How should butadiene-containing waste liquid be treated?
Thread Content
The company uses butyl acetate in its production; it is considered a chemical substance that can be used to manufacture drugs, and purchases of this substance are registered with the public security authorities. It was handled in full accordance with **the regulations**. Then, during use, our Ding Tong is applied in a cyclic manner. When the recycled butane contains too many other impurities and is not up to standard, we carry out distillation to extract as much butane as possible. This will leave a residue at the bottom, which is quite sticky and thick. The composition of this residue is quite complex, containing various organic solvents, resins, water, as well as finished and semi-finished products; the butane content in it is 10%, or even lower. All along, we have been transferring this material as hazardous waste to qualified disposal companies here for incineration. But now, an aunt from the administrative department went to attend a meeting; upon returning, she said that this is waste material of that type, and it must be handled by a disposal company qualified to deal with such waste, and registration with the police authorities is also required. Then, I checked the relevant laws and regulations – the **Regulations on the Management of Precursor Chemicals issued by ***, the **Measures for the Licensing of the Production and Operation of Non-pharmaceutical Precursor Chemicals issued by the State Administration of Work Safety**, as well as Jiangsu’s **Detailed Rules for the Licensing of the Production and Operation of Non-pharmaceutical Precursor Chemicals in Jiangsu Province** – and none of them specify how to handle residues like ours. So I would like to ask how such residues are actually handled, and what is the basis for that? If it’s really necessary, then a disposal company with the qualifications to handle waste parts must be found. Then we will definitely go look for it. However, after contacting several hazardous waste disposal companies, either they did not have the necessary qualifications or they had never even heard of such a thing. So now I seriously and genuinely doubt whether that aunt misheard during the meeting Or was it misunderstood? Thank you all! I’m scratching my head right now~~~
Disposal and transfer of solid waste: The Ministry of Environmental Protection has recently issued clear regulations stating that it is necessary to register with the local environmental protection agency, public security bureau, and health department at the appropriate time, and go through the relevant procedures before such solid waste can be transferred, used, or disposed of. The regulations and management of hazardous waste are more stringent. For specific details, you can consult and handle the matters at the local environmental protection agency.
Yeah! Thank you to the friend above; to add, when we transfer hazardous waste, we follow the regulations set by the Environmental Protection Agency, and there are transfer documents available!
It is likely that there are no companies specialized in handling such cases; your current process is completely correct. Don’t listen to the scare tactics up there.
I guess what they referred to during their meetings, or what the higher-ups said, as “fei ding tong” is probably a type with a relatively high content of that substance – for example, one with a ding tong content of 50 to 60 – and it’s not a type whose composition is very complex. Rather than saying something like our kind of residues. It seems the aunt from the administrative department misunderstood things. It’s also our fault for continuing to call this residue \"Waidingtong\"; it appears we need to change the name used internally, including the names for various records as well. Otherwise, we’re just creating trouble for ourselves. If someone from higher up comes to check the records, it’s fine if there’s a leader who can provide a satisfactory explanation; but it becomes problematic when dealing with a leader who can’t come up with an explanation.
