INTRODUCTION
 Biopolymers are polymeric biomolecules which contain
monomeric units that are covalently bonded to form
larger molecules.
They are solid ,higher molecular weight non-metallic
compounds
Biopolymers are biological macromolecule which can
be derived from renewable sources such as plants, animal
and living organisms.
Important property of biopolymers is
‘Biodegradability’

SCOE
There are three main classes of biopolymers based on
the differing monomeric units used and the structures of
biopolymers formed:
 Polynucleotide
Polypeptides
 Polysaccharides
Biopolymers and plastic are similar in appearance
Plastic product Biopolymer product

SCOE
Need 0f Biopolymers
Plastics materials are used world wide today its many
application. Most of these plastics are derived from
petroleum and they are not degradable.
Due to unorganized and improper disposal non degradable
plastics causing harm to the environment.
As per a survey conducted by Central Pollution Control
Board (CPCB) in 60 cities of the country, the plastic waste
generation is estimated to 15,000.0 tonnes per day.
To protect the needs of future generation from hazardous
environment, biopolymers is better option.

SCOE
POLYHYDROXYBUTYRATE (PHB)
 PHBs are short chain length Biopolymers of
Polyhydroxyalkanoates (3-5 carbons)
 Produced in nature by bacterial fermentation of sugars
and lipids
 Polyesters accumulated inside microbial cells as
carbon and energy source storage
 Produced under the conditions of :
• Low limiting nutrients (P, S, N, O)
• Excess carbon source
 Found in Alcaligenes eutrophus and accumulated
intracellularly as granules

SCOE
PROPERTIES OF PHB
 Some are stiff and brittle
Some are rubbery and mouldable
They act like polyesters thermoplastic properties similar to
polypropylene and polyethylene.
Moisture resistant, water insoluble, optically pure.
Excellent flexibility
Degrades at 180ͦ C without releasing any toxic gases

SCOE
Production and types of mechanisms
Microbial production
Isolation from totally natural sources.
Extraction from plants and algae.

FUTURE PROSPECTS
 We will use alternative carbon sources such as -
 pineapple peel, palm sugar, beet peel, coconut juice
,potato peel , orange peel.
Organic waste water,
Vegetable waste.
We Will perform fermentation process on laboratory scale
level.
 Analytical techniques –
• Fourier Transform-Infrared Spectroscopy(FTIS)
• Differential Scanning Colorimeter.(DSC)
