	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.

The general structure of polyhydroxyalkanoates

• 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.

Lactic acid polymerization to PLA

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)
