  • Biodegradation is generally considered as consisting of either enzyme-catalyzed hydrolysis, non-enzymatic hydrolysis, metabolic action, or both.
  • the enzymes may be either endoenzymes which cleave the internal chain linkages within the chain or exoenzymes which cleave terminal monomer units sequentially.
  • Biodegradation is a functional decay of material, e.g. loss of strength, substance, transparency, or good dielectric properties where it is known to be identifiable with exposure of the material to a living environment, which may itself be very complex, and the property loss may be attributable to physical or chemical actions as first steps in an elaborate chain of processes.
  • a biodegradable polymer is a high molecular weight polymer that, owing to the action of micro- and/or macroorganisms or enzymes, degrades to lower molecular weight compounds.
  • Natural polymers are by definition those which are biosynthesized by various routes in the biosphere. Proteins, polysaccharides, nucleic acids, lipids, natural rubber, and lignin, among others, are all biodegradable polymers, but the rate of this biodegradation may vary from hours to years depending on the nature of the functional group and degree of complexity. Biopolymers are organized in different ways at different scales. This hierarchical architecture of natural polymers allows the use of relatively few starting molecules (i.e. monomers), which are varied in sequences and conformations at molecular-, nano-, micro-, and macroscale, forming truly environmentally adaptable polymers.
  • the repetitive units of synthetic polymers are hydrolyzable, oxidizable, thermally degradable, or degradable by other means. Nature also uses these degradation modes, e.g., oxidation or hydrolysis, so in that sense there is no distinction between natural or synthetic polymers.
  • the catalysts promoting the degradations in nature (catabolisms) are the enzymes, which are grouped in six different classes according to the reaction catalyzed.
  • oxidoreductase for catalyzing redox reactions
  • transferase for catalyzing transfer of functional group reactions
  • hydrolase for catalyzing hydrolysis
  • lyase for catalyzing addition to double bond reactions
  • isomerase for catalyzing isomerization
  • ligase for catalyzing formation of new bonds using ATP.
  • Biodegradation of oxidizable polymers is generally slower than biodegradation of hydrolyzable ones. Even polyethylene, which is rather inert to direct biodegradation, has been shown to biodegrade after initial photo-oxidation. An oxidized polymer is more brittle and hydrophilic than a non-oxidized polymer, which also usually results in a material with increased biodegradability. Means to accelerate the oxidation of polymers (for example polyolefins) are presented according to one embodiment of the present invention. [0051] For example, by combining a nickel dithiocarbamate (photo antioxidant) with an iron dithiocarbamate (photo proxidant), a wide range of embrittlement times may be obtained.

  • Microbial or enzymatic attack of pure aromatic polyester is increased by exposure to certain microbes, for example Trichosporum, athrobacteria and Asperyillus negs.
  • the second is enzymatic hydrolysis which produces water-insoluble intermediates that can be assimilated by microbial cells.

Fungi grow at temperatures ranging up to 45 °C, although optimum growth rates generally occur at temperatures between 30 °C and 37 °C. Because most fungi require oxygen, they may only be available for cellulosic, plastic and rubber (CPR) degradation before closure and for a relatively short time (compost environment). There is some evidence that anaerobic fungi may degrade lignocellulosic materials.

Conformational changes in these enzymes may be induced by the changes in pH, temperature, and other chemical additives.
