In the 19th episode of the Better cities - the contribution of digital technology-series, I address the question of how digital technology can help in the long road to a circular society.
The contribution of digital technology becomes most visible when viewed in conjunction with other policy instruments and actions. That is why in this episode Amsterdam is in the spotlight; this city has been pursuing a consistent circular policy from 2015 onwards.
Why is a circular economy necessary?
European countries together need an average of 2.9 copies of planet Earth to meet the needs for raw materials. But even one Earth has finite resources, and it is therefore obvious that more and more countries aim to be circular by 2050. The circular processing ladder contains a range of options with the lowest step recovery of energy from materials unsuitable for re-use and furthermore recycling, repurposing, remanufacturing, renovation, repair, reuse, reduction, reconsideration to rejection.
A circular economy is an economic and industrial system that eliminates waste and takes the reusability of products and raw materials and the regenerative capacity of natural resources as a starting point, minimizes value destruction in the total system and pursues value creation in every link of the system. In this context, the term cradle-to-cradle design is often referred to. This is done in terms of material flows and the preservation of values, so that in the long term there is no longer any need for an influx of virgin materials. Maersk has developed a cradle-to-cradle passport, a first for the shipping industry, consisting of a database of all ship components, including all the steel, for recycling, reuse and remanufacturing of new ships or their parts.
The Digital Sustainability-memorandum is considering digitization as an enabler on the way to a circular economy. A fourfold distinction is made in this regard: (1) the coordination of supply and demand of materials, (2) facilitating maintenance and repairs, (3) improving the production process, and (4) supporting partners in chain cooperation. Examples of all these options are discussed below.
Amsterdam and the realization of circular principles
Amsterdam's ambition is to use 50% less virgin raw materials by 2030 compared to the current situation. This goal is also very important for achieving its climate targets: 63% of the CO2 emissions for which the city is responsible come from products and materials that are produced abroad. The municipal government can only partly influence this steam. That is why the policy focuses on three areas where the city has most influence, namely food and organic residual flows, consumption and the built environment.
Amsterdam published its first policy plan Amsterdam Circular: Vision and roadmap for the city and regionin 2015. The emphasis was on organic waste and the built environment. It included 75 action points and its approach was positively evaluated in 2018 and a new report was published. It was decided to continue with the same emphasis with the addition of food and consumption. The addition of consumption was obvious, because Amsterdam had been making a strong case for the sharing economy for some time.
Shortly after the publication of the new report, Kate Raworth’s donut-principles made their entrance. Remarkably, none of the previous reports contain a reference to her work on the donut economics. In May 2019, the first fruit of the collaboration with Kate Raworth appeared, building on the report from the previous year. The collaboration resulted in a new report Building blocks for the new Amsterdam Circular 2020-2025 strategy, involving many stakeholders from the sectors, food and organic residual flows, consumption, and construction. It resulted in 17 building blocks, named 'development directions'.
This report was based on the original 2012 publication on the donut economy. However, there turned out to be one pitfall. The original donut model was designed for global-level applications, which, according to Kate Raworth, cannot be directly traced to the urban level. The social implications of behavior in one city not only affect this city itself, but also the rest of the world. The same applies to the ecological aspects.
As a next step Kate Raworth invited representatives from Amsterdam, Philadelphia and Portland to join a task force and discover what a city-level donut model looks like. In each of these cities, dozens of officials and citizens participated in an interactive process. The result was a new model that uses four lenses to view urban activities: The first and second resemble the original lenses but applied at the city level, for example, the impact of local industry on local nature. The third is how activities in a certain city had a negative social impact on the rest of the world, think for example of clothing, produced under poor conditions. The fourth is the impact of local actions on nature worldwide.
These activities resulted in a new publication, The city donut for Amsterdam. It is an instrument for change that can be applied more broadly than to circular policy. In this publication, the new donut model is mainly used as a conceptual model. Instead of exact calculations, snapshots are collected as illustrations.
While city representatives were busy developing the urban donut model, the work towards the circular city continued unabated, resulting in the publication of the final circular strategy for the period 2020 – 2025 and the action plan for the period 2020 – 2021 at almost the same time. In terms of content, these plans are in line with the publication of the building blocks-report from 2019, including the application of the 'old' donut model from 2012.
In the following, I use both the strategy and the action plan to show the role of digital tools. At the end, I come back to the future role of the city donut.
Digital techniques in the circular strategy of Amsterdam 2020 – 2025
I align with the three value chains: food and organic residual flows, consumption and the built environment that are central to the strategy. Three ambitions are formulated for each of these three, further detailed in several action directions, each containing several projects, most with measurable results to attain in 2021. In addition, a couple of projects are described, that bare related to types of companies, institutions and the port. Finally, there are overarching projects, in which I will again pay attention to digitization, also because the role of the city donut will become visible here.
Below I briefly describe the three value chains, name the three ambitions for each, and give references to digital tools that will play a role within each of the three value chains.
Value chain food and organic residual flows
The municipality wants to combat food waste and reuse organic residual flows as much as possible. The role of regionally produced (plant-based) food will be strengthened in line with the Amsterdam food strategy. In realizing its objectives, the municipality participates in an extensive European project, Rumore.
The three ambitions are: (V1) Short food chains provide a robust, sustainable sensory system, (V2) Healthy and sustainable food for Amsterdammers and (V3) Food and organic residual flows.
Examples of digital tools
• GROWx vertical farm is a farm that aims to achieve maximum returns by applying artificial intelligence to the indoor cultivation of food crops, among other things.
• Restore is a measurement system and simulation model for Amsterdam and surrounding municipalities and companies that provides insight into the financial, ecological, and social effects of various forms of composting and bio-fermentation, including the use of biomass.
• The InstockMarket platform will map (surplus) food flows and - if possible - predict them so that the catering industry can anticipate this when purchasing. The data from this project will be linked to the circular economy data platform
• The Platform www.Vanamsterdamsevloer.nl makes all local food initiatives (including food events) visible and residents of Amsterdam can share news about food and urban agriculture.
Value chain consumer goods
The emphasis is on consumer goods that contribute substantially to the depletion of rare raw materials, their production is polluting and often takes place under poor working conditions. In addition, the impact on climate change is significant. The emphasis is on electronics, textiles, and furniture because repair is also possible in each of these cases.
Furthermore, a lot of profit can be made by good collection and reuse through sharing and exchange.
Here too, a multi-year research project funded by the European Commission is important. The Reflow project maps data on flows of materials and develops processes and technology to support their implementation.
The ambitions are :(C1) The municipality is setting a good example and will consume less; (C2) Together we make the most of what we have and (C3) Amsterdam makes the most of discarded products.
Examples of digital tools
• The municipality will develop digital tools within the (purchasing) systems that support civil officers in circular procurement.
• The West-district supports www.warewesten.nl. This website brings together the sustainable fashion addresses of Amsterdam-West.
• Using artificial intelligence, among other things, it is being investigated how the lifespan of various goods can be extended so that they do not end up with bulky waste. This can be used, for example, on the municipal website to offer the option of first offering goods for sale or for giving via existing online platforms before they are registered as bulky waste.
• Indirectly, it is worth noting that the municipality wants to make the use of ICT more sustainable by purchasing less equipment (for example through 'hardware as a service'), extending the lifespan of equipment and reducing its energy consumption.
Value chain built environment
This value chain was also chosen because the municipality has an important voice in what and where is built and in the development of the public space. The municipality itself is also a major user of buildings.
In terms of the built environment, circular construction can be achieved through large-scale reuse of construction waste. By ensuring that buildings can be used for more purposes, their demolition can be slowed down. Sustainable materials can also be used in the design of public spaces – from roads and bridges to playgrounds. In addition, consideration could be given to the climate-adaptive design of the city, resulting in cleaner air and dealing with increasing heat and rainfall.
The ambitions are: (G1): We do circular development together; (G2) The municipality sets a good example and uses circular criteria; (G3) We deal circularly with the existing city.
Examples of digital tools
• Introduction of large-scale application of material passports to have the most complete information possible on material use in all phases of the life cycle of buildings. This is linked to national plans, among other things by providing all materials with an OR code.
• Research into the possibilities of a (national) online materials marketplace. Such a marketplace will influence (local) material hubs, such as the Amstel III construction hub and the creation of circular business cases.
• Providing insight into the supply (demolition, renovation) and demand (new construction, renovation) of circular building materials and thus of circular material flows.
• Creating a digital twin of the public space and the subsurface to be able to furnish and maintain it functionally and circularly.
• Research in digital production due to the rapid development of digital production techniques and their applications, such as robots and 3D printing.
• Research into making the construction, equipment and water and energy consumption of data centers more sustainable.
• Research into which data about residents and users of buildings can be made public and which data should remain private.
The municipality could further simplify the process of permit applications by digitizing everything, enabling applicants to upload the necessary municipal data and construction drawings and calculating the BREAAM score. This applies to both new and renovated buildings.
Overarching theme: Data platform and monitor circular economy
On the road to a circular economy, a lot of data will become available and just as much data is needed to help citizens, companies, and institutions to make sustainable choices and to determine whether the goal of 100% circularity by 2050 is within reach. That is why a data platform and monitor is being developed. This numerically maps all material, recycle, residual and waste flows that enter, leave, and go around the city. This also makes it possible to calculate the impact on CO2 emissions. The data from the material passports and the materials marketplace are also integrated herein, if possible. The monitor also includes social aspects such as health, education, and equality. Relevant data will be open and accessible, so that it can be used for the development of new innovations and applications by the municipality and third parties, also to connect with other urban transitions.
The monitor connects to the four lenses of the city donut of Amsterdam and will collect the data that is currently missing to provide full quantitative insight. This also concerns the environmental impact of all materials that Amsterdam imports for its own consumption. Where the city donut is currently only a partially quantified, the monitor will continuously provide insight into whether the municipality is staying within the ecological preconditions or where it falls short with regard to the minimum social requirements.
Amsterdam's circular strategy and the resulting action agenda is ambitious and will inspire many other cities. Because many projects are small- and medium scaled, it is not yet possible to assess to what extent the strategy and action agenda help to achieve the targets (50% circularity in 2030 and 100% in 2050). Commitment to the development of the monitor is therefore crucial and the municipality will also have to keep an open eye on the parallel actions that citizens, the business community, the port and other institutions must take to achieve their share. After all, becoming circular encompasses much more than food and organic waste, consumption, and construction.
To document the process of the City of Amsterdam's adaptation of circular policy and the contribution of Kate Raworth, I have put together a brief dossier. This includes references to (copies of) all relevant reports and an indication of their content. This file can be downloaded by following the link below.:
