31 Waste and Recycling Light Bulbs Users are encouraged to replace incandescent bulbs with longer- lived, energy efficient, and recyclable fluorescent and LED bulbs. Non-chlorinated Degreasers Naphtha, diesel fuel, or organic degreasers should be used in place of trichloroethane, tetrachloroethylene, or chloroform. Used non-chlorinated degreasers may be used as fuel or recycled. Non-halogenated Solvents When possible, substitute non-halogenated solvents for those containing chlorine, bromine, or fluorine. Used non-halogenated solvents may be blended for use as a fuel. Non-mercury Thermometers and Equipment Mercury is toxic and damaging to the environment, and is still one of the most frequently spilled materials on campus. Substitutes are available for mercury-containing thermometers and manometers such as alcohol or glycol thermometers, bimetal and stainless steel thermometers, thermocouples, pressure transducers and other electronic temperature devices. If mercury thermometers must be purchased, invest in the Teflon-coated type that contain the mercury if the capillary is broken. For existing equipment, spill protection (trays or pans) should be used.
