I’m a bit confused about the understanding of hazardous waste and solid waste.
Thread Content
According to the \"General Principles for the Identification of Hazardous Wastes\" GB5085.7-2019, \"Items that do not belong to solid waste are not considered hazardous waste.\" The same standard states that \"solid waste refers to solid, semi-solid substances, as well as gaseous substances contained in containers, which are generated in production, daily life, and other activities and have lost their original utility value; or although they have not lost such value, they are discarded or abandoned. It also includes items and substances that are required by laws and administrative regulations to be managed as solid waste.\" According to the \"List of Wastes,\" \"Solid waste (including liquid waste) that falls under any of the following categories is included in this list.\" In other words, liquid waste can also be classified as hazardous waste; it can be inferred that only by including liquid waste within the scope of solid waste management can all the above points be reconciled. Please share your opinions
Solid waste refers to solid waste or solid-form waste; those contained in solid containers are also considered such. As for liquid waste, which literally refers to waste in liquid form, the issue lies in the fact that only waste classified as solid waste may be considered hazardous waste; does that mean waste that is not classified as solid waste is not hazardous waste? So, can it be understood as waste liquid that has been placed in a fixed container, with no value for recycling, classified as liquid waste? And since it’s in a solid container, it’s managed as solid waste… It’s purely a distorted interpretation; the original poster is confused, I guess
My understanding is that \"liquid waste included in solid waste management\" falls under \"hazardous waste\".
Are there any management systems for hazardous waste storage in the chemical industry?
Things like waste liquids and distillation residues are also considered waste liquids; the ‘List of Hazardous Wastes’ specifies which ones fall under the category of hazardous waste. However, such liquid waste is an exception; as stated in the \"General Principles for the Identification of Solid Waste,\" waste that can be sent to wastewater treatment plants for processing and discharged in compliance with standards does not fall under the category of solid waste.
Hazardous waste is definitely solid waste, but solid waste is not necessarily hazardous waste. Liquid waste is considered hazardous waste as long as it is listed in the hazardous waste catalog or has been tested and found to possess the characteristics of hazardous waste; in such cases it is managed as hazardous waste.
