Recycling is Worth the Effort - The Facts
- Do we actually know that recycling is good for the environment?
- Do we have scientific evidence that supports our well-meaning actions saving
energy to preserve natural resources and curb greenhouse gases?
- Are we just guessing that 'reducing waste' equates to 'saving the planet'?
- And is it worth the additional cost?
Recycling is an important part of daily life in most countries around the world.
Research shows each week 1% families and businesses are changing to sensible
recycling habits.
A further five per cent have access to local drop-off recycling centres.
At the last count, the average household was diverting a quarter of weekly
garbage into recycling crates making that effort in the belief
Recycling is good for the environment' and will help shape a better Planet for
future generations.
Government agencies and councils insist on waste minimisation, They have become
a keen advocate of recycling in the context of economic and Environmental
sustainability. After all is said and done, Governments are the people's
representatives, inside a decade we are finally listening to our scientists.
The Scientific Studies
People can be reassured that recycling is an appropriate environmental solution,
thanks to two recently completed Australian scientific studies:
The first, Life Cycle Assessment for Paper and Packaging Waste Management In
Victoria, is a Melbourne-based research project carried out by a group of
universities to fully investigate the environmental benefit (and detriment) of
recycling versus waste to landfill. This study was primarily sponsored by
EcoRecycle Victoria.
The second is an Australia-wide study, commissioned by the National Packaging
Covenant Council (NPCC), entitled Independent Assessment of Kerbside Recycling
in Australia. The most comprehensive study of recycling undertaken in Australia,
this report measures the financial, environmental and social impacts of
recycling, translating the environmental impacts into dollars to compare costs
and benefits.
Each of the above studies used the latest internationally respected
methodological insights to analyse and compare the impacts of recycling to
simply dumping waste into landfill.
Now we know that recycling is environmentally sound, just how is it?
Creating such great benefits?
CUTTING GREENHOUSE GASES:
According to the LCA report, almost half of the greenhouse savings made by
recyclers were found to be from avoiding the production of methane gas, this
would have been generated at landfill as paper waste breaks down. (That figure
even assumes that 55% of that methane would be captured for power generation).
The rest of the greenhouse savings were due to the avoidance of 'virgin material
production'. In other words, if a product was made from raw material rather than
recycled material, more CO2 and other greenhouse gases would have been
generated.
SAVING ENERGY:
Most recycled products showed savings in embodied energy - that is, energy used
in every part of the production of the product, from mining or harvesting of
virgin (raw) materials, through to processing and disposal or recycling.
Embodied Energy Savings per kilogram in the production of recycled product as
compared to an equivalent virgin product:
- Product Embodied Energy Savings
- Newsprint 34%
- Corrugated board-unbleached 22%
- Steel Slab 79%
- Aluminum Ingot 93%
- HDPE 79%
- PET 76%
- PVC 80%
- Glass 57%
REDUCING SMOG:
For recycled plastics (PET and HDPE) steel and (to a lesser extent) newsprint
and paperboard, potential smog pollution from production of virgin materials and
use of landfill is larger than from collection and recycling processes.
PRESERVING WATER:
The savings in water use resulted from reduced water consumption when using
recycled materials for production, compared to the amount of water used in
production from virgin materials.
Let's Explore Some Urban Myths
Now we have the scientific data, let's address some common misconceptions about
recycling and its effects on the environment and community.
THE 'ENERGY' MYTH
"The amount of fuel wasted to power the trucks that pick up recycling crates
undo any good recycling does. We're just using up fuel and pumping more exhaust
fumes into the atmosphere...."
FALSE: In the LCA report, all of the environmental savings found to be made by
recycling were made taking into consideration 'embodied energy', which is energy
consumed in every part of a product's life cycle, including production and
transportation.
In other words, the study's results take into consideration any negative effect
of truck fuel usage.
THE 'LANDFILL CRISIS' MYTH
"We only started recycling because places like New York ran out of land on which
to bury their litter. Australia's a big country.
We don't have that problem... There is no landfill crisis!
Recycling is a waste of time."
FALSE: Recycling is about more than finding space in which to dump our unwanted
materials! It is about saving natural resources, conserving energy, curbing the
greenhouse effect, and reducing water usage. The LCA report finds that, compared
to dumping in landfill, recycling makes significant environmental savings in all
of these areas!
We also know that nobody wants a landfill 'in his or her back yard'.
This is just another reason why it makes sense to support recycling as a waste
minimisation solution.
THE 'RUBBISH IS BIODEGRADABLE' MYTH
"Litter degrades anyway. If we throw away our rubbish it gets put into the
ground, so we're giving back what we take out."
FALSE: Firstly, your waste bin isn't full of 'rubbish", it's full of valuable
untapped resources. Secondly, not all rubbish degrades. Even with organic matter
(such as paper), which is the most efficient of materials to degrade, there are
arguments about the speed with which it actually breaks down. Modern landfills
are designed specifically to prevent leaching of residues; unfortunately the
same technology that stops leaching also blocks air and water from entering the
landfill and thus the breakdown of materials is hindered.
When organic materials do break down at landfill they create CO2 and methane.
It's currently assumed that, on average, 55% of that gas is captured for power
generation. Half of the remaining amount is lost to the atmosphere to become a
potent greenhouse gas.
THE 'RECYCLING ISN'T WORTH IT' MYTH
"Recycling isn't worth it. It's all very well saving resources, but in practical
terms we have economies to run. Communities are wasting money on kerb side
recycling."
FALSE: As the NPCC study shows, recycling has a net environmental benefit to the
community. The report concludes that, taking into consideration the financial
costs of recycling and the environmental 'dollar' costs, the overall national
benefit is an estimated $266 million per year!
Keep on Recycling...and Reducing and Reusing!
The best way to preserve natural resources, reduce air pollution, save energy
and cut greenhouse gasses is to avoid creating waste in the first place.
- REDUCE THE AMOUNT OF WASTE GENERATED
- REUSE PRODUCTS WHEREVER POSSIBLE
- RECYCLE UNWANTED MATERIALS.
If we keep up the good work, future generations deserve a better deal.
Always remember: "Together we can make a difference"
