Date of Defense 2006-04-10 Availability unrestricted Abstract As new technology becomes available, consumers are likely to dispose of old equipment in favor the most upgraded electronics. It becomes increasingly difficult to manage electronic solid and hazardous waste when the lifespan of such devices is decreasing. In the computer industry, new technology demands that we upgrade software and eventually hardware on a consistent basis to avoid malfunction. Of particular concern are computer monitors, which contain 4-8 pounds of lead in the cathode ray tube. According to a study completed by Townsend et al, cathode ray tubes from televisions and computer monitors exceed the 5 mg/L leaching limit as set forth in the Environmental Protection Agency’s Toxicity Characteristic Leaching Procedure. The cathode ray tubes from these devices leached over 18 mg/L of lead. (1999) In the state of Florida most counties recycle computer monitors such that these toxic machines will not end up in the landfill where there is a potential for groundwater leaching. The cost for processing computer monitors is a burden to the landfill; therefore, this research minimized cost to the landfill through a linear programming approach using Microsoft Excel Solver. Using this program, an advanced disposal fee was imposed to residents within the state of Florida to alleviate the cost burden from the local governments. After using various scenarios to impose these fees, it was determined that the advanced disposal fee could be a partial solution to the funding issues for the counties. It does indeed assist counties in keeping these hazardous computer monitors out of the landfill and lower costs for processing these items with various recycling facilities.Files
