Environmental issues in pharmaceutical companies? Are there any good treatment techniques?
The question is too general, so it might be difficult for everyone to answer. Do you mean pharmaceutical companies as referring mainly to drug factories? Regarding environmental protection issues, there are different treatment methods for the three types of waste – which one are you referring to? Are there any specific examples?
Could you tell me what those three types of waste are?
It depends on what kind of product it is and on the composition of the wastewater; different wastewater types require different treatment methods.
Our company mainly produces cysteamine, anthranic acid, thiazolidines, and DEDS. Do you have any good methods for dealing with waste gas? The main issue is the odor.
The cheaper option involves sealing, negative pressure ventilation, and cleaning with acid, alkali, sodium hypochlorite, or hydrogen peroxide. A bit more expensive is exhaust gas incineration
Pharmaceutical waste gas is generated intermittently; the operation of furnaces used for incineration offers considerable flexibility, so manufacturers of such furnaces need to handle this carefully
We adopt the method of gas cleaning first and then incineration. . .
Medical waste gases are complex, containing both soluble and insoluble components; therefore, acid-base spraying alone is not sufficient for effective treatment. We use advanced oxidation in combination with spraying, which yields excellent results.
We first carry out gas washing, and then the exhaust gas is treated with an RTO; the downside is that the costs are too high, and smaller companies cannot afford it
