Hazardous Waste Companies in Jiangsu, China (2026 Directory, 606 listed)

This directory collects 606 hazardous waste treatment, utilization and disposal enterprises within Jiangsu Province. The data is mainly derived from public information such as pollutant discharge permits, hazardous waste operating permits, and hazardous waste transfer manifests published by the ecological environment authorities of each city, compiled after manual verification. The directory is arranged by regions of Sunan, Suzhong, and Subei, and notes each enterprise's business category, approved operating scale, and main treatment processes, for the reference of waste-generating units, logistics service providers, and investment institutions when screening partners. Please note that public data may be lagging or have different update cycles; the actual operating status is subject to the latest announcements by the enterprise and the competent authorities.

3. How to verify these companies

To verify the qualification of a hazardous waste enterprise, you can perform the following steps in order: 1. Check the "Hazardous Waste Operating Permit" — enter the enterprise name under the "Hazardous Waste Management" section of the Jiangsu Provincial Department of Ecology and Environment website, and verify the approved hazardous waste categories (first eight digits of the code) and validity period, ensuring that the waste you declare is included and the permit is valid; 2. Check the pollutant discharge permit — on the public end of the "National Pollutant Discharge Permit Management Information Platform", verify the key management or simplified management category, and compare the permitted discharge amount and the performance report; 3. Review the environmental impact assessment (EIA) and acceptance approvals — require the enterprise to provide EIA documents consistent with the current process, confirming no major changes; 4. Through the "Jiangsu Province Hazardous Waste Full Life-Cycle Monitoring System" or the announcements of the local ecological environment bureau, check whether the transfer manifests for the last six months are normal, and whether there is any overdue storage or illegal cross-province transfer.

4. What to watch out for

There are three common pitfalls in hazardous waste procurement/cooperation: first, the "affiliation" qualification — the actual treatment facility does not match the address on the permit, and after transportation, the waste cannot be received; second, the "additional item" trap — although the enterprise's permit lists many categories, the actual equipment can only handle a few, and after overbooking, random blending occurs, leading to secondary pollution; third, the "low price" risk — when the treatment quotation is significantly lower than the market average, it is often accompanied by illegal activities such as illegal discharge or dilution to meet standards. It is recommended to conduct a site visit before signing a contract, request the receipts of the last three batches of manifests, and specify environmental protection liability for breach of contract in the contract.
