Title: Recycling Plastics
1Recycling Plastics
- Logan Mongelli, Victoria Pemberton, Roddy
Tierney, Deanna Prue
2Types of Plastics
- There are seven different types of plastics that
are each identified by an identification number
describing chemical makeup
31. PETE- Polyethylene Terephtalate
- The brand name is Dacron
- It is a thermoplastic that is used in synthetic
fibers such as -Beverage, food and other
liquid containers -Thermoforming
applications -Engineering resins often in
combination with glass fiber - Because PETE is an excellent water and moisture
barrier material, plastic bottles made from PETE
are widely used for soft drinks - The majority of the world's PETE production is
for synthetic fibers (more than 60), with bottle
production accounting for around 30 of global
demand - This form of plastic is one of the most commonly
recycled of the seven types - In terms of textile applications, PETE is
referred to by its common name, polyester. The
acronym "PETE" is generally used in relation to
packaging.
4PET consists of polymerized units of the monomer
ethylene terephthalate, with repeating
C10H8O4units.
This is a short piece of the PET polymer chain
52. HDPE- High-density Polyethylene
- HDPE is considered one of the safer plastics and
is easily recycled - It is also stronger than standard Polyethylene,
good barrier from moisture, and stays solid at
room temperature - One other bonus is HDPE doesnt leak any toxic
chemicals into the soil or water - This particular Plastic is known for its strength
to density ratio - Like most plastics it is made from petroleum
- Since this material can be remolded by subsequent
melting and shaping, it is classified as a
polyethylene thermoplastic
6- These are commonly
- used items with the
- Plastics HDPE
73. Vinyl
- Synthetic man-made material made from ethylene
and chlorine - Both the substances are combined to form
Polyvinyl Chloride (PVC) resin - It is the third-most widely produced plastic
- Low cost material to produce, very durable,
resistant to moisture - Used in construction because it is more effective
than traditional materials such as copper, iron
or wood in pipe and profile applications - It is also used in clothing and upholstery,
electrical cable insulation, inflatable products
and many applications in which it replaces rubber
when plasticizers are added to it to make it
softer and more flexible - Easily recycled, and more environmentally
friendly since 57 of vinyl is made from common
salt which is a renewable natural resource
8A strand of the Polyvinyl chloride chain
- About 80 of production involves suspension
polymerization. Emulsion polymerization accounts
for about 12 and bulk polymerization accounts
for 8.
94. LDPE- Low Density Polyethylene
- Thermoplastic made from monomer ethylene
- Started being produced in 1933
- Used in trays, caps/thin lids, six pack
rings,plastic wraps, playground slides. - It can be withstand temperatures of 80 degrees
celsius - Its a very tough plastic but is breakable.
- Unlike PVC, LDPE is not regarded as a bad
plastic -

115. PP- Polypropylene
- Polypropylene is a plastic polymer with the
chemical formula C3H6 - Another thermoplastic polymer that is known for
being rugged and quite resistant to solvents,
bases, and acids - Has a very high melting point of 320 degrees
fahrenheit making it dishwasher safe - Also very easy to add dyes to this type of
plastic - In 2008, the global market for polypropylene had
a volume of 45.1 million metric tons, which led
to a turnover of about 65 billion
12Short segments of polypropylene
136. PS- Polystyrene
- It is a synthetic aromatic polymer made from the
monomer styrene, a liquid petrochemical - Can be rigid or foamed General purpose
polystyrene is clear, hard and brittle - One of the most widely used plastics, the scale
of its production is several billion kilograms
per year - Its uses include protective packaging (such as
packing peanuts and CD and DVD cases),
containers, lids, bottles, trays, tumblers, and
disposable cutlery - Polystyrene foams are good thermal insulators and
are therefore often used as building insulation
materials, such as in insulating concrete forms
and structural insulated panel building systems - It is highly flammable
- It is very slow to biodegrade which is
controversial because it is often abundant as a
form of litter in the outdoor environment,
specifically along shores and waterways
especially in its foam form - Most polystyrene products are currently not
recycled due to the lack of incentive to invest
in the compactors and logistical systems
required. Due to the low density of polystyrene
foam, it is not economical to collect - Foam scrap can be turned into clothes hangers,
park benches, flower pots, toys, rulers, stapler
bodies, seedling containers, picture frames, and
architectural molding from recycled PS
14Polystyrene results when styrene monomers
interconnect. In the polymerization, the
carbon-carbon pi bond (in the vinyl group) is
broken and a new carbon-carbon single (sigma)
bond is formed, attaching another styrene monomer
to the chain.
157. Other- Mixed Plastics
- Generally a wild card marking plastics that dont
fall within the other six categories - Include polycarbonate bottles, which are
understood by scientists to negatively affect
human hormones by leaching bisphenol-A into hot
beverages - Polycarbonate baby bottles are losing favour with
the public, and retailers including are starting
to sell more BPA-free bottles - Some examples of these plastics include
- Silicone-Heat resistant material used mainly as a
sealant but also used for high temperature
cooking utensils - Plastarch materia Biodegradable and heat
resistant, thermoplastic composed of modified
corn starch - Furan- Resin based on Furfuryl Alcohol used in
foundry sands and biologically derived
composites. - Polyimide - A High temperature plastic used in
materials such as Kapton tape

17Advantages 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! - Types Uses- Only two types of plastic,
polyethylene terephthalate (No.1) and
high-density polyethylene (No.2), are recycled at
most locations. - Recycled PET and HDPE can be used to make new
bottles, polyester fibers for use in clothing,
car parts and plastic lumber, among other
products.
18Disadvantages of Recycling Plastic
- Plastic resin, which is part of the manufacturing
and recycling process, and comes from petroleum,
can get into foods stored in recycled plastic
containers - Because of the potential health threats recycled
plastic poses, much plastic recycling is actually
downcycling. This means that the plastic actually
becomes a different, less useful product. - After downcycling, plastic is generally unfit for
another round of recycling. This means that it
ends up in a landfill despite having seen a
secondary use as a less useful product. - The cost associated with processing plastic
categories 3-7 compared with the return available
from a secondary market drives many municipal
recycling programs to deny these items.
19Recycling in Dutchess County
- One positive we have is the Dutchess County
Resource Recovery Agency which is a is a public
benefit corporation created by the New York State
Legislature for the purpose of providing solid
waste management services for Dutchess County. - Local Law NO.1 1984 was the first local law that
provided regulation and authority for dutchess
country to carry out municipal waste
responsibilities - Local Law NO.4 1990 made recycling mandatory for
Dutchess County
20 Mission Statement for D.C.R.R.A.
To dispose of Dutchess County's solid waste in an environmentally friendly way, and where possible, create value in the process.
To promote economically viable recycling in the county.
We will provide and manage the facilities for disposal and recycling.
Where possible we will use private enterprise to accomplish our objectives.
We will endeavor to accomplish our objectives at the least cost to the taxpayer within the constraints of public policy and our charter.
21Recycling in New York State
- NYS Plastic Bag Reduction, Reuse and Recycling
Law increases accessibility to recycle plastic
bags and encourages it - Solid Waste Management Act of 1988 provided a
plan and priorities of waste management in NYS - New York's Bottle Bill - Returnable Container Act
(RCA) - reduced roadside container litter by 70 percent
- recycled 90 billion containers, equal to 6
million tons of materials, at no cost to local
governments - saved more than 52 million barrels of oil and
- eliminated 200,000 metric tons of greenhouse
gases each year. - When the Bottle Bill was passed in 1982
non-carbonated drinks like iced teas, sport
drinks and bottled water made up a small fraction
of the beverage market. Today, non-carbonated
water makes up more than 23 percent of the
market.
22Examples of recycling in NYS
23Recycling in the United States
- Of the 30 million tons of plastic waste generated
in the U.S. in 2009, only 7 percent was recovered
for recycling - EPA regulates household, industrial, and
manufacturing solid and hazardous wastes under
the Resource Conservation and Recovery Act
(RCRA). RCRA's goals are to protect us from the
hazards of waste disposal conserve energy and
natural resources by recycling and recovery
reduce or eliminate waste and clean up waste
that which may have spilled, leaked or been
improperly disposed of - The Solid Waste Program, under RCRA Subtitle D,
encourages states to develop comprehensive plans
to manage nonhazardous industrial solid waste and
municipal solid waste, sets criteria for
municipal solid waste landfills and other solid
waste disposal facilities, and prohibits the open
dumping of solid waste.

25What Can YOU Do?
- Some easy ways to reduce plastic waste include
- Avoid using plastic straws, or purchase a
stainless steel/ glass reusable one - Use reusable bags at the grocery store,
preferably cotton ones - Buy boxes not bottles (laundry detergent, dish
soap, etc.) - Buy in bulk- the less plastic you purchase, the
less you are throwing away - Reuse plastic containers
- Reuse water bottles caps
- Do not use plastic forks, spoons, etc.

27E-Waste Recycling
- By Katerina Economikos, Anna Zoodsma, Jayvon
Johnson, - Rebekah Levine
28What is E-Waste used for? What products? How
many forms are there?
- E-waste describes discarded electrical or
electronic devices. - Product
- Discarded computers
- Office electronic equipment
- Entertainment device electronics
- Mobile phones
- Television sets
- Refrigerators
- ETC..
- The re-usables, (working and repairable
electronics) and secondary scrap (copper, steel,
plastic, etc.) are "commodities". Because loads
of surplus electronics are frequently commingled
(good, recyclable, and non-recyclable), several
public policy advocates apply the term "e-waste"
broadly to all surplus electronics.
29How much is used in the United States?
30What are the current E-Waste recycling rates?
- -Rates are not certain as E-Waste recycling is a
relatively new issue. Materials were not used
frequently until recently. - -U.S. in 2009- 25 electronics recycled
- -38 of computers (18 million)
- -17 of TVs (4.6 million)
- -8 mobile devices (11.7 million)
31How much landfill space could be saved?
- - 1 of landfill space could be saved
- - Between 2003 and 2005, electronic products
available for EOL management were recycled or
disposed of in the following approximate
percentages - About 15-20 were collected for recycling. The
recycled/disposed split remained fairly constant
between 1999-2005. Although recycling continues
to increase, the percentage recycled remains
constant because of the ever-increasing number of
electronics available for EOL management. - About 80-85 were disposed of (largely to
landfills)
32Special Facts
- 80 to 85 percent of electronic products were
discarded in landfills or incinerators, which can
release certain toxics into the air. - E-waste represents 2 percent of America's trash
in landfills, but it equals 70 percent of overall
toxic waste. The extreme amount of lead in
electronics alone causes damage in the central
and peripheral nervous systems, the blood and the
kidneys. - 20 to 50 million metric tons of e-waste are
disposed worldwide every year. - Cell phones and other electronic items contain
high amounts of precious metals like gold or
silver. Americans dump phones containing over 60
million in gold/silver every year. - Only 12.5 percent of e-waste is currently
recycled. - For every 1 million cell phones that are
recycled, 35,274 pounds of copper, 772 pounds of
silver, 75 pounds of gold, and 33 pounds of
palladium can be recovered. - Recycling 1 million laptops saves the energy
equivalent to the electricity used by 3,657 U.S.
homes in a year. - E-waste is still the fastest growing municipal
waste stream in America, according to the EPA. - A large number of what is labeled as "e-waste" is
actually not waste at all, but rather whole
electronic equipment or parts that are readily
marketable for reuse or can be recycled for
materials recovery. - It takes 539 pounds of fossil fuel, 48 pounds of
chemicals, and 1.5 tons of water to manufacture
one computer and monitor
33How much energy could be saved?
- Only 12.5 of e-waste is currently recycled.
- Recycling 1 million laptops saves the energy
equivalent to the electricity used by 3,657 U.S.
homes in a year. - For every 1 million cell phones that are
recycled, 35,274 pounds of copper, 772 pounds of
silver, 75 pounds of gold, and 33 pounds of
palladium can be recovered.
34How is E-Waste typically recycled? What can be
done to make it reusable?
- the product is fixed and resold
- parts of the product that are still useable are
taken out and put in newer models or the same
model that needs it - it is melted down and used for something else
35Why is it important to recycle the E-Waste?
- -E-Waste contains chemicals such as lead,
mercury, cadmium, phosphorus, and flame
retardants (hazardous waste) - -Cathode Ray Tubes (CRTs) are also found in
TV/computer monitors are most harmful to the
environment - -saves landfill space
- -The NYS Electronic Equipment Recycling and
Reuse Act, requires manufacturers to provide free
and convenient recycling of electronic waste to
most consumers in the state.-http//www.dec.ny.go
v/chemical/65583.html
36What are the challenges to recycling the material?
- A serious challenge we are facing is that
refurbishing and reuse of computers and
televisions, while desirable and encouraged, just
delays the ultimate disposal problem. These items
will eventually be unusable, and it will be
important to have programs in place that divert
this waste from landfills. - Finding ways to keep electronic waste out of
landfills is a challenge now facing electronic
equipment manufacturers, recycling and waste
management organizations, elected officials, and
environmental regulatory agencies such as DEQ. At
present, many households have little choice but
to put obsolete or broken electronic items in the
trass have little choice but to put obsolete or
broken electronic items in the trash.
37Is there currently a market for recycled E-Waste?
- A large number of what is labeled as "e-waste" is
actually not waste at all, but rather whole
electronic equipment or parts that are readily
marketable for reuse or can be recycled for
materials recovery. Today the electronic waste
recycling business is in all areas of the
developed world a large and rapidly consolidating
business. Part of this evolution has involved
greater diversion of electronic waste from
energy-intensive downcycling processes (e.g.,
conventional recycling), where equipment is
reverted to a raw material form.
- Examples
- Best Buy Best Buy accepts electronic items for
recycling, even if they were not purchased at
Best Buy. - Staples Staples also accepts electronic items
for recycling at no additional cost. They also
accept ink and printer toner cartridges. - E-Cycling Central is a website from the
Electronic Industry Alliance which allows you to
search for electronic recycling programs in your
state.
38What can recycled E-Waste be made into?
- metal jewelry, automotive parts, electronics,
etc. - plastic new electronic devices, garden
furniture, license plate frames, non-food
containers, replacement automotive parts - battery other rechargeable battery products
39Can E-Waste be reused before it is recycled?
- -Broken E-Waste should either be repaired or
recycled - -if repaired, electronics can be resold or given
back - original owner
- -Much of E-Waste is not broken, customers just
dont want it anymore. With new products coming
out every week, customers are persuaded to buy
newer products even when the old ones are in good
condition.
40What are the disadvantages of recycling the
material?
- -Costly (for certain products)
- -The items associated in recycling e-waste will
eventually be unusable anyway - -Recycling process can produce problems to the
environment (soil/groundwater contamination)
41What would it take to make recycling E-Waste a
more viable operation? Outlook
- Federal Legislative Mandates for Electronics
Recovery At present, there is no Federal mandate
to recycle e-waste. There have been numerous
attempts to develop a Federal law. However, to
date, there is no consensus on a Federal
approach. - State Mandatory Electronics Recovery Programs
Many states have instituted mandatory electronics
recovery programs. - Dutchess County has a mandatory recycling law
(Local Law No. 4 of 1990 and subsequent
amendments) that has been in effect since 1990.

44Recycling Glass
- Ahmöd Tipu, Annika Björnson
- Juli Möngini, Kenny Gödwin
45Glass Recycling
- Americans generate about 11.5 million tons of
glass every year - Only 28 of glass is recycled in the U.S.
- New York recycles more glass compared to most
other states because it has a 5 cent bottle bill
(Its one out of eleven in the U.S. to have such
a bill)
46Glass Uses
- Glass is used for many different products
- Some glass products include
- windows
- bottles jars
- vases
- tiles
- telescopes
- microscopes
47Glass Recycling
- If all of the glass in the United States was
recycled, about 9 million tons of landfill space
would be saved. - Every month, we throw out enough glass bottles to
fill a skyscraper. - Over a ton of resources is saved for every ton of
glass recycled 1,330 pounds of sand, 433 pounds
of soda ash, 433 pounds of limestone, and 151
pounds of feldspar.
48How much energy could be saved by recycling glass?
- According to the EPA, recycling glass only saves
about 30 percent of the energy cost of producing
new glass, and the raw materials required are in
abundant supply. Reusing glass bottles and jars,
however, requires no energy whatsoever, so you
can reduce energy costs by finding new uses for
these containers instead of simply throwing them
out. Once you throw glass out, 1 million years
will pass before that glass breaks down at the
landfill.
49How is glass typically recycled?
- Insulation products
- Ceramic sanitary ware production
- Flux agent in brick manufacture
- Astroturf
- Golf bunker sand
- Recycled glass countertops
- Water filtration media
- Abrasive
- Aggregate
- Glassphalt
50What must be done to make glass reusable?
- To make glass reusable it must be collected and
brought to a separate recycling center then
sorted by colour. After this it is sorted by
color then crushed down to be used in the desired
way the company would like.
51Why is it important to recycle glass?
- The energy saved by recycling just one glass jar
is enough energy to keep a 100 watt glass light
bulb lit for an hour or a home computer running
for 30 minutes.For every ton of glass that has
been recycled, one ton of raw materials can be
saved, including 1,200 pounds of sand, 400 pounds
of soda ash and 360 pounds of limestone.
52Market for Recycled Glass
- Recycled glass containers are always needed by
manufacturers because new glass is needed to meet
demands for more glass containers. - Crushed or pulverized glass can be used the same
way as sand and gravel for parking lots, beaches,
and walking trails. - When recycled glass is used it can help to lower
costs for manufacturers since they would not have
to make new glass for their products.
53Products Made With Recycled Glass
Glass Bottles
Glass Vases
Recycled Glass Countertops
Glass Jewelry
54Uses of Glass Before Recycling
- Before glass is recycled it can be ground up and
used for decorative purposes in gardens or in
place of gravel. - The glass can also be used to replace stones in
asphalt when ground up and therefore used to pave
roads.
Glassphalt
Glass In Gardens
55Problems/Disadvantages with recycling glass
- The glass must be sorted by colour before
recycling. - It would put people out of work in the glass
bottle - manufacturing industry.
- Windows, Pyrex, and other more industrial glasses
cannot be recycled into bottles or anything
because its a different manufacturing process
and if introduced to a container type
manufacturing process, it can cause defective
containers. - It can be and is quite expensive (no exact
figures have been published)
56Outlooks
- Only 11 states have a 5 cent bottle bill, New
York State included. - Dutchess County has a mandatory recycling law for
glass, paper, plastics 1 and 2, and aluminum,
however it is not highly enforced. Due to the
lack of enforcement, many Dutchess County
residents do not recycle. - Ketcham High School does not currently have a
glass recycling system in place either, however
there are a few bins in the Cafeteria that the
custodians are allowed to take the recycled items
from and personally recycle if they so choose.
57Fun Facts! About Glass Recycling
- Glass is 100 recyclable! No other food or
beverage packaging material is! - Recycled glass is substituted for up to 70 of
raw material - Glass can be recycled endlessly without losing
any purity, and is one of very few materials that
can do so - Delaware had repealed their Beverage Container
Regulation law that required a 5-cent deposit on
plastic and glass soft drinks and beer bottles,
and replaced it with a controversial 4-cent
non-refundable recycling fee in 2009 - Glass can take 4,000 years to decompose

59What is the material used for?
- 41 of all paper is used for packaging
- 95 of business information is still stored on
paper - Still used in printing and writing
- Used in construction
60How much is used?
- In the United States Paper makes up for 28 of
all municipal solid waste - Paper waste accounts for 40 of total waste
produced in the U.S each year(71.6 million tons) - Worldwide consumption of paper has risen by 400
in the last 40 years -
61Current Recycling Rates
- In the United States, 66 of all paper used is
recycled. -
62Landfill space saved by recycling
- Recycling one short ton of paper saves three
cubic yards of space in a landfill.
63How much energy can be saved by recycling?
- Recycling one ton of paper saves enough energy
to power the average U.S household for six months
or 4,100 kilowatts per hour.
64Why its important to recycle paper.
- Because paper remains in control of the largest
percent of total solid waste produced in the
United States alone and the fact that the process
that goes into the production of paper and the
acquisition of materials required to make paper
is destructive for many ecosystems.
65Challenges to recycling paper
- Some of the problems facing the issue of
recycling paper are more so related to not the
paper but what goes on it. When recycling paper,
all of the ink, plastic, and wax that was in
contact with or attached to the paper because
many of these materials are poisonous and
detrimental to the recycled paper
66Is there a market for recycled paper
- Approximately 140 paper mills in the U.S use
recycled paper exclusively - There currently is a rise in a strong demand
overseas for U.S recovered paper and an increase
of solid gains in domestic consumption
67What is recycled material made into
- Because many Paper Mills use entirely recovered
paper, almost all paper products contain some
recovered paper
68Economic disadvantages
- The paper recycling industry has made blows to
the lumber industry resulting in some job loss in
the lumber field.
69Pollution
- The EPA has found that recycling causes 35 less
water pollution and 74 less air pollution than
making virgin paper
70Paper vs. Plastic
- Causes air pollution Litter
- Consumes energy Danger to
wildlife - Consumes water Long term
degrading - Inefficient recycling Recycling
difficulties - Produces waste
- Biodegrading difficulties
71ALUMINUM
- By Gayathri Jaikumar, Sabrina Blanke, and David
Emory
72What is aluminum?
- Aluminum is the 2nd most used metal after
- steel (versatile)
- Aluminum industry manufactures 40 billion
- in products each year
- Sustainable metal and can be reused
- Comes from mining bauxite (naturally occurring)
- US generated about 1.9 million tons of aluminum
as containers and packaging. (2011) - 1.6 million tons of aluminum were used to make
durable and nondurable goods (appliances and
automobile parts)
73Aluminum products..
- Aluminum cans are lightweight, convenient,
portable, and keep beverages cold. Used to
package soda, beer, and other beverages, and
account for most of the beverage packaging market
for some products. - Soda Cans
- Baking Tins
- Spray cans
- Foil
- Paper Clips
- Transportation and Parts and License Plates
- Foil Trays
- Pie Pans
- Gum Wrappers
- Electronics
- Curtain Rods
- Roof Siding, Gutters, other Construction pieces
74Recycling Aluminum
- Aluminum is the most recyclable of all materials
it is four times more valuable than other
recycled consumer materials - The US aluminum can recycling rate hit 67 in
2012 (According to data released by the Aluminum
Association, Can Manufacturers Institute (CMI)
and Institute of Scrap Recycling Industries
(ISRI) - The new rate marks progress towards the goal of
75 recycling by 2015
75SAVING ENERGY
- Recycling ONE can of aluminum can save enough
energy to run a TV for 3 hours..OR a 100 watt
bulb for almost a day. - Recycling aluminum cans (on average) can save 10
cubic yards of landfill space. - Throwing away a single aluminum can is like
pouring out six ounces of gasoline
76Recycling Aluminum
- the consumer throws aluminum cans/foil into a
recycling bin - next, it is collected and taken to a treatment
plant - in the treatment plant, it is cleaned for
processing - it goes through a remelt process, turning the
cans/foil into molten aluminum, removing ink that
may still remain - cooled into large blocks called ingots (each
block containing 1.6 million aluminum cans) - ingots are rolled out at mills, which makes the
new aluminum stronger and more flexible - this is then remade into packaging and aluminum
cans - in 6 weeks, the aluminum is ready to go back to
stores and be used again
77Why is it important to recycle aluminum?
- 1. The Hall Process of turning bauxite into
aluminum for cans and foil uses a lot of energy.
In recycling just one aluminum can, you can save
the amount of energy it takes to keep a TV on for
3 hours. - 2. In the Hall Process, current passes through
graphite electrodes submerged in molten aluminum.
When this happens, carbon dioxide is released
into the environment. Recycling aluminum releases
only 5 of this carbon dioxide. - 3. Recycling aluminum requires strip-mining,
where soil upon the site is removed, and that
means that vegetation at the site is destroyed as
well. - 4. Aluminum can be recycled indefinitely its a
valuable commodity!
78Challenges of recycling aluminum
- Recycling aluminum requires a lot of pollution
(electricity and gasoline to transport ore). - There is no funding to look into more
environmentally friendly ways of recycling
aluminum. - Potential for contamination, even if the plant is
sure that they are recycling solely aluminum
products. Even slight impurities can vary the
aluminums properties.
79Recycled Material
- The market for recycled aluminum is growing
rapidly. It is cheaper, faster, and more
efficient to recycle aluminum in todays economy.
It only requires 10 of the capital it took to
make the aluminum to recycle it. - Recycled aluminum can be made into aluminum
drinking cans and aluminum packaging.
80Reducing and Reusing Aluminum
- Eliminate or reduce your aluminum foil use!
- - ONE American throws away about 3 lbs of
aluminum foil each year - - Reuse aluminum foil until it cant be used
anymore (then recycle it) - Dont dispose aluminum pans (reuse them)
- Reduce or find ways to reduce the amount of
aluminum cans used
81Disadvantages to recycling aluminum
- High energy costs in reprocessing and
transporting materials (recycling trucks) - The need to be separated from tin/steel/plastic/ot
her debris - Sorting is time consuming
- When aluminum is continually recycled, it loses
quality - Advantages heavily outweigh the disadvantages
82Advantages to Recycling Aluminum
- Environmental Economic
- - There is no limit to how many times
- Cheap - aluminum can be recycled
-Fast - - Energy efficient
- Generates
jobs in the recycling industry - -Saves precious resources
- Saves time - - Recycling aluminum saves 90-95 percent of
- Helps to pay for community service
projects - the energy needed to make aluminum from
(Aluminum industry pays a billion dollars
for - bauxite ore.
recycled aluminum
cans- the money supports
organizations like
Habitat For Humanity and local -
schools/churches that sponsor
aluminum recycling programs)
83OUTLOOK
- The Dutchess County Mandatory Source Separation
Law was passed in 1990 - -This includes recycling aluminum food/drink cans
and aluminum foil products - Local centers (ex. Mid-Hudson Aluminum Cans
Recycling, INC.) - Recycling rates are increasing in the statewide
(NY) and nationally. (both econ. and enviro.
viable)
84FACTS ABOUT ALUMINUM
- Discovered in the 1820s, aluminum is the most
abundant metal - An average of 113,204 aluminum cans are recycled
every minute. - 20 recycled cans can be made with the energy
needed to produce 1 can using virgin ore - Throwing away an aluminum can wasted as much
energy as pouring out half of that cans volume of
gasoline - Making new aluminum cans from used cans takes 95
less energy than using virgin materials - Increasing the rate of recycling of aluminum

a month), pays for itself, and is great for the
environment.
