What is the controversy behind banning oxo-biodegradables?

Oxo-biodegradables do not meet international biodegradation requirements, which has caused the authorities to prohibit their use, contrary to their formulators who defend their benefits in the environment.

Explanation:

Oxo-biodegradables are a type of plastic that can be broken up into tiny pieces, but that is not biodegraded by the action of nature. In this case, this type of plastic does not meet international biodegradation requirements, in addition, it can cause pollution, as its mini particles can affect rivers, soils, crops, in addition to being dispersed in the air and being eaten by animals.

The great controversy is that the creators of this type of plastic defend their benefit in the environment, however the authorities, considering the polluting potential of oxo-biodegradables, prohibited its use.
