Using less, reusing items and buying recycled content products are all part of green purchasing (environmentally preferable purchasing). The LFUCG purchases energy efficient computers and office equipment, LED EXIT signs, LED scoreboards and programmable thermostats, low mercury content (green tip) fluorescent bulbs, recycled content paper towels and tissue, non-treated lumber, furnaces with a 90% or higher efficiency rating, 13 SEER (Seasonal Energy Efficiency Ratio) air conditioners, and water-based traffic marking paint. We also began a new initiative in 2007 to buy 30% post consumer recycled content paper as our “default” paper for printers and copiers. The LFUCG uses approximately 3,000 cartons (15 million sheets) a year of copy paper and making the switch to recycled content paper reduced the amount of wood required to produce this paper by 83 tons, the amount of energy required by 398 million BTU, the amount of greenhouse gases generated by 50,000 pounds, the amount of wastewater generated by 208,000 gallons, and the amount of waste by 27,000 pounds annually. Additionally, the LFUCG reuses many items including using empty traffic marking paint barrels for asbestos and lead abatement, metal street signs as blanks for new street signs, and crushed glass from the Recycling Center for landfill closure activities. Finally the LFUCG also took steps to reduce the number of printers in the Government Center, Police Headquarters, the Phoenix Building and the Switow Building from 527 to 127 (a 75% reduction) which saves resources.
