RECORDs are broken!
Earth needs an environmental balance!
In the US the word TAR is often used when discussing the mining of
'tar sands'. The more correct word would be asphalt or bitumen sand.
What are 'tar sands'?
Tar sands contain ~90 % sand or sandstone, water, and clay mixed with only about 10 % high-sulfur bitumen, a viscous black petroleum sludge rich in hydrocarbons, also known as natural asphalt.
Removal of tar-sands
Geologically tar is closely related to oil. About 130 million years ago, ancient sea life and algae were sinking on the ocean floor after they died. More and more layers were packed on each other, often covered by sand and mud. As the pressure went up, the temperatures were rising too, transforming these dead sea life forms into asphalt, bitumen, kerogen, petroleum, oil.|
It took millions of years to transform these dead carbon rich bodies into 'tar' = bitumen.
||If we would burn these hydro carbon in the same time period,(millions of years) no harm would be done, but in the last 12 months more Carbon Dioxide CO2 was produced and released into Earth's atmosphere by mankind than ever before: up to 120 million pounds a minute ...|
Tar / bitumen is primarily Carbon = chemically C|
Sulfur, hydrogen, oxygen, nitrogen and many other chemicals, toxic and non-toxic
Tar / Bitumen is a fossil fuel,†what means that Earth needed millions of years to produce it.
Huge amounts of sea life were pressed over millions of years
In the past the largest use of asphalt/bitumen was for making asphalt concrete for road surfaces. 5% asphalt/bitumen cement and 95% stone, sand, and gravel
is used for Asphalt concrete pavement. Because bitumen is so thick, it needs to be heated, to become liquid enough to be mixed. About 7,600 asphalt concrete mixing plants are producing road material in Europe and the United States.|
In the US asphalt roofing shingles are widely used, some cattle sprays, fence-post treatments, and waterproofing for fabrics needs tar = bitumen.
|In Canada is a burial site of ~ 170 billion barrels of tar-sands. Up to 2500 ft deep, huge machinery is digging in forests areas, removing all life forms: many bears, lynxes, trees, and anything else that creeps, crawls, and grows, to get to the tar-sands|
Today we have the technologies to use fossil fuels in very different ways.|
Why are we still burning oil and coal, when we know that it is the most inefficient, most resource wasting method?
The problem for all life on Earth is that humans are burning fossil fuels in a very short time!
The plants removed CO2 = carbon dioxide for hundred-thousands of years, now humans release the trapped CO2 in a very short time
Do you think humans change our atmosphere when burning these amounts of bitumen sand?|
Humans burn fossil fuels for energy!
Humans get health problems from air pollution!
Children get learning disorders from burning fossil fuels!
Ten thousands of people die every year,
because some companies look only for profit
without taking any responsibility!
To get oil out of these tar sands, one needs to extract the bitumen from the sands.|
A) The material will be crushed with enormous machines.
B) To make a slurry, the crushed sands need to be mixed with hot water
†††(Think about the energy needed to crush and heat the water ...)
C) The bitumen in the slurry can now be scooped off.
D) The material needs to be more liquid, so it can run through a pipeline.
†††So one needs to add solvents (not all of them are natural...
E) To process the sludge at the end of the pipeline, the solvents need to be removed again.
F) The process is called hydro-treating. That sounds good, but what happens to the ingredients as nitrogen, sulfur, metals? Nothings works without energy, so again a lot of water and energy is needed.
G) After that process the remaining material needs to be heated up again.
H) Refinement of the bitumen is the last step before it can be sent to an oil refinery.
Hurrah, we have made gasoline out of tar sands!!
If you would add the costs of the destruction of Nature, the damage to the water, the changed and poisoned atmosphere, one gallon of this new gasoline would cost about US$6.30
But no company pays for environmental damage, and as far as we know, no government is charging for it. Let the people pay for it, they are used to it!
Four tons of sand + four barrels of fresh water were use to produce one barrel of synthetic oil. Companies have started to recycle water, about 10 percent is a good number, isn't it?
What about the rest?
About 90% are dumped in huge tailing ponds, as you can see them on the photo above. The one you see lies along the Athabasca river, and nobody thinks it is possible that this poisonous garbage water will run into this river, or that there would be a possibility that it seeps into the ground.
Say Good bye to healthy drinking water for the whole area!
In case you think gasoline is more important than drinking water:
The Alberta operation uses more water than a city of a million people each year.
Read our information - get the facts!
Tar / bitumen burning releases some chemicals in the air:|
B) Sulfur dioxide
C) Nitrogen oxide
D) volatile organic compounds
A report from the National Research Council shows, that air pollution-related health impacts alone represent about $67 billion a year in hidden costs payed by all of us.
Think about the costs of fossil-fuel-related water pollution,
the cost of cleaning up after a tailing pond floods,
the cost of pipeline as long as intact and if it leaks,
the loss of some of Canada's oldest, most bio-diverse forests.
