From space-faring innovation to enhancing life on Earth, the GreenLung® project is undoubtedly an authentic example of technology transfer from space to other industries. Developed by Redwire Space nv, a Belgium-based prominent company in space systems, GreenLung® is derived from technologies developed for life support systems on the International Space Station and for long-term human space exploration. Ensuring clean air and resource efficiency is a priority in extreme environments such as space habitats; the fact that it happens through a biological process with useful byproducts only adds to the appeal of this approach. Its application in sustainable architecture on Earth was almost inevitable.

Recognizing the pressing need for improved indoor air quality on our own planet, Redwire successfully adapted this advanced photobioreactor technology for terrestrial use. GreenLung® now offers a comprehensive solution for purifying indoor air by removing CO2, VOCs (volatile organic compounds), particulate matter, and airborne pathogens, while simultaneously producing oxygen. Its modular and aesthetically pleasing design makes it suitable for diverse environments, from corporate offices and public buildings to hospitality venues and cultural institutions.

The project’s success is further amplified by its commitment to sustainability, with the system utilizing natural processes, reusing nutrients, and producing bio-based materials from harvested biomass, contributing to a circular economy. The collaborative approach, involving a consortium of stakeholders, and a robust business model that incorporates both direct sales and a Product-as-a-Service (PaaS) option, underscore the project’s strategic vision and potential for widespread adoption.

Besides the benefits of the air purification system, GreenLung® is also an educational tool, fostering ecological awareness and demonstrating how nature-based systems can balance our environment.

This remarkable journey from space technology to a tangible solution for everyday indoor air quality challenges exemplifies a successful and impactful transfer of knowledge, promising healthier and more sustainable environments for all.
