Reduce,
Reuse, Recycle, Recover
Garbage gone but not forgotten!
Most of our garbage is sent to landfills,
dumps or municipal incinerators. But with
more and more people producing more and
more waste, landfills are filling up faster
than we can find new sites for them. And
landfills create new types of waste. As
garbage decomposes, moisture filters through
it producing a toxic liquid known as leachate.
Modern landfills are designed to reduce
the amount of moisture that reaches the
garbage, and many have a system to collect
and treat the leachate.
Decomposing garbage also produces two greenhouses
gases: carbon dioxide and methane, and invisible,
odourless, and highly flammable gas. At
some big landfill sites, methane is now
being collected and burned to produce energy.
Water and oxygen are required to break down
garbage. But water and oxygen in short supply
deep in a landfill, so decomposition takes
place very slowly. In fact, when researchers
cored down into a landfill in the United
States, they discovered newspapers over
30 years old still in readable condition!
Incinerations are sometimes used to burn
solid waste under controlled condition.
They reduce the stress on landfills, but
they create other environmental problems.
The ashes must be disposed of, either at
a landfill, or, if they are toxic, at a
hazardous waste facility. Burning garbage
also produces acid gases, carbon dioxide
and toxic chemicals that must be treated
with expensive air pollution control equipment
to avoid contributing to acid rain, ozone
depletion and air pollution.
Recycling is just one way to reduce wastes.
To be really effective, we have to incorporate
the 4Rs- Reduce, Reuse, Recycle and Recover
into our daily routine.
Reducing the amount of waste we produce
is by far the most effective way to battle
the flow of garbage into the landfill. Packaging
makes up about half our garbage by volume,
one-third by weight.
When you shop, try to find products that
have little or no packaging.
What we cannot Reduce we should try to Reuse.
Repair you old radio rather than buying
a new one.
Use jars, tins, and plastic containers to
store leftovers, bulk foods and household
items.
Buy durable, good quality products that
will last.
Materials and packaging that cannot be reused
should be recycled at home, work and school.
You can contribute to recycling by purchasing
recycled and recyclable products.
At the store, ask yourself these questions:
Can this product or its packaging be reused
or recycled? Was it produced form recycled
materials? Whenever possible, choose products
that meet these criteria.
Finally, Recover energy from wastes that
cannot be used for something else. This
fourth R is difficult to put into practice
by individuals, and is geared more toward
industry.
SOME TIME IN THE DISTANT FUTURE, AN ARCHAEOLOGIST
LOOKING BACK AT LATE 20TH CENTURY WILL MARVEL
AT WHAT A WASTEFUL SOCIETY WE WERE. THINK
BACK THROUGH YOUR DAY: THE EMPTY TOOTHPASTE
TUBE, THE CEREAL BOX, THE POP CAN IN YOU
LUNCH, YOUR GUM WRAPPER, THE FOOD YOU LEFT
ON YOUR PLATE AT DINNER. NATURAL RESOURCES
SUCH AS WATER, WOOD AND FOSSIL FUELS GO
INTO THE PRODUCTION AND TRANSPORTATION OF
ALL THESE THINGS. WHEN WE THROW THEM AWAY,
WE ARE THROWING AWAY OUR VALUABLE RESOURCES.
NO WONDER THE ARCHAEOLOGIST OF THE FUTURE
FINDS US WASTEFUL!
Did you know?
About 1/3 of our waste is paper and paperboard.
Another third is yard and kitchen waste.
The rest is divided among glass, metals,
plastics, textiles, wood and other materials.
Reduce, reduce reduce!
There are many things you can do to reduce
the amount of waste you produce.
-
Avoid food packaged in individual servings.
-
Buy in bulk. It saves money and the
environment.
-
Buy
multi-use items rather than single-use
when possible.
-
Use
your own cloths bags for shopping.
-
Donate
your old clothes to charity.
-
Buy
beverages in refillable containers.
-
Use
rechargeable batteries.
-
Share
your newspaper, magazines and books
with a friend.
-
Wrap
presents in reusable cloth bags or reused
wrapping paper.
-
Rent
items you use infrequently.
-
Pack
your lunch in reusable containers.
-
Support
your community's recycling programs.
-
Buy
products that contain recycled materials.
-
Use
both sides of every sheet of paper.
-
Use
a durable refillable mug or glass at
school or work.
-
Encourage
your friends and family to follow your
good example.
Fact:
If we all work at reducing our own wastes,
together we will make a BIG difference.
Be creative. There are many more ways we
can reduce the wastes we produce.
