Burying is actually a very irresponsible practice. Although there will be no problems at the time, over time, the buried harmful substances will be released and cause environmental pollution.

The garbage leachate is oxidized through electrolysis and catalysis, and then biochemically treated.

It must be disposed of harmlessly. There is a practice abroad that stores items that cannot be disposed of at the moment in containers until there is a way to dispose of them.

It’s shocking why the news hasn’t reported it. I’ve seen news broadcasts reporting on similar chemical waste disposal. The landfill must be carried out by specialized companies, and the location must be chosen carefully. It must be sealed in special containers and then buried. But burying it isn’t a good idea either. I’d better think of a better way.

The landfill should be treated with geomembrane to prevent seepage, and flood interception measures should be taken around the site!!!

Leachate from landfill waste should be treated strictly.

Depending on the degree of toxicity, ordinary solid waste salt is acceptable. Organic substances, especially those that are toxic, are not allowed and can be disposed of by incineration.

Of course, chemical waste cannot be buried. This is a transfer of pollution, and it is a time bomb. No one knows when it will explode. It can easily trigger mass incidents, so this is also an extremely irresponsible approach. Chemical waste is generally incinerated to make it harmless.

The main garbage disposal methods used in our country now are landfill and incineration. 75% of the garbage is landfilled. Landfilling occupies a very large area. It is not an ideal garbage disposal method in the current situation of increasingly tight land resources. It will also produce a large amount of garbage permeate. If it is discharged or overflows without treatment, the consequences will be disastrous. Especially as mentioned above, the situation is more serious near above-ground waters. Although incineration can reduce waste by 90%, the incineration process will produce a large amount of highly toxic dioxins, which will pollute the air and water, and there will be incineration ash, which needs to be solidified and then landfilled. Therefore, so far, there is no technology that can effectively and environmentally friendly waste disposal.

There is no way, our factory's chemical waste is basically landfilled. For example, waste acids, waste alkali, and waste catalysts are all landfilled in nearby barren hills. It can be said that these are all time bombs. I don't know if they will cause environmental pollution accidents that day!
