Whenever word plastic comes to our mind the first thing that strikes is HARMFUL!
So here is a little presentation to show how to convert that harmful thing into something innovative :)

Plastic pollution is when plastic has gathered in an area and has begun to negatively impact the natural environment and create problems for plants, wildlife, and even the human population.
In total, half of all plastic produced is designed to be used only once — and then thrown away. Plastic waste is now so ubiquitous in the natural environment that scientists have even suggested it could serve as a geological indicator of the Anthropocene era.
Through my PhD at the University of Malta, I wanted to share what I learn with everyone about microplastics in the marine environment (what I do, generalities, techniques).
Beat Plastic Pollution: World Environment Day Aniruddha Guha
This year (2018) India was the host country for official celebrations of WED and escalating the issue of Plastic Pollution for creating required awareness was a matter of utmost importance. This presentation was designed keeping the same in mind. It raised three basic questions,
1) What is the Problem (Problem Definition)?
2) What are the adverse effects of Plastic Pollution?
3) What can we do to stop it?
While answering these questions during the flow of the presentation, the sad reality of Great Pacific Garbage Patch was also discussed. At the final stage, solutions were proposed following 4R concept, namely, Reduce, Reuse, Recycle and Rebuy. The presentation concluded with a small video trailer titled “Albatross” (By Chris Jordan) which exhibited the tragic truth of Midway Island, one the most heart-breaking consequences of plastic pollution.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

4. WHAT IS PLASTIC?
PLASTIC
• Plastics are a wide range of
synthetic or semi-synthetic
materials that use polymers as a
main ingredient.
• Their plasticity makes it
possible for plastics to be
moulded, extruded or pressed
into solid objects of various
shapes and sizes. Plastics
typically are made through
human industrial systems.

5. HISTORY OF PLASTIC
• It was in 1862 that Alexander Parkes introduced
the world’s first ever man-made plastic, at the London
International Exhibition.
• “PARKESINE”, as it was called , was marketed as
an alternative to ivory and horn that Parks discovered
while trying to develop a synthetic substitute for shellac
for waterproofing.
• Though the product was not a commercial success ,
Parkesine represented an important first step in the
development of man-made plastic.
• The material didn’t start to truly show its potential
value and diversity of applications until John Wesley
Hyatt in Albany, New Work discovered a way to
manufacture an improved version of Parkesine, most
commonly known as Celluloid.

TYPES OF PLASTIC
A
There are two main types of plastic they are:-
• Thermoplastics – A thermoplastic is a material,
usually a plastic polymer, which becomes more soft
when heated and hard when cooled. E.g.- Acrylic,
polyester, nylon, polystyrene and Teflon.
• Thermosets–A thermosets polymer, often called a
thermoset, is a polymer that is obtained from
irreversibly hardening by curing from a soft solid or
viscous liquid prepolymer (resin). E.g.- Epoxy Resin,
Phenolic (Bakelite) , Polyester and Cyanate ester.

7. USES OF PLASTIC
• The ability to be moulded makes plastic an ideal
packaging material. Plastics in packaging help to keep
foods safe and fresh.
• Being durable and lightweight , plastics have helped in
the electronic field. From computers and cell phones to
television and microwave , almost all appliances
around us make some use of plastic.
• Plastics are used to make safety gear like helmets ,
goggles etc. Plastics are used in the construction
industry due to their low maintenance and high
durability.
• Plastic is strong and lightweight , that is why useful in
making toys , electrical switches and other household
products. Image source – unsplash.com

8. DISADVANTAGESOFPLASTICS
• Natural decomposition of plastic can last from 400-1000 years
and few types of plastics are non-degradable as well.
• Plastic materials dog waterways, oceans, seas, lakes etc. 1 in 3
species of marine mammals have been found entangled in
marine litter.
• Many animals eat plastic materials and die. Over 90% of all
seabirds have plastic pieces in their stomach.
• Plastic is widely used in packaging. Eating food out of plastic
contains may cause cancer.
• Both creation and recycling of plastic produce toxic gases and
residues which causes air and water and land pollution.
• Plastic cause many fir hazards.
• Disadvantages of plastic bags are well known, this is the reason
why use of plastic bags have been restricted in most of the
countries in the world.

9. POLLUTION
WHAT IS POLLUTION?
• Pollution is the introduction of contaminants into the
natural environment that cause adverse change.
Pollution can take the form of chemical substances or
energy, such as noise, heat, or light .
• Pollutants , the components of pollution,
can be either foreign substances/
energies or naturallyoccurring
contaminants.

10. PLASTIC POLLUTION
WHAT IS PLASTIC POLLUTION?
• Plastic pollution is the accumulation of plastic
objects and particles in the Earth’s
environment that adversely affects wildlife,
wildlife habitat , and humans.
• Plastics that act as pollutants are
categorized into micro-, meso-, or
macro debris, based on size.

5. PLASTIC STRAWS AND STIRRERS.
Globally, more than 8 billion metric tons of plastic have been
produced since its first large - scale use in the 1950s.Plastics take
hundreds of years to degrade. On January 1, 2018 , China stopped
accepting used plastic for recycling because most of the recyclables
were received from countries like USA which were contaminated due
to which it caused many problems in the recycling facilities of China
and threatened its environment. As a result , many governments have
simply ended their recycling programs.
CAUSES OF PLASTIC POLLUTION
11|slide
12. EFFECTS OF PLASTIC POLLUTION
• At least 8 million tons of plastic end up in oceans every year,
and make up 80% of all marine debris from surface water to
deep sea sediments.
• Marine species ingest or are entangled by plastic debris
which causes severe injuries and deaths.
• Plastic Pollution threatens food safety and quality, human
health, coastal tourism, and contributes to climate change.
• Plastic waste clogs drains and in many cities increasing flood
damage.
• Plankton, fish, and ultimately human race, through the food
chain, ingest these highly toxic carcinogens and chemicals.
Consuming the fish that contain these toxins can cause an
increase in cancer, immune disorders, and birth defects.
• Plastic also causes groundwater, air and land pollution.
• Not only animals sea birds are also affected by plastic
pollution. In 2004 it was estimated that gulls in the North Sea
had an average of thirty pieces of plastic in their stomachs.

• 73% of beach litter worldwide is plastic.
• A million plastic bottles are bought around the world
every minute.
• Worldwide, about 2 million plastic bags are used every
minute.

rivers.
• Plastic is killing more than 1.1 million seabirds and
animals every year.
• The average person eats 70,000 microplastics each year.
• The average time that a plastic bag is used for is … 12
minutes.
• Over the past 50 years, would plastic production has
doubled.

14. CASE STUDIES ON PLASTIC POLLUTION
• Galapagos Green Turtle –
➢ Galapagos Green Turtles are found in subtropical waters in the Pacific Ocean and
are the only species of green sea turtle to nest on the beaches of the Galapagos
Islands.
➢ They differ from other marine turtles as they have serrated lower jaw and scales
which cover their eyes, like eyelids.
➢ They can grow to 84cm long and weigh up to 136kg. Galapagos Green Turtles are
extremely fast swimmers, their powerful flippers allow them to travel at speeds up to
35mph.
➢ They mainly feed on molluscs, crustaceans and seaweed, but also eat jellyfish and
fish eggs.
➢ Females return to the same beaches where they hatched to lay their eggs, laying
between 50 and 200 eggs in nests dug out of the sand. After approximately two
months the hatchlings emerge and immediately head for the sea.
➢ Those who make it can take up to twenty years to mature and return to lay their own
eggs. Males can spend their whole lives at sea. They are an endangered species.
➢ Many turtles ingest plastic bags mistaking them for jellyfish, causing fatal blockages
in their guts or starving them because they feel full.
➢ Turtles also face the risk of becoming entangled in plastic debris such as plastic
twine and nylon fishing lines, causing fatal injuries or drowning as they cannot
surface to breath.

15. • Zooplankton –
➢ Zooplankton are organismsdriftingin oceans, seas and bodiesof fresh water.
➢ The word zooplankton comes fromthe Greek zoon, meaninganimal and
planktos, meaning wandererordrifter. Zooplanktonare usuallymicroscopic
–copepods,a type of zooplankton could fit on the head of a pin.
➢ However,some suchas jellyfishare largerandvisibletothe naked eye. They
have hard shells and antennae to sense predators. Some copepodscan
move very quicklythroughthe water at speeds up to one hundred times
faster than Usain Bolt, relative to their size.
➢ Zooplankton are foundin surface waters where food is abundant, they feed
on bacterioplankton, phytoplankton (tiny plants) and other zooplankton as
well as ‘marine snow’(tiny pieces of organic matter including dead
animals). They are foundin abundance across the ocean, their numbers are
affected by water salinity and temperature.
➢ They play a vital role in aquatic food webs as they are eaten by many
higher consumers such as fish. Recent research into copepodshasbeen
investigatingwhetheringestionof microplastics affects the health of these
tiny creatures, which maythenaffectthe carboncycleandwhetherthereare
wider implicationsforanimalsfurtherup the foodchainwhoeat them.
