This past fall 2014 semester at ESA, students were assigned to become “Super Concerned Citizens Special Investigators (SCCSI)” and make a movie summarizing their findings about e-waste. I am very proud of my students and I thank them for their dedication this semester! I am not uploading the videos because some have used copyrighted sound material… Anyway… Below are their stories:

We tried to investigate how to repair a computer that could be considered as reaching its term of life. After looking quickly into the solutions given to us by asking to a certain number of shops (big corporations and small repair shops) we decided to record ourselves into a journey of finding a solution to this problem. The main thoughts that guided us was; is this piece of electronic built to break down and will it be possible to repair it in order to keep it as long as possible? We began our investigation thinking that all the different shops had the same answer to our problem: by replacing our old device by a new one. After dismantling our device and comparing it to newer product we arrived to the conclusion that trying to perfect a product in its weight or thickness, can, with the time, make it more and more difficult to repair especially by making custom made parts or replacing a simple screw by a weld attachment. We can relate this issue to the new ways of designing objects and architectures today; are we building to last or to replace? Is there a programmed obsolescence in architecture? Can we replace a “Gehry” part as well as a “Prouvé” part?

Love2recycle is a website which proposes a solution to collect electronic waste and sell it through the platform. The company buys the old phones for a cheaper price, repairs it and sells it back to other parts of the world. But, how can I make sure that my phone ends up in good hands when I use online recycling platforms? I decided to make my own research and I called the company. By investigating the system, I found a lack of transparency: phones are going sooner to the trash and it increases the quantity of e-waste.
Who is to blame? Who is responsible? Who cares?
The solutions are terrific in the short term. But wouldn’t it be a little more green if companies encouraged consumers to change consumption habits altogether?
The city has evolved… and we are becoming more and more dependent on the machine. Phones have become the extension of our bodies. People are left aside. Design and technology are excluding the person who doesn’t have access to new products. There is a digital divide which creates a huge discrepancy. The society is designed to exclude you when you don’t have a phone.
How can you pay? How can you call?

From the moment of purchase of an electronic to the day it is no longer functional, what can we do as responsible consumers to deal with our e-waste. I have looked into my options, and although repairing the object is probably the most popular option to follow, I decided to represent the part of the population with limited technical ability: The non-repairmen and women. Why throw away in the trash when you could give it to someone to make good use of it? The real question is, however, how to find people in need of your e-waste and be sure they are not just another person planning on selling the e-waste for profit? After finding a website that links people willing to give away their object to others willing to take it for their own use, I decided to do a trial and give away my own e-waste. There was instant demand for my iPod, and I was overwhelmed by the number of requests I received. Of course that raised another question: Who are these people requesting my e-waste and which one of them is truly in need of it? With all these unanswered questions, came an interesting twist of events: I realized that my iPod was not broken… it just needed to be charged. Suddenly, I was no longer willing to give away my electronic… This change of heart illustrates the sort of relationship we have with our electronics. We feel possessive of our electronics in their functional state. However, they lose their value once they are broken or out of style. It becomes so easy for us to abandon what we once cherished.

Where Does the E-waste go?

During our short investigation, we tried to answer a question that bothered us as citizens living in a big city: where does all our e-waste go?
When we started to follow our piece of e-waste from the street, we expected to find an answer to this question. But it immediately became clear that it was not going to be easy. After the many bureaucratic obstacles we encountered, we decided to examine whether and what other citizens of Paris think about the daily waste they throw to the street.
Almost everyone answered the same way. The place where the e-waste travels to is UNKNOWN. Surprisingly, even people who worked for the municipal system did not know about the destination of the waste after they leave it in the street. The most surprising fact we discovered was that nobody seems to care about it…
Life in modern cities enables us to ignore some of its constituent systems, if we prefer not to do so. Impressive facades hide poor neighborhoods, underground systems maintain sewage. Thus, life seems to be easier, compared to the past. Nevertheless, it should not be an excuse for responsibility diffusion. We created this animated movie in order to raise the awareness of people to their property, their e-waste.
By a simple web search it is possible to learn about the terrible pollution in African countries caused by toxic e-waste. The information is very accessible but only few people are interested in that and look for it.
How can we, as responsible citizens, take responsibility and change this undesired situation?
There are many answers to this question. what we want to focus on in the future is how to use design as a tool in order to raise awareness and transparency about the life circle of the product we are using, and not only to know where it goes after its broken, but also how it is working.
As architects and designers, how can we integrate in our design the transparency, and design a product who could tell a story?
When the first computers were invented, people saw them as magic boxes. Today, it seem like it never changes. Our whole life going around our smartphones, televisions and other electronic/electric products, but because everything is hidden behind plastic and glass, we can never understand how this product really works, and people don’t really care about what is inside their machines. Maybe we lost something on the way… maybe it’s the curiosity, or the desire of knowledge. If the product works we use it, if it breaks… we buy a new one.
If we would understand more how our electric product is working, maybe we would care more where they go after they break. Making it invisible to understand and easy to fix can decrease the amount of e-waste in the streets and in poor countries.

This movie shows the process of recycling an e-waste, in this case a laptop, in the city of Lima-Peru. Because the process took place earlier this year, the story is shown as a kind of chronicle of what happened and the things I learned about the infrastructure and system for recycling available now in Lima. This story takes you with me throughout what I learned in that moment and what I am learning right now about the limits and opportunities for e-waste inside the informal and formal systems simultaneously managed in my everyday live. Starting from getting the laptop, the life spam that it got, the process of recycling it, and the realization that not everything is as simple as one first imagined. The process doesn’t always end where we want it to; and it is up to us to finds alternative ways to deal with the challenges. That is what makes us Super Concerned Citizens Special Investigators.
Architecture here plays the role in two ways: in the overall design of better infrastructure for not only separating and classifying but for actual recycling of technological goods; and as a designer in the questioning of how much of a laptop can be turned into other goods. How can we recycle something that is not designed to be recycled? And even if it is meant to be recycled, how can we accomplished that if the infrastructure doesn’t exist? Who is to blame? The starting point of the process or the last?

How can we decrease e-waste?
When a smart phone part breaks, we usually buy a new phone… and this even if only one component breaks.
Could we make a new product using the working parts of a smart phone? Can this practice of making new items out of working parts of a broken phone decrease the production of e-waste?
We asked an expert about making items out of parts of phone parts.

In the past few years headphones market have known a fantastic growth with the multiplication of portable players like mp3 players, iPhones, tablets among others. They have since then become a fashion accessory and as a result many brands release new models every season leading people to consumerism and to change their headphones every other month. In many cases they extremely fragile and have a very short lifespan; yet, the truth is that most of the broken headphones work perfectly and you just need to solder the wires together again. But instead the entire product is just thrown away. Is it an intended weakness?
In this video I tried to show how the (Dis) Assembly process of an object can dictate the evolution of this waste chain. I also try to raise awareness of the consequence or our acts and current education. Most of the waste produced in the world is produced by the construction industry. Architects and designers should acquire a basic notion of the way their products work. They should learn not to systematically rely on others. They should enrich their culture and reaffirm their knowledge in their field. Architects and designers should learn to properly analyze a situation to better re-use or repair instead of always starting from scratch.

As part of a research on e-waste, I decided to investigate what are the possibilities existing with a broken device, in my case, an old iPhone that wasn’t being use because it was damaged. Time is an inevitable degrading factor that must be managed in order to guarantee the longest lifetime of objects. Getting rid of old devices is not a solution, because that it is moving the e-waste from one place to another, and because this devices are actually still useful; therefore my final goal was to keep the phone in a usable condition. The idea is that everything is going to get damaged and old with time, and the solution is not to be afraid and get rid of the products or get new ones, but to foresee and maintain. Time is the agent that can make an antique of an old car, but it can also cause structure to rust. The solution is to reach for the tools we need, and that are not given to us, to apprehend the influence of time. We are powerful among creations and not the other way.

Plastic Micro-factories in Agbogbloshie

Pellet made by extrusion process

Plastic waste in Ghana has become a major social and ecological problem, due to the adverse effects of plastic pollution on both human health and the environment. Especially during periods of flooding, plastic waste chokes the drainage systems of most Ghanaian cities.  The need for initiatives to improve sanitation in our community is of great importance. Of the many local waste management companies, only few practice segregation and recycling of waste — and not yet at scale. In the area of plastics recycling, Blowplast recycling is one of the formal organizations which recycles water sachet and black bags in large volumes. What a lot of people do not realize is that plastics recycling in Agbogbloshie is a major activity within the informal sector recycling industry.

Because we are current developing a plastics micro-factory as part of the AMP toolset (one of first prototypes is a mini-kiln for moulding plastic tiles), we continue to work with Agbogbloshie plastics recyclers in order to better understand how the process works now and how it can be improved.

One of the more advanced industrial setups we have come across is located on Abosey Okai Road. Stages in the process flow include sorting, shredding and pelletizing. This micro-factory engages more then 20 youths in Agbogbloshie in full-time employment! The sorted plastics are ground using a milling machine (see picture below) which is connected to a water bath. Shredded plastics are then collected and dried. Finally, the shredded high-density polyethylene (HDPE) are pelletized using an extrusion machine. These pellets — made out of plastic waste from all over Accra — are then sold as feedstock to formal industries both in Ghana and globally that have the capability to produce plastics films.

The existing model of plastics micro-factories in Agbogbloshie deserves support and attention. In effect they perform a massive public service: cleaning up the city of Accra, by making profits from our plastic waste.

Prototyping a Laser Spectroscope

Materials are usually classified according to their physical and chemical properties. New technologies today are making the identification of materials increasingly simple, fast and reliable. Building on our earlier research in using spectroscopy and the physics of light to visually differentiate materials, we are now ready to ask: Can we make a laser-induced breakdown spectrometer, locally in Ghana?

Two physics teaching assistants from the University of Ghana signed on with AMP team to help us find out: Nutifafa Y. Doumon (who already participated in #ampqamp), with an MSc degree in Nanoscience from University of Groningen, in the Netherlands and Rodney Abugre, who recently graduated with an MPhil in Physics from University of Ghana.

We first reviewed existing technologies and later performed our own experiments. Materials were sourced from Agbogbloshie, since the device will be used to test scrap metal from that location.

The goal for our first three experiments was to investigate the laser excitation process of the material surfaces. Apparatus include: Laser light source, converging lens, sample holder and timer. In the laser excitation process we expect the electromagnetic energy of the laser light to be transformed into thermal energy inside the metal and this based on the amount of energy absorbed by the metal. In our experiment we tested this principle using red laser of power 1 mW & < 5 mW, and an incandescent light of power 100 W. From the test experiments, we conclude that due to low power output of the laser light available, we cannot obtain the desirable results from the experiment (See pre-lab here).

The next step was to set up and calibrate the complete optical path with components such as, prism, diffraction grating,  laser source, lens, filters mirrors and a camera. In this optical system, our major need is to find a laser with high enough power output to help us obtain the correct spectrum through excitation process.

We will use this system to record the spectrum for the different materials, analyze them using MatLab software and compare results to literature.  In the latter stages, the Agbogbloshie community will be engaged in a workshop on spectroscopy.

Plastics constitute a significant portion of the Agbogbloshie waste stream, moving through stages of collection, sorting (by type and colour), cleaning, shredding and even in some cases molding into pellets. (See Plastics blog post). With at least 7 micro-factories by our count, Agbogbloshie is a key part of the plastic recycling industry in Ghana, and integrally interconnected with both local and global production cycles. To date, the failure of Agbogbloshie’s industrial ecosystem to add value to plastic material recycled on-site is a lost opportunity for local manufacturing.

Building on our experiments with plastic during AMPQAMP and drawing on the knowledge and expertise of oven fabricators based on the ground in Agbogbloshie, we are now co-designing and prototyping a mini-kiln. This week, William Mensah completed fabrication of the first  prototype in Accra Timber Market,adjacent to Agbogbloshie. The mini-kiln fits the standard module of the AMP spacecraft and is one of the first tools from the AMP tool-set developed to plug into the community workshop.

The prototype, is composed essentially of a frame of angle bars,  inner and outer layers of sheet metal with a layer of what is locally called “fibre” (PUR foam insulation sourced from air-conditioner dismantling). We didn’t finish until evening, but couldn’t wait to test. Hence using shredded plastics from Agbogbloshie, we  made new recycled plastic tiles, heating the the plastics to their melting point, and allowing them to cool. We intend to carry out carry more of such low-high tech plastic experiments soon in our spacecraft. Stay tuned for more and be sure to share with us, your innovative ideas regarding plastic recycling.

Agbogbloshie Mobile phone surgery

Dis-assembly of mobile phones constitute an increasingly significant facet of the e-waste industry here in Agbogbloshie. Metals from these phones form part of the urban mined resource of the city, albeit not as ubiquitous as other equipment such as refrigerators, and microwaves.

Dis-assembly of mobile phone by an e-waste worker in Agbogbloshie

As part of the process of making the AMP’s E-manuals, the team with its Agbogbloshie field agents and members of the AMP makers collective (Sam and Iddrisu), disassembled a mobile phone at Agbogbloshie. We made use of the most available tools, (mainly screw drivers owned by the e-waste workers themselves), and carefully took apart the phone, in a manner that preserved each component. We then identified and documented via photographs, each of these. Such hands-on dis-assembly activities enables the team (with diverse backgrounds), to understand better, the nature of the electronics that are in Agbogbloshie.

Documented phone parts

As it is with other equipment in Agbogbloshie, mobile phones that arrive here are usually in a wide range of conditions. Those in fairly good condition are resold altogether or have their working parts sold to phone repairers(who troop in, in search of such working parts). Those that are in totally bad shape are scraped for constituent metals. It is common to find that, phones arriving here for dis-assembly already have missing parts and/or components such as batteries. According to the e-waste workers, these are sometimes removed by collectors before they reach Agbogbloshie. Some of the most valuable parts of the mobile phones inside Agbogbloshie are the screen and circuit boards. Once these and other parts are removed, they follow the same process as other e-waste and are either sold locally to phone repairers for re-use or to middle-men.

 

 

Agbogbloshie Material Metrics

The E-waste processing industry in Ghana has in recent times attracted much interest and research. However, one major hurdle in researching this urban phenomenon is inadequate records on volumes passing through such places as Agbogbloshie. This situation makes the task of describing it with specific and accurate numbers very difficult. Motivated by this, the AMP team has undertaken to gradually map out the quantities of metals passing through this most complex open air factory. On the map below are GPS locations of burning, dismantling, mosques among others in Agbogbloshie. The GREEN points indicate weighing scale locations.

In collaboration with our field agents, we devised a simple way to quantify the volume of urban mining happening in Agbogbloshie. First, we  mapped the scales (see picture above), which are the points at which large volumes of metals are weighed.

We then proceeded to collect on a daily basis, the amounts of scrap metals weighed at these places. In what we considered to be the pilot phase, we recorded over a three week period, the figures from a select group of scale owners and then, analyzed these graphically.

graph all material graph value graph 3

One finds, there are ferrous metals, non-ferrous metals and plastics. During the process, we realized that, significant volumes of steel from such large equipment such as cars are not weighed due to their sheer size. They are rather sent straight to steel processing industries such as those in Tema. Hence, even though the graph indicates aluminium as the largest, this only refers to household appliances that are regularly weighed and documented. In the future, this “lost” data will be retrieved from these industries. At the current rate, copper is the most valuable metal ( 7 GHC/pound) followed by brass(4 GHC/pound) and aluminium (1.5 GHC/pound). When it comes to plastics, the most commonly processed are polypropylene (PP) and high density polyethylene (HDPE). At the end of the month of November, the team will go on a massive data hunt, collecting on a much larger scale, this kind of information from all over Agbogbloshie.

You are welcome to volunteer!!

Spectroscopy for 3E-materials ID

E-waste workers in Agbogbloshie determine material type based on experience: years of dismantling and disassembly, visual examination and use of magnets to identify ferrous metals. However, in order to improve recycling practices — including protecting workers from hazardous materials — more advanced methods are required for identifying 3E-materials (i.e. materials present in Electrical and Electronic Equipment).

For the past few months, AMP team has been researching one technology that can help — spectroscopy, which detects the wavelengths of light unique to each material. First, we built a paper spectroscope that enables us see various spectra of light. Other DIY projects we have tried include foldable mini-spectrometer, and cd spectrometer. We used the spectral workbench software to analyze some spectra of light from different sources we recorded. Some of the sources were white florescent, blue light and candle light.

The goal of this research is to build a spectroscope that enables us to analyze the elemental composition of scrap materials in Agbogbloshie. A promising technique for identifying chemical elemental composition of a sample is called Laser Induced Breakdown Spectroscopy (LIBS).  Another DIY project of interest to this research is the ramanpi spectrometer which is based on raman spectroscopy. These and other techniques will be explored to achieve the goals of our research.

Talking African Innovation

“Africa needs meaningful investment to alleviate poverty and provide inclusive prosperity. To achieve this, we need to be able to provide environments that promote quality investment for the people and reduce risks. Forums like the IPA are necessary to make the most of the continent’s investment,” AgriProtein spokesperson David Drew (Winner of IPA 2013)

Typically when the world talks innovation, Africa is not part of that conversation.  However, people living on the continent know that is both oversight and misconception: the vicissitudes of daily life in African environments engender strategies and tactics for survival that are radically innovative. Unfortunately, in contradistinction to this reality, a majority of African educational and research institutions underperform at driving innovation to address the challenges of daily life in these same spaces. Too often the emphasis is on “pure” academic research divorced from real-world applications. Or when research does link to applications, that coupling does not include viable implementation plans to bring the ideas to market or to scale. Africa has an abundance of brilliant minds. What is missing is a results-oriented ecosystem to translate indigenous invention into products and services that can transform society. On the evening of October 1st, a dozen young Ghanaian innovators and changemakers joined with the AMP team to welcome Pauline Mujawamariya, Director of Innovation Price for Africa (IPA), at the Hub Accra.

Now in its fourth year, the prize continues to increase its profile globally, the size of it’s pan-African community of innovators and concomitant capacity to shift the conversation about innovation in Africa. An emerging force in the global innovation discourse, the IPA prize — an initiative of the African Innovation Foundation — provides support for significant inventions by Africans in Africa, not just to honour the winners for their ingenuity, but to help their inventions become true innovation through market-based delivery. This year’s winners were Dr Nicolaas Duneas and Nuno Pires from South Africa, who developed an Osteogenic Bone Matrix (OBM), the first of its kind in the world. This invention is straight out of science fiction: “The OBM injection leads to the rapid, safe and effective healing of problematic bone injuries, leading to the complete and natural restoration of the bone, including the bone marrow.” (1) Yes, that means an injection that makes bones regenerate.

IPA 2013 winner AgriProtein went on to raise “$11 million from strategic partners to commercialize and globalize its IP.” (2)

After setting up the bamboo furniture “living-room style”, we dove deep into a two-hour long discussion about the nature and future of African innovation. Pauline gave a brief overview of what the Innovation Prize for Africa was about and then engaged attendees — all either founders of or actively involved in technology start-ups — as they asked questions about the IPA prize, shared their personal experiences and the challenges of youth-led entrepreneurship in Ghana and West Africa. Topics ranged from “problems”, i.e. social and cultural factors that inhibit innovation, to countermeasures that can lead to solutions (over time).

Far from being a talk shop of hopeless complaints, one could sense a joint resolve to take these insights and turn them into action. The atmosphere was charged with electric potential energy.

One part of the conversation worth sharing… We debated whether the IPA Prize reinforces the “false myth” of innovators as lone geniuses, when in reality, innovation occurs through the interconnected efforts of groups of people (networks), not just individuals. Could not the IPA be more effective if it supported technology clusters or collaborative projects? Pauline’s response was that while innovation is a joint venture, leaders still play an instrumental role in making innovation happen. The IPA Prize seeks to ensure that pioneers receive the attention and support that can enable them to facilitate the massively-scaled change that the continent needs so urgently.

Which leads us to… Applications for the IPA Prize — which awards $150,000 in total to winners — are due at the end of this month. Already around the social web, we are seeing retweets and Facebook shares encouraging people to “Apply to the prize!” This is great, and we support it. You SHOULD apply. It’s more than about simply winning. Going through the process of applying, or even talking about applying, can serve to remind you that you can be and likely ARE an innovator already. Everything starts in the mind, and once you see the power you have to affect change, it becomes infinitely easier to make it happen.

But we want to add something else: Encourage other people around you to apply! African culture is predicated on the concept of community. When you raise up one person, you raise up everyone. YOU know the people around you doing amazing things. Even if there is no direct benefit for you, encourage those people in your circles and networks who you admire — who inspire you — to apply to the IPA prize. Sometimes people may not even see how amazing what they are doing is. They need someone else to help them see it. This applies especially to youth under the age of 25. Talk to the “whiz kids” that you know that have created things — just because they wanted to — but which they may not see as inventions.

The deadline for entry is 31st October, 2014 and we hope to see as many youth (under the age of 25) and women as possible enter and win the prize. Together we can redirect the conversation around innovation in Africa.
