How to interpret the circularity dashboards

Outline of the video

0:01, Welcome to this new video helping you to best interpret our circularity dashboards.
0:12, Thanks to the urban circularity assessment, it assembles everything that we have measured, visualised and understood by carrying out the material flow analysis or the urban circularity assessment.
0:27, How does that work? First of all, whenever you are within a city you see up here how circular it is we see here, for instance, Apeldoorn, a city from the Netherlands, is 6% circular. It means that 6% of all of the materials that are processed meaning that are entering the economy and are used for consumption come from recovery. It means that these are secondary materials that re enter the processed materials.
1:06, What else can we see?
- This can be seen for the latest year, but you can always choose other years as well.
- 1:13, So, for instance, here we see the other big piece of our circularity assessment, which is called the Sankey Diagram, which summarises all of the flows and different categories of flows. So you see, here are the different families biomass in green metals in, metal ores in yellow, pink for construction materials and purple for fossil fuels. And you see how these types of materials go from one place to another.
1:41, So from imports to to processed materials, then it's energetic use, then its emissions or material use, and then it goes to stocks or to waste. This is an essential visualisation that helps us trace or follow how materials flow through the economic system of that city.
2:00, What is great, as well, is that over here, you can choose if you want another year. So this is 2014, and you see the different values for a different year on the right. Over here, you are able to see the most important circularity indicators.
2:21, But there are many other indicators, approximately 20. Here we have the five that, if we need to have a pulse of the circularity of Apeldoorn, these are the five that might be relevant.
- 2:33, The input circularity is the one we just mentioned.
- 2:37, the output circularity is when you divide the secondary materials, so the ones that we enter by the amount of waste produced. So we see that the output circularity, percentage of Apeldoorn is 9%. and then we see big quantity numbers.
- 2:56, processed materials, this is the amount of tonnes that enter the economy of Apeldoorn and our process to satisfy consumption and production needs.
- 3:08, waste, how much waste is produced by the economic system of Apeldoorn.
- 3:13, the secondary materials, how many materials are recycled, reused, , and all of the other ways that they enter back into the economy.
3:34, material stock maps, a spatialisation of all of the quantities of materials that are embedded within the built environment. You can see it for all of the buildings within Apeldoorn that are residential and non-residential.
- How much they weigh
- What is their typology?
- Is it more of a building?
- What materials?
- And therefore, you can imagine what type of policies you could create based on that.
4:17, Filters here that you can play around with. You see how much is the gross floor area for the entire place. You see how much they weigh in terms of tonnes and the average year of construction.
4:31, you can hover over any of the buildings to have more information.
4:38, when the city has carried it out as well, we have an in-depth analysis going to the construction sector, as before, there is a Sankey diagram and the main indicators explaining how circular or not this construction sector is with some explanation once again, and the same thing for the biomass sector.
5:03, contextualization: Apeldoorn has 164,000 inhabitants, and it has a surface area of 340 square kilometres. Now it's important to have these numbers to be able to compare it with other cities in case you want to compare the circularity. Although we're always very cautious about it, you need much more economic understanding, contextual understanding, territorial understanding to figure out how you can really compare circularity.
5:44, The last element that we have here are links towards not only the method that has been used to carry out all of this analysis, but also the data hub, which is the place where we have stored all of the data used for this analysis.
