Oxo-biodegradability is a two-phase process that enables plastics to degrade and eventually integrate into the environment. This process can be tailored to meet specific requirements, with degradation periods adjustable based on customer needs.
In the oxidation phase, exposure to oxygen, heat, and ultraviolet (UV) light initiates the breakdown of the polymer structure. This leads to a reduction in molecular weight, causing the material to fragment into smaller pieces. As the polymer chains shorten, the plastic loses its strength, becoming brittle and less durable.
The biodegradation phase follows, during which microorganisms consume the fragmented material, converting it into biomass, carbon dioxide (CO₂), and water (H₂O). This ensures the plastic decomposes naturally, minimising long-term environmental impact.
To ensure the effectiveness and reliability of oxo-biodegradable plastics, manufacturers conduct rigorous testing in collaboration with the Institutes for Scientific Research. Samples are also sent to specialised laboratories for quality control degradation profile testing, which assesses the suitability of a formulation for a given application.
