Everyone
produces waste – an estimated 600 times of our body weight in a lifetime,
that’s an awful lot!
Throwing things
away is a bad habit; recycling them is desirable. Most things that you throw
away can be recycled and turned into new products—although some are easier to
recycle than others. When you throw stuff away, you might be very glad to get
rid of it! Unfortunately, that’s not the end of the story. The things we throw
away have to go somewhere—usually they go off underground in a landfill or
burnt in an incinerator, either ways its bad – landfills leach harmful
chemicals which pollutes soil, water and air; incinerators produce smoke/gas
that pollute the environment and sometimes punch a hole in the Ozone layer
above us, half the way to space.
What we really
need to do is think harder about how we produce waste and how we dispose of it.
It will always be better not to produce waste in the first place than to
recycle it, so reducing the need for things is always the best option.
Less is more!!
4Rs – Refuse,
Reduce, Recycle, Reuse.
- Refuse
– Think before buying, do the need-vs-want analysis.
- Reduce
– Consume in right quantities, be it food, clothes, electronics, appliances.
- Recycle
–
- Reuse
– Before disposing, try to use until it wears out
Think carefully about what you use,
where it comes from, and where it goes. Try to reduce, reuse, and recycle if
you possibly can—and in that order! Be a thoughtful consumer, not a reckless
one, and you’ll be doing your bit to save the environment.
Maybe you have real doubts about the
positive impact of recycling. Maybe you think it is only “hippy”
stuff. Maybe you have a school report due, if so sorry about the previous
allegations.
This page aims to show you the many
ways recycling helps us and the environment.
Turns out there are many reasons to
recycle other than the good feeling you may get from doing it. Recycling saves
landfill space, conserves resource, saves energy and saves water. Recycling is
only the tip of the environmental ice burg; reducing your waste and reusing
what you have will always be better. However, you may be surprised how much of
an impact recycling really has.
Here is a quick run down on the
impacts on the environment based on the materials. These numbers were taken from
a 2005 US Senate report:
Paper:
Newsprint
One ton of recycled newsprint saves
601 Kwh of energy, 1.7 barrels of oil (71 gallons),10.2 million Btu’s of
energy, 60 pounds of air pollutants from being released, 7,000 gallons of
water, and 4.6 cubic yards of landfill space.
Office Paper
Recycling one ton of office paper
saves 17 trees, 7,000 gallons of water, 463 gallons of oil, 3 cubic yards of
landfill space, and enough energy to heat an average home for six months
trees. Further, manufacturing one ton of
office paper using recycled paper stock can save 3,000 to 4,000 kilowatt hours
versus making that amount using virgin materials.
Plastic:
One ton of recycled plastic saves
5,774 Kwh of energy, 16.3 barrels of oil, 98 million Btu’s of energy, and 30
cubic yards of landfill space.
Glass:
One ton of recycled glass saves 42
Kwh of energy, 0.12 barrels of oil (5 gallons), 714,000 Btu’s of energy, 7.5
pounds of air pollutants from being released, and 2 cubic yards of landfill
space. Over 30% of the raw material used in glass production now comes from
recycled glass.
Metal:
Aluminum
Recycling of aluminum cans saves 95%
of the energy required to make the same amount of aluminum from its virgin
source. One ton of recycled aluminum saves 14,000 kilowatt hours (Kwh) of
energy, 40 barrels of oil, 238 million Btu’s of energy, and 10 cubic yards of
landfill space.
Steel
One ton of recycled steel saves 642
Kwh of energy, 1.8 barrels of oil, 10.9 million Btu’s of energy, and 4 cubic
yards of landfill space.
How does Recycling Save Landfill
Space?
This is the easiest to understand.
Everything you throw in the trash will end up buried in a landfill. In Santa
Barbara County, while different recyclables are separated from each other,
trash is not separated into different recyclable materials. Some Examples:
How does Recycling Save Resources?
Paper and cardboard come from trees,
plastics from oil, metals from rocks called ores and glass from sand. Recycling
means that we don’t have to chop down, extract or mine to collect more raw
materials for making the things we use every day.
The US EPA and other sources give us
these estimates for resource savings for one ton of these materials.
One ton of paper recycle saves 17
trees [EPA].
One ton of plastic saves 16.3
barrels of oil [Stanford].
One ton of aluminum saves 4 tons of
Bauxite Ore [MadeHow.com].
One ton of glass saves one ton of
mixed limestone, soda ash and sand [EPA, Stanford].
How does Recycling Save Energy?
This is most clear from the resource
question above. Take a look at Aluminum. It takes 4 tons of Bauxite ore to make
one ton of aluminum. That bauxite has to be mined, transported, crushed, mixed
with caustic soda, heated and separated from impurities. After that the
separated material is smelted, which basically means being heated to extremely
high temperatures, to separate the aluminum. Recycling an aluminum can requires
that the can be transported, separated from commingled recyclables, and melted.
Not only does the melting take a lot less energy, you aren’t dealing with all
the other processes you needed to do to separate the aluminum from bauxite!
Take a look at MadeHow.com for more information about aluminum production.
This general rule applies to most
materials: manufacturing them out of raw resources takes more energy than using
a recycled product.
One way to look at this is to see
how far an object could be transported before the energy recouped from
recycling is lost. This information was taken from an article published in
Resource Recycling in 2009. Researchers used the EPA WARM model to calculate
how far you can ship goods by truck, rail and freighter ship before you don’t
have any energy savings from recycling them. Lets look at a few materials
shipped by truck, the least effiecient method of transportation.
Glass – 2,000 miles by truck
Plastic #1 (PET) – 10,000 miles
Newspaper – 21,000 miles
Aluminum – 103,000 miles
Circumference of the Earth – about
24,900 miles.
What does it mean? You can send
aluminum around the world 4 times on a big rig truck and you will still save
energy by recycling it. You can’t actually do that, since your average big rig
can’t drive on water, but if you switch to train or frieghter ship, the
effieciency gets even better.
