| No. | Waste Material | Hazardous waste code | Production Segment | Hazard Characteristics | Whereabouts | Treatment process | Responsible Person |
| 1 | Waste diatomite | 900-041-49 | Hydrogen containing silicone oil and filter aids silica and siloxane for methyl phenyl silicone resin filtration | Filter additives contain adsorbed silicone oil and silicone resin, which pollutes the environment | Handled by a third party with receiving qualification | Landfill after incineration or collaborative disposal in cement kiln after incineration | Zhen Gu |
| 2 | Waste oil residue | 900-041-49 | In the hydrolysis process of hydrogen containing silicone oil, due to its high hydroxyl content, it can not be separated from water. After a certain event, hydroxyl condensation occurs, and silicone oil forms solid oil residue polysiloxane. | Leakage can pollute the environment | Landfill after incineration or collaborative disposal in cement kiln after incineration | ||
| 3 | Wastewater treatment sludge | 900-046-49 | Pressure filtration sludge of sewage treatment station | Surface-active substances, leakage can environmental pollution | Landfill or cement kiln collaborative disposal | ||
| 4 | Other categories | Waste thermal insulation cotton (900-032-36);
Waste silicone oil (900-041-49);
Waste packaging (900-041-49) | 1) Waste thermal insulation cotton: waste thermal insulation cotton obtained from pipeline removal during inspection and maintenance;
2) Waste silicone oil: unqualified products that do not meet the market demand during the experiment;
3) Waste packaging: damaged waste gas packaging (unable to be recycled), polysiloxane, hydraulic oil and oil contamination | Leakage can pollute the environment | Landfill after incineration or collaborative disposal in cement kiln after incineration |
