Biodegradable : Photo biodegradable polymer

The Biodegradable credit cards is a charging card that can be converted to soil, carbon dioxide ( CO2) and bio-pile over a meter using micro-organisms and bio degradation in this physical process. And as a plastic's biodegradability rests with the polymer's chemical properties, and not the origins of the biodegradable credit card from feed stock may be either Eco- or crude-based.

The length of the bio degradation process is highly dependent on environment al parametric quantity such as humidity and temperature, which is why claiming that a plastic is 'biodegradable' without any further context (i.e., in what time frame and under what environmental atmospheric condition ) is misleading. Compo stable charge plate are a subset of biodegradable charge plate , defined by the standard conditions and time frame under which they will biodegrade.

All compost able plastics are biodegradable, but not all biodegradable plastics would be considered compo-stable.

Compo-stable plastics

Compo-stable plastics are those plastics which have been tested and certified by a third party to adhere to international standards such as ASTM D6400 in U.S. for bio-degradation in an industrial composting facility environment.

Compo-stable plastics will disintegrate within twelve headroom and biodegrade at least 90% within 180 days in a municipal or industrial composting facility. Approximately 10% of solid material will be left-field field at the end of the six-month-long process in the form of valuable compost, or biomass and water.

Leftover Compost

Some standards also ensure that the leftover compost will be free of toxin , so the compost will not cause harm when the facility sells it for gardening or agricultural lotion . Oxo-degradable plastics are not biodegradable plastic, but rather a conventional plastic mixed with an additive will quickly shred into smaller and smaller pieces, called micro-plastics, but don’t break down at the molecular or polymer level like biodegradable and compo stable plastics. The resulting micro-plastics are left in the environment.
