By definition, biodegradable materials are formed or organic compounds which can thus be broken down by living organisms, such as bacteria, fungi, or water molds, and reabsorbed by the natural environment. [13] Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14]
Biodegradable polymers are classified into three groups: medical, ecological, and dual application, while in terms of origin they are divided into two groups: natural and synthetic. [18] The Clean Technology Group is exploiting the use of supercritical carbon dioxide , which under high pressure at room temperature is a solvent that can use ...
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]
[4] [5] Composting offers an environmentally superior alternative to using organic material for landfill because composting reduces methane emissions due to anaerobic conditions, and provides economic and environmental co-benefits. [6] [7] For example, compost can also be used for land and stream reclamation, wetland construction, and landfill ...
Poly(ethylene adipate) or PEA is an aliphatic polyester. [3] It is most commonly synthesized from a polycondensation reaction between ethylene glycol and adipic acid. [4] PEA has been studied as it is biodegradable through a variety of mechanisms and also fairly inexpensive compared to other polymers. [5]

Chemically, polydioxanone is a polymer of multiple repeating ether-ester units. It is obtained by ring-opening polymerization of the monomer p-dioxanone.The process requires heat and an organometallic catalyst like zirconium acetylacetone or zinc L-lactate.
