The self-report composition of garbage is about 450 words.

Did you ever think that we would be useful one day when you threw us bag by bag from your house into the trash can? Now our family is paid more and more attention by human beings, and people use high-tech means to turn waste into treasure. Can we not be excited and proud? There are many family members in our family: sister of waste glass, brother of waste plastic, brother of waste paper, sister of waste metal and other brothers and sisters. If we classify and recycle family members and then deal with them scientifically, it will be of great use. Let's talk about waste glass first. She used to be very naughty, doing bad things everywhere, and some people even got tetanus after being stabbed. But now, after human recycling her, recycling glass can not only save quartz sand, soda ash, feldspar powder, coal and other materials, but also save electricity, reduce energy consumption by 32%, reduce air pollution by 20% and water pollution by 50%. Are you surprised that so much energy has been saved? To tell you the truth, the energy saved by recycling a glass bottle can make the light bulb shine for 4 hours! Let's talk about waste plastic. In the past, man used plastic products and threw them into the ground like garbage, but he slept underground for 100 years and didn't rot, and it floated everywhere with the wind. At this rate, the world is full of white pollution. How do humans survive? So the little brother of waste plastic was covered with "white sanitary balls" everywhere, which made him unable to lift his head. Now, scientists have carried out the secondary development of waste plastic brothers, turning harm into benefit, and developed a new type of thermal insulation insulating brick with low cost, good fire prevention performance and good thermal insulation effect, which is suitable for use in different climatic conditions. Now, Brother Waste Plastic can not only look up in front of "people", but also become a "waste" star. The role of waste paper elder brother and scrap iron elder sister is greater. Recycling one ton of waste paper can produce 800 kilograms of high-quality paper. Do you know that?/You know what? The raw material for producing paper is trees. If 800 kilograms of paper is produced from waste paper, 17 trees can be cut down less and water pollution can be reduced by 35%. Can brother waste paper be recycled? In fact, every waste paper brother can recycle it at least twice. As for the metal sister, it is even more necessary to collect it. Mineral resources are non-renewable resources. It takes thousands of years for her to form under special circumstances, and she can reuse them many times. For example, using aluminum cans and aluminum waste packaging to smelt aluminum consumes 765,438+0% less energy, reduces 95% air pollution and has high purity than using bauxite to extract aluminum. Me, of course, it's kitchen waste, such as Gu, which piles me up for fermentation and turns me into fertilizer B with toxic side effects, but it's better than ordinary emperors seeing me cover up and fertilize. You see, the people in O are munching = the longer the better, and the stick in X is afraid of being robbed = the greener the stick, the more knots there are. The ditch where the instrument is covered with fertilizer is not only caused by the lack of Z alkali, but also the residual fertilizer is harmful to human health. Everyone doesn't like to eat V, but farmers like our pure natural and pollution-free fertilizer? How about r? My family members also have their own uses. In fact, we still have many places that are beneficial to mankind. I hope you will not abandon us, use your brains and try to make more contributions to mankind!
