3. How to verify these companies

To verify the qualifications of hazardous waste enterprises, you can start from the following aspects: 1. Check the 'Hazardous Waste Operating Permit'. On the official website of Zhejiang Provincial Department of Ecology and Environment, under the 'Approval Publicity' or 'Data Center' columns, search for the enterprise name, and verify the approved waste categories, codes, operating scale, and validity period. 2. Check the 'Pollutant Discharge Permit'. Enter the enterprise name on the National Pollutant Discharge Permit Management Information Platform (public access), confirm whether it holds a permit, whether it is within the validity period, and view the main pollutant emission indicators. 3. Check environmental penalty records. Search the enterprise name on platforms such as 'Credit Zhejiang' or 'Qichacha' to see if there are any adverse records such as 'environmental penalty' or 'order to make corrections'. 4. Check hazardous waste transfer manifests. You may ask the enterprise to provide recently executed manifests to verify whether its actual disposal capacity is consistent with its records. 5. Conduct on-site inspection. Check whether the hazardous waste storage facilities, signs and labels, metering equipment, etc. conform to regulations, and verify whether the types of waste entering the site match the permit.

4. What to watch out for

When selecting hazardous waste enterprises, the following points should be noted: First, hazardous waste code matching. Ensure that the permit covers all waste categories and codes you generate, to prevent unqualified acceptance. Second, region and transportation. Some enterprises are limited to collecting hazardous waste only from their own region. Cross-provincial transfer procedures are cumbersome, so the transportation radius and cost need to be confirmed. Third, the low-price trap. Excessively low quotes are often accompanied by hidden fees or illegal disposal. Be sure to calculate the full process cost. Fourth, contracts and manifests. When signing a contract, clarify the responsibilities for waste handover, loading/unloading, and transportation, and require a compliant transfer manifest for each batch to avoid joint liability for environmental risks.
