What do I know?



DEQ HHW Experience
Commercial Sales Experience (facilitated
management of wide variety of
hazardous waste to facilities & end-users)
Specific recycling experience



Material substitution
E-Waste/Universal Waste
Part B Permit Mgmt Experience

Various recycling processes at facility
Goals for discussion





Outline typical wastes
Discuss value streams
Specify potential end uses
Discuss various options for management
Other considerations in decisions
Perhaps foster some ideas to tweak
collection or current program to divert more
to recycle
Types of Waste-Typical HHW Collection

Flammables 40-60%



Latex Paint 30-40%
Toxics 10-20%


5-15%
Automotive Fluids


Pesticides, fertilizers
Corrosive, aqueous wastes & pool chems


Aerosols, Organic Solvents, Oil Based Paint
Antifreeze/Oil (Typical separate collection)
Batteries, Mercury Debris, PCB Ballasts, Reactives,
Organic Peroxides,
Organic Value Waste Streams
DIY Oil
 DIY Antifreeze
 Paint thinners, clean up solvents
 Gas & Diesel
 Oil based paints
Value = potential for secondary use or fuel
substitution/both economic &
environmental or sustainable

Potential End Uses

Oil


Antifreeze


Paint clean up/gun cleaner
Gas & Diesel


Recycling and reformulate
Solvents


Direct burn or refine
Fuel use
Oil based paints

Btu substitution
Planning for reuse

Any reuse/recycling option material
typically must meet a “processing”
specification




Oil = water, pcbs, halogens
Glycol = source, % glycol
Solvents = % solids, water, like with like
Oil based paints = % solids, btu, water
Separate and manage at source will
increase likelyhood of value.
Oil
• Blend to burner specification
• Ash, sulfur, water, solids
• Re-refine
• Create higher use fuel
• Low Sulfur Marine Diesel
• Other By-Products
• Base stock
• Added back into lube oil
Oil-cont.
Different forms of distillation
change collected oil.
• Composition of oil changes
outcome
• Synthetic, semisynthetic
• By products of refining
• Water, lights
• Middle cut
• Flux
Antifreeze

Must meet specifications for recycle



Separate from other collection materials
Recycled through reverse osmosis &
filtration


Low tech – needs to be blended with other
Distillation & Filtration



From automotive source
Energy intensive
Removes contaminants & impurities
Add additives back to meet ASTM
standards for automotive use
Solvents

Separate types – aliphatic from aromatic

Typified by use





Paint cleaning vs. grease & oil clean up
Eliminate cross contamination and water
Most likely products are industrial grade
cleaners
Goal to match waste feedstock to end
product use
What to look for:

Acetone, MEK, Toluene, Branded Thinners,
Alcohols
Solvents

Distillation then becomes cleaner


Fractionation vs. simple distillation




Batch vs. Continuous
Thin film
Pots
Column
Remove some water



Although some solvents soluable with water
Good solvent
Still bottoms
Gas/Diesel


Separate from oils and water
If clean and segregated can be
managed for intended use as fuel

May be sent to specialty processor to re
refine
Oil Based Paints

Eligible for fuel substitution program at
cement kiln


Higher btu and lower water equals higher
value
Sludge and debris makes more difficult to
handle


Cannot pump, when filled tanks or vessels
must clean out
How collected


Loosepack
Thin liquids vs. bulk all
Factors in diversion


Program costs
Education of workers and vendors




Not all vendors may be able to provide
services
Weighting of green/sustainable goals
How segregation may change
composition of current streams
Opportunity to return product back to
homeowner

Close the Loop!!!
Thanks very much for attention and interest!
