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. [3]
The term Biodegradable Plastics refers to materials that maintain their mechanical strength during practical use but break down into low-weight compounds and non-toxic byproducts after their use. [18] This breakdown is made possible through an attack of microorganisms on the material, which is typically a non-water-soluble polymer. [4]
Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14] Indeed, the sustainability benefits of drop-in biobased plastics occur at the beginning of the material life cycle, but still, when manufactured, their structure is identical to their fossil-based counterparts.
It is nontoxic and biodegradable, so it does not have to be removed after recovery. [ 8 ] TephaFLEX is a bacterially derived poly-4-hydroxybutyrate, manufactured using a recombinant fermentation process by Tepha Medical Devices, intended for a variety of medical applications that require biodegradable materials such as absorbable sutures .
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 ...
This material can be used for biodegradable, homogeneous, dense films that are very useful in the biomedical field. Alginate: Alginate is the most copious marine natural polymer derived from brown seaweed. Alginate biopolymer applications range from packaging, textile and food industry to biomedical and chemical engineering.
