ARC-ME: Molecular Stability Engineering for Programmable Plastic Degradation A Conceptual Extension of GCST to Controlled Material Lifecycles
Summary
This conceptual paper proposes a theoretical engineering framework called ARC-ME, in which new plastics would be designed with built-in molecular "off switches" that allow them to degrade rapidly on demand — using triggers like light, temperature, pH, or enzymes — rather than persisting in the environment for centuries. The idea reframes plastic pollution as a materials design problem rather than just a waste management challenge. While speculative, the framework offers a forward-looking vision for preventing microplastic formation at the source by making plastics that can be reliably deactivated after use.
Abstract Conventional plastics are designed for maximal chemical stability, resulting in persistence times of hundreds to thousands of years in natural environments. From the perspective of Global Complexity Stability Theory (GCST), this corresponds to a near-zero natural decay coefficient, creating a long-lived metastable state that accumulates as environmental debt. The ARC-ME framework proposes the opposite engineering paradigm: materials with deliberately embedded, triggerable instability pathways. Instead of passive longevity, the material lifecycle becomes programmable — stable during use, but capable of rapid, controlled degradation when externally activated. The approach reframes plastic pollution not as an inevitable waste-management problem, but as a stability-design challenge: create polymers whose structural integrity can be intentionally collapsed under safe, selective conditions (light, temperature, pH, enzymes, redox signals), converting persistent macromolecules into biodegradable fragments or mineralizable monomers. This conceptual shift integrates cleavable molecular units, designer enzymes, aggregation chemistry for microplastics, and GCST-derived stability thresholds to enable materials that actively participate in circular flows rather than resist them.
