Frequently Asked Questions

CILA collects and regenerates clear waste oils: hydraulic, dielectric, whole cutting, quenching, mineral and industrial vegetable oils. Black motor oils are not part of our process.

Clear oils remain transparent or lightly tinted even after use. Black oils such as motor oils contain soot and metals — they belong to a different treatment stream.

CILA operates in mainland France, Belgium and Luxembourg. All our collections are carried out by ADR-certified hazardous materials carriers.

CILA operates from approximately 200 litres. Drums, IBCs, canisters or bulk tanks.
