That undergoes significant changes in its chemical structure

when subjected to various specific environmental conditions, resulting in a loss of properties

that can be measured by standard methods, in a given period of time.

That undergoes degradation resulting from the action of naturally occurring microorganisms

such as bacteria, fungi and algae about 6 months:

There is no reference to the amount of time needed for degradation or the type of physical and

chemical quality attributes of the end product .

That undergoes degradation by biological processes during composting to yield carbon dioxide water,

inorganic compounds and biomass at a rate consistent with

other compostable materials and leaves no visible, distinguishable or toxic residue

Material to which a metal-based additive is added to accelerate

degradation by sunlight (UV), heat and / or mechanical stress.

This first degradation results in small fragments, often invisible to naked

eye, that could be biodegraded in a second degradation phase.
