Title: Recycling Plastics

Recycling Plastics
  • Logan Mongelli, Victoria Pemberton, Roddy
    Tierney, Deanna Prue

Types of Plastics
  • There are seven different types of plastics that
    are each identified by an identification number
    describing chemical makeup

1. 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
  • 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

PET consists of polymerized units of the monomer
ethylene terephthalate, with repeating
This is a short piece of the PET polymer chain
2. 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

  • These are commonly
  • used items with the
  • Plastics HDPE

3. 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

A 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.

4. 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
  • Its a very tough plastic but is breakable.
  • Unlike PVC, LDPE is not regarded as a bad

5. 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
  • 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

Short segments of polypropylene
6. 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

Polystyrene 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.
7. 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
  • 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
  • Polyimide - A High temperature plastic used in
    materials such as Kapton tape

Advantages 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
  • 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
  • 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

Disadvantages 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
  • 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.

Recycling 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
  • Local Law NO.4 1990 made recycling mandatory for
    Dutchess County

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.
Recycling 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
  • reduced roadside container litter by 70 percent
  • recycled 90 billion containers, equal to 6
    million tons of materials, at no cost to local
  • 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

Examples of recycling in NYS
Recycling 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.

What 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.

E-Waste Recycling
  • By Katerina Economikos, Anna Zoodsma, Jayvon
  • Rebekah Levine

What 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.

How much is used in the United States?
  • 2.37 million short tons

What 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)

How 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
  • 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

Special 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
  • 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
  • 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

How 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.

How 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

Why 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
  • -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

What 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.

Is 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

What can recycled E-Waste be made into?
  • metal jewelry, automotive parts, electronics,
  • plastic new electronic devices, garden
    furniture, license plate frames, non-food
    containers, replacement automotive parts
  • battery other rechargeable battery products

Can E-Waste be reused before it is recycled?
  • -Broken E-Waste should either be repaired or
  • -if repaired, electronics can be resold or given
  • 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

What are the disadvantages of recycling the
  • -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)

What 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
  • 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.

Recycling Glass
  • Ahmöd Tipu, Annika Björnson
  • Juli Möngini, Kenny Gödwin

Glass 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)

Glass Uses
  • Glass is used for many different products
  • Some glass products include
  • windows
  • bottles jars
  • vases
  • tiles
  • telescopes
  • microscopes

Glass 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.

How 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

How 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

What 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.

Why 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.

Market 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.

Products Made With Recycled Glass
Glass Bottles
Glass Vases
Recycled Glass Countertops
Glass Jewelry
Uses 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

Glass In Gardens
Problems/Disadvantages with recycling glass
  • The glass must be sorted by colour before
  • It would put people out of work in the glass
  • 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
  • It can be and is quite expensive (no exact
    figures have been published)

  • 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.

Fun 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

What is the material used for?
  • 41 of all paper is used for packaging
  • 95 of business information is still stored on
  • Still used in printing and writing
  • Used in construction

How 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

Current Recycling Rates
  • In the United States, 66 of all paper used is

Landfill space saved by recycling
  • Recycling one short ton of paper saves three
    cubic yards of space in a landfill.

How 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.

Why 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.

Challenges 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

Is 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

What is recycled material made into
  • Because many Paper Mills use entirely recovered
    paper, almost all paper products contain some
    recovered paper

Economic disadvantages
  • The paper recycling industry has made blows to
    the lumber industry resulting in some job loss in
    the lumber field.

  • The EPA has found that recycling causes 35 less
    water pollution and 74 less air pollution than
    making virgin paper

Paper vs. Plastic
  • Causes air pollution Litter
  • Consumes energy Danger to
  • Consumes water Long term
  • Inefficient recycling Recycling
  • Produces waste
  • Biodegrading difficulties

  • By Gayathri Jaikumar, Sabrina Blanke, and David

What 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)

Aluminum 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

Recycling 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
  • The new rate marks progress towards the goal of
    75 recycling by 2015

  • 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

Recycling Aluminum
  • the consumer throws aluminum cans/foil into a
    recycling bin
  • next, it is collected and taken to a treatment
  • in the treatment plant, it is cleaned for
  • 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
  • in 6 weeks, the aluminum is ready to go back to
    stores and be used again

Why 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
  • 4. Aluminum can be recycled indefinitely its a
    valuable commodity!

Challenges 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
  • Potential for contamination, even if the plant is
    sure that they are recycling solely aluminum
    products. Even slight impurities can vary the
    aluminums properties.

Recycled 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.

Reducing 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

Disadvantages 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
  • Advantages heavily outweigh the disadvantages

Advantages to Recycling Aluminum
  • Environmental Economic
  • - There is no limit to how many times
    - Cheap
  • aluminum can be recycled
  • - 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
  • the energy needed to make aluminum from
    (Aluminum industry pays a billion dollars
  • bauxite ore.
    recycled aluminum
    cans- the money supports

    organizations like
    Habitat For Humanity and local

  • schools/churches that sponsor
    aluminum recycling programs)

  • 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.

  • 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
  • Making new aluminum cans from used cans takes 95
    less energy than using virgin materials
  • Increasing the rate of recycling of aluminum
    could cut a million tons of pollutants per year
    out of the atmosphere (making/burning aluminum is
    a dirty process)
  • Recycling aluminum is fast (back on the shelf in
    a month), pays for itself, and is great for the
