Waternet will implement a neighbourhood bio refinery, a small scale treatment unit in which raw materials and energy can be recovered from black waste water.
City-zen was an international consortium, a program stimulating learning-by-doing in Grenoble and Amsterdam between March 2014 and November 2019. The results can be found in a booklet or in detailed reports. http://www.cityzen-smartcity.eu/home/reporting/deliverables/
City-zen partner Waternet, public water company for the Amsterdam region, is involved in the development of ‘Circular Buiksloterham’, a new residential area in the north of Amsterdam. For this purpose the water company is developing a so-called ‘New Sanitation’ system: a system in which waste water streams are separated at source (in households) and processed locally.
Waternet will implement a neighbourhood bio refinery, a small scale treatment unit in which raw materials (nutrients such as phosphate) and energy (biogas) can be recovered from black waste water (waste water coming from toilets and possibly food grinders). The black water is captured through a vacuum sewer system.
Currently the grey waste water stream (coming from showers, washing machines and the kitchen) will not be collected and treated locally yet but the Buiksloterham system has the potential to do so in a later stage. For now, it will still be collected via a traditional sewer system. A local grey water treatment unit would facilitate the recycling of water and heat.
Waste water carries raw materials (like plant nutrients) and energy (heat and biogas). Most of these are lost in our current waste water systems. A good example is phosphate: it is essential to feeding the world, but its excessive use as a fertilizer has led to widespread pollution and eutrophication. A huge amount of phosphate is flushed out into the surface water by waste water treatment plants around the world. At the same time many of the world’s remaining phosphate reserves are starting to be depleted.
To recover minerals like phosphate we should change the way we handle our waste water, and treat it as a valuable resource. In practical terms this means that we should keep the different types of waste water separated to be able to recover energy and minerals efficiently.

Get up at your feet and join for a summer excursion in Amsterdam-Noord! Although we see more and more solar panels in our streets, as a resident you see very little of the energy transition in the neighbourhood. in Amsterdam, there is already a neighbourhood where the future has started: Buiksloterham in Amsterdam North. Buildings in this area are natural gas-free and almost all of them obtain their energy in a different way.
Be aware that the main language is Dutch!
To make this visible, little glimpses have been placed in the public space. The art objects give virtual glimpses into the devices and installations behind walls and in basements. On the pavement, a 3D painting shows where the district heating network runs, and a viewing tube shows you how full the neighbourhood battery is underground. If you walk past it often enough, you will start to see connections: the weather was really nice today, so the battery is completely full!
During this Waag Open, we'll take a walk alongside different glimpses. All facets of the energy tranisty are covered: we show how deep the boreholes of the thermal storage are and where exactly the heat from the heat network comes from. There is also a focus on solar panels, batteries and heat pumps - of all shapes and sizes! Take a walk with us on Thursday 1 August and you're bound to learn something new about the energy transition!

Het valt niet meteen op, maar in Amsterdam Noord is de toekomst al begonnen. De wijk Buiksloterham loopt internationaal voorop in de energietransitie. Gebouwen in de buurt zijn aardgasvrij, en verkrijgen hun energie bijna allemaal op een andere manier. Als voorbijganger of bewoner zie je daar nu weinig van.
Het project ‘Inkijkjes in de Energietransitie’ brengt daar verandering in. Met schilderingen en kunstobjecten op straat geven we virtuele inkijkjes in de apparaten en installaties achter de muren en in kelders. In kijkbuizen met animaties wordt de werking van een warmte-koude-opslag, of het stadswarmtenet, je in een minuut uitgelegd.
De nieuwe technieken mogen gezien worden! Door een wandeling langs de verschillende inkijkjes kom je meer te weten over de verschillende facetten van de energietransitie.
Zo maken we de energietransitie tastbaar, en de discussie erover concreter.
Kom je naar de opening? Op donderdag 13 juni worden de Inkijkjes in de Energietransitie officieel geopend. We presenteren de installaties aan alle betrokkenen: van expert tot bewoner, en aan de buren.
Wanneer: Donderdag 13 juni, 16:00 - 19:00 uur
Waar: Asterdwarsweg 5, Amsterdam Noord
Meld je aan: door te mailen naar floortje [at] waag [punt] org
Het concept ‘Inkijkjes’ komt voort uit de artistieke oproep van Waag Futurelab en een intensief buurtonderzoek (bezoeken, interviews, workshops met buurtbewoners) samen met de geselecteerde ontwerper Tessa Steenkamp en haar design studio Bits of Space.
