I am a designer.

Can I help in any way?

The Birla Institute of Technology and Science, our partner in the G2RT field tests, asked us if we could develop a simple vacuum system for India. BITS professor Srikanth Mutnuri is conducting research there on plant-based wastewater treatment, as well as on biogas production. Our discussions msubsequently led to the idea of combining both technologies – as reflected in the project name.

The ZUV (Zero Emission Utility Vehicle) is a circular vehicle concept for ,electrically powered cargo bikes that can be 3D printed from recycled, PP plastic in decentralized fab labs. Rotterdam-based design and production studio The New Raw took charge of the 3D printing.

G2RT – Generation 2 Reinvented Toilet brings together leading sanitation technologies from around the world to accelerate the next generation of safe, off-grid toilets. The project unites more than 70 engineers, scientists, and industrial designers from universities and industry to develop an affordable, reliable sanitation solution with the potential to improve global access to safe sanitation. As design lead, EOOS Next shaped the user experience, toilet design, and vacuum system, helping transform cutting-edge research into a solution ready for real-world implementation.

The Open Design Mold enables the local production of urine-diverting toilet inserts using simple materials and open-source construction plans. Designed for remote rural areas, it empowers local craftspeople to build affordable sanitation solutions with locally available concrete.

The multimedia installation explored circular principles in agriculture and highlighted the potential of urine separation to recover valuable nutrients. Curated by Marlies Wirth (MAK Vienna) as the official Austrian contribution to the Triennale, the project received the Black Bee Award in Silver. Digital material flows were visualized by Process Studio.

Save! is the first commercially available toilet to use Urine Trap technology, making circular sanitation accessible without changing everyday routines. Developed with the support of the Gates Foundation and Swiss manufacturer Laufen, it prepared the technology for mass production and introduced it first in the Global North, positioning urine separation as an innovation for everyone.

Supported by the Gates Foundation, the Urine Trap uses the “teapot effect” to separate urine from flush water through surface tension alone. Slow-flowing urine is diverted, while fast-flowing flush water passes over the edge—without valves, chemicals, or moving parts.

The Urinator is an open-source research tool that simulates realistic urine flow using 3D printing. Developed to accelerate the design of urine-separating toilets, it enabled rapid testing without relying on volunteers. The findings from this research were published with academic partners in the scientific study How Men and Women Pee.

In 2016, the projects realized for refugees in Vienna by The Next ENTERprise, Caramel and EOOS were presented in the Austrian Pavilion in Venice designed by Josef Hoffmann – accompanied by a newspaper with detailed descriptions of the individual interventions as well as poster-sized photographs by Paul Kranzler that captured the atmosphere in the refugee accommodations. The presentation was Austria’s contribution to the Biennale exhibition, curated by Alejandro Aravena under the motto “Reporting from the Front.”

A total of 18 different furniture designs came into being for the refugee accommodation. In the wood workshop we initiated, almost a thousand furniture items were made based on detailed building instructions – each time one was finished, a colored dot was stuck on a poster. We turned the Social Furniture building instructions into a handbook, which is also available as open source material for like-minded initiatives.

Social Furniture explored how design can transform emergency accommodation into a place of dignity, participation, and community. Developed for the Austrian Pavilion at the 2016 Venice Architecture Biennale and tested at Vienna’s Haus Erdberg refugee center, the project introduced practical, human-centered interventions—from free Wi-Fi and adaptable furniture to communal spaces—that improved everyday life.

EOOS ’s first project within the Gates Foundation’s Reinvent the Toilet Challenge. Developed with Eawag, it pioneered a decentralized sanitation system that separates urine, feces, and water to recover resources while providing safe, off-grid sanitation. Extensive field tests in Uganda, Kenya, and South Africa shaped the design and led to key innovations—including the Urine Trap—that laid the foundation for the next generation of circular sanitation technologies.
