Urban mining addresses the critical problem of resource scarcity and waste management in rapidly growing cities. As urban areas expand, the demand for raw materials increases, leading to environmental degradation and depletion of natural resources. Simultaneously, cities generate vast amounts of waste, including electronic waste (e-waste), construction debris, and discarded consumer goods, which pose significant disposal challenges. Urban mining offers a sustainable solution by recovering valuable materials from this urban waste, thereby reducing the need for virgin resources and minimising environmental impact.
At its core, urban mining is about redefining waste as a resource, playing a crucial role in creating a circular economy where materials are continuously reused, reducing the strain on natural resources and lowering carbon emissions. The process utilises sophisticated recycling technologies to recover materials that can be reused in the production cycle, reducing the need for virgin materials and minimising environmental impact. Approaches such as electronic waste (e-waste) recycling, material recovery facilities, and advanced sorting technologies play a pivotal role.
These methods enable the efficient separation and purification of materials, ensuring they meet industry standards for reuse. For example, urban mining can reclaim gold, silver, copper, and palladium from discarded electronic devices, offering a more sustainable and often cheaper alternative to traditional mining practices. Additionally, repurposing construction materials helps reduce the demand for new resources and decreases the volume of waste sent to landfills.
Furthermore, urban mining fosters economic growth by creating new industries and job opportunities. As cities adopt more sustainable practices, the demand for expertise in waste management and material recovery will increase, driving innovation and investment in green technologies. This shift towards sustainability not only benefits the environment but also enhances the quality of life for urban residents by promoting cleaner, healthier cities.

Inclusive Urban Mining: An Opportunity for Engineering Educationmdpi.com
With the understanding that the mining industry is an important and necessary part of the production chain, we argue that the future of mining must be sustainable and responsible when responding to the increasing material demands of the current and next generations. In this paper, we illustrate how concepts, such as inclusiveness and the circular economy, can come together in new forms of mining—what we call inclusive urban mining—that could be beneficial for not only the mining industry, but for the environmental and social justice efforts as well. Based on case studies in the construction and demolition waste and WEEE (or e-waste) sectors in Colombia and Argentina, we demonstrate that inclusive urban mining could present an opportunity to benefit society across multiple echelons, including empowering vulnerable communities and decreasing environmental degradation associated with extractive mining and improper waste management. Then, recognizing that most engineering curricula in this field do not include urban mining, especially from a community-based perspective, we show examples of the integration of this form of mining in engineering education in first-, third- and fourth-year design courses. We conclude by providing recommendations on how to make inclusive urban mining visible and relevant to engineering education.

Mining the Built Environment: Telling the Story of Urban Miningmdpi.com
Materials are continuously accumulating in the human-built environment since massive amounts of materials are required for building, developing, and maintaining cities. At the end of their life cycles, these materials are considered valuable sources of secondary materials. The increasing construction and demolition waste released from aging stock each year make up the heaviest, most voluminous waste outflow, presenting challenges and opportunities. These material stocks should be utilized and exploited since the reuse and recycling of construction materials would positively impact the natural environment and resource efficiency, leading to sustainable cities within a grander scheme of a circular economy. The exploitation of material stock is known as urban mining. In order to make these materials accessible for future mining, material quantities need to be estimated and extrapolated to regional levels. This demanding task requires a vast knowledge of the existing building stock, which can only be obtained through labor-intensive, time-consuming methodologies or new technologies, such as building information modeling (BIM), geographic information systems (GISs), artificial intelligence (AI), and machine learning. This review paper gives a general overview of the literature body and tracks the evolution of this research field.

Urban Mining in Ubiquitous Cities of Goldourworld.unu.edu
The origin of the resources used to fuel modern society is an increasingly hot topic in many fora. Earlier this year, the world watched transfixed as 33 Chilean miners were pulled from the bowels of the Earth after being trapped for 69 days when the mine collapsed. The happy ending and feeling of relief gave way to a warm feeling of awe at the indomitable human spirit, similar to that the global public gets from moon landings and the like.

Toward circular and socially just urban mining in global societies and cities: Present state and future perspectivesfrontiersin.org
This study evaluates the perspectives of urban mining in the framework of the circular economy (CE) and starts with a brief analysis of the size of global and urban metabolism and the role that plays materials and waste streams such as construction and demolition waste (C&DW) and waste from electronic and electrical equipment (WEEE). These can be considered as temporary stocks or deposits to be mined in the future, thus shedding light on the concept of recycling potential, end-of-life functional recycling, and material concentration. The recycling potential could be very variable as in the case of metals. The average concentration of some metals (e.g., gold) in WEEE shows that it is higher per ton of electronic product compared to the amount in mining ores. This explains the importance of the concept of urban mining in the circular economy (CE) transition, given that the CE concept was born to address the challenges of high resources consumption rates and worsening environmental problems. The urban mining phenomenon becomes timely and extremely important for cities as they are relevant hubs of materials and energy consumption and source of environmental and social impacts in external areas due to mining and extraction activities. This study points to the need for creating and establishing strong synergies between the concept of CE and urban mining and the role of cities as innovators in finding circular solutions by incorporating more socially just urban mining activities to improve urban resource management, land use, and local and global wellbeing.

A comprehensive review of urban mining and the value recovery from e-waste materialssciencedirect.com
E-waste is the source of both hazardous materials and valuable secondary resources. The challenge is to identify the potential for recovering value from this waste stream for different supply chains when there are diverse definitions in the field. The urban mining approach employs recycling and circular solutions inspired by principles such as industrial metabolism, industrial ecology, and the circular economy. This study presents a systematic review of peer-reviewed literature on urban mining and a comprehensive analysis of the many definitions of value recovery. This includes the stages of e-waste urban mining, the value recovery potential according to circular economy principles, location, and critical raw materials (CRMs). The results suggest that the exploitation of anthropogenic urban mines depends on Waste-to-Resources (WtR) and Waste-to-Energy (WtE) ratios, and the techniques borrowed from conventional mining. We highlight the importance of e-waste as a secondary source of CRMs (e.g., Au, Ag, Cu, Li, and Co), and provide recommendations regarding the critical analysis of the potential of urban mining to mitigate the impact of e-waste through circular processes and value recovery. Innovation is needed to promote a sustainable circular economy, and a harmonized regulatory framework relating to social aspects and technical potential.
