Dear Save Sand team members,

First off I think your SDG in progress platform is quite complete and intelligently constructed. I thought it was a good idea to add the evolution of your conversations and findings which we could tell went hand in hand with the progress of your project. I think it would be nice to add a small section as a starting point to explain what you're trying to do exactly, your goal, ambitions etc and perhaps why it's important.
As I am also working on the Beld and Road Initiative, for selfish reasons, I would have liked to see the precise reasons as to why you gave up on the idea altogether.
PS: you may already have read this article, but I thought it would interest you: https://www.researchgate.net/profile/Praveen_Biradar/publication/323239519_Recent_Trends_in_Replacement_of_Natural_Sand_With_Different_Alternatives/links/5a87c3c1aca272017e5ac3c6/Recent-Trends-in-Replacement-of-Natural-Sand-With-Different-Alternatives.pdf
This paper presents a review of the different alternatives to natural sand in preparation of mortar and concrete.

All the best for the rest of your project!!

This week, we formed into our group - Davide, Anna, Alessandra, Donata, Maja and Hanaé. 

We all agreed to look at the construction side of the sand crisis, and the link in the Chinese context. ​

We were also exposed to the idea to work with the X Factory in Hebei, China, as they are very involved in alternative construction.

Week 4 (25-26/10)

We decided to focus on the Belt and Road Intitiative following a presentation of Geospatial Analysis. We decided to map the flows of sand in this Chinese project. 

Our aim was to focus on the environmental costs related to sand in the context of the Belt and Road Initiative (BRI). Which materials are sand-related? Which of these are used by the companies and actors involved in the Initiative? Who are really those companies and actors? By identifying the sites where sand-based construction materials are used, the objective is to create a visual tool/map localising the environmental costs related to sand on the Belt and Road. The aim is to also provide local-based solutions/recommendations for the most sand-intensive locations to move away from sand-based construction materials. This project has a transboundary scope, and focuses on scaling the issue of sand usage in the BRI.

USG survey - lithographic analysis of the world

How can the chinese authority could help - financing authority AIIB, authority behind BRI (environmental and social standards)

chinese solution - their own high ecological civilisation - national development plan - how do they export that to other countries? where to put national parks, source of wealth to have green. how to export domestic standards on the belt and road initiative?

provisions on particular types of sand that should not be used, no-go zones areas very sensitive, recycling construction waste? Close system of construction, circular production cycle,

biodiversity hotspot map, overlayed by lithographic data (pascal) - three/biodiversity layers

  • lithographic - sand is, rivers are

  • sources of sand

  • biodiversity - endangered species, protected areas

  • map of the roads itself

2 parts: demand (quantification, order of magnitude) and

how long the roads are, materials, how much concrete used (data on paved roads in the roads, WB, find a civil engineer to find out the proportion of sand in roads),

EIA standards,

Sand is sourced in the area that it is provided because of transport cost

Distance differential between the rivers -

where do you keep your supplies? Freshwater sites, biodiversity hotspots

 

third part- what kind of provision of best practices make for no-go zones, what kind of standards regarding biodiversity? with national partners without the means to implement the laws

The evolution of your project must have been challenging, but it has allowed you to grasp the context of construction and alternative materials more fully, and this is apparent in the research that you have done. I am impressed with how solid your research is and how proactive you have been in contacting people who can provide you with insight or support. It is a shame that some of the notes are a bit difficult to follow due to their conciseness, for example, it would be interesting to better understand how GIS can be employed for your purposes - but I look forward to discussing this with you in person! All in all, very exciting project and the amount of work and resilience you have contributed is humbling.

Davide had come across articles about a project created by a Chinese artist in Beijing ("Nut Brother"), who had used a hoover to suck Beijing pollution during 100 days, and manufactured a brick out of it. https://www.theguardian.com/world/2015/dec/01/chinese-vacuum-cleaner-artist-turning-beijings-smog-into-bricks

We all found the idea interesting (because it also links back with the X Factory, which was our initial point) so we made more research.

In fact, another Dutch artist (Roosengaarde)had built the largest air vacuum cleaner in the world and installed one in Beijing and one in Tianjin. The aim was to create pollutionless parks. He ended up with a certain quantity of carbon dust from this pollution he sucked from the air, and he decided to create jewellery out of it. https://studioroosegaarde.net/project/smog-free-tower

We thought that merging the huge issue of pollution in China, which is very know nowadays, with our issue of sand extraction, was a very enticing idea, so we decided to go further into it. 

We contacted both Nut Brother and Roosengaarde, but with little success.

I think the idea of combining the sand crisis to the pollution problems that China is facing is amazing! I really like this idea.
Also, if you able to partner with Tsinghua or xFactory, we could see the continuation of the project next year!
Is the project going to be aimed towards finding viable alternative solutions for construction or will its main purpose be raising awareness?
Keep up the good work!

We then decided to think about how we could use air pollution particles as a way to build differently.

  • table with alternative materials’ characteristics/parameters: like life cycle, carbon, is using renewable energy/waste? [strength, fire resistance, paint]

  • at the end -> this material is very good to build that thing -> one solution is good for one application

  • How to produce this kind of bricks

  • graphic designer -> design a model of house (use models of china) and what part of the house can be made of the alternative materials (e.g. just internal walls)

  • final info for each product: what can be done with this material?

Using waste to produce construction materials needs to be handled with care. Since the quality of waste material which is being used needs to monitored as the end product, cement/concrete will be in direct contact with humans/living beings. More academic research and large-scale case study can help to understand it better.
Eg. Waste can have heavy weigh toxic elements such as Mercury, Chromium which are also cancerous so robust quality management is required.

Thomas Maillart put us in contact via WeChat with Grissom at X Factory in Hebei, China. While chatting with him, he found the idea very good and asked us how we needed the X Factory to go further. We planned a video chat call for the next day to discuss it. 

We prepared questions for the call: 

Questions for XFactory

  • Feasibility of low cost machine?

  • partnership with colleagues with the glue?

  • general interest of this project

  • does the machine already exist? why don’t they already work?

  • What are you focusing on air pollution? what is your specific focus?

  • do you know how to make a brick compact that doesn’t break

  • what are the standards? could we build with it?

  • can we use the wind/renewable energies to energise it?

  • new projects to go there

  • we can go there and be helped to find people to let tus know what’s going on here

  • cooperator in Hebei province -> collecting new materials around the world -> they are try to build a exhibition? -> they are just collecting new materials

  • technology not from China

  • government reduce pollution by shutting down polluting companies but

  • organic gloom to start dust in the ground -> dust on the ground -> during the years pollution is getting better

  • short term -> collect enough dust

  • there dust from ground -> Hebei province -> mine area -> different kinds of pollution and dust -> too different

  • what is the source of dust -> how to solve the problem from the root ->

  • brick is very weak ->

  • solved polluting dust with water on the street -> place around cities ->

  • Organic glooms in water and water spilling vehicles -> but cannot collect dust -> cost very low

  • Transportation cost very high so construction materials  must be built in place

  • bicks not feasible solutions -> very strict laws

  • concrete industry very pollution -> how to help them to pollute less -> concrete uses few sand.

  • sand from the rivers and in the place around oceans and seas is illegal because there’s too much salt

  • sand is not a big problem in China

 

 

 

  • Waster after the construction? what do you do with the alternative after destroyed?

  • Public health issue?

  • raising awareness focus via Tsinghua and academic

  • zero energy house concentrate on energy use by people living inside, but the construction materials are also very important - zero energy competition --

  • Long term solution? What do we use when there is not more pollution (maybe in 5 billion years)?

pollution coming from the northen industrial regions is polluting the cities. air pollution very bad. they are funding many new projects. come there for free and they help fund the people that have ideas, tech

Company in china, shanghai city, new kind of materials all around the world,  they already use pollution dust but technology is coming from other country not China. just collect the materials.

Hebei province very polluted

economic efficiency of the technology

organic glue to stick dust on the ground, so wind doesnt bring that into the air.

mining area, industry dust→ different sand

they try to solve the solution for pollution

they collect dust with water+glue in the city, just in the cities, but places outside the cities no. water+glue, dust stuck in this paste and it falls on the water and stays on the ground.

Transportation cost high. constructions materials have to build near the construction place. very strict restrictions for environment to produce bricks. the real problem is concrete industry. in china there is not much sand. From the bottom of the rivers. collect water from sea not possible because of the salt and it weakens the concrete. problem with sand is in the northen regions.

Our project → suck pollution and make bricks.

 

PROBLEMS:

  • In China they do not really use bricks.

  • they also have strict environmental rules to make bricks

  • They do not import sand. The sand taken from rivers near the construction place.

  • Not enough pollution dust to make a brick

  • They mainly use concrete and cement → so bricks are not really useful

1. As mentioned bricks are not used, one idea is to how to use the dust to create cement may be, since cement can incorporate particles of small size. In India, the government has started using fly ash (residue from after burning the coal) in cement industry.

Switch from OBOR to alternative material for construction (construction of brick that could be made our of pollution particles)

We changed our project because it seemed to vast, and too few resources and data (no details for the map and no real transparency of information)

 

We were stuck at the materials part. We found the example of Roosegaarde Studio who created a huge vacuum cleaner in beijing and Tianjin to suck in pollution particles from the air and create jewelry out of the dust. We then wanted to use that idea to create an alternative material to concrete. We decided to contact Roosegaarde but we received the response that they were not working on this project anymore so they were not interested in this partnership. We also contacted an artist who used pollution dust and made a brick out of it. however, we didn’t get all responses.

Thomas made it possible for us to see the project more clearly and with more confidence as he put us in contact with the X Factory on Wechat. We also talked to Jean-Marie who helped us define a first prototype of the brick with legos in the FabLab and dust from the laser hoover. The X Factory contact suggested that it was a great idea and supported it completely. We set a video chat meeting with him for the next day.


 

Critical perspective=

  • financial cost, cost estimate is enough (Louise)

  • quality

  • energy of the machine (Thomas)

It has been very interesting to learn about your iteration and openness to discovering new paths. It's also interesting how you can learn beforehand where the pitfalls might be hiding.
The constraints you have been encountering could be an opportunity for narrowing your scope, as well as an analysis of the actors involved. You probably have them well identified already, but would be interesting to identify throughout the journey specifically whom would be the beneficiaries from the project.

Integrate the different pollution issues with sand issue → plastic reuse, wood bricks,

impact of art and culture to awareness on environmental social problems

circular economy, nature science

we need to catalyse this kind of innovation through art? this would be the second step

The intersection between art and tech can be very exciting, particularly because it allows the issue to become a cultural phenomenon and appeals to the senses as well as the rational mind. This can have a surprisingly strong impact on society in the best case scenario. However, the end product can also be a bit too marginal to have a real effect, so it is important to consider whether it is worth the effort.

First of all, I would like to commend this whole group for the amazing evolution it has gone through over the past few weeks! You've gotten past many obstacles and have already gotten firsthand experience with how difficult it can be working on projects like this, and I really want to congratulate you on this!

I really love the direction that this project has taken. It is addressing a huge issue in this industry which will be the follow-up question to people learning about the sand crisis- what else are we supposed to use? I know you're still in the planning stages but it looks like you have an effective method for measuring the alternatives that you explore, and creating this categorisation table will probably be very helpful as the project evolves.
It would be great to see the data and conclusions drawn from this project shared somewhere, so maybe identify a target audience or group that you can "present your findings to" so as to think about how you present the information. Example: if you wanted to show this to construction companies, maybe really focusing on the monetary aspect and financial sustainability would help.

Also, when we came up with our 100 solutions during the workshop, I came across this website and really liked some of the ideas so maybe you could use some: https://inhabitat.com/11-green-building-materials-that-are-way-better-than-concrete/

Again, great job and I'm excited to see how the project turns out!

Your team went through lots of iterations and had lots of brilliant ideas! It's impressive how you tried to stay positive and continued pushing for new solutions and alternatives. This is what innovation is about!
I think that you are now on to something great! There is definitely a need for new materials in the construction industry so it's good that this is what your group is focusing on these solutions.

The point discussed were: 

  • the disproportionate demand of sand in China
  • the dependency of the construction industry on cement (a sand-based material)

While we were all very enthusiastic about the idea of working on the BRI, our various exchanges and research have made us realise that it was too big a scope and that the data was not open to the public. This was indeed a dealbreaker as our mapping project would have been based on detailed information.

It would be more helpful if the team can provide more explanation of the limitation on this idea. As the BRI concept note s quite elaborative, it would be helpful for us if there is a pointwise explanation that why this idea can not take off!

The project is to merge and connect art and scientific knowledge, in the context of the global sand crisis, a crisis that surpasses borders. By doing an exhibit demonstrating the necessities of decreasing the demand of sand in construction, we aim to convey the sense that art can help in attaining the public and the private sphere by finding new and unconventional ways to build. In that sense, this exhibition will present the possibilities of new ways of life.

This exhibition will use Virtual Reality to provide accessibility. We recognize the cross-national scope that the sand crisis reflects. We call “visitor” the VR user. The visitor will enter the exhibition as a “new world” where the sand presence will be considerably diminished.

Through the showing of different part of the exhibition, each containing several pieces of art, the visitor will first go through the various negative effects of sand: the scarce resource of sand, the intensity of its usage, the impact on biodiversity, beach erosion, illegal mining and child labour, urban pollution. The second part will introduce different artistic but realistic ideas of how to build by using other materials. In doing so, we will show existing and interesting alternatives that everybody can use and exploit in everyday life.

The challenge is to touch different types of people by mixing art and science. It will enable the shifting away from the sand dependency by using art as well as scientific exhibits.

Nut Brother is a major inspiration. He uses environmental issues to convey art touching general public. He referred to drinking water and air pollution, we wanted to extend it to the sand crisis.

 

We contacted him on Thu 15/11 by video call. He is ready to help us. 

 

  • Brick is a part of the building now -> artistic mean

  • Industrial vacuum cleaner -> bigger battery and painted (7100 RMB-> 800/900€)

  • He sends us: Video of vacuuming and one other making a brick

  • We send him information about sand issue? YESSS

We started with the idea of the art exhibition in the idea B, but it was in the long term. 

During week 6, we finally had an answer from Nut Brother, which made us realise that we could use art as the central part of our project. 

After long discussions, we ended up coming up with different very good ideas of art pieces that could be designed as a real art exhibition about sand. We expanded it in a way that we could show alternative materials in that way and use art as a bridge to find scientific alternatives.

The idea of doing an exhibition about the sand issue has never been done before. The fact that it is in VR makes it close to people’s intimacy. The artistic experience of the visitor will be quite unique, but it will also convey unconventional materials present in our day-to-day life. The perspective under which it is shown is totally novel for the public who has not even heard about the crisis. This merging of different non-traditional elements makes the project absolutely one of a kind.
