29 Waste and Recycling Fluorescent Lamps Fluorescent lamps are gathered by custodial and maintenance personnel and transported by Central Stores to EHSSB where they are shipped by a contracted vendor for recycling. Ignitable Solvents Hazardous waste solvents are segregated by BTU and halogen content. Solvent streams with high BTU and a low percentage of halogens are burned as fuel. Oil Used oil is collected separately from other materials, such as solvents and antifreeze. It is then recycled by a contracted vendor. Reduction/Substitution In addition to recycling efforts, campus users may minimize the amount of hazardous waste generated by reducing the amount of materials purchased or by substituting less hazardous items. Batteries Campus users are encouraged to purchase rechargeable batteries instead of alkaline batteries. Down-scaled Laboratory Experiments • Microscaling - Some laboratory procedures can be modified to minimize the amount of waste generated. When possible, teaching laboratories should consider microscale experiments. The Department of Chemistry has recently revised many teaching lab procedures to include microscale experiments. Laboratory procedures should be reviewed periodically to identify areas for waste minimization. • Down-sizing analytical equipment can also reduce waste. As an example, the scaled-down Kjeldahl units now readily available significantly reduce the amount of corrosive and toxic wastes produced. The benefits of microscaling include less chemical use, lower costs, less time required for experiments, reduction in chemical exposure, less time required to heat/ cool smaller volumes, and less release of volatile to the air. Equipment or Technology Modification Instrumental analyses, suchas gas chromatography, spectroscopy and nuclear magnetic resonance, require minute amounts for quantitative determinations as opposed to more traditional
