recycling paper

Environmental Industry Associations. (n.d.). What do you need to know about recycling paper?. Retrieved July 15, 2010 from http://www.environmentalistseveryday.org/solid-waste-management/environment-friendly-waste-disposal/recycling-paper.php 

Recycling paper is one of the environmentally friendly methods of waste disposal supported by the solid waste management industry. The Environmental Protection Agency (EPA) says the amount of paper that we generate crested in 2000 and has gone down slightly since then. Paper industry data, which covers all paper consumed in a year and is almost 15 million tons higher than EPA's, also shows a relatively flat supply trend. Both sets of statistics show that per capita paper consumption is declining over time.
What is happening is that we keep finding ways to avoid using paper. E-mail increasingly is replacing paper mail. More and more people are reading newspapers, magazines and books online. All sorts of businesses seek “paperless” ways of doing their business. Plastic bags have pretty much replaced paper bags. More milk is sold in plastic jugs than in paper containers.
Even with these reductions or substitutions, Americans continue to use a lot of paper every day, in our homes, schools and businesses. As a result, paper – including writing paper, corrugated boxes, tissue and toilet paper, newspaper and packaging – remains the largest part of the American waste stream. According to EPA, paper makes up slightly more than a third of our trash. That's more than 86 million tons.
The good news is that more and more Americans are recycling paper every year. Americans recycled more than 50 percent of the paper we used in 2007. But we can achieve even more. Eighty percent of America’s paper mills are designed to use paper collected in recycling programs, and they depend on paper recycling to have the materials they need to operate.

Recycling Paper: Did you know?

  • Recycling one ton of paper typically saves a cubic yard of landfill space.
  • Recycling paper saves energy and reduces pollution. Making new paper from recycled paper uses up to 55 percent less energy than making paper from trees, and reduces related air pollution by 95 percent.

How is paper recycled?

Recycled paper processing mills use paper as their feedstock. The recovered paper is combined with water in a large vessel called a pulper, which acts like a blender to separate fibers in the paper sheets from each other. The resultant paper material then passes through screens and other separation processes to remove contaminants such as ink, clays, dirt, plastic and metals.
Paper fibers from newspaper are recycled back into newspaper, as well as paper game boards, paper egg cartons, paper gift boxes, paper animal bedding, paper insulation and paper packaging material. Paper fibers from office paper are recycled into tissue paper, paper towels and toilet paper. Paper fibers from corrugated cardboard are recycled into corrugated medium, which is a component of a paper box.

Tips for reducing, reusing and recycling paper

Most paper products can be reused or recycled, including newspaper and books, magazines and catalogs, office paper, and certain types of cardboard. Following are some paper recycling tips to get you started.
  • Recycle books by donating them to local libraries, schools, charitable organizations and hospitals. Trade books with friends, or take advantage of web sites like www.PaperBackSwap.com, www.BookMooch.com or www.Freecycle.com to trade your books online. You can also sell your books on eBay or Craigslist, or to a local used bookstore.
  • Take brown paper bags back to the store to recycle them, or check with your municipal curbside recycling program to see if they are accepted at recycling centers. (They usually are.) Reduce your overall use of paper bags by taking cloth tote bags along on your grocery shopping trips.
  • Curbside municipal recycling programs readily accept newspaper. Be sure to remove any rubber bands or plastic bags before you place your paper in the paper recycling bin. Generally, old newsprint should be kept dry and clean.
  • Cardboard is one of the most commonly recycled paper materials. Boxes meant for paper recycling should be emptied and flattened. Wet or greasy cardboard (such as pizza boxes) paper cannot be recycled. Cardboard also works great in composting. Use it to line the compost heap or layer it with wet grass cuttings.
  • All municipal paper recycling programs that accept paper will accept magazines and catalogs, so make sure you are including these paper materials in your sorted recyclables. You can also donate magazines to hospitals or nursing homes. To reduce your catalog waste, register with the Direct Marketing Association’s Mail Preference List. And make sure to cancel any subscriptions for magazines you don’t read.

Pollution & Health

Pulp pollution is a serious problem. Pulp and paper mills pollute our water, air, and soil. The pulp and paper industry is one of the largest and most polluting industries in the world; it is the third most polluting industry in North America.
There are about 500 kraft mills (including about 45 in Canada and 100 in the US), and many thousands of other types of pulp and paper mills, in the world. Primary concerns include the use of chlorine-based bleaches and resultant toxic emissions to air, water, and soil. With global annual growth forecast at 2.5%, the industry, and its negative impacts, could double every 28 years.
People need paper products and we need sustainable, environmentally safe production.
Examples of the Impact of Pulp and Paper Mills on the Environment
The pulp and paper industry is the largest single commercial user of water in Canada. In 1989, the total mill effluent discharged from Canadian bleached pulp mills averaged 137 cubic metres per tonne or 104,000 m3/day (ranging from 25,300 to 311,100 m3/day) which is roughly equal to the flow of the St. Lawrence River at Cornwall, Ontario or to that of the Columbia River in British Columbia. Total mill effluent volumes depend on the grade and amount of pulp being produced.
(* Canadian Environmental Protection Act Priority Substances List Assessment, Report No. 2, Effluents from Pulp Mills Using Bleaching, 1991)
The figure below, from British Columbia, further illustrates the authorized contaminant loading from point sources, including emissions to air, liquid effluents, and solid waste discharges. (Data from the Ministry of Environment, Lands and Park’s waste management fees database, November, 2000.) The 20~23 pulp and paper mills in the province clearly make a significant contribution to the overall pollution loads.
Industrial Polution by source, BC 2000
The impact of all this pollution on the health of the community, the workers and the environment is a subject for much debate and some worry. Studies find it hard to resolve the issues, because there are so many variables, people move, and the environment has a myriad of influences and stresses. Nonetheless there are is a slowly accumulating body of evidence on mill impact on the environment and human beings.


Deforestation



Deforestation:modern-day plague. (n.d.). National Geographic, Retrieved July 15, 2010 from http://environment.nationalgeographic.com/environment/global-warming/deforestation-overview/ 




Deforestation
Modern-Day Plague
Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year.
The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation.
Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families.The biggest driver of deforestation is agriculture. Farmers cut forests to provide more room for planting crops or grazing livestock. Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in a process known as “slash and burn” agriculture.
Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Loggers, some of them acting illegally, also build roads to access more and more remote forests—which leads to further deforestation. Forests are also cut as a result of growing urban sprawl.
Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees.
Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.
Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts.
Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and holds in heat at night. This disruption leads to more extreme temperatures swings that can be harmful to plants and animals.
Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests means larger amounts of greenhouse gases entering the atmosphere—and increased speed and severity of global warming.
The quickest solution to deforestation would be to simply stop cutting down trees. Though deforestation rates have slowed a bit in recent years, financial realities make this unlikely to occur.
A more workable solution is to carefully manage forest resources by eliminating clear-cutting to make sure that forest environments remain intact. The cutting that does occur should be balanced by the planting of enough young trees to replace the older ones felled in any given forest. The number of new tree plantations is growing each year, but their total still equals a tiny fraction of the Earth’s forested land.

Waste and recycling facts







Waste and recycling facts. (n.d.). Clean Air Council, Retrieved July 15, 2010 from http://www.cleanair.org/Waste/wasteFacts.html#_ednref6

WASTE
The average American office worker uses about 500 disposable cups every year.[1]
Every year, Americans throw away enough paper and plastic cups, forks, and spoons to circle the equator 300 times.1
Seattle, Washington, Portland, Oregon, Westchester NY, Berkeley, and Malibu California have all banned Styrofoam foodware. Laguna Beach and Santa Monica have banned all polystyrene (#6) foodware.[2]
During 2009’s International Coastal Cleanup, the Ocean Conservancy found that plastic bags were the second-most common kind of waste found, at 1 out of ten items picked up and tallied.[3]
Over 7 billion pounds of PVC are thrown away in the U.S. each year. Only 18 million pounds of that, about one quarter of 1 percent, is recycled.3
Chlorine production for PVC uses almost as much energy as the annual output of eight medium-sized nuclear power plants each year.[4]
After Ireland created a 15-cent charge per plastic bag in 2002, bag consumption dropped by 90 percent. In 2008, the average person in Ireland used 27 plastic bags, while the average person in Britain used 220. The program has raised millions of euros in revenue.[5]
The state of California spends about 25 million dollars sending plastic bags to landfill each year, and another 8.5 million dollars to remove littered bags from streets.[6]
Every year, Americans use approximately 1 billion shopping bags, creating 300,000 tons of landfill waste.6
Plastic bags do not biodegrade. Light breaks them down into smaller and smaller particles that contaminate the soil and water and are expensive and difficult to remove.6
Less than 1 percent of plastic bags are recycled each year. Recycling one ton of plastic bags costs $4,000. The recycled product can be sold for $32.6
When the small particles from photodegraded plastic bags get into the water, they are ingested by filter feeding marine animals. Biotoxins like PCBs that are in the particles are then passed up the food chain, including up to humans.[7]
The City of San Francisco determined that it costs 17 cents for them to handle each discarded bag. 7
In 2003, 290 million tires were discarded. 130 million of these tires were burned as fuel.[8]
In 2004, the Rubber Manufacturers Association estimated that 275 million tires were in stockpiles. Tires in stockpiles can serve as a breeding ground for mosquitoes and a habitat for rodents. Because they retain heat, these piles easily ignite, creating toxin-emitting, hard-to-extinguish fires that can burn for months.8
The oil from just one oil change is enough to contaminate one million gallons of fresh water. Americans who change their own oil throw away 120 million gallons of reusable oil every year.[9]
More than 2 billion books, 350 million magazines, and 24 billion newspapers are published each year. [10]
The average American uses about the equivalent of one 100-foot-tall Douglas fir tree in paper and wood products each year.10
The average office worker in the US uses 10,000 sheets of copy paper each year. That’s four million tons of copy paper used annually. Office workers in the US generate approximately two pounds of paper and paperboard products every day. 10
Airports and airlines recycle less than 20 percent of the 425,000 tons of passenger-related waste they produce each year.[11]
The estimated 2.6 billion holiday cards sold each year in the U.S. could fill a football field 10 stories high.[12]
Between Thanksgiving and New Year’s, an extra million tons of waste is generated each week.12
38,000 miles of ribbon are thrown away each year, enough to tie a bow around the Earth.12
In 2008, Paper and paperboard made up 31% of municipal waste. Plastics were 12%.[13]
In 2008, only 23.1% of glass disposed of was recycled, and only 7.1% of plastics and 21.1% of aluminum.13
About 31% of MSW generated in the US in 2008 was containers and packaging, or 76,760 thousand tons. Only 43.7% of that was recycled.13
In 2008, the average amount of waste generated by each person in America per day was 4.5 pounds. 1.1 pounds of that was recycled, and .4 pounds, including yard waste, was sent to composting. In total, 24.3% of waste was recycled, 8.9% was composted, and 66.8% was sent to a landfill or incinerated. 13
The average American employee consumes 2.5 cans of soda each day at work.[14]
The beverage industry used 46 percent less packaging in 2006 than in 1990, even with a 24 percent increase in beverage sales in that time.[15]
Landfill:
Although the EPA reports that approximately 33% of municipal waste is recycled, municipal waste makes up only a small portion of all waste generated. These waste statistics also leave out waste that is burned or landfilled in unpermitted landfills and incinerators, like burn barrels.[16]
The barriers of all landfills will eventually break down and leak leachate into ground and surface water. Plastics are not inert, and many landfill liners and plastic pipes allow chemicals and gases to pass through while still intact.16
In 2008, a survey of landfills found that 82 percent of surveyed landfill cells had leaks, while 41 percent had a leak larger than 1 square foot.16
Newer, lined landfills leak in narrow plumes, making leaks only detectable if they reach landfill monitoring wells. Both old and new landfills are usually located near large bodies of water, making detection of leaks and their cleanup difficult.16
Incinerators are a major source of 210 different dioxin compounds, plus mercury, cadmium, nitrous oxide, hydrogen chloride, sulfuric acid, fluorides, and particulate matter small enough to lodge permanently in the lungs. 17
In 2007, the EPA acknowledged that despite recent tightening of emission standards for waste incineration power plants, the waste-to-energy process still “create significant emissions, including trace amounts of hazardous air pollutants.”[17]
Only 30% of people in the Southern region of the United States had curbside recycling collection in 2008. Eighty-four percent of people in the Northeast had curbside recycling. The South also has the most landfill facilities – 726, in contrast with 134 in the northeast.13
Alaska has 300 landfill facilities, while the entire northeastern region of the United States only has 134.13
In 1960, each person in the US only generated 2.68 pounds of waste. In 1970, the figure was 3.25. However, Americans’ recycling has improved since 2000, when the average American generated 4.65 lbs of waste per day, and only 29% was recycled. Also, in 1980, 89% of Americans’ waste went to a landfill, while only 54% met that fate in 2008.[18]
While landfill gas is a good fuel, most landfills are not efficiently collecting it. The EPA estimates 75% gas collection efficiency, but some landfills are as low as 9 percent. The 2006 IPCC report used an estimated recovery efficiency of just 20 percent. Even Waste Management, the largest waste company in the United States, has admitted that it is impossible for them to reliably measure methane emissions at their landfills or develop a general model for estimating them.[19]
Waste incinerators create more CO2 emissions than coal, oil, or natural gas-fueled power plants.17
COMPOSTING
Food scraps were 12.7% of waste generated 2008, while yard trimmings were 13.2%
Only 2.5% of all waste food was composted in 2008 – the rest went to landfill or incinerators.13
30,990 tons of food scraps were discarded in 2008, composing 18.6% of all materials going to landfills or incinerators.13
American per capita food waste increased to more than 1,400 calories per person per day in 2009, an increase of approximately 50 percent since 1974.[20]
Because microbes in compost can degrade some toxic organic compounds, including petroleum, compost is often used to restore oil-contaminated soils.[21]
Compost’s organic matter and microbial content make it similar to wetland soils, and thereby useful for wetland restoration.22
Immature composts, which work against plant growth, are used as natural mulches and mild herbicides.22
In 2009, the EPA concluded that as much as 42 percent of U.S. greenhouse gas emissions could be avoided through strategies like recycling and composting.[22]
Because incinerators are inefficient at generating electricity from burning waste, and recycling and composting conserve three to five times more energy than is produced by incinerating waste, the amount of energy wasted in the U.S. by not recycling is equal to the output of 15 medium-sized power plants.23
Doubling the national recycling rate could create over 1 million new green jobs.23
The United States has more communities working towards Zero Waste goals than all of Europe.23
RECYCLING
It has been estimated that recycling, re-use, and composting create six to ten times as many jobs as waste incineration and landfills.[23]
Recycling saves 3 to 5 times the energy generated by waste-to-energy plants, even without counting the wasted energy in the burned materials.[24]
Making a ton of paper from recycled paper saves up to 17 trees and uses 50 percent less water than does creating paper from virgin pulp.[25]
In 2007, about 360 pounds of paper were recycled for each person in the U.S.9
48.2% of aluminum beer and soft drink cans were recycled in 2008.13
Glass food and drink containers made up 4% of all the waste generated in 2008. Only 28 percent were recycled.13
13.3% of plastic packaging was recycled in 2008.13
In 2008, Americans recycled 7 million tons of metals, eliminating the equivalent of nearly 25 million metric tons of carbon dioxide, or taking 4.5 million cars off the road for one year.19
Nearly 77% of all corrugated boxes were recycled in 2008.19
Recycling 1 ton of mixed paper saves the energy equivalent of 185 gallons of gasoline.19
Recycling 1 ton of aluminum cans conserves more than 207 million Btus, which is equal to 36 barrels of oil, or 1,665 gallons of gasoline.19
The recycling rate of 32.5 percent in 2006 saved the carbon emission equivalent of taking 39.4 million cars off the road, and the energy equivalent of 6.8 million households’ annual energy consumption, or 222.1 million barrels of oil.[26]
The aluminum can industry can make up to 20 cans from recycled aluminum with the same amount of energy it takes to make 1 completely new can.14
Aluminum can be recycled forever with no loss of quality.14
Recycling aluminum creates 97% less water pollution than making new metal from ore.14
Every 3 seconds a baby is born. In that time, 140 cans are born.14
Every ton of glass containers recycled saves over a ton of natural resources.[27]
For every 10% recycled glass used to make new glass containers, energy costs drop 2-3 percent.28
The energy saved by recycling one glass bottle can light a 100-watt light bulb for four hours or run a computer for 30 minutes.28
Since 1960, the rate of office paper recycling has more than quadrupled.[28]
63.4 percent of paper was recycled in 2009, an all-time high, according to the American Forest & Paper Association. 2009 was the first year the rate was over 60 percent.[29]
If we recycled all of our aluminum cans for one year, we could save enough energy to light Washington, D.C. for 3.7 years.[30]
A recycled aluminum can can be back on the shelf in 60 days.31
The amount of aluminum currently recycled in 1 year is enough to rebuild our entire airplane commercial fleet every 6 months.31
Producing one pound of recycled rubber requires only 29 percent as much energy as producing one pound of new rubber.31
The 1.14 million tons of paper products recycled in Pennsylvania in 2004 resulted in forest carbon sequestration benefits equal to nearly 82 million tree seedlings grown for ten years.[31]
BOTTLED WATER
At least 90 percent of the price of a bottle of water is for things other than the water itself, like bottling, packaging, shipping and marketing.[32]
44 percent of ‘purified’ bottled water sold in the U.S. started out as municipal water.[33]
827,000 to 1.3 million tons of plastic PET water bottles were produced in the U.S. in 2006, requiring the energy equivalent of 50 million barrels of oil. 76.5 percent of these bottles ended up in landfills.34
Between 1997 and 2007, bottled water consumption in the U.S. more than doubled, from 13.4 gallons per person to 29.3 gallons per person.[34]
26 to 41 percent of the 2.4 million tons of PET plastic discarded every year is bottled water bottles.35
Because plastic water bottles are shielded from sunlight in landfills, they will not decompose for thousands of years.35
It takes about 1,100 to 2,000 times as much energy to produce and transport the average bottle of water to Los Angeles as to produce the same amount of tap water.35
ELECTRONICS
Only 10 percent of the 140.3 million cell phones retired in 2007 were recycled.[35]
Of the 2.25 million tons of electronics (TVs, cell phones, computers, etc) retired in 2007, 82 percent were discarded, mostly to landfills.36
About 40 million computers became obsolete in 2007, about twice as many as in 1998.36
About 304 million electronics were disposed of from US households in 2005. Two-thirds of them still worked.36
If we recycled all of the cell phones retired each year, we would save enough energy to power 18,500 homes for a year.[36]
In 2007, 82 percent of retired televisions and computers were discarded, mostly to landfills.[37]
In 2005, 61 percent of CRT monitors and televisions collected for recycling were sent abroad for remanufacture or refurbishment, mostly to Asia or South America. Another 14 percent was sent abroad for glass-to-glass processing.38
Recycling one million laptops saves enough energy to power 3,657 American homes in a year.38
Recycling one million cell phones allows 35,274 pounds of copper, 772 pounds of silver, 75 pounds of gold, and 33 pounds of palladium to be recovered.38
