Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.
Plastics have become ubiquitous in modern life but also present environmental challenges as waste. This document discusses recycling polymers (plastics) as a solution. It provides background on plastics, noting they are made from petrochemicals and come in various types based on their molecular structure. The document then discusses the environmental impacts of plastic waste, including taking up landfill space, releasing greenhouse gases, and harming wildlife. It stresses that identifying plastics by their identification code is important for effective recycling. Recycling polymers is advocated as it conserves resources and reduces environmental damage from plastic waste.
Plastic pollution involves the accumulation of plastic products in the environment that can harm wildlife and humans. Plastic pollution can occur through micro, meso, or macro debris based on size. Plastic pollution can upset the food chain if ingested by plankton, pollute water and land if dumped or stuck in places, and pollute air if burned openly. Plastic recycling recovers different types of plastic to reprocess them into new products unlike the original form. The recycling process involves sorting plastics by type, washing, shredding, extruding or melting plastics, and making new materials. Bioplastics are an alternative to conventional plastics as they are made from renewable plant sources like corn starch or sugar cane

About Biodegradable polymers, how to use it and reuse it
The document discusses plastics, their history, types, and environmental impacts. It provides details on common plastic polymers, how plastics are made, and their uses in various industries. The summary discusses the negative effects of plastic pollution, how plastics do not degrade and release toxic chemicals when burned. It also notes that only a small percentage of plastics are recycled due to the labor intensive process.
Plastic is derived from fossil fuels and is made through polymerization of hydrocarbon monomers into long carbon chains. It has various advantageous properties but also poses environmental challenges as plastic is slow to degrade and can release toxic chemicals. Most plastics produced are for packaging and building/construction. While recycling and alternative waste conversion methods exist, plastic waste management remains an important issue given its persistence and potential impacts on land, water, and living organisms. Strategies like reducing single-use plastic and improving waste collection infrastructure are needed to better address the plastic pollution problem.
This document discusses plastics, including what they are, their history, common types and uses. It also discusses how plastics can be prevented from polluting the environment through reduction, control and proper disposal methods. Reduction involves redesigning plastic products to use less material and reusing items more. Control involves ensuring plastics from industrial and household waste are properly contained and disposed of in landfills or recycling. Legislation also prohibits dumping plastics at sea. With improved management practices, the amount of plastic marine debris can be reduced.
Plastic bottles have several disadvantages, including that they take an extremely long time (500 years) to decompose in landfills. Additionally, plastic is difficult to recycle effectively as most plastic cannot be recycled and recycled plastic is often downcycled into lower quality products. A further disadvantage is that plastic production relies on non-renewable resources like oil and natural gas. Large quantities of discarded plastic end up polluting the environment and harming wildlife through ingestion and entanglement.

Plastics are polymers made of repeating monomer units chemically bonded together. There are two main types of plastics: thermoplastics which can be remolded and thermosetting plastics which cannot. Plastics have advantages like durability, safety and low cost but disadvantages include taking hundreds of years to decompose in landfills, releasing pollutants during production and disposal, and threatening wildlife when littered. Efforts to reduce plastic waste focus on recycling, developing biodegradable alternatives, and converting waste plastics into fuel.
This document describes the process of converting waste plastic into fuel through pyrolysis. Pyrolysis involves thermally degrading plastic in the absence of oxygen to produce solid, liquid, and gaseous fuels. The process uses a specially designed reactor heated to 350°C along with catalysts to cause the random depolymerization of plastics into fuel products. The machine used in pyrolysis consists of a reactor, catalytic cracker containing ZSM-5 zeolite catalyst, condenser to liquefy vapors, and nitrogen cylinder to provide an inert atmosphere. Converting waste plastic to fuel through pyrolysis solves disposal issues while producing valuable energy sources.

Plastics are synthetic polymers that can be molded into various shapes. They are made from petroleum and were first invented in the 1860s. Today, plastics have many uses including plastic bottles, containers, bags, and furniture. However, plastics also cause several issues. When disposed of improperly, plastics pollute the environment and can harm wildlife. Chemicals in some plastics have also been linked to health problems in humans. While plastics are inexpensive and durable, addressing their environmental and health impacts remains an ongoing challenge.
Plastics & it’s impact on the environment and health. Plastics are synthetic polymers derived mainly from petroleum and natural gas. While plastics are durable and inexpensive, they release harmful chemicals when broken down and cause significant pollution. Plastics do not biodegrade and accumulate as microplastics in the environment, harming wildlife and entering the food chain. Common plastic pollutants like BPA and phthalates have been linked to health issues like heart disease, infertility and cancer. To reduce risks, alternatives to plastic for food storage and minimizing single-use plastics are recommended.
Plastic bottles were developed in the early 20th century and became widely used after World War II. The key materials used are polyethylene terephthalate (PETE), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), and polypropylene (PP). These materials are chosen based on their properties like strength, flexibility, and barrier effectiveness. Plastic bottles are manufactured using blow molding processes and come in various colors, shapes, and sizes to suit different applications like water, soda, detergents and more. However, plastic waste is an environmental issue as most plastics do not decompose and recycling rates need improvement.
Rudrashis Biswas wrote a report on high density polyethylene (HDPE) for their 5th semester chemical engineering course. The report defined HDPE as a thermoplastic polymer produced from ethylene monomer. It discussed the history of HDPE's invention in the 1950s using catalysts. The report also covered the physical and chemical properties, production, applications, and advantages of HDPE, which include its strength, durability, recyclability, and resistance to chemicals and corrosion. It concluded with current and projected growth in global HDPE production and markets.

Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

36. ENVIRONMENTAL ISSUES ON CONSUMPTION
OF PLASTIC
• During polymerization process fugitive emissions are released.
• During product manufacturing various types of gases are released.
• Indiscriminate plastic waste disposal on land makes the land infertile due to its impervious nature.
• Burning of plastics generates toxic emissions such as carbon monoxide, chlorine, hydrochloric acid,
dioxin, furans, amines, nitrides, styrene, benzene, 1, 3- butadiene, ccl4, and acetaldehyde.
• Littered plastics give unaesthetic look and choke the drain.
• Garbage mixed with plastics interferes in waste processing facilities and also cause problems in
landfill operations.
• Plastic emit harmful voc(volatile organic compound) during incineration.
• Plastic waste dumped in ocean harmful to sustain marine life.
36
37. ENVIRONMENTAL ISSUES ON CONSUMPTION
OF PLASTIC
• Most of the plastic we consume will wind up in a landfill or in the ocean. It will never
biodegrade. It will only break down into smaller pieces making it even more of a hazard for
wildlife and for us. Plastic can contaminate the fresh water ,on leaching in water it easily enter
food chain and harm human health.
• Plastic uses vital non-renewable natural resources that could be put to better use elsewhere.
10% of our oil production is for plastic.
• Plastic can contaminate food with toxic chemical compounds.
• Plastic waste can leach out toxic chemical like BPA(a component harden plastic),phthalates (a
component make plastic flexible) causes neurological problem,cancer, birth defects,thyroid
problems,hormonal disorder and cardiovascular disease.

40. PLASTIC WASTE MANAGEMENT RULES, 2016 –
WHAT’S NEW?
Minimum thickness of plastic carry bags increased from 40 to 50 microns
Responsibility of local bodies and gram panchayat.
Responsibility of waste generator.
Collect back system and extended producer responsibility.
Responsibility of retailers and street vendors.
Registration of the shopkeepers and street vendor to getting plastic bag.

42. RECYCLING OF PLASTICS
Steps Involved in the Recycling Process:
Selection: the recyclers/reprocessors have to select the waste /scrap which are
suitable for recycling/ reprocessing.
Segregation: the plastics waste shall be segregated as per the codes mentioned in the
bis guidelines.
Processing: after selection and segregation of the preconsumer waste (factory waste)
shall be directly recycled. The post consumer waste (used plastic waste) shall be
washed, shredded, agglomerated, extruded and granulated.
42
45. ADVANTAGES OF RECYCLING PLASTIC
• Reduced oil consumption- recycling plastic cuts back on oil consumption, which is helping to
extend the lifespan of our remaining fossil fuel reserves.
On average, 1 ton of recycled plastic saves 16.3 barrels of oil
• Saving energy- recycling plastic still uses energy, but it usually requires less energy than
making fresh plastic. Recycling 1 ton of plastic saves the equivalent of 5,774 kilowatt-hours of
electric energy.
• Reducing waste- plastics break down slowly in a landfill. However, in the ocean, for example -
they can break down more quickly, but they still take a long time to biodegrade; depending on
the type of plastic it could be a century or even more!
45
46. POLYMER BLENDED BITUMEN ROADS
• Recent studies in this direction have shown some hope in terms of using
plastic-waste in road construction i.e., Plastic roads. Plastic roads mainly use
plastic carry-bags, disposable cups and PET bottles that are collected from
garbage dumps as an important ingredient of the construction material. When
mixed with hot bitumen, plastics melt to form an oily coat over the aggregate
and the mixture is laid on the road surface like a normal tar road.
46
48. PROCESS-
Cleaned And Dried Plastic Wastes (E.G.: Disposed Carry Bags, Films, Cups And Thermocole) With
A Maximum Thickness Of 60 Microns Is Shredded Into Small Pieces (2.36 Mm - 4.75 Mm Size).
PVC Is Not Suitable For This Process.
Aggregate Is Heated To 165°c In A Mini Hot Mix Plant
Shredded Plastic Is Added To The Hot Mix. The Plastic Gets Softened And Coated Over The
Surface Of The Aggregate Giving An Oily Look In 30 - 60 Sec.
Hot Bitumen (Heated Up To A Maximum Of 160°c To Ensure Good Binding) Is Added Immediately
And The Contents Are Mixed Well.
The Mix, When Cooled To 110 - 120°c Can Be Used For Road Laying Using 8 Ton Capacity Road
Roller. As The Plastics Are Heated To A Maximum Temperature Of 165°C, There Is No Evolution Of
Any Gas. When Heated Above 270°C, The Plastics Get Decomposed And Above 750°C They Get
Burnt To Produce Noxious Gase
48
49. MERITS OF POLYMER BLENDED BITUMEN
ROADS
• STRIPPING AND POTHOLE FORMATION: bitumen film is often stripped off the
aggregates because of the penetration of water, which results in pothole formation. This
is accelerated during the movement of vehicle. When polymer is coated over aggregate,
the coating reduces its affinity for water due to non-wetting nature of the polymer and
this resists the penetration of water. Hence the penetration of water is reduced which
resists stripping and hence no pothole formation takes place on these roads.
• EFFECT OF BLEEDING: waste polymer-bitumen blend shows higher softening
temperature. This increase will reduce the bleeding of bitumen during the summers.
• EFFECT OF FLY ASH: it is also observed that the fly ash does not leach from this
mixture
49
50. INCINERATION
• It is the process of direct burning of wastes in the presence of excess air (oxygen)
at temperatures of about 8000C and above, liberating heat energy, inert gases and
ash.
• BURNING TOXIC GASES &
ASH
800'C-1100'C
50
51. ADVANTAGES OF
INCINERATION
• Incineration Is An Efficient Way To Reduce The Waste Volume
And Demand For Landfill Space.
• Energy Can Be Covered For Heat Or Power Consumption.
51
52. DISADVANTAGES OF
INCINERATION
• AN INCINERATION PLANT INVOLVES HEAVY INVESTMENTS AND HIGH
OPERATING COSTS
• AIR POLLUTION
• GLOBAL WARMING
• DIOXIN AND FURANS
52
53. LANDFILLING
Landfill is the conventional approach to waste management, but space for landfills
is becoming scarce in some countries.
A well-managed landfill site results in limited immediate environmental harm
beyond the impacts of collection and transport, although there are long-term risks
of contamination of soils and groundwater by some additives and breakdown by
products in plastics, which can become persistent organic pollutants.
53
54. PLASMA PYROLYSIS TECHNOLOGY
Plasma pyrolysis is a state of the art technology, which integrates the
thermochemical properties of plasma with the pyrolysis process. The intense
and versatile heat generation capabilities of PPT enable it to dispose off all
types of plastic wastes including polymeric, biomedical and hazardous waste
in a safe and reliable manner.
In plasma pyrolysis, firstly the plastics waste is fed into the primary chamber
at 8500’C through a feeder. The waste material dissociates into carbon
monoxide, hydrogen, methane, higher hydrocarbons etc. Induced draft fan
drains the pyrolysis gases as well as plastics waste into the secondary
chamber, where these gases are combusted in the presence of excess air.
.
54
55. PLASMA PYROLYSIS TECHNOLOGY
• Continued:- The inflammable gases are ignited with high
voltage spark. The secondary chamber temperature is
maintained at around 10500’C. The hydrocarbon, carbon
monoxide and hydrogen are combusted into safe carbon
dioxide and water. The process conditions are maintained so
that it eliminates the possibility of formation of toxic dioxins and
furans molecules (in case of chlorinated waste.
55
56. CO-PROCESSING OF PLASTIC WASTE IN
CEMENT KILN
Co-processing of plastic waste as alternative fuel and raw material (AFR).
Co-processing indicate substitution of primary fuel and raw material by waste.
Waste material such as plastic waste used for co-processing are referred to as
alternative fuels and raw material .
One of the advantage of recovery method used in existing facility is eliminating
the need to invest on other plastic waste practices and to secure land filling.
56
57. CONVERSION OF PLASTICS WASTE INTO LIQUID
FUEL
The entire process is undertaken in closed reactor vessel followed by
condensation, if required.
Waste plastics while heating upto 2700 to 3000’c convert into liquid-vapour
state, which is collected in condensation chamber in the form of liquid fuel.
The tarry liquid waste is topped-down from the heating reactor vessel.
The organic gas is generated which can be used in dual fuel diesel
generator set for generation of electricity.
