DEGRADATION PROCESS
The degradation process starts with the heat of the extrusion process and continues in two
steps. In step one, chemical degradation happens either by ultraviolet light, heat, oxygen or
film stress, where over time the molecular structure of the product is reduced significantly.
The film will become fragmented. This process is irreversible and continues to a point where
the film becomes water wettable. This is step two, called biodegradation, where the micro -
organisms attach themselves and consume the remnants.

RESULT & DEGREE OF DEGRADATION
100% of the product degrades after degradation process is completed. The result of the
degradation is carbon dioxide, water and biomass.
ENVIRONMENTAL CONDITIONS NEEDED FOR DEGRADATION
Significantly, the KR-OXO film does not need a biologically active environment to start
degrading – this will happen even if the plastic is left in the open air! This is very important if
we are to address the serious litter problems caused by waste plastic. The factors that
accelerate degradation: ultraviolet light, heat, oxygen, and film stress (such as pulling and
tearing). Once the process is initiated it is irreversible and will continue in a landfill or under
water.

COMPARISON WITH BIO OR PHOTO DEGRADABLE

Oxo degradable product degrades over time and is speeded up by light, heat or stress and
slowed down by cold. It cannot be stopped. Bio degradables will only degrade once buried
and microbes are present. Photo degradables will only degrade with UV light. The product
will degrade even if unfortunately dropped as litter. With this property, oxo degradable
products are especially suitable for the plastic packages that end up in landfill or as litter.

TIME NEEDED FOR DEGRADATION
As little as sixty days or as long as five to six years. The degradation time can be adjusted.
With our standard formulation it should give minimum six months to around eighteen months
full useful product life.
