Recycling
By: Leah HinshawMarianne Cruzat
and Kaylee Llewellyn
Recycling• Recycling is the act of processing used or abandoned
materials for use in creating new products.• Recycling is commonly mispercieved.• There are a number of benefits, as well as drawbacks. • Is recycling really worth the hassle?
Pros and Cons of RecyclingPros
• "Green" • Saves money• Will keep environment
healthy• Can reuse many of the
materials again• Feel great by knowing
you are helping the environment
Cons• Planning• Costly• Encouragement• Time Consuming• Pollution by factories
Pictures
The pictures above are results of not recycling and putting trash in landfills.
Facts and General Statistics• A trash truck holds approximately 37 cubic yards of trash.• An average family garbage can is about 0.27 yards by 0.416 yards
by 0.75 yards. This is 0.087 cubic yards.• The average person produces about ¼ of a trash can worth of trash a
week. This means that each person must produce about 0.02175 cubic yards of trash per week.
• 426 trash cans fit into one trash truck. • 275 trash trucks would be needed to dump all of the trash produced by
Winston-Salem residents.• Winston-Salem produes 10,132.1 cubic yards of trash per week• The city is paying around $27,500 per week in landfill costs
Savings of a Family• Our family (4 people) generate about 21 lbs of garbage in an average week and
around 3 pounds per day. We recycle around 1/2 of the garbage we produce and usually have more recycling than we do garbage. That would be around 10 pounds of recyclable material in a week.Glass/plastic = .75 lbs; Paper/metal = 1.25 lbs; Miscellaneous = 1 lb (per day)
• The volume of garbage produced in a week is: 0.173 cubic yards of garbage uncompressed. About ½ of the garbage is recyclable material and we don’t compress our garbage. The volume of recyclable material is around 0.087 cubic feet of material per week.Our trash can is 10 x 15 x 27 inches and there is one for trash, one for recycling, each one fills once a week.
• The city would save $9,500 a week by recycling if 1/3 of the materials being put in a landfill are recyclable material. Imagine what it would be if we recycled more!
Value of Recyclable Materials
• Metal on average is worth around $0.75 per pound• Plastic/Glass is worth around $0.10 per pound• Paper is worth $20.00 per ton• *If recycling is not separated, it will cost the city an
additional $0.03 per pound to have it separated • An average family produces 10 pounds of recyclable
material in one week• 5.25 lbs. in glass/plastic• 8.75 lbs. in metal• 0.5 lbs. in paper

Statistics on Recycling PaperEvery recycled ton of paper saves 17 trees, 275 pounds of sulfur, 350 pounds of limestone, 9,000 pounds of steam, 60,000 gallons of water, 225 kilowatt hours, and 3.3 cubic yards of landfill space.
Recycling 14 trees worth of paper reduces air pollutants by 165,142 tons.
The energy used to recycle paper is close to 70% less than when paper is prepared using virgin wood and other raw material.
Statistics on Recycled PlasticAlmost every hour, nearly 250,000 plastic bottles are dumped. It is not surprising that plastic bottles constitute close to 50% of recyclable waste in the dumps.
The average time taken by plastic bottles to decompose in a landfill is close to 700 years.
Used plastic dumped into the sea kills and destroys sea life at an estimated 1,000,000 sea creatures per year!
Statistics on Metal
Four pounds of bauxite can be saved with every pound of aluminum recycled.
Every day, about 133 square miles of aluminum is used to wrap hershey kisses.
Aluminum is one of the easiest and fastest materials to recycle. Aluminum cans can be recycled and reused within 60 days.
Statistics on Electronics and Technology
Americans own approximately 24 electronic products per household.
A typical computer monitor with a cathode ray tube display contains 2-4 kilograms of lead, as well as phosphor, barium, and hexavalent chromium.
Of the 2.25 million tons of TVs, cell phones and computer products,18% (414,000 tons) are collected for recycling and 82% (1.84 million tons) was disposed of, primarily in landfills.
About 25 million TVs are taken out of service yearly.
Ways to Cut down E-Waste (Waste from Electronics)
• Many cell phone manufacturers and service providers will take back used phones for reuse or recycling.
• When buying an electronic, choose a product that has all the features you will need for the future
• Purchase used or refurbished electronics• Before buying replacement equipment, check on what you
need to replace and make the best choice• Before throwing electronics away, check if anyone might
need the parts from it• Donate the electronic to local schools, organizations,
etc..They are always willing to take things in

I only feel angry when I see waste. When I see people throwing away things wecould use.-- Mother Teresa
• Old MP3 players, Televisions, Cell phones, Computers, Cars and more
• Dismembered and Seperated• Reuse or properly dispose of• Less trash• Saves money for city as well as companies
Return• Encourage using incentive• $0.05 per can or bottle• $5 per mp3/cell phone• $10 per computer• $100 per car• New Technology Tax
Advertise
• Start many programs that increase awareness• Start an advertisement company that will explain the
benefits and simplicity of recycling• Be sure to include children and teens by going to
schools• Can start "competitions" within the school. Whatever
class has the most recyled material wins.• Hold seminars or conventions that emphasize on the
simplicity of recycling and all the benefits that will come out of it.
Separate
• Return program will encourage separation• Positive attitude• Incentive for recycling• Fine for not recycling
*Information about how material is recycled on next slides
Metals and Paper • Paper is usually seperated by
passing it over a large mesh screen so that smaller items fall through the large holes.
• Steel is seperated using electro-magnets.
• Other metals are seperated using Eddy Currents.
• Electronics are taken apart and most of the reusable parts are taken by hand and seperated by different bins. They are then smashed and put on a conveyor belt where a magnet will take the magnetic parts and the rest go to the smasher and turns into a big bube.
• Pieces of plastic are taken apart, charged with static
electricity, and droped through an electric field, resulting in a natural separation of the plastic types based on pieces being attracted toward the electrode of the opposite polarity. they are then melted at high temperatures and made into new plastic after undergoing a "screening process".

Humans
"We should not wait, we cannot wait, we must not wait."— Al Gore
• Spread word of how humans can help• Clean-up locally• Donate to local clean up crews and/or
recycling and trash companies• Donate to recycling organizations and
programs promoting recycling• Involve all ages
Conclusion
• Citizens have complained about the "hassle" of recycling.
• Recycling is more than worth the "hassle".• "A society is defined not only by what is creates, but
by what is refuses to destroy." -John Sawhill• Please Consider our Proposal• Thank you for listening to our presentation.
