Objective
To create a Technology landscape report on "Biodegradable Packaging for Liquids"
Comment: The idea is to find out the innovative market players in this technology area, those are the players that are the most technologically advanced in the market place. Intellectual Property that these players hold is taken as a measure of their technological prowess in this particular area. We have used Patents and Scientific articles to point out the innovative and technologically advanced market players.
Search methodology
| Search strategy | 1. Various class codes and keywords were retrieved for conducting the search related to Biodegradable Packaging from relevant patents, thesaurus and patent databases and scientific articles. |
| 2. The database used for patent search is Thomson innovation. (Refer section 6) | |
| Keywords | biodegradable, bio-disintegratable, biopolymer, bioplastic,PLA, PHA, PHB, PHBV, etc. |
Background
The environmental and sustainability issues, the increasing cost of solid waste disposal, dioxin emission from waste incineration have made synthetic polymers unattractive. This has led to the development and production of biodegradable polymers. Polyhydroxyalkanoates (PHAs) are the intracellular inclusion in some bacteria. The property of PHA range from stiff, brittle to rubber-like and is a suitable alternative for the synthetic plastic.
- n=1 R=hydrogen poly(-3-hydroxypropionate)
- methyl poly(-3-hydroxybutyrate)
- ethyl poly(3-horoxyvalerate)
- propyl poly(-3-hydroxyhexanoate)
- pentyl poly (-3-hydroxyoctanoate)
- nonyl poly (-3-hydroxydodecanoate)
- n=2 R=hydrogen poly (-4-hydroxybutyrate)
- n=3 R=hydrogen poly (-5-hydroxyvalerate) (https://tspace.library.utoronto.ca/bitstream/1807/3487/1/jb04003.pdf.
Polylactic acid (PLA) is another biopolymer with environmental benefit. Polylactic acid (PLA) is a rigid thermoplastic polymer and can be semicrystalline or amorphous. The backbone of PLA is L(_)-lactic acid (2-hydroxy propionic acid) which is a natural and most common form of the acid. D(_)-lactic acid can also be produced by microorganisms or through racemization. (http://www.jimluntllc.com/pdfs/polylactic_acid_technology.pdf)
