ extracted is captured and then released using steam, to be stored deep underground, where it can mineralise into rock.

Once the first commercial container becomes a reality in September, Sirona Technologies intends to allocate additional capital and expand its workforce to rapidly scale up smart and modular installations of that type at strategically selected locations. One such location is Kenya, which has renewable energy in abundance and where direct air capture is therefore affordable. Producing certified carbon credits will enable companies and individuals worldwide to offset their emissions.

This new initiative will not only provide a boost for our climate, but will create employment as well.
