Pollution Prevention/Source Reduction
Pollution prevention means not generating waste in the
first place by reducing, eliminating, or substituting it at the source.
P2 focuses on source reduction and is the highest goal to strive for.
“just in time” purchasing for chemicals. Buy only quantities of
supplies that you will be able to use within 1-2 years. Avoid
bulk-sized purchases – the money you save initially will be far outweighed
by disposal costs and procedures at the end!
and use non-hazardous (or less hazardous) alternative chemicals when
that future purchases of equipment include the disposal costs of old
equipment that is being replaced. Find a supplier who can deliver
small amounts of chemicals on short notice and who will accept unopened
chemicals that are returned.
Waste minimization includes recycling and other means to
reduce the amount of waste that must be treated and/or disposed. Waste
minimization addresses “end of pipe” reduction or reuse potential.

Swapmeet. Check the Swapmeet before purchasing or disposing
of chemicals or equipment - somebody may have or need your item!
recovery - If you regularly generate spent solvents, recovery can be
very cost-effective, as well as environmentally sound. Spent
solvents that are properly segregated can be easily distilled in-house to
a high purity that will allow multiple reuse of the same batch of
solvent. Many solvents are excellent candidates for distillation,
including xylene, methanol, acetone, and toluene. Some exceptions
are peroxide-forming solvents, which should not be distilled, and ethanol,
which may require a permit for distillation.
recovery – Practice methods to recover heavy metals such as mercury
and silver. Some suppliers may take back such wastes for credit
