Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...
There are vast examples and applications of biodegradable polymers. Bio-based packaging materials have been introduced as a green alternative in the past decades, among which, edible films have gained more attention due to their environmentally-friendly characteristics, vast variety and availability, non-toxicity, and low cost.
Boxed products made from bioplastics and other biodegradable plastics. Few commercial applications exist for bioplastics. Cost and performance remain problematic. Typical is the example of Italy, where biodegradable plastic bags are compulsory for shoppers since 2011 with the introduction of a specific law. [16]
An example of a compostable polymer is PLA film under 20μm thick: films which are thicker than that do not qualify as compostable, even though they are "biodegradable". [14] In Europe there is a home composting standard and associated logo that enables consumers to identify and dispose of packaging in their compost heap.
Biodegradable technology is established technology with some applications in product packaging, production, and medicine. [31] The chief barrier to widespread implementation is the trade-off between biodegradability and performance. For example, lactide-based plastics are inferior packaging properties in comparison to traditional materials.

Furthermore, plastic bottles and plastic bags that end up in landfills are frequently consumed by animals, which then clogs their digestive systems and leads to death. [4] Because of the substantial growth in plastic consumption, biodegradable additives are becomingly increasingly necessary to increase the rate of degradability of common plastics.
Biodegradable bags still strong enough to carry shopping after three years in the ground show that 'biodegradability' isn't all it's cracked up to be. When biodegradable plastic is not ...
