Designing circular, low-impact materials could decouple tech growth from critical mineral scarcity, BAM study argues

Indigenous frameworks such as the Māori principle of *kaitiakitanga* (guardianship) and the Quechua concept of *ayni* (reciprocal exchange) reframe minerals as part of living systems requiring stewardship, not extraction. These traditions prioritize closed-loop material cycles and intergenerational equity, contrasting with the BAM’s techno-optimist approach that assumes perpetual growth in material throughput. Incorporating these perspectives could shift design goals from performance metrics to relational metrics—how materials sustain communities and ecosystems over centuries.

Historical precedents like the 1970s oil shocks demonstrate that material substitution (e.g., plastics for metals) can reduce dependency but often externalize new harms, such as microplastic pollution and petrochemical waste. The post-WWII era’s rare earth boom in Congo under Belgian colonial rule reveals how 'critical minerals' become geopolitical tools, with extraction-driven economies collapsing when prices crash. The BAM’s focus on design innovation echoes 1980s eco-efficiency movements, which promised dematerialization but delivered rebound effects—more efficient use leading to more consumption.

Cross-cultural comparisons show that societies with strong communal repair cultures (e.g., India’s *kabadiwalas*, Ghana’s *scrap dealers*) achieve higher material recovery rates than industrialized nations, despite lacking formal recycling infrastructure. Inuit knowledge of adapting to resource scarcity through modular, repairable tools offers a blueprint for designing batteries and turbines for disassembly and reuse in extreme environments. These traditions highlight that circularity is not a technological challenge but a cultural and organizational one, requiring collective governance models.

Scientific literature confirms that material substitution and design-for-disassembly can reduce critical mineral demand by 30–50% in energy technologies, but these gains are often offset by growth in device numbers—a Jevons paradox effect. Life-cycle assessments show that recycling rates for rare earths and lithium hover below 5% globally, with most losses occurring in early processing stages due to inefficient separation technologies. The BAM’s emphasis on 'high-performance materials' aligns with industrial priorities but risks neglecting low-tech, high-durability alternatives that perform adequately for decades.

Artistic traditions like Japanese *wabi-sabi* (beauty in imperfection and transience) and Scandinavian *hygge* (coziness through sufficiency) challenge the fetishization of new, high-performance materials. Indigenous art forms such as Navajo sandpainting or Aboriginal dot art encode ecological knowledge in material form, suggesting that design can encode relational values rather than extractive ones. These perspectives frame material durability not as a technical constraint but as a spiritual and aesthetic commitment to future generations.

Scenario modelling by the International Resource Panel suggests that without radical material efficiency, global demand for critical minerals could triple by 2050, outpacing even optimistic recycling and substitution rates. Future-proof designs must prioritize modularity, standardized interfaces, and 'design for disassembly' to enable circular flows, but these require policy mandates and economic incentives that currently favor linear models. The BAM’s approach risks locking in high-risk mineral chains if it does not address the rebound effects of efficiency gains.

Marginalized voices—artisanal miners in Congo, Indigenous land defenders in the Amazon, and waste pickers in India—are systematically excluded from material innovation discourses despite bearing the brunt of extraction’s harms. Their knowledge of low-impact extraction, local repair networks, and community-based recycling could inform scalable alternatives to industrial solutions. The BAM’s perspective, while technically rigorous, reflects a top-down innovation model that sidelines grassroots expertise in favor of corporate R&D priorities.

The trickster here is Hermes, the Greek god of boundaries and exchange, who exposes the absurdity of designing 'robust' materials to sustain an inherently fragile linear economy. Hermes would point out that the BAM’s 'solution' is like designing a stronger chain to hold a sinking ship—ignoring the fact that the ship itself is the problem. The trickster also reveals how 'critical minerals' are a moving target: what is 'critical' today (e.g., lithium) may become obsolete tomorrow, but the extraction apparatus remains. By inverting the narrative—asking who benefits from mineral dependency—Hermes clarifies that the real risk is not scarcity but the power structures that profit from it.
