Oxo-biodegradable" plastic bags are based on a technology where an additive is added to conventional plastic material so that the plastic eventually fragments into micro-particles (normally within two to five years).

(ii) Microscopical, — when suitably mounted and examined under the microscope, thyroid shows the following: numerous smooth to striated hyaline fragments of colloids, of angular to irregular shape, that are colourless to pale yellow in water mounts, brown in Mallory’s stain and pink in solution of eosin, some of these fragments containing granules, minute vacuoles, crystalloidal bodies and cells; numerous irregular fragments of follicular epithelium staining brown with Mallory’s stain, the individual cells more or less polygonal to rounded-angular or irregularly cuboidal, often with prominent nuclei staining dark blue, their cytoplasm p ...[+++]urplish with Delafield’s solution of haematoxylin; slender glistening segments of capillaries of closely undulate outline; numerous slender segments of neuraxons; numerous aggregates of particles of intercellular substance and slender, mostly straight connective tissue fibres staining blue to greenish blue with a mixture of Mallory’s stain and solution of phosphotungstic acid, the bundles of fibres often appearing reddish in Mallory’s stain; few glistening fragments of blood vessels with serrated or crenated ends as viewed in water mounts; and

As a result of the oxidation of those additives, the plastic materials fragment into small particles, which remain in the environment.
