Yes, I would like to receive emails from HOBI International. The views expressed in this article are those of the author alone and not the World Economic Forum. "We are now at the experimenting phase in Europe," says Dr Kees Bald, of the United Nations University. It also contains the less valuable but still significant aluminium (25g) and around 15g of copper. The remaining 43 million tonnes of e-waste, estimated to contain recoverable material worth around US$55 billion, is not recycled, and is landfilled instead. Source: WEF; Lewis2011, The Global E-waste Statistics Partnership, 2018. To build a circular economy for electronics there are different aspects to consider. However, the push for a more circular future that takes into account the environment and people living in it will not only depend on the companies and governments, you will play a crucial role in it as well. Second-hand electrical goods are worth more than individual components, which again are worth an order of magnitude more than the materials alone. Global demand for electronic goods is soaring how many phones and laptops do you have today, compared to 10-15 years ago? There could also be incentives paid to manufacturers to make their products more easily disassembled.. The future is bright!

Companies should be ready to repair equipment they sell, something that has also been mandated by law in some countries. It takes 1.1t of CO2 to mine and produce an ounce of gold from primary mining, explained White. Both plants will likely be in the UK.. Despite this, hundreds of thousands of tonnes of e-waste are sent every year from developed regions such as western Europe, North America and Japan to developing countries such as Ghana, Thailand and India. The process of recycling e-waste is not without its problems, however. And one of the most appeal aspects of Sahajwallas solution is that while traditional mining is labour-intensive, e-waste mining can be highly automated.At Sahajwallas micro-factory, for example, robots are used to identify and separate useful parts.She says e-waste passes through a sort of production line. We can tailor the DES to be selective to leach certain metals out of an ore, e-waste or other feedstock and the recovery can be selective too.. mining waste urban gold mine electronic In 2020, the company launched a campaign with Belgian telecommunications provider Proximus to persuade people to recycle their old mobile phones; their goal for 2021 is to collect 150,000 disused phones from households in Belgium to be recycled. The precious metals gold, palladium and silver even if present in much smaller quantities, may have a larger monetary value. The Global e-waste Statistics Partnerships Global E-waste Monitor 2020 report noted that the value of raw materials in the global e-waste generated in 2019 is equal to approximately US$57 billion which is higher than the gross domestic product of many countries corresponding to a total of 25Mt. Are Instagram stars facing a brand backlash? Learn more about the steps you can take to make our planet a bit greener. Thanks to e-waste mining, the industry not only has the potential to see immense growth but to find innovative ways to keep our planet sustainable. Tell a gold miner youve got 400g/t of ore, and theyre going to be very excited. The next module involves a special robot to extract useful parts.Another module uses a small furnace to separate the metallic parts into valuable materials, while another one reforms the plastic into a high-grade filament suitable for 3D printing, she says.

is affecting economies, industries and global issues, with our crowdsourced digital platform to deliver impact at scale. In 2002, it began addressing the issue of e-waste, including producing guidelines for environmentally sound e-waste management, building worldwide capacity to better manage e-waste and the prevention of illegal traffic of e-waste to developing countries. The organisers said: We hope that our project of recycling small consumer electronics, and our efforts to contribute to an environmentally-friendly and sustainable society will form part of the legacy of the Tokyo 2020 Games.. Companies and governments could work towards creating a system for closed-loop production in which all old products are collected and then the materials or components re-integrated into new ones. According to the Global e-waste Statistics Partnership, which collects global e-waste statistics, 53.6Mt of e-waste was generated globally in 2019, which is up 21% in five years. Although its a very different industry to mining, its still metals processing.. This figure is projected to grow to 74.7Mt/y by 2030. This is known as a reverse supply chain. Why do some job adverts put women off applying? DES works very well on ores that are amenable to leaching with cyanide, said White. He described DES as being a potential replacement for smelting. Products need to be designed for reuse, durability and eventually safe recycling. A typical iPhone is estimated to house around 0.034g of gold, 0.34g of silver, 0.015g of palladium and less than one-thousandth of a gram of platinum. "They use it for planning purposes, for instance to know the fractions that they currently do not receive in their recycling plants, but also for long term strategy of their business.". Some companies can recover other metals used in electronics, such as indium, selenium, bismuth and other metals present in even smaller amounts. "That is where the focus should be," says Prof Mathews. Daisy can handle nine different models of the phone, separating parts and removing useful components. Its ripe for disruption, Weve flipped the process on its head and developed a low energy, low CAPEX method with no particulate emissions. Last year the number of smartphones grew larger than the number of actual people on this planet, and the number of devices is projected to grow to 25-50 billion by 2020, reflecting lowering costs and rising demand.

"There could also be incentives paid to manufacturers to make their products more easily disassembled.". Theres a whole ecosystem of recyclers who collect these products, and manually or mechanically strip them down into components, said White. Municipal authorities across Japan collected 78,985 tons of electronic devices, while mobile phone operator NTT Docomos shops collected 6.21 million used phones. A lot of recycling capacity needs to come online to deal with that growth. When we spoke in July, White had just returned from a site visit with Argos development partner, the Centre for Process Innovation (CPI) in Teesside, northern England. It is an important raw material, and they are willing to process it in greater quantities in the future. "The discarded-waste devices are first placed into a module to break them down. He provides technical nickel-related education and training internationally for various industries including the chemical, petrochemical, food and beverage, pharmaceutical, water and engineering sectors. In 2020, it was reported that children living close to Umicores Hoboken plant had elevated levels of lead in their blood. Read about our approach to external linking. 2022 BBC. Her "urban mine" at the University of New South Wales (UNSW) is extracting these materials not from rock, but from electronic gadgets. According to a study published in the journal Environmental Science & Technology, the average cathode-ray tube television contains about 450g of copper and 227g of aluminium, as well as around 5.6g of gold.. In many countries, e-waste entrepreneurs and cooperatives of e-waste workers are expanding e-waste recycling operations and experimenting with new and inclusive business models for managing e-waste effectively. We believe the current solutions and methods of recycling are outdated, said White. Urban mining is the production of raw materials such as metals or precious metals from waste and metal scrap. Our process only recycles metals; the whole components will be processed by our recycling partners.. Waste from electronic gadgets can be toxic, yet just 16% of e-waste is recycled, Prof Sahajwalla (right) at her recycling operation with New South Wales environment minister Gabrielle Upton, Thai cave rescue: 'At first it was difficult' Video, Thai cave rescue: 'At first it was difficult', in a joint study from Beijing's Tsinghua University and Macquarie University, in Sydney, The trick that turned seven bags of cocoa into 25. Yes, I would like to receive emails from HOBI International. E-waste is the worlds fastest growing waste stream, said Fred White, commercial manager at Argo Natural Resources. By Emma WoollacottTechnology of Business reporter. Another module uses a small furnace to separate the metallic parts into valuable materials, while another one reforms the plastic into a high-grade filament suitable for 3D printing, she says. She says e-waste passes through a sort of production line. "Another module uses a small furnace to separate the metallic parts into valuable materials, while another one reforms the plastic into a high-grade filament suitable for 3D printing," she says. The Sydney-based expert in materials science believes that her operation will become efficient enough to be making a profit within a couple of years. Many millions of tonnes of televisions, phones and other electronic equipment are discarded each year, despite them being a rich source of metals. Even though the amount of nickel in e-waste is relatively small, the nickel industry is a valuable partner with society in accomplishing the goal of creating a circular economy. At Prof Sahajwalla's micro-factory, for example, robots are used to identify and separate useful parts. Professor Veena Sahajwalla's e-waste factory could be profitable within a couple of years, she says. Shredding of, for example, circuit boards and even whole cellphones into small pieces can help in the separation process.

A system upgrade: a circular electronics system. .chakra .wef-10kdnp0{margin-top:16px;margin-bottom:16px;line-height:1.388;}What is the World Economic Forum doing about the circular economy? While more electronic devices are part of the problem, they also can be a big part of the solution. Over the years, technology has revolutionized our world.

Schwab Foundation for Social Entrepreneurship, Centre for the Fourth Industrial Revolution, Global electronic waste up 21% in five years, and recycling isnt keeping up, These microbes are being used to clean uptoxic electronic waste, Mounting e-waste is harming the planet. Its just a leaching process that can be easily integrated into existing processing circuits.. Some mining companies are already recycling e-waste. In Europe, mining and smelting company Boliden has been recycling waste materials at its Rnnskr smelter in Sweden since the 1960s, and it currently recycles 120,000t/y of electrical material, including circuit boards from computers and mobile phones. How trying to stay cool could make the world even hotter. But it also works very well where cyanide doesnt. That is the staggering amount of new electronic waste that we generate every year. DES consists of non-toxic, environmentally benign and chemically stable ionic liquids that can be used to extract a wide range of metals. .chakra .wef-1yn4l5r{display:block;}@media screen and (min-width:37.5rem){.chakra .wef-1yn4l5r{display:inline;}}@media screen and (min-width:56.5rem){.chakra .wef-1yn4l5r{display:block;}}You can unsubscribe at any time using the link in our emails. Typically, the nickel content may be between 0.5 and 2% of the total weight of a component, far less than its copper and iron content. Thats quite a significant saving on a per-ounce-basis, which is another stepping stone towards a net zero world.. Umicore noted in a statement that it has been testing the blood levels of local children twice a year since 1978, and that there had been multiple years of steady decreases in lead detected, with historically low levels in 2019. While a gold mine can generate five or six grammes of the metal per tonne of raw material, that figure rises to as much as 350g per tonne when the source is discarded electronics. The Basel Convention is a multilateral treaty, effective from 1992, that was designed to reduce the movements of hazardous waste between nations specifically to prevent transfer of hazardous waste from developed to less developed countries. Apple, meanwhile, is trying to counter criticisms that its phones are difficult to recycle with the recent demonstration of a robot called Daisy that can disassemble up to 200 iPhones an hour.Daisy can handle nine different models of the phone, separating parts and removing useful components. Usually, these ores require roasting prior to cyanide treatment, or processes like bio-leaching to unlock that gold.. White said that DES has outperformed cyanide in every test to date. In case youre thinking of running a little electronic gold or silver mines in your room, the small amounts of these minerals in each smartphone should make you think twice. DES also has a low carbon footprint when using standard grid electricity. The next module involves a special robot to extract useful parts. "The mining of e-waste, and production of pure metal ingots from it of copper or gold, promises to be a very profitable business," said Macquarie's Prof John Mathews. "Economic modelling shows the cost of around $500,000 Australian dollars (280,000) for a micro-factory pays off in two to three years, and can generate revenue and create jobs," she says. If we can reduce that CAPEX drastically, well unlock a lot of nickel laterite resources that could then become economic, or at least bankable, projects..

The earliest practitioners are likely to be metals specialists, particularly small entrepreneurial firms who are aware of the scale of the e-waste problem.. Your email address will not be published. The amount of e-waste being generated certainly suggests that the business opportunities for recycling will increase. All these opportunities are likely to make e-waste mining even more profitable in future. The real value for e-miners is in older products, so "it might be more expensive to treat the next generation of electrical items, since they will have less inherent value to recover," says Mr Read.

The earths richest deposits of valuable materials are sitting in landfill sites or peoples homes - maybe even in your drawer. Its not the first time that recycling and sustainability has been highlighted at these events the silver and bronze medals for Rio 2016 were produced using 30% recycled materials but the Tokyo Games went a step further. According to a study published in the journal Environmental Science & Technology, the average cathode-ray tube television contains about 450g of copper and 227g of aluminium, as well as around 5.6g of gold.While a gold mine can generate five or six grammes of the metal per tonne of raw material, that figure rises to as much as 350g per tonne when the source is discarded electronics. Economic modelling shows the cost of around $500,000 Australian dollars for a micro-factory pays off in two to three years, and can generate revenue and create jobs, Sahajwalla comments. Some companies will have a separate recycling line for the various types of batteries, the supply of which for recycling is expected to increase rapidly as electric vehicle batteries come to the end of their life. In a study released last year, Greenpeace calculated that e-waste from smartphone production reached 3.3 million tonnes in 2014. It starts with pre-processing, as e-waste contains a large amount of plastics, ceramics and other non-metallic materials that have a separate path the metallic fraction is what is of prime interest. Professor Veena Sahajwallas conducts urban mining, which is simply defined as the process of reclaiming raw materials from spent products, buildings and waste. This overwhelming flood of screens, cables, chips and motherboards is fuelled by our love of devices, many of which are connected to the internet. Apple, meanwhile, is trying to counter criticisms that its phones are difficult to recycle with the recent demonstration of a robot called Daisy that can disassemble up to 200 iPhones an hour.. With our process, using standard grid electricity, its only 6kg per ounce. Over 53 million tonnes in 2020 alone, according to the Global E-waste Monitor. The figures emerged in a joint study from Beijing's Tsinghua University and Macquarie University, in Sydney, where academics examined data from eight recycling companies in China to work out the cost for extracting these metals from electronic waste. There could also be incentives paid to manufacturers to make their products more easily disassembled.. We see it as a big opportunity. There are different combinations that can be used, said White. This means that not only can DES scale down e-waste processing from larger smelting and refining operations, but it can also reduce the impact of the metals being recycled. There is nickel in the e-waste, although the amount depends on the particular electronic components being recycled. Think of the largest cruise ship. Belgian materials technology company Umicore moved away from traditional metal smelting and changed its entire business model to recycling and reusing metals from e-waste. Mined mainly in China, iridium has been in short supply, with the price rising steadily for months. Then there is the plastic, the glass and the battery. "One of the best policy supports for e-waste will be payment of a deposit to consumers who return their e-products like cell phones to central collection points," he says. DES is a platform chemistry of millions of different combinations of salts and simple organic compounds, White explained.
