How to deal with domestic garbage? Tell me what you think.

All kinds of solid and semi-solid wastes produced in production, consumption, life and other activities are called garbage.

The garbage problem has now become a big problem in the world. Do you know how much rubbish is around us?

First of all, discarded CDs

The appearance of computers has brought us a lot of convenience and fun, but at the same time, at home, we will find a pile of old CDs piled up in a corner. Most of these CDs are discarded because of damage or outdated software. What should I do?

Second, chewing gum

Gum is one of our favorite snacks. Chewing gum base is often spit on the ground at will. Because it is sticky, it is difficult to handle anywhere. We often find its footprints in streets, shops, school corridors, parks and other public places, and chewing gum residue has become an environmental pollution.

About 654.38+ten thousand tons of chewing gum are chewed all over the world every year, which is a very impressive figure. Chewing gum base is not afraid of acid and alkali and most organic solvents, and it is difficult to handle when it sticks to clothes. Ingredients of chewing gum: the main ingredient-synthetic gum; Plasticizer-diphenyl ethyl octyl phosphate; Filler-refined white rubber and solvent white wax; Stabilizer-calcium carbonate; Flavoring agent-starch, syrup, spice, powdered sugar.

Third, plastic products.

As a new material, plastic products have the advantages of waterproof, durability, low cost and light weight. Since it came out, it has been widely used in modern life and is well received by people. However, after people abandoned the discarded plastic products, they left a "white landscape" on the roadside, in the grass, in the streets and lanes, and in places where people lived and visited. To this end, environmental experts and people of insight loudly shout that if "white pollution" is not controlled and treated as soon as possible, it will bring irreparable disaster to mankind. "White pollution", as its name implies, is white pollution, which is just its original statement, that is, it refers to the pollution caused by white products such as lunch boxes to the environment. Later, people called the environmental pollution caused by plastics and other substances white pollution.

Plastic film can only be used once, and the residual film left in the ground affects farming, destroys soil quality, affects the absorption of nutrients and water by crops, and leads to crop yield reduction. Discarding waste plastic packaging anywhere can easily make animals sick or die. Once the plastic packaging garbage left in the water is eaten by seabirds, fish, etc. They will die of poisoning. The giraffe "seaside" in Shanghai Zoo died because of eating the plastic packaging of food thrown by tourists by mistake. When the veterinarian dissected its stomach, it was filled with plastic bags.

The impact of plastic products on the environment is not only the "visual pollution" caused by littering everywhere, but more importantly, the plastic itself is difficult to degrade. Once it enters the land, it will exist for a long time and accumulate over time. Natural substances, such as wood, metal, etc. Exposure to the environment can be swallowed or decomposed by microorganisms, or oxidized by oxygen in the air, and finally return to nature and participate in the material cycle on the earth again. But plastic is different. Take the packaging bag as an example, its raw material is 90% organic compound polyethylene, and 10% is starch extracted from corn. Even if the discarded plastic bags are buried underground, the bacteria in the soil layer can only eat 10% starch, but there is nothing they can do for most polyethylene, that is, they can't decompose or rot, so they can be said to be "immortal".

Fourth, the old mobile phone battery.

By 2003, there were more than 200 million mobile phones in China, and the number is increasing. The number of mobile phone batteries in China is also amazing, with the usage exceeding 300 million. If the life of each mobile phone battery is 2 years, where are the discarded mobile phone batteries that are eliminated every year? Obviously, most of them have become rubbish and have been abandoned.

Verb (abbreviation for verb) cheap battery

We often buy some cheap batteries while shopping. These batteries are cheap on the surface, but they are not economical because of their short service time. Waste batteries are disposable toxic wastes, and the use of cheap batteries is more harmful to the environment.

China is a developing country. At present, there is no factory that can handle waste batteries. China is also a big country in battery production and consumption. The annual output of consumer batteries exceeds 1, 7 1 billion, accounting for 1/3 of the world total. The population of China is less than 1/4 of the world population, but the battery consumption accounts for 1 of the world total. It turns out that many batteries produced in China are low in price, low in energy consumption and short in life, so there are so many waste batteries! In China, it is 17 1 100 million. ...
