As
a generator of hazardous waste, Rutgers University
is required by the Environmental Protection Agency
to implement waste minimization techniques. The
goal is to reduce the volume and/or the toxicity
of hazardous waste generated. Please read the
information below on the specific types waste
minimization.

Chemical Reuse
Unused
and unopened chemicals being disposed of as waste,
due to a change in research or discontinuation
of a specific research protocol, will be redistributed
to other laboratories that can utilize the chemical.
Sharing unused chemicals will reduce the amount
of chemical waste generated. Specific applicable
chemicals (typically stable compounds with a long
shelf life) will be picked up by REHS and segregated
in the ESB. These chemicals are cataloged on a
list, which is available on our web page (See
link below). The Environmental Services
Group will deliver the chemical(s) to your laboratory.
Chemicals being redistributed will be tracked
on a spreadsheet by REHS.

Microscaling
Microscale
chemistry is a pollution prevention method that
decreases the amount of chemical waste generated
during laboratory experiments. This concept was
first introduced by chemistry professors at Bowdoin
College in Brunswick, Maine. Standard chemistry
procedures are re-written for individual experiments
and specialized microscale equipment is utilized
to perform the work. In some cases, the
amount of a particular chemical needed for an
experiment has been decreased by as much as 99
percent.
Microscaling has the following benefits:
- Reduce
chemical waste produced at the source.
- Improve
laboratory safety by decreasing potential exposure
to chemicals and reducing fire and explosion
hazards.
- Improve
air quality due to greatly reduced volumes of
solvents and other volatile substances used.
- Reduce
laboratory costs for chemical purchase and disposal.
- Reduce
the time required to perform experiments due
to shorter chemical reaction times.
- Decrease
the amount of storage space necessary for chemicals.
- Encourage
students to think about waste minimization.
- Decrease
disposal costs for the University
- Increase
environmental awareness for the University

Inventory Control
Each
laboratory is encouraged to maintain an appropriate
inventory of chemicals in their laboratory as
a method to reduce unnecessary purchase and disposal.
The following methods can reduce the amount of
chemicals in a laboratory and minimize waste generated
from expired or unwanted excess chemicals:
- Check
your laboratory inventory and the REHS chemical
redistribution list before ordering.
- Purchase
smaller containers of chemicals or fewer containers
of chemicals.
- Avoid
purchasing larger quantities of chemicals to
save on raw material costs. (Chemical disposal
costs are often much higher than the initial
purchase cost.)
- Do
not accept icfreeló samples from chemical
manufacturers, unless you are certain that you
will be using the materials. (Again, chemical
disposal costs are often much higher than the
initial purchase cost.)
- Rotate
stock of chemicals in the laboratory to ensure
the older chemicals are used before the newer
chemicals.

Substitution of
Less Hazardous Chemicals
In some
instances, chemicals that are more environmentally
friendly may be substituted for traditionally
used chemicals.
Examples:
|
Propylene
glycol
|
instead
of
|
Ethylene
glycol
|
|
Ethyl
alcohol
|
instead
of
|
Methyl
alcohol
|
|
Alcohol
thermometers
|
instead
of
|
Mercury
thermometers
|
|
Alconox,
Pierce RBS35 and Nochromix
|
instead
of
|
Chromic
acid cleaning solutions
|
|
Detergent
and hot water
|
instead
of
|
Organic
solvent cleaning solutions
|
This
Hazardous waste policy is designed to provide guidance
for everyone at Rutgers University regarding the
proper disposal of hazardous waste. |
