American Profol cast polypropylene films containing EcoPure™ additive have been shown to biodegrade under ASTM D5511-02 (Standard test method for determining anaerobic biodegradation of plastic materials under high-solids anaerobic-digestion conditions) conditions.* These conditions are designed to simulate anaerobic landfill conditions.
Our biodegradable plastic films manufactured with EcoPure™ additive are shelf stable and will not begin to biodegrade until the film is in contact with microorganisms commonly found in dirt or landfills. This technology is not dependent upon UV light, heat, or mechanical stress in order to degrade the polymer. Thus, our polypropylene films will remain shelf-stable for extended use applications.
Biodegradable Plastic Technology:
EcoPure™ facilitates the breakdown of the large polymer molecules into smaller organic species that are able to be consumed by microorganisms inherent in typical landfill or compost environments. It does this by first expanding the molecular structure of the plastic via water accumulation, which makes the polymer more accessible to microorganisms. It also adds nutrients that promote colonization of microbes on the polymer. The polymer chain is then broken down by the enzymes that are secreted by the microorganisms. Like any organic material that is biodegraded, the plastic will create byproducts, most of which are useful, including humus (which can be used to make soil richer), carbon dioxide, and methane (which can be used as fuel). This biodegradation process can take place aerobically (where there is oxygen, such as in a compost facility) or anaerobically (where there is no oxygen, such as in a sealed landfill).
