Projects
Oceanhamnen | Helsingborg
Oceanhamnen is an innovative, water-friendly district in Helsingborg, Sweden. The neighborhood has been built on a former harbor area and is part of the “H+” project, which aims to improve and strengthen the connections between existing districts and the city center.
This innovative district will consist of 343 households, including 3 office buildings and a community building, the “RECO-lab”: an open and accessible meeting place for companies, researchers, and public stakeholders, focused on research, development, education, and communication in the field of sustainability, including urban planning and utilities.
Greywater is treated locally to drinking water quality, with the excess water discharged into the sea. Blackwater (toilet water) is collected separately through vacuum toilets and digested for the recovery of nutrients in the form of struvite and ammonium sulfate.
Food waste, after being ground in a household food disposer, is collected separately through an LPS system and processed in a separate UASB reactor. After this, it undergoes the same steps for nutrient extraction. The biogas from both digesters is supplied to the central gas grid.
Schoonschip | amsterdam
Located in the north of Amsterdam, Schoonschip is a residential neighborhood made up of houseboats, initiated by the residents themselves. These 30 houseboats, home to 46 households, together form “the most sustainable floating neighborhood in Europe” and include a communal space to strengthen social cohesion and shared electric mobility.
Sustainable elements such as aquathermal heating using water from the canal, heat recovery from showers, and separated greywater and blackwater streams with biogas recovery highlight the sustainable character of this project. In addition, the neighborhood is committed to facilitating further innovations and experiments, such as bird protection through floating gardens and the expansion of shared mobility solutions for the surrounding neighborhoods.
Jenfelder au | Hamburg
Located on the grounds of the former Lettow-Vorbeck military barracks in the Hamburg-Jenfeld district, the Jenfelder Au project focuses on the construction of 835 households that utilize the Hamburg Water Cycle ©: a closed-loop system for wastewater management.
The system includes infiltration basins for rainwater, a setup for testing two methods of greywater collection and treatment, and a separate vacuum system for the collection of blackwater with nutrient and biogas recovery. This project is part of the IBA (International Building Exhibition) Hamburg.
de nieuwe dokken | gent
Located on a former industrial site in the port of Ghent, De Nieuwe Dokken is building homes for 244 households, including 3 office buildings, 2 community buildings, and 20 shops.
The sustainable character of this urban development is reflected, among other things, in the designation of the area as a car-free zone, heat supply through residual heat from surrounding active industries, and source separation of greywater and blackwater from vacuum toilets and ground food waste.
The biogas produced is then used as an energy source, and struvite is applied as fertilizer. The recovered water is treated locally and serves as process water for the surrounding industry.
citypilot | amsterdam
Within walking distance of Schoonschip, in Buiksloterham, lies this pilot area for innovative urban development in the north of Amsterdam. Here you will find Cityplot: a project that provides space for 250 households, including one hotel and several work units, with a clear focus on sustainability.
Resources and energy are recovered from wastewater, which is separated at the source into blackwater and greywater and further processed in a UASB reactor. This reactor is powered by the biogas generated during this process.
For residents’ transportation, space has been reserved for shared mobility facilities.
superlocal | kerkrade
This ambitious project, part of IBA Parkstad, is located in the city of Kerkrade, in the far south of the Netherlands. Its aim is to create a cohesive and sustainable neighborhood for 129 households, with a focus on community cohesion through shared buildings and the use of construction materials reclaimed from the demolition of previously existing buildings on the site.

The project aims to apply a wide range of sustainable technologies both indoors and outdoors, including vacuum toilets, shared food waste disposers, recirculating showers, and rainwater harvesting for drinking water use (90%), with overflow into a buffer and infiltration pond. Greywater is treated through an aerated helophyte filter for household reuse, while blackwater is treated in a UASB reactor with nutrient recovery for landscaping and biogas production.
