19. How long does plastic take
to decompose????
F.Y.I. Plastics
do not
decompose!!!!
NEVER!
20. It only breaks down into
molecules.
Molecules that are
harmful to the
environment.
21. Plastics are
believed not to
decompose but only
photo degrade.
22. Decomposition vs. Photo
Degradation
Decomposition is “the
chemical breakdown of
organic matter into its
constituents by the action of
bacteria,” while photo
degradation is, “the process
by which chemical bonds are
broken down by photons in
the sun’s light spectrum.”
24. A very long long long
time…….
In a way that it is being
estimated up to
hundreds…..thousands
of… years.. depends
upon its composition..
25. Types of Plastic:
Plastic #1: Polyethylene
terephtalate, also known as
PETE or PET. Usually clear
in color, the vast majority of
disposable soda and water
bottles are made of this
plastic. Range from 5 to 10
years.
26. Types of Plastic:
Plastic #2: High-density
polyethylene, or HDPE.
Most milk jugs, detergent
bottles, juice bottles, butter
tubs, and toiletries bottles
are made of HDPE. It takes
100 years depending on the
thickness of the plastic used.
27. Types of Plastic:
Plastic #3: Polyvinyl
chloride, or PVC. It is used
to make food wrap, bottles
for cooking oil, and the
highly common plumbing
pipes.
28. Types of Plastic:
Plastic #4: Low-density
polyethylene (LDPE) is used
to make grocery bags, some
food wraps, squeezable
bottles, and bread bags. 500
years with a conservative
average time of 1000 years.
29. Types of Plastic:
Plastic #5: This is
polypropylene. Common items
produced with it include yogurt
cups, medicine bottles,
ketchup, syrup bottles, straws
and similar wide-necked
containers, as well as water
bottles with a cloudy finish.
30. Types of Plastic:
Plastic #6: Polystyrene, or
Styrofoam, from which
disposable containers and
packaging are made. Also
found in disposable plates and
cups. This type of plastic will
break down in under 50 years.
31. Types of Plastic:
Plastic #7: Other Types
- This includes anything not
in codes one through six.
Most plastics in this section
do not breakdown and are
considered permanently,
chemically bonded.
39. Chemicals used in the
production are highly toxic
& pose serious treat to
living beings of all
species.. It can cause
cancer, skin & respiratory
problems……
40. And it may causes...caused…
will cause…..
FLOODS!!!
61. RECYCLE
When waste is eventually
discarded, segregating
items for recycling from
other waste is important.
Recyclables include
glass, newspaper,
aluminum, cardboard and
a surprising array of other
materials.
