Oxo-Biodegradation of Full Carbon Backbone Polymers

Oxidation and Biodegradation of Full Carbon Backbone Polymeric Materials under Different Environmental Conditions

Beschreibung

The present work has been focused on the mechanism of physical-chemical processes (abiotic) that promote as ultimate stage the biodegradation of full carbon backbone polymers, thus transforming these polymers in eco-compatible materials. In particular, the investigations undertaken in the present PhD thesis work was the evaluation of the rate of biodegradation of oxidized and degraded oxo-biodegradable polyolefin samples (PE, PP, PS) under aqueous, soil and compost conditions. Based on these criteria polyolefin (PE, PP and PS) film samples formulated with different pro-oxidant (type and content) based on transition metal organic salts able to promote oxidative degradation/biodegradation by abiotic and/or biotic actions have been ascertained into three tiers. Tier 1 Acceleration of samples aging in standard tests for both thermal and photo-oxidation processes and determination of the degree of abiotic degradation. Tier 2 Monitoring of the biodegradation of the pre-treated samples in respirometric apparatus. Tier 3 Assessment of interactions between polymeric materials and microbes and of any toxicity effect of the metabolized polymer fragments.
