쓰레기 매립장 가스, 친환경 에너지로 변신
Gases from landfill sites are a major source of air pollution.
Korean researchers have developed a technology for converting such greenhouse gases into green *energy.
Park Se-young has more.
Landfills produce methane and carbon dioxide, which are both greenhouse gases.
Some large landfills build electricity production facilities and utilize these waste gases, …but around 75 percent of landfills nationwide are small or medium-sized.
Now, Korean researchers have developed a way to convert the emissions from these landfills into synthetic gas, then into methanol and green gas using plasma technology.

“By using thermal energy derived from plasma for catalysts, we’re studying whether we can reduce the costs of the process.”

The researchers have secured the technology for controlling plasma and boosted thermal efficiency by about 30 percent to 76 percent.
By doing so, they were able to convert up to 99 percent of methane and carbon dioxide into green gas.
Using a vortex to spin the plasma also maximizes the efficiency of the process and cuts costs to one-tenth what they were previously.
The researchers plan to raise the technology’s business value through the operation of demonstration plants and are looking to enter overseas markets.
The study was published in the journal Plasma Processes and Polymers.

New York City’s greenhouse gas emissions as one-ton spheres of carbon dioxide gas



Views:366175|Rating:4.87|View Time:3:13Minutes|Likes:1266|Dislikes:34
In 2010 New York City added 54 million metric tons of carbon dioxide (equivalent) to the atmosphere, but that number means little to most people because few of us have a sense of scale for atmospheric pollution.

Carbon Visuals ( and Environmental Defense Fund ( wanted to make those emissions feel a bit more real – the total emissions and the rate of emission. Designed to engage the ‘person on the street’, this version is exploratory and still work in progress. Mayor Bloomberg’s office has not been involved in the creation or dissemination of this video.

NYC carbon footprint:

54,349,650 tons a year = 148,903 tons a day = 6,204 tons an hour = 1.72 tons a second

At standard pressure and 59 °F a metric ton of carbon dioxide gas would fill a sphere 33 feet across (density of CO₂ = 1.87 kg/m³: If this is how New York’s emissions actually emerged we would see one of these spheres emerge every 0.58 seconds.

Emissions in 2010 were 12% less than 2005 emissions. The City of New York is on track to reduce emissions by 30% by 2017 – an ambitious target.

Do you know what is carbon footprint and how to reduce it?

Your Carbon Footprint is the amount of Carbon Dioxide and Methane gas you release into the environment by consuming energy.

Most energy produced in the world is done by burning fossil fuels such as petroleum and gas. You may not experience it directly but everything you do requires energy. You need petrol to create energy to drive your car, gas to light your stove, and even the paper you write on in school requires energy to be transformed from wood to books.

There is no clean way to burn fossil fuels. No matter how you do it, you will produce carbon dioxide (CO2) emissions in the process. Hence, Your carbon footprint is the total amount of carbon dioxide and methane gas you release into the environment by consuming energy.

To get a better idea of how consuming something adds to your carbon footprint take the example of paper. Let’s say that plants take 5 units of energy to become trees. It takes 1 unit to cut down the tree and 3 units to transport it to a factory. The factory takes another 5 units to convert this tree into paper. Finally another 1 unit is used to transport that paper to your city. This means that when you buy the book it is worth 15 units of energy.

It may take you less than 1 unit of energy to throw a book into the dustbin but in reality you are chucking away 15 units of energy. Now think of every person in the whole world throwing away just 1 book and you get 7 billion X 15 units of energy when someone simply throws away a book

Watch this video to understand how our everyday activities add to our Carbon Footprint and how we can conserve energy.

Imagine that aliens landed and gifted us a clean, limitless energy source. And instead of killing each other over this technology, we decided to immediately transform the world into a carbon-free society. This wonderous source would power our homes, industries, cars and planes, and humanity’s annual rate of carbon pollution would almost instantly fall to zero. So if we kicked our carbon addiction tomorrow, what would that mean for global warming?
