What are BIOPLASTICS ? • BIOPLASTICS or organic plastics are a form of plastics derived from renewable biomass sources, such as vegetable oil, corn starch, pea starch, or Microbiota, Microbiota rather than fossil-fuel plastics which are derived from petroleum. • Biodegradable plastics combine the utility of plastics (lightweight, resistance, relative low cost) with the ability to completely and fully biodegrade. Page 4

Types of bio plastics The different types of bio plastics include – • Starch Based Plastics • Polyhydroalkanoates ( PHA’s ) • Poly-3 -hydrobutyrate ( PHB’s ) • Polylactic Acid ( PLA) • Oxo - Biodegradable Plastics • Genetically Modified Plastics Page 5

Starch based BIOPLASTICS • Among the different types of biodegradable plastics, Starch based plastics constitute about 50% of the bioplastics market. Thermoplastic starch, starch such as Plastarch Material, Material currently represents the most important and widely used bioplastic. • Flexibiliser and plasticizer such as sorbitol and glycerin are added to the starch. By varying the amounts of these additives, the characteristic of the material can be tailored to specific needs (also called "thermoplastical starch"). starch Page 6

Ingredients Here, the main ingredients used are - CORNFLOUR, CORNFLOUR WATER , GLYCERIN, GLYCERIN and VINEGAR Page 7

Chemistry Inside • Corn flour contains STARCH, STARCH which is the main ingredient of the Bioplastic. • Basically, Starch is made of long chains of glucose molecules joined together. • Strictly, it contains two polymers: AMYLOSE and AMYLOPECTIN Page 8

Polymers in Starch • AMYLOSE This is a long straight-chained polymer. This is a very useful polymer as it would give strength to the plastic. Page 9

Polymers in Starch • AMYLOPECTIN This is branched. from branched When starch is dried an aqueous solution it forms a film due to hydrogen bonding between the chains. However, the AMYLOPECTIN inhibits the formation of the film, film as it makes the plastic brittle. Reacting the starch with a chemical like vinegar breaks down the amylopectin, amylopectin giving strenght to our plastic. Page 10

Process of making Bioplastic GREENER EARTH CORNFLOUR • 1 tablespoon BIODEGRADA BLE PLASTIC WATER • 1 tablespoon GLYCERIN • ½ tablespoon VINEGAR Page 11

Giving different properties Varying the quantity of vinegar accordingly can give different properties to the plastic • if less amount of vinegar is used, then the plastic obtained would be hard and stiff. • if more amount of vinegar is used, then the plastic obtained would be tensile and flexible. Page 12

applications • Biodegradable bioplastics are widely used for disposable items, items such as packaging and catering items. • Biodegradable plastics are also used for organic waste bags, bags where they can be composted together with the food or green waste. Page 13

Benefits Bioplastics can ensure a greener and sustainable future as it • Takes Less Time to Break Down Bioplastic, easily degrades when discarded, thus reducing tons of petroplastic that cannot degrade. • Renewable The biggest advantage of bioplastic is that these plastics are made from renewable sources. Unlike fossil fuels including oil, these resources will not be depleted within a century. Page 14

Benefits • Non Toxic Bioplastics do not have any chemicals or toxins. This plastic harmlessly breaks down and gets absorbed into the earth. • Reduces CO 2 Emissions When bioplastics degrade, there are very few greenhouse gas and harmful carbon emissions. Bioplastics represent a 42% reduction in carbon footprint. Page 15

Benefits • Cost Effective and Energy Efficient Producing bioplastics uses 65% less energy than it takes to produce petroleum-based plastics, making bioplastics the energyefficient choice. • Easier to Recycle Bioplastics are created from fully biodegradable materials. Thus, recycling them takes much less energy. Page 16

Drawbacks Despite that this plastic is eco - friendly, its has not become popular in its use mainly because • Limited Shelf Life Bio plastics do not have a long life as they degrade very quickly. Thus, the conventional plastics are preferred more because of their excellent durability and long life. • Development of Plastic Consuming Bacteria It is also possible that bacteria will eventually evolve the ability to degrade synthetic plastics as well. Page 17

Drawbacks • Food Shortage Bio plastic production cannot be increased unless there is a pressure on the food system. Most of the corn that was used for human consumption is now being used for making bioplastic. Thus, there is a future possibility of food shortage. It has drawn attention to the importance of using non-edible plant resources to produce bio plastics. • Low Mechanical Strength The mechanical strength of starch based bio plastics is poor as compared to regular plastic.
