Nuclear waste as resource: systemic shift in radiopharmaceutical production to address isotope shortages and circular economy gaps

Indigenous epistemologies frame radioactive waste not as inert material to be repurposed but as entities with agency and relational obligations, challenging the extractivist logic of 'making drugs from waste.' Navajo and Māori communities, who bear disproportionate burdens from uranium mining legacies, have articulated principles of consent and reciprocity that are absent in corporate-led repurposing schemes. Their knowledge systems caution against technological fixes that externalise costs onto future generations and sacred landscapes.

The medical isotope crisis traces back to the 1940s Manhattan Project, when reactor designs prioritised plutonium production over medical isotope yields, embedding a structural bias in nuclear infrastructure. The collapse of the Chalk River reactor in 2007 exposed the fragility of a supply chain dependent on a handful of aging reactors, yet policymakers have repeatedly deferred diversification in favor of incremental fixes. Historical case studies, such as the Soviet-era production of molybdenum-99 from weapons-grade uranium, reveal how geopolitical imperatives shape medical isotope availability.

In Japan, the concept of 'mottainai'—a Buddhist ethic of avoiding waste—has inspired community-led initiatives to repurpose low-level radioactive materials in art and architecture, offering a cultural counterpoint to industrial extraction. West African traditions of 'sankofa'—learning from the past to inform the future—align with circular economy principles, suggesting that local knowledge can guide sustainable isotope production. Inuit communities in Canada have developed monitoring protocols for environmental radioactivity that integrate Indigenous and Western science, demonstrating hybrid approaches to nuclear governance.

The scientific literature confirms that certain isotopes (e.g., lutetium-177, actinium-225) can be extracted from spent nuclear fuel with yields dependent on reactor type and cooling time, but current methods face challenges in purity, scalability, and regulatory approval. Emerging accelerator-based production methods, such as those using cyclotrons, offer lower-waste alternatives but require significant infrastructure investment. The International Atomic Energy Agency’s safety standards for medical isotope production remain unevenly implemented, particularly in low-resource settings.

Artists like Ken + Julia Yonetani have used radioactive salts in installations to critique the aestheticisation of nuclear harm, revealing how beauty can obscure ethical erasures in waste repurposing. In Tibetan Buddhist traditions, mandalas constructed from colored sands—including mineral pigments—embody impermanence and interdependence, offering a spiritual framework for confronting the transience of nuclear materials. The Japanese art form of 'kintsugi'—repairing broken pottery with gold—challenges linear notions of waste, suggesting that radioactivity might be reimagined as a medium for renewal rather than ruin.

Scenario modelling by the OECD’s Nuclear Energy Agency projects a 40% shortfall in medical isotopes by 2035 under current trends, with climate change exacerbating reactor shutdowns due to water scarcity. Alternative futures include decentralised micro-reactors co-located with hospitals, blockchain-enabled supply chains for isotope tracking, and AI-driven waste characterisation to optimise extraction. The most resilient pathways integrate equity metrics, ensuring that Global South communities are not treated as sacrifice zones for Global North medical demand.

Frontline communities in Niger, Kazakhstan, and the Navajo Nation—who have borne the brunt of uranium mining—have long demanded a seat at the table in isotope governance, yet their voices are systematically excluded from policy dialogues. Women in rural areas, who often bear caregiving burdens, are disproportionately affected by isotope shortages due to limited access to advanced diagnostics, yet their perspectives are absent in cost-benefit analyses. Grassroots organisations like the Indigenous-led Nuclear Free Future Coalition argue that 'waste repurposing' without consent constitutes a form of environmental racism.

The trickster figure Hermes—messenger of the gods and patron of thieves—laughs at the absurdity of classifying nuclear waste as a 'resource' while communities downstream remain poisoned, exposing the double standards in circular economy rhetoric. Anansi, the West African trickster-spider, would weave a web of red tape around corporate schemes to repurpose waste, forcing them to confront their own contradictions. Erasmus’ 'Praise of Folly' satirises the hubris of technocrats who believe they can 'tame' radioactivity through extraction, ignoring the chaos it leaves in its wake.
