1. Solvent recycling system
2. RCRA wastewater treatment exemption
3. Manage empty lecture bottles
4. Chemical recycling list (chemical inventory
software also a great option)
5. Packing lists vs. manifests (not reduction but a
means to manage your generator status)

• Initial Purchase : $15,750
(cost sharing with Chemistry Department)
• Projected annual savings: $7,200 FY 2000
(waste disposal as lab pack) dollars
• Payback approximately 2 years
• Savings will vary depending on disposal:
(lab pack, 5 gallon pail, or 55 gallon drum)
• Other Savings: $3,000 annually not having to purchase

o Some wastes generated in
laboratories can be managed
under your wastewater
o Acids in semiconductor
laboratories are a good
o Acids treated are converted
into H2O, NaCl, NaF
(drinking water additive),

o The U.S. EPA promulgated the exemption in 1980 to avoid
imposing duplicative permitting requirements. Without this
exemption, facilities could be subject to both a NPDES
permit or a wastewater pretreatment permit and a hazardous
waste permit for the same treatment unit. The underlying
assumption EPA used in justifying the WWT exemption was
that tanks used to handle hazardous wastewaters at these
facilities would be provided with oversight under the CWA,
thereby ensuring no significant decrease in environmental
protection and control.

o Fits into many laboratory processes better.
o Safer and requires considerably less time.
o Wastes are managed on-site under your
wastewater treatment permit.
o Wastes not reported as hazardous wastes
o Avoid costs associated with disposal as a
8/26/10 2010 ACS National Meeting and Exposition 9
o Many are not returnable.
o Some can easily be de-valved and recycled
for their metal.
o Can be done by researchers, EHS staff or by
certain hazardous waste vendors.
o Managing on site can be frequently less
expensive than disposal.

o Carbon dioxide
o Oxygen (D001)
o Carbon monoxide
o Many calibration
o Inert gases
o Flammable gases
8/26/10 2010 ACS National Meeting and Exposition 11
o Develop a fact sheet to provide guidance.
o Hazardous gases must be less than 25 psi
(RCRA empty) if they need to be purged.
o Purge flammable and hazardous gases with
nitrogen 3 times (try to have researchers do this).
o Some cylinders could require triple rinsing and
may not be worth managing on site.
o Do not de-valve pyrophoric or highly toxic
8/26/10 2010 ACS National Meeting and Exposition 12
o Develop website.
o Mailing list.
o Keep it up to date.
o Best sources are lab
clean outs, lab
moves or retiring
o You will be amazed
what people take.

o Manifests on average can
overstate the amount of
regular hazardous waste
you ship by up to 50%.
o P listed waste can be
overstated by 450% or
o Don’t count the weight of
the drum and vermiculite
as hazardous waste.

“Well, President Obama said today he’s going to use the gulf
disaster to immediately push a new energy bill through
Congress. I got an idea. How about first using the gulf disaster
to fix the gulf disaster?” - Jay Leno
“Scientists say they have developed a car that can run on water.
The only catch is, the water has to come from the Gulf of
Mexico.” -Jay Leno
“This oil spill in the Gulf is affecting everybody. In fact, when I
went to lunch this weekend and ordered the sea bass, they
asked if I wanted it regular or unleaded.” - David Letterman
