Chewing gum’s primary component, synthetic rubber, is not biodegradable. This resistance to natural breakdown means that discarded gum persists in the environment for a significant duration. The longevity of chewing gum as waste is a direct consequence of its synthetic makeup, designed for durability and chewability, not for decomposition.
The persistent nature of discarded gum contributes to urban blight, necessitating costly removal efforts by municipalities. Beyond aesthetics, the accumulation of this waste can pose risks to wildlife, which may ingest it, and contributes to microplastic pollution as it slowly fragments over time. Awareness of the material’s non-biodegradable properties is essential for promoting responsible disposal practices.
