Article 7
In treating hazardous waste materials, toxic containers, hazardous gases, dust, wastewater, biological components and other hazardous components or materials, Chinese herbal medicine factories shall act not only in accordance with relevant laws, but also with the following principles:
(1) For hazardous waste materials and toxic containers, storage facilities shall be established, and these materials and containers shall be decomposed in accordance with their properties, and then appropriately incinerated or buried. If toxic containers are to be reused, they shall be washed and rigorously controlled, and may not be used to hold food products.
(2) For hazardous gases and dust, airtight facilities, local exhaust ventilation systems and negative pressure procedures shall be established; these substances shall, in accordance with their properties, be scrubbed, collected, oxidized, reduced, combusted, or otherwise appropriately treated. If exhaust gas contains dust, it shall first be subjected to centrifuging, filtering, scrubbing, or some other form of dust-removal processing; the emission of such gases must comply with air pollutant emission standards.
(3) For the processing of wastewater, impermeable storage pools shall be established, and acidification, alkalization, neutralization, active carbon adsorption, or other effective methods shall be used to break down or remove wastewater toxins; the release of wastewater must comply with water release standards.
