TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The substrate comprises sponge material, peat moss or oil-absorbent particulate. The peat moss comprises Sphagnum peat moss. The oil-absorbent particulate comprises kitty litter. The substrate is sand, coffee grounds, kitty litter and/or sponge. The bacteria are Pseudomonas and/or Bacillus.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Method: The step of operatively positioning comprises: positioning the VOC-absorbing material between an enclosure of the equipment and a breathing aperture to the atmosphere; positioning the VOC-absorbing material in a vent line between the enclosure and the breathing aperture to the atmosphere; or positioning the VOC-absorbing material in a trap operatively connected to a fluid line from the enclosure. The method further comprises: periodically replacing the VOC-absorbing material; and testing for leaking of the VOC from the enclosure to the atmosphere; after detecting an undesirable concentration of the VOC in the atmosphere in the vicinity of the breathing aperture; changing the VOC-absorbing material with fresh or re-generated VOC-absorbing material. The step of exposing the stripper of the VOC-absorbing material to bacteria comprises: after an undesirable concentration of the VOC is detected in the atmosphere in the vicinity of the breather aperture, exposing the stripper to the bacteria. Preferred Components: The fluid line is a drain line from the enclosure and the trap is connected to the drain line from the enclosure. The trap comprises: a liquid container defining a lower liquid chamber and an upper chamber for the VOC-absorbing material; a removable lid for accessing the upper chamber for the VOC-absorbing material; a fluid inlet line into the lower liquid chamber of the container adapted to be connected to a drain line from the enclosure; a fluid outlet line adapted to be connected to a drain line to fluid waste, where the fluid inlet and fluid outlet are positioned in the liquid chamber such that a liquid barrier can be maintained between the fluid inlet and fluid outlet; and a breathing aperture from the upper chamber, where any gases in the fluid from the fluid inlet pass through the VOC-absorbing material before being vented to the atmosphere.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The stripper comprises a glycol including monoethylene glycol, diethylene glycol, triethylene glycol or tetraethylene glycol. EXAMPLE - No suitable example given.
