for the
Laboratory Process

Following are a set of P2 options you may wish to implement. No option is perfect for everyone, but sometimes options that have worked at one facility can work at yours. They might also serve as inspiration.

Reviewed Laboratory Options

Following are a list of options that have been reviewed by pollution prevention specialists. These options have worked at other facilities and may work at yours.


Reduce chemicals

Scale down the amount of chemical used in experiments.

Replace wet tests

Replace wet tests with analytical instrumentation.

Incorporate product samples

Return unused samples to the process unit for product incorporation.

Install distillation units

Install distillation units to recycle chemicals, for example, alcohol, xylene, formaldehyde, and so forth.

Acid/Base Experiments

Use vinegar/ammonia instead of Hazardous Acids/Bases

Replace Mercury Thermometers

Use Digital Thermistor/Thermocouple instead for High temperature measurements (for lower temperatures a less expensive alcohol thermometer will suffice)

Glassware cleaning

Use Potassium Hydroxide Sonic Baths Specialty Solvents instead of Chromic Sulfuric Acid solutions or Alcoholic Potassium Hydroxide

Phase Change/Freezing Point Depression

For these experiments use Acetamide instead of Stearic Acid.

Quantitative Test for Halide Ions

For these experiments use Cyclohexane instead of Carbon Tetrachloride.

Return Samples

When retention time for samples are up, collect them in segregrated drums and return to customer or vendor.

Purchase non-mercury Thermometers

Establish a laboratory purchasing procedure to ensure only non-toxic thermometers are purchased.

Smaller Squeeze Bottles

Reduce the size of squeeze bottles to minimum size practical (i.e., use one pint instead of one quart). Human nature being what it is, personnel reduce the volume of solvent used as the bottle gets close to being empty in order to avoid refilling the bottle.
