Biodegradable vs. Compostable: What's the Difference?
Edited by Huma Saeed || By Sawaira Riaz || Published on November 18, 2023
Biodegradable items break down naturally over time, while Compostable items decompose in compost conditions to produce nutrient-rich humus.
Key Differences
Biodegradable materials are substances that can be broken down by natural processes and decomposed by microorganisms, fungi, or bacteria. This term simply means that a product can disintegrate into natural elements with the help of living organisms.

On the other hand, Compostable materials go a step further. They not only break down but do so within a specific timeframe in composting conditions. Compostable items are designed to decompose in composting systems and transform into nutrient-rich compost or humus.

An important distinction between Biodegradable and Compostable items is the end result. While Biodegradable materials break down, they might leave behind metal residue or other tiny fragments. Compostable materials, conversely, fully decompose, leaving no toxic material behind.

Furthermore, the time frame for decomposition varies. Biodegradable items might take years, even decades, to fully break down, depending on environmental conditions. Compostable materials, in contrast, decompose within a matter of weeks to months in a compost system.
