Plastic and Plastic Pollution
• A plastic material is any of a wide range of synthetic or semi-
synthetic organic solids that are moldable. Plastics are typically
organic polymers of high molecular mass, but they often
contain other substances. They are usually synthetic, most
commonly derived from petrochemicals.
• Plastic pollution is accumulation of plastic products in the
environment that adversely affects wildlife, wildlife habitat, or
humans. Many types and forms of plastic pollution exist.
Plastic pollution can adversely affect lands, waterways and
oceans. Plastic reduction efforts have occurred in some areas
in attempts to reduce plastic consumption and promote plastic
recycling. The prominence of plastic pollution is correlated
with plastics being inexpensive and durable, which lends to
high levels of plastics used by humans.

Plastic Recycling is the process of recovering scrap or
waste plastic and reprocessing the material into useful
products, sometimes completely different in form from
their original state.
For e.g. melting down soft drink bottles and then casting
them as plastic chairs and tables.
Plastic 'recycling' is largely a misnomer since plastic
beverage bottles (soda, juice, milk) are never reformed
into new beverage bottles; this requires virgin plastic.
There simply is no cycle involved with the "recycling" of
plastic beverage containers.

Plastics are also recycled/reprocessed during the
manufacturing process of plastic goods such as
polyethylene film and bags. A percentage of the recycled
pellets are then re-introduced into the main production
operation. This closed-loop operation has taken place
since 1970s and has made the production of some plastic
products amongst the most efficient operations today.

Recycling of Plastics
• Recycling of plastics that used to end up only at
city landfills or incinerators is increasing around the world.
• As with any technological trend, the engineering profession plays
an important role.
• Discarded plastic products and packaging make up a growing
portion of Municipal Solid Waste (MSW).
• The Environmental Protection Agency (EPA) estimates that by the
year 2000, the amount of plastics throw away was 50 percent
greater than at the beginning of the 1990s.
• EPA also says that plastic waste accounts for about one-fifth of all
waste in the waste stream.
• Over the past two decades, recycling of plastics has dramatically
increased. After years of predictions that plastics recycling would
never be widespread because processes were inefficient, too
expensive or not practical, the tide of waste headed to the landfill
is slowly being turned.

HOW IS PLASTIC RECYCLED
1. Plastic bottles are collected either by kerbside collection, or
from plastic bottle banks, and taken to a material reclamation
facility (MRF) where they are sorted into their different types –
HDPE, PET and PVC. Sorting the bottles

2. Once sorted, the bottles are squashed into tightly packed
blocks or bales. Squashing the plastic bottles saves energy
because you can get more on a lorry when transporting
them than if they weren't squashed.

• 3. The bottles are then taken to a reprocessing factory
where the bottles are cut up into small flakes – about the
size of corn flakes. The flakes are washed to remove any
dirt and labels and then they are dried.
• 4. The clean plastic flakes are then sent to factories where
they are melted down and made into new items. Recycled
plastic bottles can make all sorts of new things including
new bottles, fleece clothes, garden furniture, kerbside
collection boxes, drain pipes and much more.

What plastics are not accepted
 No plastic bags
Plastic bags are by far the WORST contaminant in the
recycling bin. Please do not put plastic bags in your bin and
please do not bag any materials. Clean, dry and empty
plastic bags with #2 or #4 can be recycled at the Charm or
at particupating grocery stores.
 No Foam
While white foam cups and containers often have a #6 on
the bottom, they are not a recyclable plastic.
These products can be easily avoided for their safer, reusable
or recyclable counterparts.

• No #7 PLA bottles or containers
• It couldn’t be as simple as ALL #1 - 7 plastics, could it? The
broad #7 category was designed as a catch-all for
polycarbonate (PC) and “other” plastics.
• Unfortunately, new compostable plastics, made from bio-
based polymers like corn starch, are also thrown into this
category and labeled with a #7. But, you can tell them apart
from their petroleum-based relatives because compostable
plastics Also have the initials PLA on the bottom near the

Challanges
• Compared with other materials, such as glass and metal, plastic
polymers require greater processing like heat treating,
thermal depolymerization and monomer recycling to
recycle. Due to the high molecular weight of their large
polymer chains, plastics have a low entropy of mixing. A macro
molecule interacts with its environment along its entire length,
so total energy involved in mixing it is largely due to the
product side stoichiometry. Heating alone is not enough to
dissolve such a large molecule, so plastics must often be of
nearly identical composition to mix efficiently.
• When different types of plastics are melted together, they tend
to phase-separate, like oil and water, and set in these layers.
The phase boundaries cause structural weakness in the
resulting material, meaning that polymer blends are useful in
only limited applications.

• Another barrier to recycling is the widespread use of dyes,
fillers, and other additives in plastics. The polymer is generally
too viscous to economically remove fillers, and would be
damaged by many of the processes that could cheaply remove
the added dyes. Additives are less widely used in beverage
containers and plastic bags, allowing them to be recycled
more often.
• Yet another barrier to removing large quantities of plastic
from the waste stream and landfills is the fact that many
common but small plastic items lack the universal triangle
recycling symbol and accompanying number. An example is
the billions of plastic utensils commonly distributed at fast
food restaurants or sold for use at picnics.
• The use of biodegradable plastics is increasing.

Processes
• Before recycling, most plastics are sorted according to their
resin type. In the past, plastic reclaimers used the resin
identification code (RIC), a method of categorization of
polymer types, which was developed by the Society of the
Plastics Industry in 1988. Polyethylene terephthalate,
commonly referred to as PET, for instance, has a resin code
of 1. Most plastic reclaimers do not rely on the RIC now;
they use automatic sort systems to identify the resin, such as
near infrared (NIR) technology. Some plastic products are
also separated by color before they are recycled. The plastic
recyclables are then shredded. These shredded fragments
then undergo processes to eliminate impurities like paper
labels. This material is melted and often extrudedinto the
form of pellets which are then used to manufacture other
products.

Thermal depolymerization
• Another process involves the conversion of assorted
polymers into petroleum by a much less precise thermal
depolymerization process.
• Such a process would be able to accept almost any
polymer or mix of polymers, including thermoset
materials such as vulcanized rubber [[tire] superation of
waste]s and the biopolymers in feathers and other
agricultural waste.
• Like natural petroleum, the chemicals produced can be
made into fuels as well as polymers. A pilot plant of this
type exists in carthage, Missouri, United States, using
turkey waste as input material. Gasification is a similar
process, but is not technically recycling, since polymers
are not likely to become the result.

• Yet another process that is gaining ground with startup
companies (especially in Australia, United States and Japan) is
heat compression. The heat compression process takes all
unsorted, cleaned plastic in all forms, from soft plastic bags
to hard industrial waste, and mixes the load in tumblers (large
rotating drums resembling giant clothes dryers). The most
obvious benefit to this method is the fact that all plastic is
recyclable, not just matching forms. However, criticism rises
from the energy costs of rotating the drums, and heating the
post-melt pipes.
Other processes
• A process has also been developed in which many kinds of
plastic can be used as a carbon source in the recycling of
scrap steel.

10 simple things we can do to help reduce the
amount of plastic we use every year
• Stop using bottled water – In most cases it is no safer
than tap water and costs 3 times as much gasoline and
1,ooo times as much as tap water
• Bring your own reusable grocery bags with you when you
go to the store
• Use a refillable dispenser for your hand soap and dish
washing liquid, one large bottle is better than using a
bunch of small ones
• Use a reusable container instead of sandwich bags
• Bring your own to-go mug with you to the coffee shop
• Say no to single serving packaging, buy in bulk and share
with friends instead
