Hazardous Waste Companies in Sichuan, China (2026 Directory, 150 listed)

This directory includes 150 enterprises in Sichuan Province involved in hazardous waste business activities, covering different operating methods such as collection, storage, utilization, and disposal. The information is compiled from public sources: public notices on the issuance of hazardous waste operating permits by ecological and environmental departments at all levels, the National Pollutant Discharge Permit Management Information Platform, the enterprise environmental information law-based disclosure platform, public information from the National Solid Waste Management Information System, and administrative penalty and credit disclosure records. It is suitable for environmental protection and procurement personnel at waste-generating units to screen partners, and also suitable for industry peers to understand the permit distribution in the region. The directory only provides leads and does not constitute a qualification guarantee. Before formal cooperation, please verify independently through official channels.

3. How to verify these companies

1. Check the Hazardous Waste Operating Permit. Search under the solid waste or administrative licensing public notice columns on the official website of the Sichuan Provincial Department of Ecology and Environment, verify the permit number, issuing authority, and validity period, and focus on whether the approved operating method (collection and disposal are very different) and the approved waste category codes cover the HW code you need to deliver. 2. Check the Pollutant Discharge Permit. Query the National Pollutant Discharge Permit Management Information Platform by name or unified social credit code to see whether a permit is held and whether the industry category corresponds. 3. Check environmental information law-based disclosure. Check whether there is an annual report and self-monitoring data on the provincial disclosure platform. 4. Check penalties and credit. Check Credit China (Sichuan), the National Enterprise Credit Information Publicity System, and administrative penalty disclosures by ecological and environmental departments to see the operating status and whether there are environmental penalties. 5. For cross-province transfers, confirm whether the National Solid Waste Management Information System electronic transfer manifest can be used.

4. What to watch out for

Common pitfalls: treating enterprises with only collection qualifications as disposal parties, leaving the final destination of the waste unclear; permits expired or codes mismatched, so even if the goods are accepted they cannot be handed over onward; middlemen passing goods through multiple hands, with quotes noticeably below market, so be alert to the risk of illegal dumping, and waste-generating units still bear liability. Transfers must use electronic manifests; private transactions have no legal documentation, and if something goes wrong it is difficult to prove oneself. Before signing, clearly write out the waste code, handover method, manifest responsibility, and default clauses; do not compare only on price.
