Adding Value to Recovered Liquid Organics through Evolving Technology 2014 NW Hazardous Waste Mgmt. Conference  Marc McReynolds General Manager, Industrial Sales & Operations Emerald 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 paints Value = 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!!!
