management of
hazardous wastes
Hazardous and Solid Waste
Amendments (HSWA) - 1984
Established three categories of generators
• Large Quantity Generators (LQGs)
(generate over 1000 Kg of hazardous waste per month)
• Small Quantity Generators (SQGs)
(generate between 100 & 1000 Kg and <1 Kg of acutely
toxic waste per month)
• Conditionally Exempt Small Quantity Generators (CESQGs)
(generate less than 100 Kg and <1 Kg of acutely toxic
waste per month)

Defined
Hazardous Waste Categories
•
Listed Wastes (U, P, K, and F)
•
•
•
from commercial chemical products
from specific and non-specific sources
Characteristic Wastes (D)
•
•
based on waste qualities
heavy metals and certain pesticides
Listed Wastes (U, P) –
Commercial Chemicals
“U” listed wastes (“toxic”)
• Acetone
• Formaldehyde
• Phenol
“P” listed wastes (“acutely toxic”)
• Osmium Tetroxide
• Sodium Azide
• Sodium Cyanide
Listed Wastes (K, F) – Specific
and Nonspecific Sources
“K” listed wastes (“specific sources”)
• Distillation bottoms from the production of acetaldehyde
from ethylene
• Wastewater treatment sludges generated in the production of
creosote
“F” listed wastes (“non-specific sources”)
• Spent halogenated solvents (e.g. carbon tetrachloride)
• Spent non-halogenated solvents (e.g. toluene, MEK)
Characteristic Wastes – “D” Wastes
Ignitable
•
flash point  140 F
o
Corrosive
•
pH  2 or  12.5
Reactive
•
•
unstable
air/water reactive
Toxic
•
•
heavy metals
certain pesticides

Waste Minimization Program
• inventory management
• substitution
• microquantities
• drain disposal
• neutralization
• recycling
Inventory Management
Purchase and store only those chemical
quantities to be used over a short period of time
Substitution
Substitution of hazardous chemical
with one that is less or non-hazardous
Use of Material
Safety Data Sheets in
selecting potential
chemicals for
substitution
Microquantities
Use of smaller quantities of chemicals can result
in smaller volumes of hazardous wastes
Drain Disposal
Only for certain chemicals in small quantities
with appropriate dilution and POTW approval
Elementary Neutralization
Proper neutralization of hazardous chemicals can
result in reduced hazardous waste generation
Recycling through Distillation
Solvent distillation reduces waste volumes and
and extends the time between needed purchases
Orphan
Chemical Program
• Transfers useable but unwanted
chemicals to those who can use them
• reduces disposal costs
• reduces purchasing costs for new
materials
