Spent NMP Distilled and Redistributed
US Ecology offers a recycling program to manage spent N-Methyl-2-Pyrrolidone (NMP), a non-hazardous solvent used in the lithium-ion battery manufacturing process. NMP is used to dissolve nickel, manganese and cobalt (NMC) powder. Once the NMC powder has been released onto the electrode plates, the material is cooled, condensed and collected as a waste by-product. Battery manufacturers may use 10,000 - 20,000 gallons of NMP per month.
We receive spent NMP solvent from battery manufacturers in bulk and non-bulk packages. Our pick-up service includes tank telemetry monitoring and volume tracking to automate the process. It is then distilled into an industrial grade product that we market and redistribute. Our distillation process returns the highest quality end product, allowing us to guarantee consistent specifications to the clients we supply.
The key benefits of US Ecology's spent NMP Recycling program include:
- Tolling Services
- In-plant Management
- On-site Distillation Services
- R&D and Quality Control Experts
- Tank Telemetry Monitoring
- Waste Pick-up
US Ecology has over 20 years of experience in the distillation and recycling of solvents such as NMP.
