People produce a lot of domestic garbage in daily life. Every day, domestic garbage is thrown into garbage bins, and then transported by sanitation workers to landfill sites for incineration and combustion, or sent to garbage recycling centers for plasma gasification. But in fact, garbage disposal is not simple, and it is an indispensable link in modern human life.

Have you ever wondered where the black garbage bags will be shipped out of the house? Waste management is a global problem. Any country on the planet is faced with the thorny problem of garbage disposal. According to statistics, the average American inhabitant produces 4.4 pounds of garbage per day. Surprisingly, industrialized countries consume 75% of the global paper supply, but these countries account for only 16% of the global population!

Ironically, as the country’s urbanization process continues to increase, the amount of waste is also increasing, which means that people need more paper, a lot of consumer product packaging waste, newspapers and magazines, disposable plastic materials, diaper waste, etc. in cities. Areas generate 2-3 times more waste than rural areas.


Landfill, as its name implies, is landfilling away from residential areas. However, the landfill must be rationally planned to avoid hazardous waste from polluting the environment. The landfill mainly deals with solid waste and is carried out according to the type of waste. Precise classification

Municipal landfills are used to treat domestic household waste, bioreactor landfills are used to treat organic waste, and industrial landfills are used to deal with commercial and industrial waste.

The construction demolition landfill mainly deals with construction waste, which mainly comes from house demolition and construction, bridges, and renovation projects. The waste includes: metal, heavy materials, glass, concrete, and wood.

The Coal Combustion Residue Landfill (CCR) is dedicated to the disposal of waste from coal combustion.

Hazardous landfills are mainly used for hazardous waste, such as batteries, coatings, combustible liquids and other chemicals, fluorescent lights, motor oil, etc.

Incineration is a heat treatment method for treating garbage. The garbage is incinerated at high temperature and uses the generated energy to generate electricity. However, in the process of treatment, the garbage is first removed by high temperature combustion toxins, so that the release of gas to the atmosphere will not cause damage to the environment.

Waste incineration is particularly common in Japan because of the scarcity of land resources in Japan, which cannot occupy too much land for landfilling. Incineration can reduce 95% of waste and greatly reduce landfill waste. At the same time, incineration is particularly suitable for hospital waste and sewage waste.

Plasma gasification

Plasma is a very high-temperature, charged gas. They can generate electricity, so it is also called the “fourth state of matter.” Plasma naturally exists in lightning and gas on the surface of the sun. Plasma gasification is the Westinghouse plasma in the United States. A new technology for urban and industrial waste treatment developed by the company. Like incineration, plasma gasification can reduce the number of landfills, but instead of burning waste waste like incineration, it directly converts organic waste into gas. Compounds and inorganic waste are stored in a crystal called slag.

3R treatment: reduce use, reuse and recycling

Reduce the use: Before the garbage is accumulated, the first thing to do is to stop or reduce the use so as not to generate garbage as much as possible. Therefore, reducing the use of resources is the first step in waste treatment. People should not make garbage as much as possible so that people do not have to destroy resources. And dispose of it. Reducing the waste of resources can save billions of dollars for a country. To do this is simple. Use resources according to people ’s needs, not people ’s wishes. Buy only the necessities of life, buy high-quality goods, and do n’t indulge in “ Fast Fashion “, using the least amount of packaging possible.

Reuse: For some people, trash can be a “treasure”. People often think that waste items are useless, destroyed, and disgusting. Do you remember when teachers at school made students use waste products to make them beautiful? , Creative items? In order to protect the environment, people should integrate their creative designs into waste items so that they can be reused and give new use value, such as: packaging materials can be reused, and reusable cloth bags are usually carried instead of buying each time they go to the store Plastic bag.

Recycling: newspapers, plastics, aluminum, and cardboard can be recycled. Recycling is an industry. To make something from recycled products, a new manufacturing industry must be established, which will create more employment. opportunity. According to preliminary estimates, a landfill that handles 10,000 tons of waste can provide 6 employment opportunities. However, 10,000 tons of waste recycling can create 36 jobs. Recycling can be performed at home. People only need to extract and recycle the waste. For materials, there are currently treatment centers set up specifically for recycling garbage, where people can place the recycled materials there for proper disposal.

Some countries need to invest billions of dollars to dispose of garbage. This is a thought-provoking and startling issue. At the same time, governments need to allocate large amounts of land, set up factories to handle human-made garbage, and do their best to maintain the earth’s green environment.
