Mineral-based cutting fluids for machining that do not contain halogens (code 12 01 07*) are generated during turning, milling, drilling, and other metalworking operations.
These fluids reduce friction, cool the cutting zone, and protect tools; however, after losing their operational properties, they become classified as hazardous materials.
Hazardous waste management for this type is based on analysis of the mineral base, the level of contamination with metal particles, and oxidation products.
Handling hazardous waste in the form of spent cutting fluids requires control, as they may have toxic effects and negatively impact the production environment.
Hazardous waste storage is organized taking into account the physical and chemical properties of the fluids and their tendency to separate or form sediments.
Key storage conditions include:
- use of sealed containers resistant to mineral oils;
- protection from temperature fluctuations and direct sunlight;
- prevention of mixing with other process fluids.
Hazardous waste transportation for this category is carried out considering fluid viscosity and the risk of leaks during movement.
During transport, it is necessary to ensure:
- complete container tightness;
- secure fixation of containers within the vehicle;
- continuous visual monitoring of container condition.
Hazardous waste processing of cutting fluids is aimed at controlled purification and reduction of hazardous properties of the components.
Within environmental services for enterprises, systematic tracking of fluid volumes withdrawn from use at different production stages is essential.
A well-structured operational system helps prevent accumulation of spent mineral fluids in production areas.
Special attention is given to training personnel working with these materials, as improper actions may lead to contamination of equipment and work surfaces.
Internal regulations must take into account the properties of the mineral base and the products of its degradation during operation.
Controlled handling of this type of hazardous waste is an important component of industrial safety systems.
Comprehensive management of halogen-free cutting fluids supports stable operation of metalworking enterprises and reduces environmental impact.
