At present, domestic businesses such as laundry services, laboratories of schools and testing organizations, hotel laundry services, electronics companies and chemical manufacturers may generate waste containing toxic chemical substances (TCS). Inappropriate handling of TCS increases the risk of environmental contamination and creates human health concerns. The EPB has reinforced inspection and control to ensure that the companies are handling TCS according to regulations, and to prevent illegal import, manufacture, sale, use, storage, or disposal of TCS.

According to Article 18 of the Toxic Chemical Substances Management Act , in circumstances that call for the suspension of handling toxic chemical substances, one of four options are available: 1) return to original manufacturer or vendor; 2) sell or transfer to another party; 3) return to overseas exporter; or 4) disposal pursuant to the Waste Disposal Act. Upon confirmation of no alternatives to return, sale or transfer to other parties for reuse, before disposing of the TCS, the responsible party must inspect each batch and attach a TCS waste declaration along with a detailed chart to each batch, in addition to registering with local competent authorities. After obtaining approval of local authorities to dispose of the said TCS, the responsible party must follow relevant regulations in the Waste Disposal Act to prevent environmental contamination. The EPB calls on industry to be sure to apply for permits and make regular reports according to regulations, in addition to confirming treatment method of the said TCS.
