This presentation discusses the plastic ban and plastic pollution. It notes that plastics are polymers made from carbon, hydrogen, oxygen and other elements. Rapid population growth and waste generation have led to 65 million tons of waste in India by 2010. Plastics are classified as thermoplastics and thermosetting, with thermoplastics able to be remolded and thermosetting not. Common plastic products are bags, sheets, furniture and more. While plastics are light, strong and cheap, they are also non-renewable and cause pollution when littered or burned. The presentation calls for reducing disposable plastics, recycling, cleaning areas, using reusable bags, and educating about alternatives through taxes.
2. The term “plastics” includes materials composed of various elements
such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulphur.
Plastics are macromolecules, formed by polymerization and having the
ability to be shaped by the application of reasonable amount of heat and
pressure or any other form of forces.
It is one of the few new chemical materials which pose environmental
problem.
Polyethylene, polyvinyl chloride, polystyrene is largely used in the
manufacturing of plastics.
3. Rapid population growth, urbanization and industrial growth have led
to severe problem of waste generation in urban centres.
The waste quantities increased from 46 million tones in 2001 to 65
million tones in 2010.
Report says that per capita per day production will increase to 0.7 kg in
2050.
The characteristics of waste depends on various factors such as food
habits, traditions, lifestyle, climate etc.
Awareness
4. Plastics, depending on their physical properties, may be classified as thermoplastic or
thermosetting plastic materials.
Thermoplastic materials can be formed into desired shapes under heat and pressure and
become solids on cooling. If they are subjected to the same conditions of heat and
pressure, they can be remoulded.
Thermosetting materials which once shaped cannot be softened/ remoulded by the
application of heat.
Out of total uses of plastic, 8 % areThermoplastic and 20% areThermosetting.
TYPES OF PLASTICS
10. Advantages of plastic:
• Advantages of plastic are light in weight.
•They can be easily moulded and have excellent finishing.
•They possess very good strength and toughness.They possess good shock
absorption capacity.
• Advantages of plastic are corrosion resistant and chemically inert. •They
have low thermal expansion of co-efficient and possess good thermal and
electrical insulating property.
• Advantages of plastic is very good water resistant and possess good
adhesiveness.
• Plastic is strong, good and cheap to produce.
• Plastic is a recycling process and it does not decompose.
• Plastic bottles can be reused and restored over again and again.
• Plastic is one of the unbreakable.
• Plastic is used for building, construction, electronics, packaging and
transportation industries.
• Used to make -Water bottles, pens, plastic bags, cups etc.
• Advantages of plastic areVery cheap to make
• Durability
11. Disadvantages of plastics:
• Plastic is a non renewable resources.
• Plastic is softness.
• causes CANCER
• Disadvantage of plastics are embrittlement at low
temperature.
• Disadvantage of plastics are deformation under load.
• Disadvantage of plastics are low heat resistant and poor
ductility.
• Disadvantage of plastics are combustibility. • Produces toxic
fumes when it is burnt.
• It is a recycle process, but it is very costly
12. What CanWe Do?
Cut disposable plastics out of your
routine.
Recycle.
Take Responsibility .
Clean up your reachable places .
Start using green bags instead of
plastic bags.
