Which material is considered non-biodegradable?

Non-biodegradable materials are those that do not break down naturally in the environment or do so very slowly. Plastic is a prime example of a non-biodegradable material because it can take hundreds to thousands of years to decompose. This longevity in the environment contributes to pollution and environmental damage, as plastic waste can accumulate in landfills, oceans, and other ecosystems, posing threats to wildlife and human health.

In contrast, materials like paper, glass, and food waste are generally considered biodegradable. Paper decomposes relatively quickly when exposed to moisture and microorganisms. Glass, while not biodegradable, can be recycled infinitely without losing quality, which makes it a more sustainable option compared to plastic. Food waste is organic and can decompose naturally, contributing to nutrient cycles in soil when composted.
