Urban Mining

This solution addresses the problem of reliance on finite energy sources like batteries and external power supplies. The aim is to capture ambient energy from sources such as solar radiation, thermal gradients, vibrations, and radiofrequency waves, converting them into usable electrical power. Doing so enables devices to operate autonomously, often for their entire lifespan, without the need for external power or frequent battery replacements. By integrating energy harvesting devices into urban infrastructure, cities can power smart sensors, public lighting, and transportation systems, enhancing sustainability and resilience.

This energy storage solution addresses critical issues related to energy waste, resource scarcity, and environmental degradation. Unlike traditional batteries that often end up in landfills, circular batteries are engineered for reuse, refurbishment, and recycling, creating a closed-loop lifecycle that significantly reduces electronic waste and the need for raw materials. These batteries store electricity from various sources, including renewable energy, and upon reaching the end of their lifecycle, they are disassembled, and valuable components are recovered and reused.

This solution addresses urban issues such as food insecurity, environmental degradation, and urban heat islands. This approach encompasses a variety of techniques, including vertical farming, underground farming, hydroponics, and rooftop gardens, to cultivate food within city landscapes. By bringing food production closer to urban consumers, urban agriculture reduces the dependency on long supply chains, enhances food security, and minimises the carbon footprint associated with transporting food over long distances.

This solution addresses inefficient urban waste management, which often leads to increased landfill use, pollution, and high operational costs. This technology leverages advanced image recognition and artificial intelligence to accurately identify and sort recyclable materials from waste streams. By automating the sorting process, these systems reduce contamination, enhance recycling rates, and lower the dependency on manual labour.

These systems treat wastewater locally, near its source, thus eliminating the need for large-scale sewer networks and central treatment plants. By using technologies such as constructed wetlands, anaerobic baffled reactors, and biogas reactors, DWT systems effectively reduce pollution, recover valuable resources, and enable the reuse of treated water. This approach not only mitigates environmental impacts but also enhances public health and supports sustainable urban development.
