What does biodegradable mean?

In IB Environmental Systems & Societies (ESS), biodegradable refers to substances or objects that can be broken down naturally by microorganisms such as bacteria, fungi, and other biological processes into water, carbon dioxide, and organic matter.

Understanding biodegradability is crucial for assessing the environmental impact of materials and waste. Biodegradable materials decompose relatively quickly and reduce the accumulation of waste, thereby minimising pollution and conserving ecosystems.

This concept is vital for evaluating sustainability practices and developing environmental management strategies that align with ecological health and resource conservation.
