This document provides an overview of bioplastics, including their classification and applications. It discusses that bioplastics are made from renewable sources like plants rather than petroleum, and are often biodegradable. The main types of bioplastics covered are starch-based, polylactic acid, and aliphatic polyesters. Current applications include packaging, food service ware, electronics, and more. The document also notes challenges to bioplastics such as cost, but that the field promises to help the environment and reduce dependence on fossil fuels as the technology advances.

3. An overview to plastics
• These are synthetic polymers made up of complex organic compounds
produced by polymerization, Capable of being
 Molded,
 Extruded,
 Cast into various shapes and films,
 or drawn into filaments and then used as textile fibers
• These are typically organic polymers of high molecular mass mostly
derived from petroleum sources i-e., oil and gas Therefore, they contain
the chemical elements carbon and hydrogen, Oxygen, nitrogen, sulfur,
and other elements often present as well.

4. Why bioplastics ?
 Fossil fuel are depleting
 Burning of some plastics release very toxic fumes e.g. dioxin
 Biggest threats are the environmental issues, such as
o toxic pollutant e.g. BPA which is endocrine disruptor
o Green house gas
o Plastic trash in the ocean gyres
o Conventional plastics degrade very slowly ,lead to enlarged landfills.
 Plastic bags are causing major problems to wildlife because animals often eat or
inhale these bags, mistaking for food, get tangled in it and starve to death.

5. BIOPLASTICS
 Bioplastic is a biodegradable material
that come from renewable sources ,
such as vegetable fats and oils, corn
starch, straw.
 The term “bioplastics” is actually used
for two separate things:
o Bio-based plastics
o Biodegradable plastics

bioplastics

8. Starch based bioplastics
 They constitute about 50% of the
bioplastic market. Starch-based
bioplastics are comprised of starch,
cellulose, chitosan, and protein.
 Pure starch possesses the characteristic
of being able to absorb humidity,
therefore Flexibiliser and plasticizer such
as sorbitol and glycerin are added so the
starch can also be processed ther.mo-
plastically.

9. Polylactic acid plastics
 PLA is a transparent plastic produced from
cane sugar or glucose.
 Enzymes are used to break starch in the plants
down into glucose, which is fermented and
made into lactic acid. This lactic acid is
polymerized and converted into a plastic called
polylactic acid.
 These are used in the plastic processing
industry for the production of foil, moulds,
cups and bottles. Mulch film made of PLA

11. Aliphatic bio polyester
• Aliphatic polyesters can be considered as
representatives of synthetic biodegradable
polymers.
• The aliphatic bio polyesters are mainly
 Polyhydroxy alkenoates (PHAs)
 Poly-3-hydroxybutyrate (PHB)
20XX presentation title 11

12. Polyhydroxy alkenoates(PHA)
 These are linear polyesters produced in nature by bacterial
fermentation of sugar. They are produced by the bacteria to store
carbon and energy.
 These plastics are being widely used in the medical industry
Poly-3-hydroxybutyrate (PHB)
 The biopolymer poly-3-hydroxybutyrate (PHB) is a polyester produced
by certain bacteria processing glucose, corn starch or wastewater.
 It produces transparent film at a melting point higher than 130 degrees
Celsius, and is biodegradable without residue.

13. Advantages of bioplastics
 The need of replacement for the petroleum based plastic with
bioplastics is just because Producing conventional plastics
consumes 65% more energy than producing bioplastic.
 Conventional plastic are mostly toxic. Plastics last a long time
and do huge damage to environment. Therefore, plastic is
absolutely unsustainable and bioplastic is more sustainable.
 Bioplastics saves 30-80% of the greenhouse gas emissions
 Compost derived in part from bioplastics increases the soil
organic content as well as water and nutrient retention, with
reducing chemical inputs and suppressing plant diseases.

17. Recent challenges OR drawbacks
Economically somewhat unfeasible
Some energy still comes from standard petroleum sources cutting the
goal of bioplastic.
Some of the usual characteristics of conventional plastics are usually
absent
20XX presentation title 17

18. Conclusion
important and exciting new field
promises to help save the environment, slows the depletion of
non-renewable resources.
still a technology in its infant phases implementation of the
correct disposal methods and corresponding infrastructure are
vital if the bioplastics industry is to flourish and deliver
environmental benefits.
