Circular Economy Approaches to Critical Minerals – Detailed Explanation With Case Laws

1. Introduction

Circular economy approaches to critical minerals refer to legal, economic and technological methods for keeping important minerals in use for as long as possible instead of following the traditional model of extract → use → discard.

Critical minerals such as lithium, cobalt, nickel, manganese, graphite, copper and rare earth elements are increasingly important for batteries, electric vehicles, renewable-energy equipment, electricity networks, electronics and energy-storage systems.

The energy transition can therefore create a paradox. Renewable-energy technologies reduce fossil-fuel dependence, but their production can increase demand for particular minerals. A circular economy seeks to reduce this pressure through recycling, reuse, repair, recovery, urban mining and efficient product design.

2. Main Circular-Economy Approaches

A. Recycling

Recycling allows valuable minerals to be recovered from products after their useful life.

For example, lithium-ion batteries can potentially provide secondary sources of:

lithium;

cobalt;

nickel;

manganese; and

copper.

A strong legal framework can require manufacturers and importers to establish collection and recycling systems.

B. Reuse and Repurposing

A product does not always have to be immediately recycled when its original function ends.

For example, an electric-vehicle battery that is no longer suitable for vehicle use may still be suitable for stationary electricity storage.

This creates a second life before final recycling.

C. Urban Mining

Urban mining means recovering minerals from existing products, buildings, electronic waste and infrastructure.

Old electrical equipment, batteries, telecommunications equipment and electronic devices can become secondary mineral resources.

This reduces dependence on new extraction.

3. Product Design

Circular economy regulation begins before a mineral-containing product enters the market.

Law can encourage manufacturers to design products that are:

durable;

repairable;

recyclable;

modular;

easy to disassemble; and

traceable.

For batteries, digital information about composition, origin and previous use can make recycling easier.

The European Union's Critical Raw Materials Act is an important international example because it combines primary supply, recycling and resource efficiency in its critical-raw-material strategy.

4. Extended Producer Responsibility

Extended Producer Responsibility (EPR) places some responsibility on producers for products after consumers have finished using them.

Under an EPR approach, manufacturers may be required to:

collect waste products;

finance recycling;

meet recovery targets;

provide information about materials;

establish take-back systems; and

report recycling performance.

This changes the economic structure of mineral use.

Instead of treating waste as someone else's problem, the producer has an incentive to design products that are easier and cheaper to recover.

5. Critical Minerals and South African Law

South Africa has significant mineral resources and an important mining sector. The Mineral and Petroleum Resources Development Act 28 of 2002 (MPRDA) provides the principal framework for mineral-resource development.

However, circular economy approaches require more than mining regulation. They also involve:

environmental law;

waste law;

industrial policy;

competition law;

energy law;

product regulation; and

climate policy.

The National Environmental Management: Waste Act 59 of 2008 is particularly relevant because end-of-life batteries, electronic equipment and mineral-containing industrial waste may require regulated waste-management approaches.

The Climate Change Act 22 of 2024 also provides a broader transition framework toward a low-carbon and climate-resilient economy.

6. Environmental Protection

Circular mineral systems can reduce pressure on new mining, but recycling itself can create environmental risks.

Battery recycling, for example, may involve hazardous substances and require proper treatment facilities.

Therefore, circular-economy law must address:

pollution;

hazardous waste;

water use;

emissions;

worker safety;

transportation of waste;

disposal of non-recoverable materials; and

environmental rehabilitation.

Circularity should therefore not mean simply moving environmental risks from mining sites to recycling facilities.

7. Important Case Laws

Maccsand (Pty) Ltd v City of Cape Town 2012 (4) SA 181 (CC)

The Constitutional Court demonstrated that obtaining one regulatory approval does not necessarily remove the requirement to comply with another regulatory system.

This principle is highly relevant to critical-mineral circularity.

A company recovering minerals from batteries or electronic waste may need to comply with several legal regimes. A waste-management authorisation, for example, cannot automatically replace environmental or other required approvals.

Fuel Retailers Association of Southern Africa v Director-General: Environmental Management, Mpumalanga 2007 (6) SA 4 (CC)

The Constitutional Court emphasised sustainable development and the need to consider environmental, social and economic factors together.

This principle strongly supports circular approaches to minerals because policymakers must consider both:

resource security + environmental protection + economic development.

MEC: Department of Agriculture, Conservation and Environment v HTF Developers 2008 (2) SA 319 (CC)

The case reinforced the importance of environmental protection within South Africa's constitutional and statutory framework.

For critical minerals, this supports an approach where mineral recovery and industrial development must remain compatible with environmental-management principles.

Minister of Environmental Affairs v ArcelorMittal South Africa Ltd [2020] ZASCA 40

The Supreme Court of Appeal dealt with environmental regulation in an industrial context.

Although not specifically a critical-minerals recycling case, it demonstrates the importance of complying with environmental regulatory requirements when industrial activities generate environmental impacts.

It is therefore a useful analogical authority for circular mineral-processing facilities.

8. Circularity and Competition

Critical minerals can become concentrated in particular companies or countries. Recycling can create new secondary supply, potentially reducing dependence on a limited number of primary suppliers.

However, competition law must also prevent dominant firms from controlling recycling networks in ways that exclude competitors.

Rules may therefore be required concerning:

access to used batteries;

collection networks;

recycling facilities;

mineral-processing technology;

data about battery composition; and

secondary-mineral markets.

9. Economic and Social Benefits

A circular critical-mineral system can create several benefits.

Resource security

Recycling provides an additional source of minerals when primary supply is constrained.

Lower environmental pressure

Greater recovery can reduce the need for some new extraction.

Industrial development

Recycling and mineral processing can create domestic manufacturing industries.

Employment

Collection, repair, refurbishment and recycling can create new jobs.

Energy-transition resilience

Reliable access to lithium, nickel, cobalt, copper and other minerals is important for batteries, grids and renewable-energy technologies.

10. Challenges

Circularity cannot completely replace mining.

Minerals are lost during manufacturing and recycling, and demand for clean-energy technologies may grow faster than secondary supply.

There are also problems involving:

high recycling costs;

insufficient collection systems;

technological limitations;

illegal waste trading;

weak traceability;

hazardous materials;

intellectual-property barriers; and

inadequate infrastructure.

Consequently, the most realistic legal approach is a combined primary-and-secondary mineral strategy.

11. Conclusion

Circular economy approaches to critical minerals seek to transform mineral governance from a linear model of extraction and disposal into a system based on reuse, repair, recovery, recycling and resource efficiency.

For South Africa, the approach can operate through the combined framework of the MPRDA, National Environmental Management Act, Waste Act, Climate Change Act and related industrial and energy legislation.

The cases Maccsand, Fuel Retailers, HTF Developers and ArcelorMittal are mainly analogical authorities, because South African courts have not yet developed a detailed doctrine specifically called “circular economy approaches to critical minerals.”

The central legal idea is that critical minerals should increasingly be treated as strategic resources that remain within the economic system, rather than materials whose value ends when the original product is discarded. A strong circular framework can therefore support resource security, environmental protection, industrial development and the long-term energy transition.
