Traditional forms of mining are inherently unsustainable: It’s an energy-intensive process that depletes resources, destroys ecosystems, pollutes water systems, generates enormous amounts of waste, and often harms local communities. However, mining is also an essential industry that provides the raw materials for nearly every facet of modern life—from technology and infrastructure to energy and food production and economic growth. Therefore, it is essential to mitigate its negative impacts and find the balance between what is needed to thrive while safeguarding resources for future generations to do the same. Which begs the question: Is sustainable mining possible?

The mining industry challenge: balancing supply and demand with sustainability and ethics

The harmful impacts of mining are indisputable. A report published by the Responsible Mining Foundation which studied the economic, environmental, social, and governance (EESG) impacts associated with a sample of 38 large mining companies (collectively covering 18 home countries, 55 producing companies, and approximately 1,000 mining sites worldwide) uncovered over 260 reports of wide-scale incidents with harmful impacts. Some of these included:

• Death of miners due to poor or non-existent safety regulations
• Drinking water contamination
• Pollution (air, soil, water)
• Loss of livelihoods
• Human rights violations, including forced labour
• Habitat loss and land degradation
• Forced displacement of local populations
• Toxic spills causing death and injury to people, fauna and flora
• Occupational diseases

Operational practices of mining companies aside, the industry as a whole is operating under challenging – and somewhat unprecedented – times:

1. Climate, social, and environmental pressures on the mining industry to decarbonise operations, reduce the impact on ecosystems, ensure local communities are treated fairly, improve workers’ health and safety, safeguard scarce resources, and demonstrate a quantifiable contribution to a sustainable future.
2. Resource depletion. Mining, by nature, involves extracting non-renewable resources. Once these finite resources are depleted, they cannot be regenerated, making it difficult to claim that mining is genuinely sustainable in the long term.
3. Geopolitical instability (e.g. war, political instability and civil disruption, pandemics) leads to supply chain disruption, price volatility, trade tensions, embargoes, resource nationalism, etc.
4. Labour and skills shortages due to travel restrictions and an industry perceived as unattractive make it challenging to attract and retain new talent – leading to a loss in productivity.
5. Demand insecurity caused by new technologies/materials that can replace mined resources, thus reducing the need for traditional minerals or metals. For example, aluminium is increasingly being substituted by carbon fibre or advanced composites in automotive manufacturing, decreasing demand for bauxite mining.
6. Energy-intensive operations. Despite the push for renewable energy, mining activities’ emissions contribute to climate change and can offset the sustainability benefits of the extracted materials.

Harmful impacts and challenges aside, the global demand for minerals, metals, and rare earth elements continues to rise, driven by the needs of industries like renewable energy, electric vehicles, and high-tech manufacturing. As countries strive to meet their development goals, the pressure to balance resource demand with environmental and social responsibility has never been more significant.

Technologies & approaches creating a pathway to sustainable mining

The extraction of finite resources and the environmental costs imply that the mining industry can never be ‘sustainable’ in the traditional sense. However, various approaches and technologies can make it more environmentally and socially responsible – thus significantly contributing to overall global sustainability goals.

1. Integrating IoT in Smart Mining

The Internet of Things (IoT) refers to a network of connected devices communicating and exchanging data in real time, enabling automated and intelligent decision-making. In smart mining, IoT is a cornerstone technology that improves operational efficiency, enhances safety, and minimises environmental impact by allowing real-time monitoring, predictive maintenance, and optimised resource management throughout the mining process.

For example, Rio Tinto’s Mine of the Future in Western Australia uses IoT-enabled autonomous trucks, drills, and trains at its iron ore mines.

2. Building a Circular Economy

A circular economy is an economic model that minimises waste and maximises resource efficiency by reusing, recycling, and repurposing materials throughout their lifecycle. Instead of the traditional “take-make-dispose” approach, the circular economy emphasises keeping resources in use for as long as possible, reducing environmental impact.

Mining companies can contribute to a circular economy by focusing on green tech solutions, recycling materials to reduce the need for raw material extraction, repurposing waste and reusing it in construction or infrastructure, and building closed-loop systems that ensure mined materials are fully utilised and returned to the supply chain. Leading by example is Umicore, a global materials technology company that recovers and recycles precious and rare metals from used batteries, electronics, and catalysts. This reduces the need for new mining, promotes sustainability, and supports the growing demand for critical metals in the renewable energy and electric vehicle sectors.

3. Shifting to Renewable Energy in Mining

Shifting from fossil fuels to renewable energy sources, such as solar and wind power, can significantly reduce the carbon footprint of mining operations. Some mines are already integrating renewables into their energy mix to power equipment and facilities and making a strong effort to future-proof harmful impacts that they might have:

• Environmental Reclamation: Efforts to restore and rehabilitate mining sites post-extraction can help reduce long-term ecological damage. This includes replanting vegetation, restoring water systems, and creating new ecosystems where possible. For example, reclamation efforts by Teck Resources’ Highland Valley Copper Mine in British Columbia, Canada, have resulted in once-mined areas becoming home to thriving, biodiverse ecosystems that have effectively reduced the mine’s long-term environmental impact.
• Ethical and Transparent Practices: Initiatives like fair trade mining and transparency in supply chains ensure that mining operations respect human rights, labour laws, and environmental regulations. Consumers and businesses increasingly demand ethically sourced materials.

While ‘sustainable mining’ seems inherently contradictory,  advancements in technology, responsible practices, and a commitment to reducing harm can make mining more sustainable. Rather than an end goal, sustainable mining is a step in the right direction and will require continuous innovation, adaptability, and responsibility.
