What surprised these reporters was far more than that. On the streets, you will see green vehicles with flashing work warning lights. These are sanitation work vehicles, and they come in different sizes. Large ones include sprinklers, garbage removal trucks, fog cannon trucks, street washing trucks, etc., while medium-sized environmentally friendly vehicles include street sweepers, street vacuum trucks, etc. As for small vehicles, they are even more diverse, such as ground sweepers on the sidewalks on both sides of the road, mobile garbage trucks, high-temperature and high-pressure sewage cleaning trucks, etc.

Of course, such a rich family of sanitation vehicles is not the focus of these media reporters. What they are concerned about is that most of these sanitation vehicles are unmanned vehicles. Only a few large vehicles have sanitation workers wearing sanitation overalls, and they are engaged in light work.

You will also occasionally find some sanitation workers wearing sanitation work clothes on the streets. They do not clean the floor like traditional sanitation workers. Instead, they hold control equipment and operate the sanitation equipment to make up for the shortcomings of these intelligent and unmanned equipment. insufficient.

It is also because of the 24-hour non-stop operation of these unmanned sanitation vehicles that the streets of Anxi are very clean, with no trace of dust or garbage at all. Even if there is garbage, it will be cleaned up in a short time.

Such a scene really shocked all the foreign media reporters. In their view, this distant eastern city could be so advanced, as if it had entered a future city that could only appear in movies and TV series, and other cities on the earth. The places are completely two different worlds.

Everything here has a very close relationship with Haoyu Technology in this city. It can be said that it was Haoyu Technology and Wu Hao that changed this city.

It's still some time before Haoyu Technology's summer new product \u0026 new technology launch conference, so these reporters decided to go deep into every corner of the city to explore everything related to Haoyu Technology.

So these foreign media reporters began to look for interviewees they were interested in based on their own interests. In this regard, Anxi City is also very happy to show these foreign media reporters the development results of Anxi in recent years. On the one hand, it is to show overseas the development results in recent years, and on the other hand, it is also to change the overseas media and people’s perception of our country and Anxi. some biased views.

Under the leadership of the publicity department staff, these media reporters naturally saw a lot of things they had not seen before.

For example, in the environmental protection system, the unmanned environmental protection vehicles they see on the street are just a basic link in the entire city's intelligent environmental protection engineering system.

For a large city, a huge amount of solid waste is generated every day, reaching thousands or even tens of thousands of tons. How to deal with this waste has always been a controversial topic.

There are three main methods for solid waste cleaning used by most countries and cities.

First of all, the first one is to recycle the renewable resource waste. However, in this regard, the recycling rate of this part of garbage in various countries has always been very low. Only a rough screening will be carried out, some valuable garbage will be recycled, dismantled, processed, and then used for resource utilization. However, this utilization rate is a very small part of the total amount of garbage, and can even be said to be negligible.

As for European and American countries, they are doing even better in this area. They concentrate a lot of large solid waste. However, instead of recycling and reusing, they packaged and transported them to third world countries and handed them over to these countries for dismantling and digestion, which is equivalent to free disposal of these solid wastes for them. It is tantamount to forcing the garbage it produces onto other countries, causing serious pollution to these countries and regions.

In the early years, we were also the exporter and processor of garbage from these countries. Later, we realized the dangers of these foreign garbage, so we banned the entry of these foreign garbage. So these countries, after cursing a few words, can only find other countries and regions, such as Southeast Asia, Africa, South America, etc. Judging from the exposed photos and news, areas in some countries are already filled with solid waste from all over the world, and even garbage mountains thousands of meters high have become a sea of ​​garbage.

Although all countries are now advocating to strengthen the recycling and reuse of solid waste, the actual recycling rate is too low, which can be described as a piece of cake.

The second way is centralized burial, which is also the most important and main way to deal with solid waste. There are such large landfills around many cities, and large amounts of municipal solid waste are transported here every day and then buried.

Although these landfills have undergone special treatment, over time, rainwater penetration will cause harmful elements in these garbage to contaminate nearby groundwater, harming the surrounding ecological environment and human health. These buried garbage need to go through a long degradation period, which may take hundreds, thousands, or even tens of thousands of years before the earth can metabolize it.

The third method is centralized incineration. This is an ancient method of garbage removal, and it is also a new method of garbage removal that has been actively developed in various places in recent years.

In the early years, centralized incineration was carried out to deal with this waste. But at that time, the knowledge was burned on the spot, and other things were not taken into consideration at all. The harmful gases produced by the incineration of these garbage can seriously pollute the entire air and even easily cause some respiratory diseases. As for the ashes after incineration, they are also polluting. They will penetrate into the ground with rainwater and pollute groundwater. They will also collect into rivers with rainwater and pollute water sources.

People quickly realized this, and then carried out centralized incineration, concentrated it in special devices for incineration, filtered the air after incineration, and processed the incineration ash, so as to reduce pollution.

In recent years, with the strengthening of environmental protection concepts, especially the depletion of carbon emissions and mineral resources. People are beginning to notice that these garbage are actually a resource that can be used. In the past, these garbage were burned in vain, which is a pity.

Why not use these garbage to incinerate and generate electricity? This is much more environmentally friendly than those thermal power stations that just burn coal.

So various cities began to build some thermal power plants around them specifically for burning garbage. Such thermal power plants can process a lot of garbage every day and convert them into electricity to continue to serve the city. Some cities even use the heat energy generated by garbage incineration to provide heating for urban residents.
