Adding Value to Recovered Liquid Organics through Evolving Technology

2014 NW Hazardous Waste Mgmt. Conference

Marc McReynoldsGeneral Manager, Industrial Sales & OperationsEmerald Services, Inc.

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% Aerosols, Organic Solvents, Oil Based Paint

Latex Paint 30-40% Toxics 10-20%

Pesticides, fertilizers Corrosive, aqueous wastes & pool chems

5-15% Automotive Fluids

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 paintsValue = potential for secondary use or

fuel substitution/both economic & environmental or sustainable

Potential End Uses

Oil Direct burn or refine

Antifreeze Recycling and reformulate

Solvents Paint clean up/gun cleaner

Gas & Diesel 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

From automotive source Separate from other collection materials Recycled through reverse osmosis &

filtration Low tech – needs to be blended with other

Distillation & Filtration 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

Batch vs. Continuous Fractionation vs. simple distillation

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!
