techniques to address their waste generation. When wastes cannot be feasibly
reduced at the source, the Agency recommends recycling as the next best
option.
14.2 The quantity of chemicals purchased should be based on expected usage
during its shelf life and disposal cost of unused material. Actual reagent
preparation volumes should reflect anticipated usage and reagent stability.

laboratories and research institutions, consult "Less is Better: Laboratory
Chemical Management for Waste Reduction", available from the American

15.0 WASTE MANAGEMENT
15.1 The Environmental Protection Agency requires that laboratory waste
management practices be conducted consistent with all applicable rules and
regulations. Excess reagents, samples, and method process wastes should be
characterized and disposed of in an acceptable manner. The Agency urges
laboratories to protect the air, water, and land by minimizing and controlling
all releases from hoods and bench operations, complying with the letter and
spirit of any waste discharge permit and regulations, and by complying with
all solid and hazardous waste regulations, particularly the hazardous waste
identification rules and land disposal restrictions. For further information on
waste management consult the "Waste Management Manual for Laboratory
Personnel", available from the American Chemical Society at the address listed
in Section 14.3.
