Biodegradable And Non Biodegradable Polymers Biodegradable and non biodegradable polymers Most of us might have observed that whenever we dump household solid wastes at dumpsites, a part of them disappears after few days (biodegradable wastes) but some of them start accumulating at that place (non-biodegradable wastes).

Polymers are macro molecules composed of more minuscule units called monomers. Polymers can be either synthetic or natural, such as cellulose which is a natural polymer found in plants. Research has shown that replacing natural monomers into synthetic polymers creates polymers that are biodegradable in.

The biodegradable polymers can be classified according to their chemical composition, origin and synthesis method, processing method, economic importance, application, etc. In the present chapter, biodegradable polymers classified according to their origin into two groups: natural polymers which obtained from natural resources and synthetic polymers which produced from oil.

Both synthetic polymers and biologically derived (or natural) polymers have been extensively investigated as biodegradable polymeric biomaterials. Biodegradation of polymeric biomaterials involves cleavage of hydrolytically or enzymatically sensitive bonds in the polymer leading to polymer erosion (9).

Biodegradable polymers are those polymers which get decomposed by the process of biodegradation. Biodegradation is defined as a process carried out by biological systems (usually fungi or bacteria) wherein a polymer chair is cleaved via enzymatic activity.And it is called BIODEGRADABLE POLYMERS. There are essentially following three elements for the biodegradation process which needs to.

Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO 2, N 2), water, biomass, and inorganic salts. These polymers are found both naturally and synthetically made, and largely consist of ester, amide, and ether functional groups.

Biodegradable polymers can be classified into two main categories; agro-polymers and biodegradable polyesters (Averous and Pollet, 2012). The biopolyesters are predominantly obtained from renewable sources, that are capable of “undergoing decomposition into carbon dioxide, methane, water, inorganic compounds and biomass” (Averous and Pollet, 2012).

Essay On Biodegradable Polymers Slideshare

Biodegradability of a polymer is basically based on chemical structure unlike from the source from which it is obtained. Thus, biodegradable polymers besides renewable-based sources (as discussed above) can also be made from fossil fuel sources. A few examples of such polymer are reviewed below. 5.4.1 Poly(butylene succinate).

Biodegradable polymers may be defined (3) as those which undergo microbial scission, resulting in photo-degradation, oxidation, and hydrolysis and alter the polymer through the degradation process. On the other hand, biodegradable polymers primarily decompose to carbon dioxide, methane, and inorganic compounds by the enzymatic action of microorganisms within a specified period of time.
