Description

Imagine leaving an apple core in your garden. Over time, it doesn't just stay there – it breaks down, returning to the earth and nourishing the soil. That's what "biodegradable" means! It describes materials that can be broken down naturally by living organisms like bacteria or fungi. Think of fallen leaves, food scraps, or even certain types of packaging.

Not everything is biodegradable. Plastic, for example, takes hundreds of years to decompose (if ever!). Choosing biodegradable products – like compostable bags or wooden toys – helps reduce landfill waste and is kinder to the planet. You'll often see this word used when talking about environmental concerns and sustainable living. It's a small word with a big impact!
