Biodegradability and compostability: what’s the difference?

About the green and respect for nature, one of the first notions that we absolutely must know is the difference between a biodegradable product and a compostable product.

Let’s discover in detail what’s mean these two terms that may seem synonyms, but then inside enclose an infinite number of differences.

Biodegradability.
This word means the ability of a substance, or of an organic material, to deteriorate and return to its starting shape (if the biological process is complete) such as water, anhydrite carbon dioxide and methane.

In this way it becomes possible to dispose of organic wastes, but to ensure that this process is effective it’s necessary to define the place and the duration of the process. It’s clear that in hot and humid environments the biodegradation will be faster, but for this there are industrialized places suitable for speeding up the processes (on average a biodegradable material to decompose itself takes more than 3 months).

Compostability.
This term refers to the ability of an element to be transformed into compost, the result of aerobic biodegradation and that takes the appearance of a fertile soil (having regard to the considerable presence of organic substances) usable as fertilizer.

The composting process occurs both naturally and in a controlled manner and desired by man in suitable places and that facilitate the phenomenon.

In nature, the organic materials (as wastes, sawdust, wood chips, etc.), produce heat and emit steam, as if they were burning without flame. During the course of this process the microorganisms present in the materials, consume the nutrients transforming the wastes into compost in less than 3 months.

Some of the materials that we use is the PLA, a green element compostable that respects the environment both to be produced itself that to be disposed of.
