Oxo-degradable material uses heat and light to break down material.  Problems arise due to heat or light starting the degrading process prematurely.

Oxo-degradation needs heat and light to start and continue the degrading process. The process stops when put buried in a typical landfill where heat and light are nonexistent.

Oxo-degradable material does not degrade in the ocean, ponds, streams or other natural bodies of water.

Oxo-degradable additives use heavy metals to start the degradation process.
These eventually enter the environment.

PPI 4-20™ Products

Differ from oxo-degradable products because they are not affected by heat or light.  Degradation process only starts and continues in environments where microbes are active such as landfills, compost facilities (commercial & home) and natural bodies of water (ocean, streams & ponds).

Have no specific shelf life or storage requirements.

Do not contain any heavy metals.

Are easily recycled.
