4.5.9
Hazardous Waste Minimization Program.  This program was established
to provide guidance in reducing hazardous waste generation at all military
installations.  Each of the services' research laboratories is pursuing research
and development work to find a less toxic or biodegradable material as an
environmentally acceptable substitute.  Likewise, process modification involving
the incorporation of any additional equipment or changes in the process itself
has been investigated.  Examples of process modifications that have been
implemented are
1.
plastic media blasting
2.
zero rinse discharge hard chrome plating
3.
can crushing
4.
sludge dewatering
5.
4.5.9.1
Plastic media blasting is a process for stripping paints from
aircraft using plastic media instead of methylene chloride.  The plastic media
is a less toxic material, and hazardous waste generation has been reduced up to
90% in paint stripping applications.
4.5.9.2
Zero rinse discharge hard chrome plating is a process for
recirculating plating rinse water to the plating bath instead of discharging it
to the industrial treatment plant.  This process modification has reduced
plating wastes up to 80%.
4.5.9.3
Can crushing is a mechanical process for compacting empty
paint cans and contaminated empty drums.  This reduction in volume reduces
disposal costs.
4.5.9.4
Dewatering industrial sludges with the use of filter presses
squeezes the water out of the sludge, forming a much thicker sludge cake with
much less volume.
4.5.9.5
Neutralization is a process for mixing acids with bases in
order to decrease the corrosivity of the solution.  This treatment is used for
battery acids prior to disposal to the industrial wastewater treatment plant.
4.5.10 Household Hazardous Waste
4.5.10.1  Household wastes, including household waste that has been
collected, transported, stored, treated, disposed of, recovered (e.g., refuse-
derived fuel), or reused is not regulated as hazardous waste. "Household waste"
means any material (including garbage, trash, and sanitary wastes in septic
tanks) derived from households, residences, hotels, motels, bunkhouses, ranger
stations, crew quarters, campgrounds, picnic grounds, and day-use recreation
areas.  Many household wastes are, however, hazardous in nature and may be
ignitable, corrosive, toxic, or reactive.  A chemical is also considered
hazardous if it may cause a substantial injury, serious illness, or harm to
humans, domestic livestock, or wildlife.  Tables 4-5A and B list common
household and garage chemicals now considered hazardous.
