CEDaCI – Circular Economy for the Data Center Industry

Featured image

The Data Centre Industry has grown rapidly and generates a large volume of e-waste / WEEE. The current infrastructure for dealing with this waste is underdeveloped and consequently, there is a real and urgent need to address this now. CEDaCI will build a Circular Economy for the Data Centre Industry by bringing together stakeholders from all equipment life cycle stages to turn this waste into a useful resource and support the ongoing rapid growth of the DCI.

The Kaskantine will implement together with the neighboorhood its design for closing local resource loops: a kitchen with closed water cycle, preventing local food waste, introduce neighbourhood composting, and organise repair cafe's, sport and musique workshops, etc. Data will be gathered to monitor the resource cycling and methods will be tested to make it more socially and culturally inclusive.

User-created nature-based solutions in an urban environment;

The case of the KasKantine (Greenhouse Cantina), Amsterdam

Historically landscape architecture and infrastructural planning have assigned physical separated functions to landscape in order to upscale and manage resource flows cost efficiently. Rather than monosectoral and large scale linear production systems we can now see a shift to decentralized and locally integrated solutions to close resource loops. In these solutions also citizens can play a more (pro)active role. After being more prominent in rural areas, landscape architecture is now also more active as a lead design principle in urban neighbourhoods. Local integrated solutions for resource cycling efficiency give rise to multiple value production rather than to an increase of local financial income. Either way it increases citizen driven (semi)professional activities in resource management in urban neighbourhoods, as well in its creation and in management.

We see enormous potential in this approach: it can reconnect citizens to nature, it can facilitate in changing lifestyles AND produce the right technology to face our climate and resource crisis. But before it can become mainstream, we see the following challenges and questions, mainly to do with creating sufficient local political support and accessibility to these technological and economic opportunities.

  • How can actors on local level on one side and central sectoral level at the other side co-create and redesign effectively the landscape, necessary to close resource loops locally with sufficient democratic legitimacy?
  • How could citizen-driven services in resource management be held accountable to a broader public and the public sector?
  • How can these nature-based solutions be culturally and socially inclusive?
  • How can socio-economically marginal(ized|) groups profit from this increased multiple-values production?

We can try to answer those questions for one specific case to see how it could work out in practice. The Kaskantine is a not-for-profit volunteer driven garden- restaurant - food coop which has as its main objective to show that more autonomous, off the grid nature based solutions for climate adaptive working and living in urban areas are possible and can be at the same time a new lifestyle. It is a small village of refurbished shipping containers, recycled greenhouses and (roof top)gardens. The Kaskantine is currently being built on its fourth location and is negotiating a 7 years ground lease with the municipality of Amsterdam.

The Kaskantine managed to grow from only one container and a one-man company, 5 years ago, to a cooperative with over 30 volunteers with 13 containers. A second village is being planned of 7 containers in the east of Amsterdam. This has been realised without any external capital investment or subsidies. The strategy has always been: find a solution with the least possible financial costs and turn untapped local resources into value.

In doing so the Kaskantine discovered that although real estate prices in Amsterdam skyrocket, there is still a lot of underutilised land and water, that is without use for people and for nature. Lots of plots are “waiting” to be developed, or are underdeveloped: for one function while there could be double or triple functionalities. We could call this “real estate waste”. The Kaskantine could use land for free because there was no direct market value of that land. And the same counts for other important resources: (rain)water, (solar)energy, food (waste and own production), labour (volunteers) and (natural and waste) materials. The Kaskantine is able to operate with zero fixed costs and therefore able to survive.

Furthermore, with its installations it is trying to integrate all received good and services in local loops. Maximum in, minimum out. This is optimized by integrating different resource loops in one management system.

An abundance of one flow of resources can be absorbed by other resource cycles: Peak solar energy can be used in extra ventilation, aeration and irrigation. Sudden food surpluses are redistributed for free and create network solidarity. The Kaskantine is also able to use resources in all phases of their life cycle, like wood: from construction to fire wood. Or being able by using rest heat in storing it in mass or other spaces, or filtering waste water for irrigation. We call this adaptive capacity: the capacity to buffer abundance and use it later or in an alternative way.

Finally, an alternative lifestyle is embraced, one that is appreciating the value of abundance of local resources, rather than the value of market choice.

We could argue that the Kaskantine is thriving in an alternative economy, that can exist thanks to and despite of the mainstream economy that they are trying to transform. We call this abundance or give economy, in contrast with economy based on consumption and the organisation of scarcity.

Abundance economy as being a sum of relatively autonomous integrated projects in mainstream economy.

Because of its ability to expand autonomously within mainstream economy, and because its abundance economy is not a zero-sum game as long as local resources and waste are underutilised, the Kaskantine is very open for participation. There is no economic argument against including more neighborhood activities, on the contrary. More participation seems therefore to depend more on the capability of cultural inclusiveness: if people feel comfortable within the network of the Kaskantine, or if people feel comfortable to start a sort of “kaskantine” on their own.

First, the opportunity to integrate has been ”built in” into the design of the Kaskantine by a step-in approach. From experience as a guest (exchange, tasting, get inspired, etc) to participation in the design, creation and operation of the Kaskantine and Kaskantine related projects.

Secondly, the Kaskantine is also active in the neighbourhood centre and within a network of community organisations, with a step-out approach. In this case the Kaskantine offers through free workshops a learning curve to adopt small scale installations, like vertical gardens and worm composting, and participate in food saving and storage at home in order to take a step back from mainstream economy into the abundance economy.

An important ambition of the Kaskantine is to negotiate with the municipality a land lease contract in which the landuser takes responsibility for its development and environmental control of the land. This cheaper land rent will hopefully give other “kaskantines” the opportunity to arise.

The Kaskantine has free energy to spend on helping other groups in joining this movement because it can operate autonomously and with low fixed costs. This creates hopeful opportunities for inclusiveness of the proposed solutions. Whether this is done in some kind of co-creation with more central institutions depends more on their own capability to work with local small scale initiatives and on their willingness to change or compensate the negative effects of their lineair production models and on their willingness and capability to change sectoral into integrated policies.

EyeBeacons: Wayfinding in Public Spaces

Featured image

Navigating from A to B is an essential part of our daily lives.
Unknown routes, busy places and unexpected obstacles are a big challenge for everyone, regardless of what your eyesight is. For people with a visual impairment, this process is primarily a task because they have limited use of spatial orientation and directions in the environment. The EyeBeacons project investigated how new technologies can support people with a visual impairment when navigating through the city.

YIMBY Yes-In-My-Back-Yard Amsterdam!

Featured image

The grassroots movement YIMBY Yes-In-My-Back-Yard! stimulates local food growing in the city. The so called YIMBY food growing containers are the first food growing experience for citizen. Together with green lessons citizen will grow in local food growing in the city. At the national neighbour day a yearly green event is organized to exchange green ideas and good food.

Arnhem - Het Arnhemse burgerinitiatief YIMBY, Yes-In-My-Back-Yard Arnhem! is genomineerd voor de duurzame Top 100 van het dagblad Trouw. De elfde editie van de duurzame Top 100 in 2019 is een lijst van onderop, van burgers die het heft in eigen handen nemen en zelf een duurzaam initiatief opzetten.

In 2013 hebben burgers vanuit het buurthuis 't Huukske in Arnhem-West het initiatief genomen om mobiele moestuinbakken op te zetten in de wijk. Het initiatief krijgt al snel de naam YIMBY Arnhem! De afkorting YIMBY staat voor Yes-In-My-Back-Yard en betekent dat burgers positief staan om eigen initiatieven in de achtertuin te starten. Bij YIMBY Arnhem! staan moestuinbakken, groen en ontmoeten centraal.

Voor de burgers in de wijk zijn de YIMBY moestuinbakken vaak de eerste kennismaking om zelf groenten en kruiden in de stad te verbouwen. De ervaring is dat de eigenaars van YIMBY moestuinbakken als vervolgstap kiezen voor het telen van groente in een grotere voedseltuin in de stad. Om het telen van voedstel te ondersteunen wordt ieder voorjaar in de wijk de cursus "Biologisch Tuinieren in de Stad" gegeven.

De YIMBY moestuinbakken worden al zeven jaar gemaakt door deelnemers en vrijwilligers van de zorgboerderij Hoeve Klein Mariëndaal in Arnhem-West. In totaal hebben de timmermannen van de Hoeve Klein Mariëndal al meer dan 100 YIMBY moestuinbakken geleverd. Voor de zevende keer wordt op de Hoeve Klein Mariëndaal het YIMBY Oogstfeest gehouden op burendag. Het YIMBY Oogstfeest wordt georganiseerd door vrijwilligers en nodigt deelnemers van de zorgboerderij en eigenaars van de YIMBY moestuinbakken uit voor een zelfgemaakte maaltijd. Deze maaltijd wordt gesponsord door de middenstand in de wijk Arnhem-West.

Op 10 oktober 2019 wordt de lijst van de duurzame Top 100 van het dagblad Trouw gepresenteerd. In zeven jaar zijn veel resultaten met groen en ontmoeten in de stad Arnhem bereikt. Gezien het langdurige succes van de YIMBY moestuinbakken is de kans groot dat YIMBY Arnhem! in deze lijst zal voorkomen.

RESILIO - Amsterdam Blue Green Roofs

Featured image

The EU-UIA funded the programme RESILIO, a project that aims to realize 10.000 square meters of blue-green roofs in four city districts in Amsterdam. The consortium of both public and private partners aims to build an interconnected network of smart roofs, in which sensors and state-of-the-art equipment enable micro-water management on rooftops. This contributes to urban climate adaption and resilience, and can potentially evolve into a scalable solution for water management on rooftops.

This project is co-financed by the European Regional Development Fund through the Urban Innovative Actions Initiative.

ATELIER - Positive Energy Districts (EU)

Featured image

ATELIER is an AmsTErdam and BiLbao cItizen drivEn smaRt cities project funded by the European Commission under the H2020-LC-SC3-2018-2019-2020 Smart Cities and Communities call.
Coordinated by the City of Amsterdam, the project combines the expertise and the commitment of 30 partners from 11 countries.

ATELIER focuses on developing citizen-driven Positive Energy Districts (PEDs) in the two Lighthouse Cities Amsterdam (Netherlands) and Bilbao (Spain). Their successful implementations will then be replicated and tested for feasibility in the six Fellow Cities Bratislava (Slovak Republic), Budapest (Hungary), Copenhagen (Denmark), Krakow (Poland), Matosinhos (Portugal), and Riga (Latvia).

Via dedicated PED Innovation Ateliers, ATELIER will strengthen the local innovation ecosystem and thus remove legal, financial or social barriers to the implementation of smart solutions. The PED Innovation Ateliers will be self-sustaining, continuing for a long time after the project has ended. They will thus become engines for the upscaling and replication of solutions within the ATELIER cities and beyond.

To achieve successful implementations of energy saving measures, ATELIER puts citizens at the centre of all its activities: residents (
To really pave the way for more ‘positive’ cities in Europe, each of the eight ATELIER cities will develop a City Vision 2050 that constitutes the roadmap for upscaling solutions in the long term. The main objective of this is to guarantee a seamless city transformation from planning to implementation and further upscaling and replication.

Amsterdam Biochar Initiative

Featured image

Biochar is a soil amendment made typically from bio-mass through a process called pyrolysis with low-oxygen. By using a low-cost, easy-to-make biochar stove, communities can arrange to turn common waste products into biochar.
The vision behind this project is for healthy and resilient communities. This means that I prefer methods that promote local, DIY and community approach, so that it can quickly scale and adapt to different towns/cities.

Most importantly, carbon being the element behind Life has tremendous versatility. It can be used to filter water and then used as a soil amendment. Or it can be mixed to make better concrete composites for roads (asphalt) and concrete. It can improve manufacturing by making carbon fiber alloys.
Last but not least, it is done through a circular model of using waste such as wood sticks, bio-mass, paper, saw dust mills, anything with carbon, even plastics. The output heat can be captured for heating buildings and cooking stoves. The opportunities are endless.
Sizes of stove vary in function of available supply/demand dynamics. For more information, check the or Ithaka International.
Thank you.

PS: Stockholm, Sweden has achieved this recently. If the Swedes can do it, we can learn from them and improve together!

Program Smart Mobility Amsterdam 2019 - 2025

Featured image

An accessible, liveable and less polluted city: this is what we’d like to achieve for residents, visitors and businesses in Amsterdam today and for future generations. Smarter and cleaner mobility can help us realise these aims. As a city, we want to offer Amsterdammers, commuters and visitors alternatives to the present forms of mobility, providing a door-to-door solution and contributing to our aims. This includes shared electric transport, from cars to bikes, in ‘Neighbourhood eHubs’ (eBuurthubs) established in cooperation with local residents. That way, we can use clean modes of transport and create more space in the city by sharing. We can then use this extra space to improve liveability.
More info and link to the program via

Check the report:


To achieve the ambitions, we will start working with two program lines:

1. Data and digitization
This program line helps the municipal organization digital tools and skills to ensure sufficient control in the future be able to rely on mobility in the city and around
improve quality in public spaces. We are working towards a mobility center of the
future. For this we will use the take the following steps:
• A shared basis: building a strong one data position
• A level playing field: frameworks
• Learning by doing: from traffic management to mobility management
• Ready for the future: aware of the consequences of digitization of mobility

2. Innovative mobility solutions

In this program we work together on concrete smart and clean alternatives to transport, so that Amsterdammers and visitors to the city are less dependent on their own car. We do this by setting up projects in certain urban areas and for specific target groups. We also focus on smart city logistics and we explore the possibilities of transport by water and air. Special attention is given to vulnerable groups and Amsterdam residents with a small grant. We improve the range of new affordable mobility concepts and increase demand, we grow into smart mobility city number 1 with a better and accessible mobility system for everyone. For this we will include the following in this program:

• Smart organization of mobility in the city: travelers are working on alternatives to possessing cars and initiating behavioral change.
• Smart fitting and efficient deployment of new mobility solutions: creating space for new concepts in the city and scaling up
• Anticipate on technological innovations: insights into new opportunities and collaborations. The report contains an overview of the various projects started in the previous program that are still running and newly started activities.

Civic Space

Featured image

Civic Space helps local authorities make more informed decisions. We constantly collect and analyze the comments, ideas and suggestions of each citizen of the platform. Our software for civic participation enables local governments to take advantage of the collective minds of citizens and better understand the needs of their citizens.
We believe that with the Civic Space platform, we will give the public the opportunity to influence socially-minded decisions, to engage in joint policy-making with the municipal authorities.

Civic Space - is online citizen participation platform for adding citizens to city governance

The platform facilitates a bilateral dialogue between the municipal government of the city and its inhabitants. Citizens publish ideas, take part in competitions, public consultations, debates, implement joint projects in a convenient and accessible form.

The municipal authorities of the city consult with their citizens by conducting online debates, public consultations, polls or holding a contest of creative solutions for the existing problem. The platform helps cities turn to the collective intelligence of citizens. Understand, hear citizens. Become more sensitive to the needs of the public.

Civic Space, it helps local governments become more citizen-oriented.

Civic Space, it helps citizens participate in the process of managing a city, making decisions, and developing local policies.

Thanks to our user-friendly cloud solution, we significantly simplify the process of communication, and the attraction and cooperation of the most vulnerable segments of the population. Like any similar Internet solution, the platform allows you to join the process of participation of all segments of the population despite religion, gender, political preferences, nationality, skin color and participate in the discussion on equal terms with all other participants.

The platform allows everyone to express their opinion, suggestion, comment on equal terms, and so receive an answer, comment, recommendations from other participants of the platform.

Also, the cloud service platform, due to the absence of the need for administration, moderation, support and maintenance of the platform, allows residents of small towns to join the process of participation. The availability of Internet access is all that is necessary for city residents in order to join the platform.

We make attracting citizens to participate affordable, easy, understandable and convenient!

Metropoolregio Amsterdam Maquette

Featured image

Werkmaquette Metropool Regio Amsterdam 2019 1:20.000
Deze maquette helpt, bij overleg met verschillende partijen, om standpunten duidelijk te maken. De maquette is nodig om problematiek van een dichtbevolkte regio in beeld te brengen. Daarbij kan het gaan over verkeersknooppunten, over bouwlocaties, maar ook over geluidsoverlast of over natuurbeheer. De vormgeving van de maquette is door mij ontworpen en gemaakt voor een grote en toch ook diverse gebruikersgroep van beleidsmakers en belanghebbenden in opdracht van de Gemeente Amsterdam

Interactieve Planbespreking
De maquette is zo groot als een tapijt, met een formaat van 440cm x 312cm. Het bestaat uit meerdere panelen. Tijdens besprekingen kan er op de maquette worden gelopen. Een blauw Poly Urethaan matte lak vormt de onderlaag. Daarop is, eveneens met een UV bestendige lak, de cartografie op de panelen geprint. De blauwe zeepkisten bevatten legenda items die op de kaart kunnen worden gelegd. Alle legenda items kunnen weer weg worden gehaald of verplaatst. (De opstelling op deze foto is een schetsmatige weergave en bevatten geen inhoudelijk plan.)

Legenda; kleur, vorm en materiaal
Voor het maken van de legenda heb ik onderzoek gedaan naar de te gebruiken iconografie; in welk materiaal en in welke kleur de artefacten verbeeld moeten worden. Dit kleurgebruik, het icoon, het materiaal (en zelfs de mate van transparantie) zijn alles bepalend. Dankzij dit systeem is de legenda flexibel en zij kan zelfs makkelijk worden uitgebreid. Deze legenda-taal zorgt voor een begrijpelijk geheel en het helpt mensen om er snel mee aan de slag te kunnen gaan. Met het kleurschema kunnen zelfs abstracte begrippen worden verbeeld, zoals geluidoverlast (en hoeveel dan) of bijvoorbeeld aantallen arbeidsplaatsen. De maak methode van de artefacten op de maquette varieert van laseren, 3d printen en rijgen, tot plakken en knippen.

WarmBouwen-pilot in Amsterdam

Featured image

WarmBouwen is een techniek die gebruik maakt van restwarmte bij het isoleren van woningen. De techniek zorgt ervoor dat de buitenschil van de woning op temperatuur blijft waardoor er vrijwel niet verwarmd of gekoeld hoeft te worden. De restwarmte wordt door dunne buisjes in combinatie met (duurzaam) isolatiemateriaal op de wand geplaatst. De techniek is makkelijk te plaatsen, het isolatiemateriaal is slechts enkele centimeters dik en daardoor makkelijk toe te passen in de bestaande woningen in Amsterdam (zie de infographic voor een duidelijke toelichting).

Warmbouwen is a technique that makes uses of residual heat in the insulation of houses. The technique ensures that the outer shell of the house stays on temperature with the result that there is barely any heating or cooling needed. The residual heat goes through small tubes and is combined with an (sustainable) insulation material, this combination is then placed on the wall. The technique is easy to install, the insulation material combined with the tubes is just a few centimeters thick and so easy to apply in existing houses in Amsterdam.
