Plastic is all around us. It forms much of the packaging for our food and drink. For many of us, it is throughout our home, our workplace, our car, the bus we take to and from work. It can be in our clothing, eyeglasses, teeth, toothbrush, computers, phones, dishes, utensils, toys. The list goes on, especially when you look around and begin to notice the plastic in your life.
Plastic is versatile, lightweight, flexible, moisture resistant, durable, strong and relatively inexpensive. It can be chemical resistant, clear or opaque, and practically unbreakable. These are wonderful useful qualities, and plastic plays many important roles in life on Earth, but the widespread use of plastic is also causing unprecedented environmental problems, and harbours serious health risks . Plastic should be used wisely, with caution and only when suitable alternatives do not exist or are not available.

Easy understanding of effects of plastic on the environmentAugustine Okoth
Plastic pollution and the effects it has on the environment. This slide makes it easier to explain to children and adults too on the effects of plastics pollution.
This ppt describes the usage of plastics and its management
Though plastics has huge applications, it has various harm fullness. So we need to find methods to manage plastic waste.
Today plastic disposal is the major problem faced by the world,so in order to curb that pollution, it is our responsibility to use less plastics and recycle it.
SUSTAINABLE PACKAGING
Packaging protects and promotes food, beverage, and consumer products across the globe. Packaging is expected to grow at an average rate of 3.4% over the next decade (according to Smithers Pira), and most producers of consumer goods are seeking ways to enhance their sustainability initiatives. This presentation will cover trends in sustainable packaging, and how adhesives can enhance and enable your package designs.

This was created by fact checking a famous internet chain mail describing the horrors of plastic bags. It appears that most of it was never really linked to any authoritative source. But news papers like the NY times a Boston Globe as fact. It is truely an example of Escience and Ejournalism where research is conducted online and professional standards of fact checking and documentation were abandoned
Hi i'am Sean , i study in OUR OWN ENGLISH HIGH SCHOOL .This is a power point on plastics , to help us understand what is a plastic , what are the types of plastic and what harm do they cause to our environment
Plastic waste management- Conventional and New Technologyrmeena99
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.
It is based on how we are polluting the environment with so much of plastic and it causes many types of pollution. It is the PowerPoint Presentation. So you all can make the best PowerPoint Presentation by my ideas. It is my Believe
Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans.[1] Plastics that act as pollutants are categorized into micro-, meso-, or macrodebris, based on size.[2] The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans.[3] However, it is slow to degrade.[4] Plastic pollution can unfavorably affect lands, waterways and oceans. Living organisms, particularly marine animals, can also be affected through entanglement, direct ingestion of plastic waste, or through exposure to chemicals within plastics that cause interruptions in biological functions. Humans are also affected by plastic pollution, such as through the disruption of the thyroid hormone axis or hormone levels. In the UK alone, more than 5 million tonnes of plastic are consumed each year, of which an estimated mere 24% makes it into recycling systems. That leaves a remaining 3.8 million tonnes of waste, destined for landfills.[5][6] Plastic reduction efforts have occurred in some areas in attempts to reduce plastic consumption and pollution and promote plastic recycling.
4. The word plastic is derived from the Greek (plastikos)
meaning capable of being shaped or molded.
Plastics are a range of synthetic or semi-synthetic polymerization
products that can be molded into a permanent object having the
property of plasticity.
Plastic is a long chain like molecules(Polymars) made from
petroleum capable being molded, extruded or cast into various
shapes.
The first plastic was invented in 1862 by Alexander Parkes.
At first plastics could only be made in brown or black (Bakelite)
color.
In 1930’s “Amino plastics' "had been invented which could be
made in lots of bright color.
About plastics….
5. A plastic bottle is a rigid or semi-rigid container composed of plastic,
having a comparatively narrow neck or mouth but without any handle.
There is an opening on the top of the bottle which is fastened by a
cap.
Plastic bottles are primarily used for storing liquids like water, milk,
cooking oil, medicine, and soft drinks.
Plastic soda bottles first arrived in the market in the beginning of the
1970s, almost 200 years later than the discovery of plastic.
In the past, plastics were derived from nature. It was not until the
1900s that the production of purely synthetic plastic has begun.

6. About 100 million tones of plastic is produced each year.
Properties of Plastics
Resistant Durable Insulator Inexpensive
Easy to
produce
• Plastics are strong, light weight, flexible and durable.
• Plastics show superior optical properties(clarity, gloss and color).
• Plastics can be easily molded into a variety of shapes and sizes.
• Plastics have excellent mechanical strength (tensile properties, tear
resistance impact resistance).
9. Classification
80% of the plastics produced are thermoplastics and of these Polyethylene, Polypropylene,
Polystyrene and Polyvinylchoride (PVC) are most commonly used (70%)
Thermoplastic
Thermosetting
• Plastics that do not undergo chemical
change in their composition when heated
and can be molded again and again.
• Thermosets are permanently "set" once
they're initially formed and can't be melted.

13. Plastics those are Food Graded or not
Standards for materials used in food applications may be determined by compliance agencies such as Health Canada or the United
States Food and Drug Administration (FDA or USFDA) where there are no regulations, standards setting organizations such as NSF
International and the American National Standards Institute have developed voluntary standards that are widely accepted
throughout the world.
Food Grade Material Criteria
appropriate for intended use; suitable for the
activity being conducted and the environment in
which it is being conducted
non-toxic; surfaces and coatings are free of lead
solder, lead, and/or lead-containing alloys or other
toxic components likely to contaminate food
non-porous/non-absorbent; to prevent
contaminants such as chemical residues, mould
spores, etc. being trapped/absorbed/transferred to
sap or syrup
smooth; surfaces are free from pitting, cracks,
crevices, open seams, holes, corrosion, loose scale,
peeling paint, etc.
corrosion resistant in the intended end use
environment
Food Grade Material Criteria
inert; does not chemically react with, or
leach into maple products, does not react
with cleaning chemicals, etc.
durable; able to withstand repeated
cleaning and sanitizing without surface
degradation
cleanable; does not harbour bacteria or
cleaning and/or sanitizing chemicals
non-breakable; will not create a physical
hazard
kept in good repair and properly
maintained
14. Plastics those are Food Graded or not
Food Grade Materials
Stainless steel (as determined by NSF/ANSI 51, requires a minimum 16% chromium which includes SAE series
200, 300 or 400 series - 300 series is most commonly used in the food industry)
Plastic recognized as food grade (meets compositional and purity standards, as well as established conditions of
use, determined by a compliance agency e.g. Health Canada)
Aluminum (as determined by NSF/ANSI 51, only Alloy Series 1000, 3000, 4000, 5000 and 6000 may be used. Its
use is generally limited to sap buckets and 6000 series aluminum filter presses)
Glass (as determined by NSF/ANSI 51, if not subjected to impact by hard objects during use)
Filter fabric (meets voluntary national standards established by NSF/ANSI 42 & 53)
Reverse Osmosis membrane (meets voluntary national standards established by NSF/ANSI 58)
Diatomaceous earth (meets standards determined by a compliance agency e.g. Health Canada)
Plastic piping and/or tubing (meets standards of NSF/ANSI 51 for food equipment materials
Plastic tubing suitable for potable water (designated as NSF/ANSI 61 or NSF-PW)
15. Plastics those are Food Graded or not
Non-Food Grade Materials
Terneplate (a tin/lead alloy coating with up to 85 percent lead)
Lead solder (a tin/lead alloy - may contain up to 60 percent lead)
Non-food grade plastic (chemical composition and/or material purity not deemed acceptable
by a compliance agency e.g. Health Canada)
Galvanized steel (a pure zinc coating) often associated with lead soldered seams in older
equipment, utensils and valves; standards set by the Manufacturers of Maple Sugaring
Equipment do not permit the use of galvanizing on any food contact surface
Painted steel (may contain lead, peeling probable)
Brass (a copper/zinc alloy) depending on its composition, may contain small quantities of
antimony, arsenic, phosphorus, manganese, silicon and up to 3.8 percent lead to improve
machinability - lead-free brass may be used only for connections and joints.
17. POLLUTANTS FROM PLASTIC
Plastics Release Pollutants:
•Poly brominated di-phenyl ethers (PBDE)
•Nonylphenolls
•Bisphenol A (BPA)
•Phthalates
Plastics Absorb Hydrophobic Pollutants:
•Polychlorinated biphenyls (PCBs)
•Dichloro Diphenyl Trichloro ethane (DDT)
•Dichloro Diphenyl Dichloro ethylene (DDE)
PVC when burned result in emissions of the deadly poisons named dioxin.
Dioxins are highly persistent compounds, with the potential to become increasingly
concentrated in living tissues as they move up the food chain. It is often considered to be the
man-made compound most toxic to animals.
18. Pollution due to plastic bottles & containers
Bisphenol –A & Phthalates
Food and drinks stored in plastic bottles can contain trace amount of Bisphenol
A (BPA), a synthetic chemical that interferes with the body’s natural hormonal
messaging system.
Repeated re-use of such bottles—which get dinged up through normal wear
and tear and while being washed—increases the chance that chemicals will leak
out of the tiny cracks and crevices that develop over time.
BPA has been linked to breast and uterine cancer, an increased risk of
miscarriage, and decreased testosterone levels.
A tin can that entered the ocean in 1986 is still decomposing in 2006 but a
plastic bottle that entered the ocean in 1986 is decomposing in 2436.
19. Pollution due to plastic bottles & containers
Bisphenol –A & Phthalates
These chemicals are both shown to be potent hormone
disruptors and are increasingly linked to adverse health effects
like cancer, infertility, early puberty, obesity, behavior changes,
and reproductive system damages.
A landmark report on BPA published in 2008 by the U.S. National
Toxicology Program concluded that there were concerns over
BPA’s effects on the brain, behaviour and prostate gland
development in foetuses, infants and children.
meaning “one-time use”. So don't reuse single-use plastics.
They can break down and release chemicals into your food or
beverage when used repeatedly..
A study has for the first time linked a common chemical used in
everyday products such as plastic drink containers and baby
bottles to health problems, specifically heart disease and
diabetes.
20. Impact on Environment
Plastic is ever-present in our lives because it is
convenient and relatively inexpensive.
Its convenience comes from being lightweight and its
ability to absorb impact shock without breaking.
Plastics are so versatile in use that their impacts on
environment are extremely wide ranging, posing serious
challenge for disposal.
Careless disposal of plastic bags chokes drains, blocks the porosity of the soil, and causes
problems for groundwater recharge. Due to its non-biodegradable nature, littering of plastics
causes irreversible damage to the environment.
21. Disadvantages of Plastic Products
As many as 100,000 whales, turtles
and birds have been reported to die
every year, because of plastic in
environment.
Plastic not only have adverse effects
on our natural habitats, but have also
been found to be responsible for the
death of many animals, mainly on
account of the suffocation
encountered on eating them.
22. When plastic burned in
air it releases a host of
poisonous chemicals into
the air, including dioxin,
the most toxic substance
known to science.
Plastic when burn in air
1. Dioxins are found throughout the world in the environment and
they accumulate in the food chain, mainly in the fatty tissue of
animals.
2. Dioxins are highly toxic and can cause reproductive and
developmental problems, damage the immune system, interfere
with hormones and also cause cancer.
23. Some recommendation for using plastics
Don't microwave in plastic containers.
Cover food in the microwave with a paper towel instead of plastic
wrap.
Don't reuse single-use plastics (the number one – PET plastics). They
can break down and release plastics chemicals when used repeatedly.
Do not use old, scratched plastic containers. Exposures to plastics
chemicals may be greater when the surface is worn down.
Choose glass or BPA-free baby bottles with a clear silicone nipple.
Avoid plastic to mouth contact, especially for babies and kids.
