According to the 2021 National Hazardous Waste List, waste mineral oil and waste packaging contaminated with mineral oil generated during production, sales, and use belong to the HW08 category of hazardous waste (hazardous waste code 900-249-08), such as waste machine oil drums, lubricating oil drums, etc; This production line system is designed for the recycling and disposal of hazardous waste HW08 type machine oil pots. According to the classification requirements in the National Hazardous Waste List, waste packaging containers such as oil pots containing or contaminated with mineral oil are classified as HW08 industrial hazardous waste. It does not belong to general solid waste or industrial waste, and its collection, storage, transportation, and disposal must comply with the relevant requirements of the Solid Waste Pollution Prevention and Control Law of the People's Republic of China. Therefore, compared with traditional solid waste treatment, this system has essential differences in terms of process rigor, overall sealing, and zero manual intervention throughout the process.

The main units of this production line system are:

1. Initial crushing pretreatment;2. One residual harmless collection;3. Fine crushing+secondary residual harmless collection (or destruction);4. Strong cleaning and decontamination;5. Dehydration and drying.
