Waste to Energy—JUST BURN IT!

WHY BURN WASTE?

Waste-to-energy plants generate (产生) enough electricity to supply 2.4 million households in the US. But, providing electricity is not the major advantage of waste-to-energy plants. In fact, it costs more to generate electricity at a waste-to-energy plant than it does at a coal, nuclear, or hydropower plant.

The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. The average American produces more than 1,600 pounds of waste a year. If all this waste were landfilled, it would take more than two cubic yards of landfill space. That’s the volume of a box three feet long, three feet wide, and six feet high. If that waste were burned, the ashes would fit into a box three feet long, three feet wide, but only nine inches high!

Some communities in the Northeast may be running out of land for new landfills. And, since most people don’t want landfills in their backyards, it has become more difficult to obtain permits to build new landfills. Taking the country as a whole, the United States has plenty of open space, of course, but it is expensive to transport garbage a long distance to put it into a landfill.

TO BURN OR NOT TO BURN?

Some people are concerned that burning garbage may harm the environment. Like coal plants, waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity. Burning garbage releases the chemicals and substances found in the waste. Some chemicals can be a threat to people, the environment, or both, if they are not properly controlled.

Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍，阻碍) recycling programs. If everyone sends their trash to a waste-to-energy plant, they say, there will be little motive to recycle. Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place. Massachusetts, New Jersey, and New York City have delayed new waste-to-energy plants, hoping to increase the level of recycling first.

So, what’s the real story? Can recycling and burning waste coexist? At first glance, recycling and waste-to-energy seem to be at odds (不一致), but they can actually complement (弥补) each other. That’s because it makes good sense to recycle some materials, and better sense to burn others.

Let’s look at aluminum, for example. Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself. Burning it produces no energy. So clearly, aluminum is valuable to recycle and not useful to burn.

Paper, on the other hand, can either be burned or recycled—it all depends on the price the used paper will bring.

Plastics are another matter. Because plastics are made from petroleum and natural gas, they are excellent sources of energy for waste-to-energy plants. This is especially true since plastics are not as easy to recycle as steel, aluminum, or paper. Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials.

To burn or not to burn is not really the question. We should use both recycling and waste-to-energy as alternatives to landfilling.

Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更换）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.

The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."

Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.

At present , the U.S. has no federal law for the disposal (处理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (过滤) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."

What does the underlined word "retrieve" (paragraph 2) probably mean?

A. look into B. take apart C. get back D. throw away

What of the following statements is true according to the passage？

A. The U.S. has strict national laws for dealing with e-waste.

B. Third world countries import e-waste to get valuable parts, which is a safe and easy way to make money.

C. The way uneducated workers deal with old computers does great harm to the environment as well as to their own health.

D. More and more electronic waste is being wasted and thrown away mainly because of people's bad habits.

What is the purpose of writing the passage?

A. To attract more people's attention to e-waste.

B. To call on people not to throw away e-waste anywhere.

C. To tell people what e-waste is and how to deal with it well.

D. To warn people to break away from the electronic industry.

The next paragraph probably concerns ___.

A. how to deal with e-waste properly

B. how to protect ourselves from harm by e-waste

C. How to slow down the development in the electronic industry

D. how to make full use of e-waste

Reduce, reuse, and recycle. This familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways. The concept is being used to deal with one possibly dangerous form of waste — electronic junk (电子垃圾), such as old computers, cell phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.
“A lot of these materials are being sent to developing nations under the excuse of reuse — to bridge the digital divide,” said Richard Gutierrez, a policy researcher.
One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.
Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”
China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial is finally beginning to take the lead.

It was your birthday, and you just opened your biggest gift — a smooth silver laptop. You can’t wait to instant-message your friends with the news, but first you have to get rid of your old desktop computer. Do you just throw away the monitor and keyboard in the trash? Not anymore!
Three states, that is, California, Maine, and Maryland, recently passed laws prohibiting people from throwing away electronic waste, or e-waste, includes televisions, computers, and cell phones. Although they don’t make you sick when you use them, they do when they are destroyed, for they contain heavy metals that can be harmful to human bodies. For example, cell phone batteries contain a kind of chemical causing damage to kidneys and deserted computer monitors can damage brains. And flat TV screens may cause injury to the nervous system. Those metals can leak into the ground or give off pollutants when burned.
It is required that e-waste be placed at special sites rather than usual landfills. Several other states are considering similar laws and California is also pushing for a law banning the application of such dangerous substances.
Government officials are not the only people taking aim at e-waste; environmentalists are also urging people to recycle their outdated equipment.
“It is just a waste … to not recycle,” Patrick, an associate professor of occupational and environmental health at university of Iowa, told The Daily Iowan, “Allowing dangerous chemicals to leak into the environment for decades seems irresponsible.”
What Can You Do?
Reduce. Be a responsible shopper, and take care of your electronics so they will last longer.
Re-use. Donate or sell your old high-tech equipment.
Recycle. To find a responsible recycler, contact a local or state environmental group.
