Løsemiddelgjenvinning

Løsemiddelgjenvinning refers to the process of recovering and reusing solvents that have been used in various industrial processes. The aim is to reduce waste, lower environmental impact, and improve economic efficiency by reclaiming valuable chemical feedstocks. In a typical recovery operation, used solvents are first separated from solids and impurities through filtration or sedimentation. The solvent-containing liquid then undergoes distillation or stripping to remove solvents and other volatile components. Advanced techniques such as adsorption, membrane separation, or cryogenic distillation may be employed to enhance purity or to handle solvents with close boiling points. Once purified, the recovered solvents can be returned to the production line or sold as a raw material, thereby closing the loop in a circular economy framework.

This practice is widely implemented in industries such as paint manufacturing, plastics, pharmaceuticals, and electronics, where solvent usage is significant. Regulatory frameworks in many regions, including the European Union, mandate proper handling, treatment, and reporting of solvent emissions. Environmental benefits include reduced greenhouse gas emissions, lower pollution of water bodies, and lesser reliance on virgin solvent production. Economic advantages stem from cost savings in raw material and waste disposal. Standard operating procedures and continuous monitoring are essential to ensure safety and compliance. Overall, løsemiddelgjenvinning represents a critical strategy in sustainable industrial operations and the management of chemical resources.
