Imperial College start-ups are leading the way in solving critical environmental problems through innovative solutions. From construction materials made from food waste, to sustainable fashion apps and fixing broken items, these students and staff are using their entrepreneurial spirit to tackle the climate crisis.

Repair Cafés match people who need stuff fixed with people who like fixing things, reducing waste and emissions by extending the life of items. But manufacturers have made it harder to repair items, denying us the right to repair and contributing to the fastest-growing waste stream in the world. The Right to Repair is a growing global movement advocating for people to repair their own electronic devices without being hindered by restrictive policies and practices of manufacturers.

Have you ever thought about what happens to your old electronic devices when you replace them with new ones? E-waste, also known as electronic waste, refers to discarded electronic devices, such as smartphones, computers, televisions, and other electronic gadgets. This type of waste is becoming a significant global problem, as it contains hazardous materials and is difficult to recycle. According to a report by the United Nations, the world generates around 50 million tons of e-waste every year, with only a small fraction of it being recycled properly. This not only causes harm to the environment but also means that valuable resources, such as precious metals, are being wasted. Enter the concept of "cash for e-waste." This idea aims to incentivize people to properly dispose of their e-waste by paying them for it. This approach has been studied and advocated by leading academics in the field, such as Dr. Kate Armitage and Professor Eric Williams, who argue that it could be a crucial step towards a more sustainable future. By properly recycling e-waste, not only are we reducing harm to the environment but also recovering valuable materials. For example, a single computer can contain up to several grams of gold, which can be recovered and sold. This not only helps to reduce the environmental impact of e-waste but also creates economic opportunities, particularly in developing countries where e-waste is often exported. E-waste is a complex and pressing issue, but by exploring it and learning more, you can help make a difference. Who knows, you might even uncover some hidden treasures in the process!

Mining has been a crucial part of human civilization for centuries, providing us with the resources we need to build, create and thrive. But with this extraction comes consequences, particularly in the form of mine tailings. Mine tailings are the waste materials left over after the ore has been extracted, and they can have significant impacts on the environment, particularly with regards to climate change. To understand the impact of mine tailings, it's important to first understand the science behind mining. When ore is extracted, the minerals are separated from the rest of the material, leaving behind a mixture of minerals, water, and other substances. This mixture is called tailings, and it can contain harmful chemicals, such as heavy metals, that can leach into the environment. Leading academics in the field, such as Dr. Sara Colombo and Dr. Jian Kang, have studied the environmental impact of mine tailings and have found that they can lead to soil and water pollution, as well as contribute to greenhouse gas emissions. For example, Dr. Colombo's research has shown that tailings dams can release large amounts of methane, a potent greenhouse gas, into the atmosphere. These impacts are a concern for many communities, as well as for the planet as a whole. But despite this, there is hope for a more sustainable future. Researchers like Dr. Jian Kang are working to develop new technologies that can reduce the environmental impact of mine tailings, such as using them as a source of energy instead of just waste.

Traditional diamond mining is a billion-dollar industry with significant environmental impact, releasing large amounts of carbon emissions and causing damage to local ecosystems worldwide. However, carbon-negative diamonds are produced through a process that actually captures carbon emissions from the atmosphere, making them a much more sustainable alternative for the jewellery industry.  Aether Diamonds, a major player in this industry, uses direct-capture technology for diamond production in a two-step process. First, a reactor is used to extract the carbon dioxide from the atmosphere, while this raw carbon material is placed in another reactor that kickstarts the diamond-growing process. The resulting diamonds are visually indistinguishable from traditionally-mined diamonds and have the same physical and chemical properties, but have been produced with a much lower carbon footprint.  This ingenious solution reimagines existing carbon-capture services, where firms are paid by various multinational corporations to capture their carbon emissions, by recycling this extracted carbon dioxide for an inventive purpose. By eliminating 20 tons of carbon dioxide for every 1-carat diamond produced, each diamond can actively contribute to carbon emission reduction efforts.  Beyond the jewelry industry, researchers have used a similar process to produce important industrial materials from carbon. Dr. Stuart Licht, a chemistry professor at George Washington University, is a leading academic in this field of renewable technology. His patented technology, the Solar Thermal Electrochemical Photo (STEP) energy conversion, captures carbon dioxide using renewable solar energy to create carbon nanofibers. This material provides a lighter and stronger alternative to metals like steel, and is used in luxury sports cars, aeroplanes like the Boeing Dreamliner, and high-end athletic equipment. These creative uses of carbon-capture technology offer a promising future, especially with carbon-negative diamonds for the sustainable fashion industry. Beyond that, these diamonds also offer a more ethical alternative — sustainable diamond production avoids the international human rights abuses and violence that traditional diamond mining has been linked to.  All in all, carbon-negative diamonds have the potential to revolutionize the sustainable fashion industry and beyond, and are a fascinating scientific innovation with many exciting future implications.

Water security is a pressing issue in our world today, as access to clean and safe water is essential for human survival, yet many communities face challenges in securing a reliable source of water. That's why it's important to explore the innovative solutions being developed to ensure the long-term sustainability of our water supplies. Did you know that only 0.5% of the world's water is fresh and accessible, while the rest is either too salty or too remote to use? This is why it's crucial to conserve water and ensure that we have access to it for future generations. Leading academics in the field of water security, such as Dr. Jay Famiglietti and Dr. Arjen Hoekstra, have conducted extensive research on water conservation and developed innovative solutions to the challenges faced by communities in securing water. Dr. Famiglietti, a hydrologist and professor at the University of Saskatchewan, has developed new methods for measuring groundwater depletion, which is a critical issue in many parts of the world. Meanwhile, Dr. Hoekstra, a former water expert and professor at the University of Twente in the Netherlands, has focused on the development of the "Water Footprint" concept, which measures the amount of water used to produce goods and services. Here are some interesting facts about water security and conservation: - In countries like the United States, the amount of water used by households has increased by over 600% in the last 50 years. - In some regions, such as the Middle East, the demand for water is growing at an unsustainable rate, putting pressure on already limited resources. - The agriculture sector uses 70% of the world's freshwater resources, making it the largest user of water. By exploring water security and innovations in water conservation, you can help to ensure that this precious resource is protected for future generations. Get started today and make a difference!
