1. A method of removing and separating gaseous anesthetics from a waste anesthetic gas stream to prevent atmospheric venting of gaseous anesthetics from a healthcare facility, said method comprising the steps of:

  • collecting said waste anesthetic gas stream from an anesthetizing machine (12A, 12B, 12C), compressing said received waste anesthetic gas stream to a pressure above atmospheric pressure using a compressor (42) with at least one compression stage, cooling said compressed gas stream by passing said compressed gas mixture over a cooling surface (136, 236A, 236B) characterized by a surface temperature gradient such that said gas stream passes thereover in a direction from a warmer to a colder temperature, condensing said gaseous anesthetics from said compressed gas stream, separating said condensed anesthetics from said compressed gas stream, venting to atmosphere (46) said gas stream absent said condensed anesthetics.
