Included are methods and systems for recycling a gas emitted from non-aqueous cleaning. An example method includes contacting a contaminated equipment with a non-aqueous cleaning material; wherein the spent non-aqueous cleaning material emits the gas. The method further comprises capturing the emitted gas, filtering the emitted gas, and recycling the emitted gas into the non-aqueous cleaning material.
