Glycol & Antifreeze Recycling and Waste Management 

 Glycol & Antifreeze Waste Services 

Used Antifreeze Collection and Recycling

Valicor provides collection and management services for used antifreeze generated by industrial facilities, maintenance operations and commercial fleets.

Depending on the characteristics of the material and available outlets, used antifreeze may be directed toward recycling, recovery or another appropriate treatment process.

Common materials include:

• Used automotive antifreeze
• Industrial coolant
• Ethylene glycol solutions
• Propylene glycol solutions
• Mixed water and antifreeze
• Off-spec coolant
• Expired or unused antifreeze products
• Coolant removed during equipment maintenance

Valicor can help determine an appropriate outlet based on the composition, volume and condition of the material.

Ethylene Glycol Waste Management

Ethylene glycol remains common in automotive, industrial and cooling applications.

Waste streams may include relatively clean used coolant or more complex mixtures containing water, oils, metals, treatment chemicals or other contaminants.

Valicor provides collection and management options for:

• Used ethylene glycol
• Antifreeze and coolant
• Cooling-system wastewater
• Equipment drain-down fluids
• Contaminated glycol mixtures
• Flushwater containing residual glycol
• Tank and system cleanout liquids

Waste characterization helps determine whether recycling, recovery, wastewater treatment or another management option is appropriate.

Data Center Glycol and Cooling System Waste

Modern data centers rely on increasingly sophisticated cooling infrastructure, including chilled-water systems, closed cooling loops and liquid cooling technologies.

These systems can generate glycol-containing wastewater during both construction and ongoing operations.

Valicor supports data center operators, mechanical contractors and commissioning teams with waste generated from:

• Initial cooling-system fills and flushes
• Mechanical system commissioning
• Chilled-water loops
• Glycol cooling loops
• Closed-loop drain-downs
• Cooling-system maintenance
• Cooling fluid replacement
• Equipment upgrades and retrofits
• Off-spec coolant
• High-volume flushwater

Our combination of transportation resources and wastewater treatment facilities allows Valicor to support projects ranging from routine maintenance to major data center construction and commissioning activities.

Recycling, Treatment and Resource Recovery

Not every glycol-containing waste stream is the same, and not every stream follows the same management path.

Material may vary based on:

• Glycol concentration
• Type of glycol
• Water content
• Oil contamination
• Metals or suspended solids
• Corrosion inhibitors
• Biocides
• Cleaning chemicals
• Other process contaminants

Valicor evaluates the characteristics of the waste stream to determine an appropriate management option.

Depending on the material and available outlets, that may include recycling, recovery, centralized wastewater treatment or other responsible disposal methods.

Our goal is to identify a practical solution while helping customers meet operational, compliance and sustainability objectives.

Propylene Glycol Wastewater

Propylene glycol is used in a growing range of cooling and heat-transfer applications, including data center and HVAC systems.

During flushing, maintenance or fluid replacement, these systems can generate wastewater containing varying concentrations of propylene glycol.

Valicor can manage:

• Dilute propylene glycol wastewater
• Concentrated glycol solutions
• Water generated during system flushing
• Cooling-loop drain-down water
• Glycol mixed with corrosion inhibitors or treatment chemicals
• Off-spec propylene glycol mixtures
• Rinse water from glycol tanks and equipment

Whether a project generates a few containers or multiple tanker loads, Valicor can help evaluate transportation and treatment options based on the waste profile.

Cooling System Flushwater and Drain-Down

A cooling system does not have to contain high concentrations of glycol to create a glycol-related waste stream.

During commissioning, maintenance or system changeouts, large quantities of water may be circulated through piping and equipment to remove residual glycol, treatment chemicals, debris or other material.

Valicor provides transportation and treatment solutions for:

• Closed-loop system flushing
• Chiller flushing
• Mechanical piping flushwater
• HVAC system drain-down
• Glycol loop maintenance
• Cooling-system cleaning
• Equipment replacement projects
• System commissioning and startup

For large-volume projects, Valicor can help coordinate tanker transportation and treatment capacity to keep work moving without unnecessary delays.

Transportation & Logistics Services

Managing glycol wastewater often requires more than simply finding a disposal outlet.

Valicor can coordinate transportation for both recurring waste streams and one-time projects, including:

• Bulk tanker service
• Vacuum truck service
• Drum and tote collection
• Scheduled pickups
• High-volume project support
• Maintenance shutdowns
• Construction and commissioning projects
• Emergency and time-sensitive service

For projects generating large quantities of flushwater or cooling-system waste, transportation and treatment capacity can be coordinated in advance to help reduce disruption to the project schedule.

Industries We Support

Valicor manages antifreeze and glycol-containing waste for a wide range of industries and applications, including:

• Data centers
• Manufacturing facilities
• Automotive manufacturing and service operations
• Commercial fleets
• Warehouses and distribution facilities
• HVAC and mechanical contractors
• Construction and commissioning contractors
• Utilities and power generation
• Chemical manufacturing
• Food and beverage facilities
• Industrial maintenance operations
• Commercial and institutional facilities

Any operation using glycol as a coolant, antifreeze or heat-transfer fluid may eventually need an outlet for spent fluid, contaminated material or system flushwater.

Common Glycol & Antifreeze Waste Valicor Handles

Valicor can evaluate a broad range of glycol-related liquid wastes, including:

• Used antifreeze
• Ethylene glycol
• Propylene glycol
• Dilute glycol wastewater
• Concentrated glycol solutions
• Glycol and water mixtures
• Cooling-loop wastewater
• Chiller drain-down water
• Closed-loop cooling water
• Cooling-system flushwater
• HVAC wastewater
• Off-spec antifreeze and coolant
• Expired cooling fluid
• Tank rinse water
• Equipment cleanout water
• Glycol containing corrosion inhibitors
• Glycol containing treatment chemicals
• Contaminated coolant
• Construction and commissioning flushwater

Acceptance and final management options depend on waste characterization and facility capabilities.

Nationwide Network for Glycol and Antifreeze Waste Management

Valicor's network of wastewater treatment facilities and transportation resources allows us to support customers across a broad geographic footprint.

For companies operating multiple facilities, construction contractors moving between projects, or data center operators developing campuses in multiple markets, that network can provide a more consistent approach to liquid waste management.

Our facilities support industrial customers throughout major markets across the Midwest, Southeast, Texas and South-Central United States, Mid-Atlantic and Rocky Mountain regions.

Whether you are managing routine antifreeze collection, draining a cooling loop or preparing for a large commissioning flush, Valicor can help evaluate the waste stream and determine an appropriate next step.
