Generally, there are three methods for destroying paper documents such as invoice destruction and receipt destruction:

1. Mechanical crushing;

2. Melt regeneration;

3. Incineration treatment.

4. Mechanical crushing: Use crushing machinery for crushing, and paper materials are turned into paper strips or into small fragments. For small batches of data, you can use your own mechanical crushing to keep the information from leaking out. Melting pulp regeneration: Melting waste paper into pulp again to regenerate new paper. It is applicable to general books, newspapers, cardboards and other materials that do not contain confidential information, and invoice receipts.

5. Incineration treatment: use a professional incinerator to incinerate the data (it is forbidden to incinerate in the open space at will in the urban area). It is applicable to the destruction of confidential invoice receipts, confidential information, and confidential invoice receipts under any conditions.
