Abstract:
Pharmaceutical manufacturing industry is one of 12 key industries to be treated in the national environmental protection plan. About 80% of the pollution is caused by the production of chemical raw drugs. The hazardous wastes produced by chemical raw drugs possess the hazardous characteristics of toxicity, flammability, corrosiveness, chemical reactivity, infectivity and leaching toxicity, etc., which has great potential harm to the ecological environment. Starting from the process of fermentation pharmacy, chemical synthesis pharmacy and extraction pharmacy, the generation and hazard properties of hazardous wastes in each link were summarized, and the current situations and existing problems of their utilization and disposal were analyzed. The countermeasures and suggestions on the utilization and disposal of typical hazardous wastes were put forward as follows: 1) reducing environmental risks in the source, 2) improving the level of cleaner production in the process, 3) enhancing the resource level of hazardous waste in the end use of pharmaceutical manufacturing industry.
