Natural rubber latex foam (NRLF) cushions have been developed as a sustainable alternative to plastic-based cushioning for fresh produce. To support circular economy strategies, this study investigates NRLF degradation under two post-consumer scenarios: (1) soil burial and (2) sunlight exposure. Results show that UV from sunlight significantly accelerates degradation—over 60% of mechanical strength is lost within 7 days, and 35% of foam cell walls collapse, reducing cushioning efficiency. In contrast, soil burial under moist conditions leads to gradual biodegradation within 24 weeks, even without UV exposure. These findings suggest that NRLF does not persist in the environment like plastic-based foams. To enhance sustainability, this study proposes a reuse strategy where NRLF cushions are collected and reused before final disposal. This approach could extend product life, reduce environmental burden, and align with circular economy goals. Understanding NRLF’s degradation mechanisms under different disposal scenarios.
