The document summarizes an experiment to synthesize bio-plastics using banana peels and coconut dust. It describes how banana peels and coconut dust were prepared as raw materials. The experiment involved mixing banana peel starch paste with hydrochloric acid and sodium hydroxide, then adding glycerol and filler materials. The mixture was formed into specimens and baked to produce bio-plastic samples. Potential applications of bio-plastics include bags, food packaging, and other products that can be composted at the end of their usage. The conclusion states that bio-plastics are more environmentally friendly than traditional plastics and could replace conventional plastics in the future.

4. Introduction
Bioplastics are a type of plastic that can
be made from natural resources such
as vegetable oils and starches. Since
bioplastics are plant-based products,
the consumption of petroleum for the
production of plastic is expected to
decrease by 15–20% by 2025.

5. ECONOMY OF BIO-PLASTICS
Catering products: 450,000 tonnes per year
Organic waste bags: 100,000 tonnes per year
Biodegradable mulch foils: 130,000 tonnes per year
Biodegradable foils for diapers 80,000 tonnes per
year
Diapers, 100% biodegradable: 240,000 tonnes per
year
Foil packaging: 400,000 tonnes per year
Vegetable packaging: 400,000 tonnes per year
Tyre components: 200,000 tonnes per year
Total: 2,000,000 tonnes per year

6. Raw Materials
• Banana peels
• Starch
• Hydro chloric acid
• Sodium hydroxide
• Glycerol
• Coconut Dust

7. EXPERIMENT
PREPARATION of starch
Musa peels and Starch are boiling with water for 60
minutes over 373K.
The water is decanted from the beaker and the peels are
now left to dry on
filter paper for about 45 minutes.
After the peels are dried. The peels are grinding by the
mixer grinder over up
to 60 minutes and Starch solution was boiled 15 minutes.
Now starch paste
was ready to use

8. Preparation of coconut Dust
Crushing the cocus-nucifra dust with aid of knife.
To dry the dust in front of sunlight over 48 hour.
And washing with cold water, to remove impurities. Than dry
the dust in front of sunlight over 48 hour. Now the dust is
eligible for add as a filler.

9. o 500gm of paste is placed in a beaker
o 60ml of (0.5 N) HCL is added to this mixture and stirred using glass
rod. o 40ml Plasticizer is added and stirred.
o 0.5 N NaOH is added according to pH desired,
o And adding filler as per 0%, 5%, and 10% respectively.
o Then add gelatin for more adhesiveness for filler with PLA.
o The mixture is spread on a ceramic tile or petri dish and this is put in
the oven at 393K and is baked till dry.
o Than the specimen was out from oven, cool the specimen overnight.
o Now the specimen eligible for testing.
Synthesis of Bio Plastic

10. Application of Bio Plastic
● Foils made from bio plastics can be used to
produce bio-waste bags, compostable
●
● bags, bags made from renewable resources, food
wrapping and shrink films to pack
●
● beverages and also for other applications. The
main advantages of the use of bio
●
● plastics are environmental aspects, higher
consumer acceptance, increased shelf life
●
● of the products and composting as an end of life
treatment of compostable products.

11. Conclusion
● The bio-plastics are the new generation plastics which is become
popular in this world only because of its significant property like bio-
degradable.
● It can be quoted as the “eco-friendly product”
● These plastics are going to make tremendous change in the world
and we can except that it will replace the conventional plastic in
future.
