We have been used to wearing masks(口罩)in...

    We have been used to wearing masks(口罩)in public since February. About 300 million masks are used and then thrown away every day in China. Where do these masks go? You might think they just go in a rubbish bin. But that's just the first stop on the masks' journey.

After the masks are thrown into the bins, rubbish trucks empty the bins and take the rubbish to landfills(垃圾场). Next, the masks will be taken to rubbish incinerators(焚化炉)and burned. Burning masks might not seem to be very good for the environment. Won't it cause pollution?

The answer is "no", according to China Daily. The main material of most masks is polypropylene(聚丙烯). It's non-toxic(无毒的). After burning, it changes into water and CO2.

In fact, burning the masks can bring some benefits(益处). The process of burning the rubbish can produce electricity. Burning one ton of rubbish can produce more than 400 kilowatt hours()of electricity. Some people make a prediction that there will be 162,000 tons of used masks in China this year. Burning all of them can produce more than 64 million kilowatt hours of electricity. This is enough to make an electric car drive about 370 million km, which is 9,250 times as long as the earth's equator.

At last, the slag(残渣)from burning masks can be recycled to make bricks(砖块)or fill the roads.
