NMP waste disposal

NMP is a colorless and transparent liquid with extremely strong solubility and volatility. As one of the main raw materials in the lithium-ion battery manufacturing process, NMP directly affects the slurry coating quality and environmental protection requirements of lithium-ion batteries.

According to industry research data analysis, although differences in models and specifications will lead to different proportions of NMP in the value of lithium-ion batteries, overall, NMP accounts for about 3%-6% of the manufacturing cost of lithium-ion batteries. The market for NMP The scale and demand are also growing with the growth of lithium-ion batteries, especially energy storage batteries and power batteries.

NMP can also be used as a solvent for battery recycling and reuse. There are also valuable materials in used batteries, such as lithium, cobalt, etc.

Using the solubility of NMP, materials in used batteries can be dissolved, and these materials can be recycled and reused through subsequent extraction and purification processes.

We need to pay attention to storage and handling. Store N-methylpyrrolidone in a dry, well-ventilated place away from sources of ignition and oxidizing agents. During treatment, dust and haze should be avoided, and care should be taken to avoid mixing with other chemicals.

We need to dispose of waste correctly. Properly dispose of used N-methylpyrrolidone as hazardous waste. Please ensure correct waste disposal in accordance with local regulations and environmental protection requirements to reduce environmental impact.
